Essential First 90 Days Roadmap New Solar Installers

Starting a solar installation business in India can feel like a sprint through a maze of permits, leads, and calculations. The first 90 days roadmap new installers follow is critical: it sets the foundation for compliance, sales flow, and cash‑cycle discipline. In a market energized by the PM Surya Ghar mission to reach one crore households, the window for capturing early projects is short. A disciplined plan helps you move from a spreadsheet‑driven hobby to a professional operation that can generate subsidy‑aware proposals, manage WhatsApp leads, and track installations end‑to‑end.

During the first three months you will need to (1) register your business and obtain MNRE vendor status, (2) get empanelled with local DISCOMs, (3) put a simple CRM in place, (4) build a lead‑generation engine that respects local search habits, (5) run site surveys and produce GST‑compliant quotations, (6) secure the first EPC contracts, and (7) lay the groundwork for post‑sale services such as AMCs and cleaning. Each of these steps is inter‑linked; missing a compliance touchpoint can stall a deal, while a weak lead funnel can leave you idle despite having all licences in place.

This guide walks you through each milestone with practical checklists, sample tables, and links to official resources. By the end of the 90‑day period you should have at least one signed residential project, a pipeline of qualified leads, and a clear picture of your gross margin per kW. The roadmap is built for small‑ to mid‑size installers who rely on local teams, WhatsApp communication, and affordable software tools rather than large enterprise suites.

Quick Answer: Follow the 7‑step 90‑day plan to register, get DISCOM empanelment, set up a simple CRM, generate WhatsApp leads, run surveys, submit GST‑aware proposals, and close the first EPC contract.

First 90 Days Roadmap New – Why This Matters

The Indian rooftop solar market is at a turning point. The “PM Surya Ghar” mission aims to install solar on 1 crore households, and the cost of a 1 kW system has been falling steadily for the last few years. For a small‑ or mid‑size installer, the next three months can decide whether the business rides this wave or gets left behind.

The Opportunity Landscape

Aspect	Traditional Approach	Modern, Software‑Enabled Approach
Lead Capture	Paper forms, ad‑hoc phone logs	WhatsApp‑integrated CRM, local SEO tools
Quote Generation	Manual spreadsheets, guesswork on GST and subsidies	Automated proposal builder that inserts the latest GST split and MNRE subsidy values
Compliance	Separate spreadsheets for vendor registration, GST filing, DISCOM empanelment	One platform tracks every compliance touch‑point and sends reminders
Project Tracking	Physical checklists, Excel sheets	Real‑time dashboard of site surveys, installations, and post‑sale service
Post‑Sale Service	Phone calls, ad‑hoc scheduling	AMC management, cleaning contracts, and upgrade offers linked to each system

The table shows that relying on spreadsheets and scattered WhatsApp chats creates hidden costs: duplicated effort, missed subsidies, and slower response times. When a homeowner asks for a quote, the installer must calculate the GST split (70 % goods, 30 % services) and apply any state‑specific subsidy. Missing a step can turn a profitable job into a loss, or worse, a regulatory breach.

The Cost of Inaction

A new installer that spends the first 90 days juggling manual tools will see a higher cost per lead and a lower lead‑to‑survey conversion. In competitive cities like Delhi, Mumbai, or Bengaluru, rivals who already use an integrated operating system can respond to WhatsApp enquiries within minutes, generate a GST‑aware proposal in seconds, and move the customer to site survey within a day. The lag created by manual work often means the prospect chooses a faster competitor.

What the First 90 Days Can Unlock

Speed to Quote – An automated proposal generator can produce a compliant quote in under five minutes, allowing the installer to capture the prospect’s interest while it is hot.
Accurate Subsidy Capture – By linking to the latest MNRE guidelines, the software ensures every eligible homeowner receives the maximum benefit, increasing the win‑rate.
Compliance Confidence – The platform logs vendor registration, DISCOM empanelment, and GST filing deadlines, reducing the risk of penalties.
Data‑Driven Decisions – Real‑time dashboards show the cost per lead, survey‑to‑close ratio, and gross margin per kW, enabling the installer to fine‑tune marketing spend.

Building a Sustainable Business Stack

A typical installer’s stack now looks like this:

Lead Generation – Local SEO, Google Ads, WhatsApp, referrals.
CRM & Communication – Centralised inbox that records every chat, call, and email.
Site Survey Tool – Mobile app that captures roof dimensions, shading, and structural notes.
Proposal Software – Generates GST‑aware, subsidy‑adjusted quotations.
Project Management – Tracks procurement, installation, and hand‑over.
Post‑Installation Service – AMC contracts, cleaning schedules, and upgrade offers.

Each block feeds the next, and the first 90 days are the ideal window to stitch them together. By the end of the period, the installer should have a repeatable workflow that moves a lead from WhatsApp message to signed contract in under two weeks for residential projects and under a month for commercial deals.

The Role of the Operating System

The operating system for solar installers brings all these blocks onto a single cloud‑based platform. It does not sell panels, inverters, or batteries – it simply gives installers the digital backbone they need to compete. By consolidating lead capture, proposal generation, subsidy calculation, GST compliance, and installation tracking, the system removes the need for multiple spreadsheets and disjointed apps.

In the first three months, the installer can focus on three core activities:

Data Migration – Import existing leads, customer contacts, and past project details into the CRM.
Process Definition – Map out each step – from lead capture to post‑sale service – within the platform’s workflow builder.
Team Enablement – Train field staff and office personnel on using WhatsApp integration, proposal templates, and the installation dashboard.

When these steps are completed, the installer gains a single source of truth for every project, which translates into faster closures, higher margins, and smoother compliance.

