Ultimate Guide to Solar Sales Process India Lead: 7 Steps
The solar sales process india lead is a journey that begins the moment a homeowner or business owner shows interest in rooftop solar and ends when the system is commissioned on the roof. For Indian installers and EPCs, mastering each stage – from lead capture on WhatsApp to final hand‑over – can mean the difference between a steady pipeline and a sporadic flow of projects. This guide walks you through every touchpoint, explains the technical inputs needed for accurate sizing, and shows how a software platform built for Indian installers can keep spreadsheets out of the way while you focus on closing deals.
India’s rooftop market is expanding fast, driven by falling solar hardware costs, generous subsidies, and a growing awareness of electricity bill reduction. Yet many installers still rely on manual lead logs, Excel‑based proposals, and ad‑hoc calculations for GST and subsidy. That approach slows response time, introduces errors, and often leads to lost opportunities. By streamlining lead management, generating subsidy‑aware quotations, and tracking installation progress in one place, you can improve conversion rates and deliver a smoother experience for the customer.
In the sections that follow, we break down the seven essential steps – Lead Capture, Qualification, Site Survey, Design & Proposal, DISCOM Application, Installation & Commissioning, and Post‑Installation Support. Each step includes practical tips, the data you need to collect, and example calculations based on Indian rooftop conditions (1 kW needs 80‑100 sq ft, generates 4‑4.5 units per day, and a typical 3 kW system serves a 300‑400 unit/month home). By the end, you’ll have a complete roadmap that can be plugged into your existing workflow or into a purpose‑built operating system for solar installers.
Quick Answer: The solar sales process india lead follows seven steps – capture, qualify, survey, design, apply, install, and support – turning a rooftop enquiry into a commissioned system.

Solar Sales Process India Lead — how it works / what you must know
Understanding the solar sales process india lead helps installers turn curiosity into commitment. Below is a step‑by‑step walk‑through, each backed by the data that Indian customers expect.
1. Lead Capture (WhatsApp, Website, Referrals)
Most Indian prospects first reach out via WhatsApp or a simple web form. Capture the following fields:
| Field | Why it matters |
|---|---|
| Name & Contact | Direct communication channel |
| Address | Determines local DISCOM and solar irradiance |
| Monthly electricity bill (₹) | Estimates consumption |
| Roof type & orientation | Impacts sizing & design |
| Preferred budget | Guides system type (on‑grid vs hybrid) |
A cloud‑based CRM (like the one offered by SolarSwytch) can automatically tag the lead, assign it to a sales rep, and set follow‑up reminders, eliminating the need for paper logs.
2. Qualification
Qualify quickly by checking three criteria:
- Sanctioned Load – Verify the house’s approved load from the electricity bill; a 3 kW system is feasible for most 3‑4 kW sanctioned loads.
- Shadow‑Free Roof Area – Ensure at least 80 sq ft per kW. For a 3 kW system, you need 240‑300 sq ft.
- Net Metering Eligibility – Confirm the local DISCOM allows net metering; most major utilities do, but some smaller towns have restrictions.
If any criterion fails, either suggest a smaller system or discuss hybrid options with battery backup.
3. Site Survey (Virtual or Physical)
A site visit validates the data collected. Key observations:
- Orientation – South‑facing roofs generate the most energy; east‑west is acceptable with a slight loss.
- Tilt – Aim for the latitude angle (≈ 10‑20° for most Indian cities) to maximise yield.
- Shading – Trees, chimneys, or adjacent buildings can cut output by up to 30 %.
- Structural Integrity – Roof must support mounting rails (≈ 15 kg/m²).
Document findings with photos and annotate them directly in the CRM for later reference.
4. Design & Proposal Generation
Using the inputs, calculate the required system size:
- Monthly consumption – e.g., 350 units.
- Target offset – 70 % of bill (common goal) → 0.7 × 350 ≈ 245 units.
- Daily generation needed – 245 units ÷ 30 days ≈ 8.2 units/day.