What to Expect After 90 Days

Lead‑to‑Survey Rate improves by 20‑30 % as prospects receive instant, accurate quotes.
Survey‑to‑Close Rate rises because the proposal already reflects the correct GST split and subsidy, eliminating last‑minute price negotiations.
Gross Margin per kW stabilises as the installer no longer loses money on mis‑calculated GST or missed subsidies.
AMC Attach Rate climbs when the system automatically schedules post‑installation follow‑ups and offers cleaning contracts.

In short, the first 90 days are not just a timeline; they are a strategic runway. By building a digital foundation now, installers position themselves to capture a slice of the fast‑growing rooftop market, stay compliant with GST and MNRE rules, and grow without burning cash.

Common Misconceptions

Myth 1 – “I can manage everything with WhatsApp and Excel.”

Reality: WhatsApp is excellent for instant communication, but it does not store structured data, enforce GST calculations, or track installation milestones. A spreadsheet can quickly become outdated, leading to missed subsidies or GST errors. Integrating WhatsApp with a CRM keeps the conversation linked to the customer record, while the platform handles the heavy lifting of compliance.

Myth 2 – “GST on solar is a fixed 5 % and I can apply it manually.”

Reality: The GST treatment for solar systems follows a 70:30 goods‑to‑services split, which means the tax component is calculated differently for equipment versus installation services. The exact rate can vary with changes in tax law, and a manual approach risks mistakes. Using a tool that automatically applies the current split and prompts you to confirm the rate with a Chartered Accountant safeguards against costly errors.

Myth 3 – “Subsidy calculations are too complex; I’ll just ignore them.”

Reality: Ignoring MNRE subsidies reduces the customer’s out‑of‑pocket cost, making your quote less attractive. The subsidy amount depends on system size, state policy, and the installer’s vendor registration status. An automated calculator pulls the latest figures, ensuring every eligible homeowner receives the maximum benefit, which in turn improves the win‑rate.

Myth 4 – “DISCOM empanelment is a one‑time paperwork task.”

Reality: Empanelment requires ongoing compliance checks, such as updating ALMM‑listed component lists and renewing certifications. A manual tracker can miss renewal dates, leading to disqualification from government‑backed projects. A platform that flags upcoming deadlines and stores all required documents keeps the installer continuously eligible.

Myth 5 – “I don’t need an AMC; most customers handle maintenance themselves.”

Reality: Post‑installation service is a high‑margin revenue stream. Offering a structured AMC, cleaning contract, or upgrade path increases customer lifetime value and smooths cash flow. When the operating system schedules service calls and sends reminders, the installer can maintain a high attach rate without extra administrative burden.

Myth 6 – “Scaling means hiring more salespeople first.”

Reality: Scaling without a digital backbone often leads to duplicated effort and lost data. By first automating lead capture, proposal generation, and project tracking, the installer can handle more leads with the same headcount. For deeper insights on cash‑efficient growth, see the article on Growth Without Burning Cash: Sustainable Solar Scaling for Installers.

Myth 7 – “All software solutions are the same; I can pick any CRM.”

Reality: Generic CRMs lack solar‑specific features such as GST split calculators, subsidy integration, and DISCOM empanelment tracking. A purpose‑built operating system for Indian installers bridges that gap, ensuring every proposal is compliant and every installation is logged.

By debunking these myths, new installers can focus on building a repeatable, compliant, and profitable workflow rather than fighting the same avoidable hurdles repeatedly.

First 90 Days Roadmap New Solar Installers — how it works / what you must know

The first three months are a blend of paperwork, technology setup, and market outreach. Below each pillar is broken into actionable sub‑tasks.

1. Legal Foundations and Registrations

Task	Description	Typical Time
Business incorporation (LLP/Private Ltd.)	Register with MCA, obtain PAN & TAN.	7‑10 days
GST registration	Apply online; note the composite supply rule for solar.	5‑7 days
MNRE vendor registration	Submit detailed company profile, past project list, and financials.	15‑20 days
DISCOM empanelment	Provide MNRE certificate, GSTIN, and safety approvals.	20‑30 days

Why it matters: Without MNRE vendor status you cannot claim the central subsidy, and DISCOM empanelment is required for net‑metering approvals. Keep digital copies of all certificates; many DISCOM portals request PDFs during project onboarding.

2. Build a Simple, Lead‑Focused CRM

Most new installers start with spreadsheets, but a purpose‑built CRM reduces errors and speeds up quoting. Look for tools that:

Capture leads from WhatsApp, Google Ads, and local SEO.
Store site‑survey notes and photographs.
Generate PDFs that can be edited with subsidy and GST calculations.

A lightweight SaaS platform that integrates with WhatsApp Business API can replace manual logs within a week of trial.

3. Lead Generation Engine

a. Digital Channels

Local SEO: Optimize for “rooftop solar installer in [city]”. Use Google My Business, add photos of completed jobs, and encourage happy customers to leave reviews.
Google Ads: Run a modest daily budget (₹1,000‑₹2,000) targeting “solar rooftop cost” and “solar subsidy”. Track cost‑per‑lead (CPL) to keep the funnel affordable.

b. Offline Touchpoints

Referral partnerships: Connect with electricians, architects, and real‑estate agents. Offer a small referral fee per qualified lead.
Community events: Participate in local housing society meetings; many societies are now exploring solar under the Surya Ghar scheme.

4. Site Survey and Data Capture

A quick site visit (30‑45 minutes) should collect:

Roof area and orientation.
Shading analysis (use a simple smartphone app or a shade‑balloon).
Existing electrical load (kWh from the last 12 months bill).
Customer’s budget expectations.

Enter these details directly into the CRM; the next step is an automated proposal.

5. Proposal Generation with Subsidy & GST Awareness

Your proposal must clearly separate:

Equipment cost (goods) – panels, inverters, mounting.
Installation services (services) – labour, wiring, commissioning.
Subsidy amount – based on MNRE guidelines and state‑specific caps.
GST calculation – apply the 70:30 split, then the appropriate GST rate.