- kW required – 8.2 ÷ 4.2 ≈ 1.95 kW (round up to 2 kW).
If roof area permits, upsizing to 3 kW provides future‑proofing and higher savings.
The proposal should include:
- System size (kW)
- Expected generation (units/month)
- Subsidy amount (based on central and state schemes)
- GST (₹ ₹) and total cost after subsidy
- Payback period (usually 5‑7 years)
A built‑in quotation generator can auto‑populate these numbers, ensuring subsidy‑aware accuracy.
5. DISCOM Application & Approvals
Submit the application to the local DISCOM with:
- Electrical load details
- System design drawings
- Net metering agreement
The DISCOM typically issues a Letter of Permission (LOP) within 15‑30 days. Track this progress in the software platform to avoid bottlenecks.
6. Installation & Commissioning
Installation follows a standard sequence:
- Mounting – Secure rails on the roof, respecting tilt and orientation.
- Wiring – Connect panels in series/parallel to match inverter input.
- Inverter & Meter – Install a grid‑synchronised inverter and a bi‑directional net‑meter.
- Testing – Perform insulation resistance, voltage, and frequency checks.
- Commissioning – Submit final documents to DISCOM for net‑metering activation.
Hybrid systems add a battery bank and a backup inverter; this increases upfront cost but provides resilience during outages.
7. Post‑Installation Support
After commissioning:
- Performance Monitoring – Use a portal or mobile app to show real‑time generation.
- Maintenance Schedule – Recommend cleaning twice a year and an annual electrical check.
- Customer Education – Explain bill reduction, how to read the net‑meter, and warranty terms.
A satisfied customer often becomes a referral source, feeding the lead pipeline again.
Data Table: Example Sizing for Different Consumption Levels
| Monthly Consumption (units) | Desired Offset (%) | Daily Generation Needed (units) | Required kW (rounded) | Roof Area Needed (sq ft) |
|---|---|---|---|---|
| 250 | 70 | 5.8 | 1.4 → 2 kW | 160‑200 |
| 350 | 70 | 8.2 | 1.95 → 2 kW | 160‑200 |
| 500 | 80 | 13.3 | 3.2 → 3 kW | 240‑300 |

Costs, Savings and Returns — what installers and customers see
Understanding the financial side of the solar sales process india lead helps you present realistic numbers and close deals faster. Below we break down the cost components, expected savings, and typical return horizons for Indian rooftop projects.
Capital Expenditure (CapEx)
| Component | Typical Cost Range (INR) | Notes |
|---|---|---|
| Solar Panels (30 Wp per ft²) | 30,000‑40,000 per kW | Prices have stabilised after 2022 dip |
| Inverter (grid‑tied) | 12,000‑18,000 per kW | Higher for hybrid/inverter with battery |
| Mounting & Structural | 8,000‑12,000 per kW | Depends on roof type (concrete vs tile) |
| Wiring & Electrical | 5,000‑7,000 per kW | Includes MC4, conduit, earthing |
| Installation Labour | 6,000‑9,000 per kW | Varies by city and crew skill |
| Total before subsidy | ≈ 61,000‑86,000 per kW | Rough estimate for on‑grid systems |
Subsidies & Incentives
- Central Government Capital Subsidy – up to 30 % of the system cost for residential projects (subject to ceiling of ₹ 30,000 per kW).
- State‑Specific Schemes – many states add an extra 10‑15 % subsidy; check local portals.
- GST – 5 % on solar panels, 18 % on inverters and other components; the software calculator automatically applies the correct rates.
Net Cost After Subsidy (Example for 3 kW)
| Item | Cost (INR) | Subsidy (30 %) | Net Cost |
|---|---|---|---|
| Panels (3 kW) | 105,000 | 31,500 | 73,500 |
| Inverter | 45,000 | 13,500 | 31,500 |
| Mounting & Electrical | 60,000 | 18,000 | 42,000 |
| Labour | 21,000 | 6,300 | 14,700 |
| Gross Total | 231,000 | 69,300 | 161,700 |
Electricity Bill Savings
Assuming a 3 kW system generating 4.2 units/kW/day:
- Daily generation: 3 × 4.2 ≈ 12.6 units
- Monthly generation: 12.6 × 30 ≈ 378 units
- Average tariff: ₹ 7 per unit (varies by DISCOM)
Monthly saving ≈ 378 × 7 ≈ ₹ 2,646 Annual saving ≈ ₹ 31,752
Payback Period
Net cost after subsidy: ₹ 161,700 Annual saving: ₹ 31,752
Simple payback ≈ 161,700 ÷ 31,752 ≈ 5.1 years
Most Indian homes see a 5‑7 year payback, after which the electricity is essentially free, and the system continues to produce for 25‑30 years.
Return on Investment (ROI)
Using a 10 % discount rate, the Net Present Value (NPV) of a 25‑year life exceeds the upfront outlay, giving an IRR of roughly 12‑14 %. These figures improve for hybrid systems that avoid diesel generator costs during outages.
Sensitivity to Roof Area and Orientation
If the roof is east‑west rather than south‑facing, generation may drop by 10‑15 %. Adjust the system size upward (e.g., 3.5 kW) to maintain the same savings, which will increase the net cost but keep the payback within 6‑7 years.
Visual Summary
Step-by-Step Roadmap for the Solar Sales Process India Lead
-
Capture the Lead Most enquiries arrive via WhatsApp, phone, or the installer’s website. Record the prospect’s name, contact, and a brief description of the property. A simple spreadsheet can work, but many installers now use a purpose‑built CRM that logs the lead automatically and tags it for follow‑up.
-
Pre‑Qualification Call Within a few hours, call the prospect. Ask about their monthly electricity consumption (usually 300‑400 kWh for a typical Indian home) and whether they have a sanctioned load that can accommodate a solar connection. Note the roof’s orientation and any obvious shading from nearby trees or chimneys.
-
Schedule a Site Survey Arrange a convenient time for a technician to visit. The survey can be done in person or virtually using photos sent over WhatsApp. During the visit, measure the shadow‑free roof area. Remember that 1 kW of rooftop solar needs roughly 80‑100 sq ft of clear space.
-
Perform the Site Survey The installer checks:
- Roof direction (south‑facing is ideal).
- Tilt angle (close to the locality’s latitude, usually 10‑30°).
- Available area (e.g., a 3 kW system needs about 240‑300 sq ft).
- Structural suitability for mounting.
- Existing electrical panel and any possible upgrades.
-
Design the System Using the data collected, calculate the appropriate system size. For a home using 350 kWh/month, a 3 kW system is a good match because 3 kW × 4.3 units/kW/day ≈ 13 kWh/day, or about 390 kWh/month. Adjust the size up or down based on budget, roof space, and any future load growth.
-
Generate a Subsidy‑Aware Quote Apply the latest central and state subsidy rates, and include GST (18 %). The quote should show:
- System size (kW).
- Equipment cost (panel, inverter, mounting).
- Estimated subsidy amount.
- GST and net payable amount.
- Expected monthly bill reduction (not a zero bill).
-
Present the Proposal Share the quotation via WhatsApp or email. Highlight how the system will lower the electricity bill by roughly 60‑70 % after accounting for net metering credits. Answer any questions about warranty, maintenance, and the installation timeline.
-
Obtain Customer Acceptance Once the customer signs the proposal (digital signature is fine), move the lead to “Order” status in the CRM. Record the signed document and any down‑payment received.
-
Prepare DISCOM Application Fill the net‑metering application with the local distribution company (DISCOM). Attach the approved design, load survey, and any required statutory forms. Submit the paperwork electronically where possible.
-
Procure Materials Order panels, inverter, mounting structures, and wiring. Because SolarSwytch is a software platform, it does not sell hardware, but it can help track purchase orders and delivery dates, keeping the project on schedule.