Using a template that pulls data from the CRM reduces manual errors. Attach a copy of the MNRE subsidy calculator for transparency.

6. Closing the EPC Contract

Once the customer signs the proposal, issue a GST‑compliant invoice. Key points:

Mention “Composite Supply of Solar Power Generating System” in the description.
Include your GSTIN and the customer’s PAN (if applicable).
Align the project start date with the DISCOM’s net‑metering inspection schedule.

7. Post‑Installation Service Blueprint

Early after‑sales service builds trust and creates repeat business:

AMC enrollment: Offer a 2‑year maintenance contract at a modest percentage of the EPC value.
Cleaning schedule: Quarterly cleaning can be a standalone revenue stream.
System upgrade path: Keep a record of battery or inverter warranty expiry for future upsell.

External Guidance

For the latest subsidy caps and eligibility, refer to the official MNRE portal: MNRE Solar Subsidy Guidelines.

By following these seven pillars, a new installer can move from zero to a live project pipeline within 90 days, while staying compliant and profit‑focused. The roadmap is flexible—adjust timing based on local DISCOM response times, but never skip the registration or GST steps, as they are deal‑killers if overlooked.

First 90 Days Roadmap New — costs, savings and returns

Understanding the financial picture in the first three months helps you set realistic targets and avoid cash‑flow surprises. Below is a breakdown of typical cost ranges and expected returns for a small‑to‑mid‑size installer launching in a Tier‑2 city.

1. Startup Cost Snapshot

Expense Category	Typical Range (INR)	Notes
Business registration & licences	15,000‑30,000	Includes MCA filing, GST registration, MNRE vendor fee
DISCOM empanelment fees	10,000‑25,000	Varies by state; may require site‑visit charges
CRM / SaaS subscription (basic plan)	5,000‑12,000 per month	Look for WhatsApp integration and proposal templates
Lead generation (Google Ads + SEO)	10,000‑25,000 per month	Adjust based on CPL and conversion
Survey tools (smartphone tripod, shade app)	3,000‑7,000	One‑time purchase
Miscellaneous (office rent, utilities)	8,000‑15,000 per month	Small coworking space or home office

Total initial outlay (first month): roughly ₹51,000‑₹114,000.

2. Revenue Projection from First EPC Contract

Assume you close a residential rooftop system of 5 kW (average for a middle‑income home).

Average EPC price (incl. goods & services): ₹70,000‑₹85,000 per kW → ₹350,000‑₹425,000 total.
Subsidy (central + state): typically 10‑30 % of equipment cost; for a 5 kW system this could be ₹35,000‑₹105,000 (exact amount confirmed with MNRE calculator).
GST payable: calculated on the net amount after subsidy; the exact rate must be validated with a CA.

3. Gross Margin Estimate

Industry observations suggest a gross margin of 12‑20 % per kW after accounting for component cost, labour, and GST. For a 5 kW job:

Metric	Low End	High End
Gross profit (₹)	42,000	85,000
Gross profit per kW (₹)	8,400	17,000

4. Payback Period for Startup Investment

Using the high‑end gross profit (₹85,000) and the maximum initial outlay (₹114,000), the payback period is roughly 1.3 months after the first project is invoiced and paid. This quick recovery is typical when the sales cycle is short (days to weeks) for residential deals.

5. Upsell and Recurring Revenue

AMC (2‑year): 5‑7 % of EPC value per year → ₹17,500‑₹29,750 annually.
Panel cleaning: ₹500 per visit per kW → ₹2,500 per cleaning cycle for a 5 kW system.
System upgrades (battery addition after 2‑3 years) can add another 5‑10 % of the original EPC value.

6. Sensitivity Table

Variable	Impact on Gross Margin
Higher subsidy (30 % vs 10 %)	Increases margin by ~5 % per kW
Faster lead‑to‑survey conversion	Reduces CPL, improves cash‑flow
Delayed DISCOM approval	Pushes project start, may affect cash‑flow
Use of advanced CRM (higher fee)	Slightly higher fixed cost but improves close rate

The numbers above illustrate that even a modest first project can cover the early expenses and generate a healthy profit margin, provided the installer follows the compliance checklist and uses a streamlined proposal workflow. Keep tracking the key metrics—cost per lead, lead‑to‑survey rate, and gross margin per kW—to refine your strategy in the next 90‑day cycle.

First 90 Days Roadmap New – Use Cases and Scenarios

1. Residential Lead Journey in Delhi

An installer receives a WhatsApp message from a homeowner interested in a 5 kW rooftop system. With a dedicated CRM, the chat is automatically attached to a new lead record. Within minutes, the installer launches the built‑in site‑survey tool on a tablet, records roof dimensions, shading analysis, and uploads photos. The platform then generates a proposal that:

Applies the correct 70:30 GST split (rates to be confirmed with a CA).
Inserts the latest MNRE subsidy for a 5 kW residential system.
Calculates the net payable amount in INR, clearly showing the subsidy and GST components.

The homeowner receives the PDF via WhatsApp, signs electronically, and the system schedules a site visit for the next day. After installation, the same platform logs the commissioning date, creates an e‑invoice with GST details, and automatically enrolls the customer in an AMC option. This end‑to‑end flow reduces the lead‑to‑close cycle to under ten days, a competitive advantage in a market where speed wins.

2. Commercial Solar Pitch in Bengaluru

A small‑scale commercial client seeks a 30 kW system for a warehouse. Commercial cycles are longer, often involving multiple decision‑makers. In the first 90 days, the installer sets up a multi‑stage workflow:

Stage 1 – Qualification: Capture the client’s energy bills via a secure upload portal.
Stage 2 – Technical Survey: Use the mobile app to record roof load‑bearing capacity and shading.
Stage 3 – Financial Model: The proposal engine produces a detailed cash‑flow analysis, including GST impact, potential subsidies, and payback period.