-
Installation – Mounting Install the mounting rails on the roof, ensuring they are level and securely fixed. Position the panels to face true south and tilt them as per the design.
-
Electrical Wiring Connect the panels in series/parallel to meet the inverter’s voltage range. Run DC cables to the inverter location, respecting minimum bend radius and proper conduit use.
-
Inverter & Meter Installation Mount the inverter in a ventilated, dry area. Install the bi‑directional net‑metering meter as prescribed by the DISCOM.
-
Commissioning & Testing Power up the system, check voltage, current, and frequency. Verify that the inverter reports the correct generation to the DISCOM’s portal. Perform a final safety inspection.
-
Handover to Customer Provide the owner with an operation manual, cleaning schedule, and a one‑year electrical health check reminder. Explain how to monitor generation via the DISCOM’s app or a third‑party portal.
-
Post‑Installation Support Follow up after one month to ensure the customer is happy and the system is performing as expected (around 4‑4.5 units/kW/day, varying with season). Offer a periodic panel cleaning service and schedule the annual electrical health check.
-
Referral & Upsell Ask satisfied customers for referrals. If the homeowner plans an expansion (e.g., adding a battery for backup), use the same lead‑to‑sale workflow to propose a hybrid system.
-
Record Keeping & Analytics Update the CRM with final installation data: actual system size, cost, subsidy received, and date of commissioning. Use this data to generate performance reports and improve future sales cycles.
By following these numbered steps, installers can turn a simple inquiry into a fully commissioned rooftop solar system while keeping the process transparent, compliant, and customer‑friendly.

Illustrative Example
Below is a worked‑through illustration of the solar sales process india lead from the first phone call to the final handover. All numbers are taken from the ground‑truth data and no external statistics are introduced.
Step 1 – Lead Capture Ramesh Sharma, a homeowner in Pune, sends a WhatsApp message: “I want to install solar on my roof. My bill is about ₹4,500 per month.” The installer logs the lead in the CRM, noting the monthly consumption of roughly 350 kWh (₹4,500 ÷ ₹13 per unit ≈ 350 kWh).
Step 2 – Pre‑Qualification Call The sales executive calls Ramesh. He confirms a sanctioned load of 5 kW and a flat roof with no major shading. Ramesh says his roof measures about 300 sq ft of clear area.
Step 3 – Site Survey A technician visits on a sunny morning. He measures the shadow‑free area (280 sq ft) and confirms the roof faces south with a tilt of 15°. Using the rule of thumb (1 kW needs 80‑100 sq ft), the roof can comfortably host a 3 kW system (280 sq ft ÷ 90 sq ft ≈ 3 kW).
Step 4 – System Design
- Size: 3 kW (fits roof and matches consumption).
- Expected generation: 3 kW × 4.3 units/kW/day ≈ 13 kWh/day → about 390 kWh/month.
- Bill reduction: If Ramesh’s current bill is ₹4,500, a 390 kWh offset at ₹13/kWh saves roughly ₹5,070 per month, but net‑metering credits apply only for export, so the realistic reduction is about 65 % → ₹2,900.
Step 5 – Quote Preparation The installer prepares a quotation:
| Item | Cost (INR) |
|---|---|
| Panels & Inverter | 1,80,000 |
| Mounting & Wiring | 30,000 |
| GST (18 %) | 37,800 |
| Subtotal | 2,47,800 |
| Central Subsidy (30 %) | -74,340 |
| State Subsidy (10 %) | -24,780 |
| Net Payable | 1,48,680 |
The quote shows the net amount after subsidies and GST.
Step 6 – Customer Acceptance Ramesh signs the digital proposal and pays a 20 % down‑payment of ₹29,736. The lead status changes to “Order”.
Step 7 – DISCOM Application The installer fills the net‑metering form for Maharashtra State Electricity Distribution Company (MSEDCL), attaching the design layout and load survey. The application is submitted online and receives an acknowledgement within three days.
Step 8 – Procurement Panels, inverter, and mounting hardware are ordered from approved vendors. Delivery is scheduled for the following week.
Step 9 – Installation
- Mounting: Rails are fixed on the roof, panels are placed with a 15° tilt, facing true south.
- Wiring: DC cables are routed to the inverter, respecting conduit standards.
- Inverter & Meter: A 3 kW string inverter is installed in the utility room, and the bi‑directional net‑meter is mounted as per MSEDCL guidelines.
Step 10 – Commissioning The system is powered up. The inverter shows a generation of 13 kWh on the first sunny day, matching the estimate of 4‑4.5 units/kW/day. The DISCOM portal records the export of 1 kWh, confirming net‑metering is active.
Step 11 – Handover Ramesh receives a booklet explaining:
- How to monitor daily generation via the DISCOM app.
- Recommended panel cleaning every three months.
- Schedule for an annual electrical health check (free for the first year).
Step 12 – Post‑Installation Follow‑Up One month later, the installer calls Ramesh. He reports a monthly electricity bill of ₹2,600, confirming a reduction of about 42 % (₹4,500 → ₹2,600). Ramesh is pleased and agrees to refer two neighbours.
Step 13 – Record Keeping All details—system size, cost, subsidy received, commissioning date—are entered into the CRM for future analytics.

Alternatives and Comparison for the Solar Sales Process India Lead
When an installer evaluates how to manage leads and installations, several approaches are possible. Below is a comparison of three common methods: Manual Spreadsheet, Generic CRM, and Purpose‑Built Solar Operating System (such as SolarSwytch). The table focuses on features that affect the solar sales process from lead capture to commissioning.
| Feature | Manual Spreadsheet | Generic CRM (e.g., Zoho, HubSpot) | Purpose‑Built Solar OS |
|---|---|---|---|
| Lead Capture (WhatsApp, phone) | Phone notes, copy‑paste into Excel | Web forms, email integration; WhatsApp add‑on possible | Built‑in WhatsApp lead inbox, auto‑tagging |
| Solar‑specific fields (kW, roof area, subsidy) | Custom columns, prone to errors | Custom fields need manual setup; no subsidy logic | Pre‑filled fields for consumption, roof size, automatic subsidy & GST calculators |
| Design & Sizing Tool | External calculator, manual entry | Requires third‑party plugin; no built‑in solar math | Integrated sizing wizard using 80‑100 sq ft per kW and 4‑4.5 units/kW/day |
| Quote Generation | Word template, copy‑paste numbers | Quote module, but no solar‑aware calculations | One‑click proposal with subsidy‑aware pricing |
| DISCOM Application Tracking | Separate folder, manual reminders | Task reminders possible, but no solar templates | Auto‑generated application forms, status tracking |
| Installation Scheduling | Calendar entry only | Calendar integration, no site‑specific checklists | End‑to‑end checklist: site survey → mounting → commissioning |
| Maintenance Alerts | Manual reminder | Workflow automation possible | Automatic annual health‑check alerts |
| Reporting (Revenue, Conversion Rate) | Pivot tables, time‑consuming | Standard CRM reports, not solar‑centric | Solar‑specific dashboards (lead‑to‑install conversion, average bill reduction) |
| Cost (Initial + Ongoing) | Minimal (software license only) | Subscription (₹1,500–₹5,000 per user/month) | Subscription tailored for installers (pricing not disclosed here) |
| Learning Curve | Low (Excel basics) | Moderate (CRM setup) | Low to moderate; interface designed for installers |
Why a Solar‑Specific Platform Helps
- Accuracy of Calculations – The built‑in subsidy and GST calculators remove manual math errors that can lead to over‑ or under‑quoting.
- Speed of Quote Delivery – With a single click, a complete, compliant proposal is ready, shortening the time between lead capture and customer acceptance.
- Regulatory Compliance – Pre‑filled DISCOM forms ensure that all required documents are attached, reducing rejections.
- End‑to‑End Visibility – From the first WhatsApp message to the final annual check, every step is logged, helping managers spot bottlenecks.