Because the platform stores every document and tracks approvals, the installer can quickly respond to queries from the client’s finance team. The structured workflow also helps the installer stay compliant with DISCOM empanelment requirements, as all component selections are cross‑checked against the ALMM list.

3. Handling Negotiation & Discount Requests

Negotiation is inevitable, especially for larger commercial deals. An installer can reference the article on Handling Negotiation & Discount Requests in Solar Sales to adopt a disciplined approach:

Transparent Cost Breakdown: The proposal shows the GST split and subsidy, making it harder for the client to argue for arbitrary discounts.
Value‑Based Add‑Ons: Instead of cutting price, the installer can offer a free first‑year cleaning contract or a discounted AMC, preserving margin.

By having all cost components visible in the system, the installer can negotiate confidently and maintain profitability.

4. Capital Planning for a New Business in Chennai

Before the first 90 days are over, the installer needs to understand the cash requirements for scaling. The internal article on How Much Capital Do You Need to Start a Solar Business? outlines the key expense buckets:

Software subscription (covers CRM, proposal generator, and compliance tracker).
Field equipment (tablet for surveys, portable solar irradiance meter).
Marketing spend (local SEO, Google Ads, WhatsApp broadcast).

By plugging the actual numbers from the operating system’s dashboard—such as cost per lead and average gross margin per kW—the installer can create a realistic cash‑flow forecast. This financial clarity helps in securing bank loans or investor funding without over‑leveraging.

5. Post‑Installation Service as a Growth Engine

After the first 90 days, the installer has a portfolio of installed systems. The platform’s AMC module automatically sends service reminders, tracks cleaning schedules, and logs any upgrade requests (e.g., adding battery storage). Each service call is an opportunity to upsell, turning a one‑time installation into a recurring revenue stream. Over time, the attach rate for AMC contracts can become a primary source of profit, especially when the installer bundles cleaning with performance monitoring.

6. Scaling Across Multiple Cities

Once the workflow is proven in one city, the installer can replicate it in another state with minimal friction. The operating system’s configuration settings allow for city‑specific GST rates, subsidy schemes, and DISCOM empanelment documents. By cloning the lead‑to‑install pipeline, the installer can open a new branch in Hyderabad while keeping the same data quality standards. This approach aligns with sustainable scaling principles—grow the business without a proportional increase in administrative overhead.

7. Data‑Driven Decision Making

At the end of the first 90 days, the installer reviews the dashboard:

Cost per Lead – How much was spent on Google Ads versus WhatsApp referrals?
Lead‑to‑Survey Rate – What percentage of enquiries turned into site surveys?
Survey‑to‑Close Rate – How many surveys resulted in signed contracts?
Average System Size – Are customers leaning towards 3 kW, 5 kW, or larger installations?

These metrics guide the next quarter’s strategy—whether to invest more in digital ads, focus on larger commercial projects, or improve the survey conversion funnel.

8. Compliance Checklist for the First Quarter

GST Registration – Verify GSTIN, set up e‑invoicing thresholds.
MNRE Vendor Registration – Complete the online portal, upload required certifications.
DISCOM Empanelment – Submit documentation for each state where installations are planned.
ALMM Component List – Ensure all panel, inverter, and mounting hardware are on the approved list.

The operating system sends automated reminders for each of these items, reducing the risk of missed deadlines that could jeopardise subsidy eligibility.

By following this first 90 days roadmap new, installers can transform a chaotic, spreadsheet‑driven operation into a streamlined, compliant, and revenue‑rich business. The key is to digitise every step—from the first WhatsApp ping to the final AMC renewal—so that growth becomes a natural outcome of a well‑engineered process.

First 90 Days Roadmap New: Step‑by‑Step Guide for Indian Solar Installers

Launching or expanding a rooftop solar installation business in India can feel like navigating a maze of regulations, lead channels, and operational tools. The first three months are critical: you must set up compliant processes, generate a reliable lead flow, and close enough projects to fund the next growth phase. Below is a detailed, numbered roadmap that walks a small‑ or mid‑size installer through the essential actions from day 1 to day 90.

Day Range	Focus Area	Key Action	Why It Matters
1‑7	Foundations	Register your firm with the Ministry of New & Renewable Energy (MNRE) as a vendor and begin the DISCOM empanelment process.	Without MNRE registration you cannot claim the residential subsidy, and DISCOM empanelment is mandatory for most subsidised projects.
8‑14	Compliance Setup	Open a GST‑registered business account, configure e‑invoicing thresholds, and note the 70:30 goods‑services split for solar system supplies. Verify the current rates with a chartered accountant.	Correct GST handling prevents costly retro‑adjustments and keeps you eligible for government incentives.
15‑21	Digital Backbone	Choose a cloud‑based operating system that bundles CRM, quotation generation, subsidy & GST calculators, and installation tracking. Limit mention of any brand to a maximum of two references in the whole article.	A single platform replaces spreadsheets, reduces manual errors, and speeds up the proposal‑to‑cash cycle.
22‑28	Lead Generation Engine	Set up local SEO (Google My Business, city‑specific keywords), launch a modest Google Ads budget, and create a WhatsApp Business number for enquiries. Add a simple referral form on your website.	Residential sales cycles in India can be as short as a few days; a steady inbound flow is essential to hit early revenue targets.
29‑35	Lead Qualification	Define cost‑per‑lead (CPL) targets and a lead‑to‑survey conversion benchmark (e.g., 30 % of inbound leads). Use the CRM to tag leads by source and property type.	Tracking CPL and conversion rates lets you optimise spend on the most profitable channels early on.
36‑42	Site Survey Toolkit	Equip your field team with a mobile survey app (or the survey module in your operating system). Capture roof dimensions, shading analysis, and load data in a standard template.	Accurate surveys improve proposal accuracy, reduce re‑work, and increase the survey‑to‑close rate.
43‑49	Proposal Generation	Use the built‑in quotation generator to produce subsidy‑aware proposals that automatically calculate GST and the MNRE rebate. Include a clear payment schedule (e.g., 30 % advance, 40 % on‑site, 30 % after commissioning).	Transparent, compliant proposals build trust with homeowners and speed up decision‑making.
50‑56	Closing the Deal	Follow a structured follow‑up cadence: WhatsApp reminder on day 2, phone call on day 4, and a site‑visit recap email on day 7. If the prospect asks for a discount, refer them to the “Handling Negotiation & Discount Requests in Solar Sales” guide for best practices.	A disciplined follow‑up cadence lifts the typically high close‑rate for residential deals (often within a week).
57‑63	Contract & Documentation	Finalise the sales contract, obtain the customer’s PAN and Aadhaar for subsidy claim, and upload all documents to the central system. Submit the subsidy application through the MNRE portal within 15 days of contract signing.	Timely submission is required to secure the rebate; missing documents can delay cash flow for months.
64‑70	Installation Planning	Create a project schedule in the operations module: assign a site supervisor, order components (ensure they are ALMM‑listed), and book the required electrical safety approvals.	Proper planning avoids idle labour days and keeps the gross margin per kW healthy.
71‑77	Execution & Quality Check	Conduct the installation, perform a commissioning test, and generate a hand‑over report for the customer. Capture photos and system data in the platform for future AMC (annual maintenance contract) upsell.	A clean hand‑over improves customer satisfaction and boosts AMC attach rates.
78‑84	Post‑Installation Service	Schedule the first preventive maintenance visit within 30 days of commissioning. Offer panel cleaning or system upgrade options as part of a value‑added service package.	Early service interactions open additional revenue streams beyond the EPC margin.
85‑90	Review & Scale	Analyse the first‑month metrics: CPL, lead‑to‑survey, survey‑to‑close, average system size, gross margin per kW, and AMC attach rate. Identify the top‑performing lead source and allocate more budget there. Read the “Growth Without Burning Cash: Sustainable Solar Scaling for Installers” article for next‑step financing ideas.	Data‑driven decisions prevent cash burn and set the foundation for sustainable growth beyond the first 90 days.

Detailed Tips for Each Phase

Registration & Empanelment – Keep copies of your MNRE vendor certificate and DISCOM empanelment letters in a cloud folder. Many DISCOMs require you to upload these documents before you can bid on subsidised projects.
GST & Subsidy Calculations – The 70:30 split treats the solar system as a composite supply of goods (70 %) and services (30 %). While the exact GST percentages may change, most installers find it safest to work with a CA who can confirm the current rate before issuing invoices.
Choosing a Software Platform – Look for an all‑in‑one operating system that is purpose‑built for Indian installers. Features to prioritise are WhatsApp lead capture, automatic GST and subsidy calculations, and a visual project timeline.
Lead Generation – In tier‑2 and tier‑3 cities, word‑of‑mouth and local referrals often outperform paid ads. Encourage satisfied customers to share a WhatsApp referral link that tracks back to your CRM.
Survey Accuracy – Use a smartphone app that can export roof measurements in square metres and automatically suggest a system size based on the average Indian load profile (≈ 4 kWh per kW installed).
Proposal Presentation – Include a brief “What you get” table that lists: system size (kW), expected generation (kWh/year), subsidy amount, GST payable, and total out‑of‑pocket cost. Visual clarity reduces back‑and‑forth queries.
Closing Technique – If a prospect hesitates, offer a limited‑time “no‑interest EMIs for 12 months” option, but only after confirming that the GST and subsidy numbers are final.
Documentation Checklist – Customer ID proof, electricity bill (last 3 months), site photos, and a signed provisional acceptance letter. Upload each file to the central repository for audit trails.
Installation Logistics – Pre‑order components at least 7 days before the scheduled start date. Verify that inverters, modules, and mounting structures are on the ALMM list to avoid later compliance issues.
Quality Assurance – After commissioning, run a performance test using a portable data logger. Record the initial output (kWh) and compare it with the design estimate. Any deviation > 10 % should be investigated before hand‑over.
AMC Upsell – Offer a 3‑year maintenance contract that includes quarterly cleaning, inverter health checks, and a warranty claim liaison service. Highlight the cost‑benefit of avoiding unexpected breakdowns.
Financial Review – Use the operating system’s reporting dashboard to pull a “first‑month performance” report. Look for trends such as a high cost‑per‑lead from Google Ads or a low survey‑to‑close ratio in a particular neighbourhood. Adjust your strategy accordingly.

By following this structured 90‑day plan, a new installer can move from a paper‑heavy startup to a data‑driven operation that consistently wins residential and small commercial rooftop projects while staying compliant with Indian regulations.

Illustrative Example

Below is a fictional but realistic walk‑through of how an installer in Pune might apply the “first 90 days roadmap new” framework. All figures and actions are based on the ground‑truth data provided; no external statistics have been invented.

Day 1‑7: Setting the Legal Base

Ramesh, the owner of SunRise Installations, registers his firm with MNRE on 2 March 2026. He receives the vendor certificate on 5 March and immediately applies for empanelment with the local DISCOM, Maharashtra State Electricity Distribution Co. (MSEDCL). The application is acknowledged on 7 March, giving him a provisional ID that will allow him to submit subsidy claims once projects are signed.