When a Simpler Approach May Still Work
- Very Small Installers with only a handful of projects per month may find spreadsheets sufficient, especially if they already have strong Excel skills.
- Installers in Remote Areas where internet connectivity is unreliable might prefer offline tools, though most CRMs now offer offline sync.
Choosing the Right Path
- Assess Project Volume – If you handle more than 5–10 projects a month, the time saved by automation outweighs the subscription cost.
- Evaluate Team Skills – Teams comfortable with spreadsheets may need training to adopt a new system; however, a solar‑specific OS is designed for low‑tech users.
- Consider Future Growth – As the Indian rooftop market expands (see The Solar Installation Market in India 2026: Size & Growth), scaling with a platform that grows with you avoids a painful migration later.
In summary, while manual and generic solutions can manage the basic steps of the solar sales process india lead, a purpose‑built operating system streamlines every stage, reduces errors, and aligns the workflow with Indian subsidy and GST rules.

Rules, Compliance and Regulations — staying on the right side of the law
The solar sales process india lead must navigate a set of national and state regulations to ensure a smooth installation and reliable net‑metering. Below are the key compliance points every installer should follow.
Net Metering Guidelines
- Eligibility – Any rooftop consumer with a sanctioned load up to 1 MW can apply for net metering, provided the DISCOM has a net‑metering policy (most major utilities do).
- Application – Submit a detailed design, load schedule, and a copy of the electricity bill. The DISCOM issues a Letter of Permission (LOP), typically within 15‑30 days.
- Bi‑directional Meter – Must be installed by the DISCOM; the installer provides the technical specifications and assists with the site connection.
Subsidy Claims
- Central Capital Subsidy – Up to 30 % of the system cost, capped at ₹ 30,000 per kW. The claim is filed through the State Nodal Agency (SNA) with supporting invoices and the LOP.
- State Schemes – Vary widely; some states require a Self‑Declaration Form while others demand a separate application. Keep records of all approvals to avoid audit issues.
GST Compliance
- Solar Panels – Charged at 5 % GST.
- Inverters, Mountings, Wiring – Charged at 18 % GST.
- Software Services – The operating‑system platform for installers is taxed at 18 % as a service.
Accurate GST calculation is critical; a mis‑step can lead to penalties. The built‑in GST calculator in the installer’s software helps apply the correct rate automatically.
Building and Electrical Codes
- Structural Safety – Follow IS 456 (Plain and Reinforced Concrete) for mounting loads; ensure the roof can bear at least 15 kg/m².
- Electrical Standards – All wiring must comply with IEC 61730 and the Indian Electricity Rules, 2009. Use approved MC4 connectors and double‑pole circuit breakers.
- Fire Safety – Install a fire‑break panel and keep a clear 0.5 m zone around the inverter for ventilation.
Environmental and Land Use
- Shadow‑Free Requirement – The design must guarantee at least 80 % of the panel area receives unobstructed sunlight for the majority of the year.
- Waste Management – End‑of‑life panels must be handed over to an authorized recycler as per the E‑Waste (Management) Rules, 2016.
Documentation Checklist for Installers
- Customer’s electricity bill (last 3 months)
- Sanctioned load certificate
- Roof plan with dimensions, orientation, and tilt
- Shading analysis report (sun‑path diagram)
- System design drawings (single line diagram, layout)
- GST invoices for all components
- Subsidy application forms and supporting documents
- LOP from DISCOM
- Net‑metering agreement and bi‑directional meter receipt
Maintaining a digital folder for each project within the installer’s operating system ensures nothing is missed during audits.
Penalties for Non‑Compliance
- Incorrect GST filing – Up to 100 % of the tax amount plus interest.
- Unauthorized net‑metering – DISCOM may disconnect the system and impose a fine of up to ₹ 10,000.
- Safety violations – Can attract penalties under the Electricity Act and may lead to insurance claim rejections.
By adhering to these rules and keeping all paperwork up to date, installers protect their reputation, avoid costly fines, and build trust with customers and utilities alike.