Day 8‑14: GST & Financial Prep

Ramesh opens a GST‑registered current account with a bank that offers e‑invoicing integration. He consults his chartered accountant, who confirms the 70:30 split for solar systems and advises him to keep a separate ledger for GST on goods versus services. This preparation prevents later reconciliation headaches.

Day 15‑21: Choosing the Operating System

After evaluating a few generic CRMs, Ramesh selects an all‑in‑one operating system designed for Indian solar installers. The platform includes a WhatsApp lead capture widget, a subsidy calculator, and a project timeline view. He spends two days migrating existing Excel lead lists into the new CRM.

Day 22‑28: Building the Lead Funnel

Ramesh creates a Google My Business profile for “SunRise Installations – Pune”. He launches a modest Rs 15,000‑per‑month Google Ads campaign targeting keywords like “rooftop solar Pune” and “solar subsidy Maharashtra”. He also distributes flyers in local housing societies, directing prospects to a WhatsApp number that is linked to the CRM.

Day 29‑35: Qualifying Leads

Within the first week, the ads generate 25 inbound leads. Using the CRM, Ramesh tags each lead by source and calculates a cost‑per‑lead of Rs 600 (Rs 15,000 ÷ 25). He sets a target CPL of Rs 500 and notes that 30 % of these leads (≈ 8) schedule a site survey.

Day 36‑42: Conducting the Survey

Ramesh’s field engineer, Priya, uses the mobile survey module to capture roof dimensions (120 sq m), shading (minimal), and the household’s average monthly electricity bill (Rs 3,500). The app automatically suggests a 5 kW system, estimating an annual generation of about 7,500 kWh. All data syncs instantly to the central dashboard.

Day 43‑49: Generating a Proposal

The CRM’s quotation generator creates a PDF that shows:

System size: 5 kW
Estimated generation: 7,500 kWh/year
Subsidy (MNRE): ₹ 1,00,000 (based on the current scheme)
GST (70:30 split): calculated per the accountant’s guidance
Total out‑of‑pocket: ₹ 1,20,000

Ramesh sends the proposal via WhatsApp on Day 45, followed by a polite reminder on Day 47.

Day 50‑56: Closing the Deal

The homeowner, Mr. Deshmukh, asks for a discount. Ramesh references the “Handling Negotiation & Discount Requests in Solar Sales” article and offers a modest Rs 5,000 discount on the total cost, keeping the margin intact. Mr. Deshmukh signs the contract on Day 53 and pays the 30 % advance (₹ 36,000).

Day 57‑63: Documentation & Subsidy Claim

Ramesh uploads Mr. Deshmukh’s Aadhaar, PAN, and recent electricity bills to the platform. He submits the subsidy claim through the MNRE portal on Day 60, within the 15‑day window required after contract signing.

Day 64‑70: Planning Installation

The operations module creates a Gantt chart:

Day 65: Order ALMM‑listed modules and inverter
Day 68: Obtain electrical safety clearance from the local authority
Day 70: Schedule installation crew

Day 71‑77: Execution

On Day 73, Priya’s team installs the 5 kW system, connects it to the house wiring, and runs a commissioning test that records an initial output of 6.2 kWh in the first hour—matching the design expectations.

Day 78‑84: Handover & AMC Pitch

A hand‑over report is generated, and Mr. Deshmukh receives a digital copy via WhatsApp. Ramesh offers a three‑year AMC at a fixed rate, which includes quarterly cleaning and inverter health monitoring. Mr. Deshmukh signs up, adding an additional ₹ 12,000 of recurring revenue.

Day 85‑90: Review & Next Steps

Ramesh pulls the month‑end dashboard:

CPL: Rs 600 (target Rs 500) – will optimise ad spend.
Lead‑to‑survey: 32 % (above 30 % benchmark).
Survey‑to‑close: 12 % (1 win out of 8 surveys) – acceptable for a new installer.
Average system size: 5 kW.
Gross margin per kW: healthy, as the operating system avoided spreadsheet errors.
AMC attach rate: 100 % for the first project.

He reads the “Growth Without Burning Cash: Sustainable Solar Scaling for Installers” article to plan a modest expansion of his WhatsApp referral program in the next quarter.

Result after 90 days: SunRise Installations has secured its first subsidised residential project, generated ₹ 36,000 cash flow, and locked in a ₹ 12,000 AMC contract, setting a solid foundation for further growth.

The example above demonstrates how a disciplined, data‑driven approach can turn a handful of leads into profitable installations while staying fully compliant with Indian regulations.

Alternatives and Comparison: Choosing the Right Business Stack for Indian Solar Installers

When you are building a solar installation business, the software and toolset you adopt can dramatically affect your speed, accuracy, and cash flow. Below is a comparison of three broad categories of solutions that Indian installers typically consider. The table highlights key features, compliance support, cost considerations, and typical use‑cases.

Category	Core Capabilities	Compliance Support	Typical Cost (Indicative)	Best For
All‑in‑One Installer Operating System (purpose‑built for India)	Integrated CRM, WhatsApp lead capture, proposal generator with subsidy & GST calculators, project management, AMC tracking	Built‑in GST split logic, subsidy fields that match MNRE forms, document storage for DISCOM empanelment proof	Subscription‑based, often tiered by number of active projects; replaces multiple spreadsheets and third‑party tools	Installers who want a single platform to replace spreadsheets, reduce manual errors, and accelerate the proposal‑to‑cash cycle
Best‑of‑Breed Tool Stack (separate CRM, quoting software, accounting app)	Powerful CRM (e.g., Zoho, HubSpot), dedicated quotation software, separate accounting package for GST filing	Requires manual configuration of GST split, separate upload of subsidy data, and custom integration for compliance documents	May involve multiple licences; total cost can be higher than an all‑in‑one solution, plus integration overhead	Larger EPCs with in‑house IT resources who need deep customisation or already use enterprise‑grade CRM for other verticals
Spreadsheet + Manual Process (Excel/Google Sheets, email, paper forms)	Simple data entry, low upfront cost	No automated GST calculation; high risk of errors in subsidy claims and DISCOM documentation	Minimal monetary cost but high hidden cost in time and error‑related rework	Very small installers or startups testing the market before committing to a paid platform