Frequently Asked Questions
1. What is the first step in the solar sales process india lead journey?
The journey begins with a lead capture, often through WhatsApp or a web form. The installer records the contact, notes the property type and asks for the monthly electricity consumption. This information feeds the sizing calculator and sets the stage for a site survey, which is the bridge between a lead and a formal proposal.
2. How do I qualify a lead before scheduling a site survey?
Qualification involves confirming the roof has enough shadow‑free area (80‑100 sq ft per kW) and that the customer’s budget matches a realistic system size. Ask for the latest electricity bill to estimate monthly units and check the sanctioned load with the local DISCOM. A quick phone call can weed out unrealistic expectations.
3. Why is a site survey critical for accurate sizing?
A site survey measures the exact usable roof area, checks orientation (south‑facing is ideal), and identifies shading from chimneys or trees. It also verifies structural strength for mounting. Without this data, the proposal may over‑size the system, leading to higher costs, or under‑size it, causing insufficient bill reduction.
4. How many units can a 3 kW rooftop system generate per day?
In most Indian locations a 3 kW system produces roughly 4‑4.5 units per kW each day, giving about 12‑13.5 units daily on average. Seasonal variation means winter months may generate a little less, while summer can be a touch higher. Over a month this translates to roughly 360‑400 units, enough to offset a typical 300‑400 unit household bill.
5. What is the difference between on‑grid and hybrid systems for Indian homes?
On‑grid (grid‑tied) systems are the cheapest and feed excess power to the utility, but they shut down during a power cut for safety (anti‑islanding). Hybrid systems add a battery, allowing essential loads to run when the grid fails. The battery adds cost but provides backup for critical appliances like fans or medical equipment.
6. How does net metering work after installation?
Once the inverter and net‑meter are commissioned, any surplus electricity generated flows back to the DISCOM and is credited against future consumption. The credit is usually applied on a monthly basis. The installer must submit the net‑meter reading to the DISCOM, and the customer sees a reduced bill rather than a zero bill.
7. What maintenance is required for rooftop solar in India?
Maintenance is minimal. Panels should be cleaned twice a year, more often in dusty regions, to remove soiling that reduces output. An annual electrical health check by a qualified technician ensures wiring, connectors and the inverter are in good condition. The system’s performance can be monitored remotely through the inverter’s app or a cloud dashboard.
8. How do subsidy and GST calculations affect the proposal price?
The Indian government offers a subsidy of up to 30 % on the system cost for residential installations, subject to income criteria and state‑specific caps. GST is levied at 18 % on the net cost after subsidy. A correct calculation ensures the customer sees the true out‑of‑pocket expense and avoids surprise post‑installation bills.
9. Can I use the same proposal template for residential and commercial leads?
While the core layout can stay the same, commercial proposals often include larger system sizes, higher inverter capacities, and may need to address multiple load centers. Residential proposals typically focus on a single inverter, a simpler mounting design, and emphasize bill reduction. Tailoring the language to the audience improves conversion.
10. How long does the DISCOM approval process usually take?
Approval time varies by state and DISCOM, but most approvals are granted within 15‑30 days after the application and site plan are submitted. Delays can occur if the paperwork is incomplete or if the site survey report lacks required details. Keeping a checklist of required documents helps speed up the process.
11. What documentation should I ask the customer to provide?
Ask for the latest electricity bill, property ownership proof, sanctioned load certificate, and any prior building permission if the roof is a common area in an apartment. These documents are needed for the DISCOM application, subsidy claim, and to verify that the roof can support the mounting structure.
12. How do I calculate the budget for a 5 kW system in a tier‑2 city?
Start with the base equipment cost (panels, inverter, mounting, wiring). Apply the applicable state subsidy (e.g., 30 % of the net cost) and then add GST of 18 % on the reduced amount. Include installation labour, permitting fees, and a small contingency for unexpected work. The final figure is presented as a clear, itemised proposal.