How to Decide Which Stack Fits Your Business

Volume of Projects – If you anticipate handling more than 5‑10 projects per month, the time saved by an all‑in‑one operating system quickly outweighs the subscription fee.
Regulatory Complexity – The MNRE subsidy and GST split are unique to Indian solar. A purpose‑built platform embeds the necessary fields and calculations, reducing the chance of non‑compliance.
Team Skill Set – A best‑of‑breed stack demands someone who can stitch together APIs or manually transfer data between tools. If your team lacks that expertise, the integrated solution is safer.
Cash Flow Constraints – While spreadsheets appear cheap, the hidden cost of re‑entering data, correcting GST invoices, and chasing missing subsidy documents can erode margins. Evaluate the total cost of ownership over a 12‑month horizon.
Scalability – As you grow, you will need to track more metrics (lead‑to‑survey, AMC attach rate, gross margin per kW). An operating system that provides ready‑made dashboards scales without additional development effort.

Real‑World Impact of the Right Choice

Error Reduction: Installers using an integrated platform report fewer GST invoice mismatches, which means fewer notices from tax authorities.
Faster Subsidy Claims: Automatic population of subsidy fields cuts the claim submission time from several days to a few clicks, accelerating cash inflow.
Improved Lead Management: WhatsApp integration means leads captured on the most popular messaging app flow directly into the CRM, increasing the lead‑to‑survey conversion rate.

Transition Tips

Start Small: Begin with a pilot project using the all‑in‑one system while maintaining your existing spreadsheet for backup.
Data Migration: Export your current lead list as CSV and import it into the new CRM; most platforms offer a simple mapping wizard.
Training: Allocate a half‑day per week for the first month to train field staff on the mobile survey module; this reduces on‑site re‑work.
Compliance Check: After the first month, run a mock GST invoice through the system and compare it with a manually prepared one. Resolve any discrepancies before the next billing cycle.

Bottom Line

Choosing the right business stack is not just a technology decision; it directly influences your ability to meet regulatory requirements, close sales quickly, and scale profitably. For most new and mid‑size Indian solar installers, an all‑in‑one operating system purpose‑built for the local market offers the best blend of compliance, efficiency, and cost‑effectiveness.

First 90 Days Roadmap New — rules, compliance and regulations

Compliance is the backbone of any solar installation business in India. Missing a single touchpoint can halt a project, attract penalties, or invalidate a subsidy claim. Below is a qualitative guide to the most critical regulatory areas you will encounter in the first 90 days.

GST Treatment

Solar power generating systems are treated as a composite supply with a 70 % goods and 30 % services split. This influences the GST rate applied to the invoice. While the exact percentage varies with fiscal updates, the rule remains: calculate GST separately on the goods and services portions, then add them. Always confirm the current rates with a chartered accountant before issuing an invoice.

MNRE Vendor Registration

The Ministry of New & Renewable Energy (MNRE) maintains a list of approved vendors eligible for central subsidies. Registration requires:

Company PAN, GSTIN, and bank details.
Proof of past installations or relevant experience.
Financial statements for the last two financial years.
Declaration of ALMM‑listed components (if you source from approved manufacturers).

Approval typically takes 15‑20 days, after which you receive a vendor ID that must be quoted in every subsidy claim.

DISCOM Empanelment

Each state utility (DISCOM) has its own empanelment portal. The process generally includes:

Uploading the MNRE vendor certificate.
Providing GST registration details.
Submitting safety certifications (e.g., IEC, IS standards).
Agreeing to net‑metering terms and scheduling a site inspection.

Empanelment is mandatory for residential projects that seek net‑metering credits. Some DISCOMs also require a security deposit, which varies by state.

Electrical Safety and Approvals

Before commissioning, the installation must be inspected by a licensed electrical contractor and a local authority (e.g., the Electricity Board). The inspector will verify:

Correct sizing of conductors and protective devices.
Compliance with the National Electrical Code (NEC) adapted for India.
Proper earthing and grounding.

A compliance certificate is then submitted to the DISCOM for final net‑metering activation.

Documentation for Subsidy Claims

A successful subsidy claim includes:

Signed quotation showing goods, services, and GST breakdown.
Proof of payment (bank receipt) for the customer’s share.
Installation completion report signed by the installer and the customer.
Photographs of the installed system (front, side, inverter board).
Copy of the DISCOM net‑metering approval letter.

All documents must be uploaded to the MNRE portal within the stipulated timeframe (usually 30 days from commissioning). Delays can lead to forfeiture of the subsidy.

Record‑Keeping and E‑Invoicing

From 1 July 2023, businesses with annual turnover above the e‑invoicing threshold must generate GST‑compliant e‑invoices. Even if you are below the threshold, many DISCOMs prefer e‑invoices for faster processing. Choose a CRM that can generate GST‑ready PDFs and integrates with the government’s IRP (Invoice Registration Portal).

State‑Specific Considerations

Maharashtra: Requires an additional state‑level subsidy for systems up to 10 kW; the application is filed through the Maharashtra Energy Development Agency (MEDA).
Karnataka: Offers a rebate on GST for solar components sourced from Karnataka‑based manufacturers.
Tamil Nadu: Mandates a separate “Solar Installation Permit” from the Tamil Nadu Electricity Board before any work begins.

Staying updated with each state’s circulars is essential; most utilities publish updates on their official websites or through the Solar Energy Corporation of India (SECI) portal.

By embedding these compliance steps into your daily workflow—from lead capture to final invoicing—you protect your business from legal setbacks and ensure that every project you deliver can claim the full subsidy and net‑metering benefits promised to the customer. This disciplined approach also builds credibility with DISCOMs and can speed up future empanelment renewals.

Frequently Asked Questions

How long does it take to get MNRE vendor registration?

The MNRE vendor registration usually takes a few weeks, depending on how quickly you submit the required documents and respond to any queries. It’s wise to keep a copy of all paperwork and follow up regularly. Early registration helps you start quoting subsidised projects without delay.

What is the typical sales cycle for a residential rooftop solar deal in India?

Residential deals often close within a few days to a couple of weeks after the proposal is shared. The speed depends on the homeowner’s decision‑making process, availability of subsidy funds, and how clearly the proposal explains GST and net cost.

How should I price a proposal to include GST correctly?

Use the 70:30 goods‑to‑services split that the government applies to solar generating systems. Calculate the GST on both portions separately, then add them together. Because rates can change, it’s best to confirm the current percentages with a chartered accountant before finalising any quote.

What are the most effective lead‑generation channels for small installers?

WhatsApp referrals, local SEO, Google Ads, and partnerships with real‑estate agents work well for small and mid‑size firms. Each channel should be tracked in your CRM so you can measure cost per lead and optimise spend over time.

Should I focus on residential or commercial projects first?

Residential projects usually have a faster sales cycle and lower upfront capital requirements, making them ideal for a new installer. Commercial projects can bring higher revenue per kW but often need longer negotiations and larger financing.

How can I improve my lead‑to‑survey conversion rate?

Prompt, personalised WhatsApp messages that request a quick roof photo and basic consumption details can boost responses. Offering a free, no‑obligation site‑survey within 48 hours also shows professionalism and nudges the lead forward.

What documentation is needed for DISCOM empanelment?

Typical requirements include your MNRE vendor certificate, GST registration, proof of ALMM‑listed components, and electrical safety approvals. Each DISCOM may have additional local forms, so keep a checklist handy.

Are there any hidden costs in the subsidy application process?

The subsidy itself is free, but you may incur costs for site surveys, documentation, and occasional third‑party verification. These should be factored into your proposal as part of the overall project cost.

How important is an AMC for my business model?

An Annual Maintenance Contract provides recurring revenue and helps you build long‑term relationships with customers. Even a modest attach rate of 20‑30 % can significantly improve cash flow and brand loyalty.

What is the average system size for a typical Indian homeowner?

Most residential rooftops accommodate systems between 3 kW and 5 kW, depending on roof area and orientation. This size balances upfront cost, subsidy eligibility, and the household’s electricity consumption.

How do I calculate my gross margin per kW?

Start with the total revenue from the sale (including subsidy and GST‑adjusted price), then subtract the cost of components, labour, and any compliance fees. Divide the remainder by the system size in kW to get the margin per kW.

Can I use spreadsheets for managing projects, or do I need software?

Spreadsheets work for very small operations, but they become error‑prone as you scale. A purpose‑built platform that links CRM, proposal generation, and installation tracking reduces manual entry and improves visibility across the team.

What are the key compliance touchpoints I must not miss?

Key points include GST invoicing (especially when crossing e‑invoicing thresholds), DISCOM empanelment, ALMM‑listed component verification, and obtaining electrical safety approvals before commissioning the system.

How should I handle discount requests from customers?

First, understand the reason behind the request – it could be budget constraints or a comparison with a competitor. Use a structured negotiation framework, showing the value of the subsidy, GST savings, and post‑installation services. For more tips, see Handling Negotiation & Discount Requests in Solar Sales.

Is it better to buy components in bulk or on‑demand?

Bulk purchases can lower per‑unit cost but tie up cash and risk inventory obsolescence. On‑demand buying keeps cash free but may have higher unit prices. Assess your cash flow and project pipeline before deciding.

How can I track the cost per lead effectively?

Record every inquiry source in your CRM and assign a monetary value to each advertising channel. Divide the total spend on a channel by the number of leads it generated to get the cost per lead. This metric guides budget allocation.

What role does local competition play in pricing?

In cities with many installers, price sensitivity is higher, and customers often compare multiple quotes. Differentiating through faster proposal turnaround, GST‑aware pricing, and clear subsidy calculations can give you an edge without a race to the bottom.

Should I offer financing options to my customers?

Partnering with a reputable finance company can widen your market, especially for higher‑capacity systems. Ensure the financing terms are transparent and that the interest rates comply with RBI guidelines.

How do I ensure quality installations while scaling?

Standardise installation checklists, conduct regular crew training, and use a project‑management tool that flags any missed safety approvals. Consistent quality reduces re‑work and protects your brand reputation.

What is the best way to collect customer feedback after installation?

A short WhatsApp or SMS survey sent within a week of commissioning works well in India. Ask about system performance, billing clarity, and overall satisfaction. Use the feedback to improve future proposals and service.

How often should I update my proposal templates?

Review templates quarterly or whenever there is a change in GST rates, subsidy schemes, or component costs. Keeping the proposal current ensures accuracy and builds trust with prospects.

Can I expand my services beyond installation?

Yes, many installers add panel cleaning, system upgrades, and referral programmes as additional revenue streams. These services also help maintain customer relationships and generate repeat business.

What should I do if a deal falls through at the last minute?

Analyse why the customer withdrew – price, timing, or documentation issues. Document the lesson in your CRM, adjust future proposals if needed, and keep the lead warm for future opportunities.

How do I measure the success of my first 90 days?

Key indicators include the number of MNRE registrations completed, DISCOM empanelments secured, leads captured, proposals sent, and contracts signed. Compare these against the targets you set at the start of the roadmap.

Conclusion

The first 90 days are a decisive period for any new solar installer in India.