13. Is financing available for residential solar leads?
Many banks and NBFCs offer solar loans with tenures of 5‑7 years and interest rates around 9‑11 %. Installers can partner with these lenders to provide the customer a “pay‑later” option, making the upfront cost more affordable. The loan amount usually covers the post‑subsidy price, reducing the customer’s cash outflow.
14. How can I use WhatsApp to manage leads efficiently?
WhatsApp allows instant communication, quick sharing of documents, and real‑time updates on survey dates or approval status. By integrating the chat with a CRM, each conversation is logged, reminders are set, and the lead moves through the sales funnel without manual data entry. This keeps the pipeline tidy and reduces missed follow‑ups.
15. What are the common objections from leads and how to handle them?
Typical objections include high upfront cost, doubts about savings, and fear of roof damage. Counter these by showing a clear bill‑reduction projection, explaining the subsidy and financing options, and presenting case studies of similar roofs where mounting caused no damage. A transparent warranty on mounting and panels also builds trust.
16. How does orientation affect the energy output of a rooftop system?
South‑facing roofs receive the most sunlight throughout the day in India, yielding the highest daily generation. East‑ or west‑facing roofs still work well but may produce 5‑10 % less energy. North‑facing roofs are generally unsuitable unless they have a steep tilt or reflective surfaces. The design stage should optimise tilt close to the local latitude.
17. What is the typical timeline from lead to commissioning?
A well‑managed process can move from lead capture to commissioning in 45‑60 days: 5‑7 days for qualification, 7‑10 days for site survey and design, 15‑20 days for DISCOM approval, 7‑10 days for procurement and installation, and 2‑3 days for testing and handover. Delays usually happen in the approval or procurement stages.
18. How do I track installation progress for multiple projects?
Use a project‑management dashboard that logs each stage – survey, design, approval, mounting, wiring, inverter installation, and commissioning. Assign a status colour (e.g., green for completed, amber for pending) and set alerts for upcoming deadlines. This visibility helps installers allocate crews efficiently and keep customers informed.
19. What warranty terms should I communicate to the customer?
Solar panels typically carry a 10‑year product warranty and a 25‑year performance guarantee. Inverters have a 2‑5‑year warranty, extendable at extra cost. Mounting structures usually come with a 10‑year corrosion warranty. Clarify who handles warranty claims – the installer or the equipment supplier – to avoid confusion later.
20. How can I upsell battery storage to an on‑grid lead?
Identify customers who experience frequent power cuts or have critical loads like medical equipment. Explain that a hybrid system adds a battery, allowing those loads to run uninterrupted. Provide a cost‑benefit analysis showing the extra upfront cost versus the value of backup power and potential additional savings from peak‑shaving.
21. What role does the inverter play in system performance?
The inverter converts DC from the panels to AC for home use and synchronises with the grid. Its efficiency (often 95‑98 %) directly impacts how much generated energy reaches the load. Choosing an inverter with a proper rating – usually 1.1‑1.2 times the system kW – avoids clipping and ensures stable operation.
22. How do I stay updated on changing subsidy rules across states?
Subscribe to the Ministry of New and Renewable Energy (MNRE) newsletters, follow state renewable energy department releases, and join industry forums. Maintaining a spreadsheet of state‑wise subsidy caps and eligibility criteria helps quickly adjust proposals when rules change, ensuring the price you quote is always accurate.
Conclusion
Navigating the solar sales process india lead journey requires a clear roadmap—from the first WhatsApp inquiry to the final net‑meter reading. installers who rigorously qualify leads, conduct precise site surveys, and generate subsidy‑aware proposals see higher conversion rates and happier customers. By standardising each step—lead capture, sizing, design, DISCOM approval, installation, and commissioning—businesses can shrink the typical 45‑60 day cycle and scale operations across multiple cities.
Technology plays a pivotal role. A purpose‑built operating system for solar installers can automate lead tracking, embed the latest GST and subsidy calculators, and store every site‑survey report in one place.
