Ultimate Guide to pm surya ghar old rooftop Subsidy

Poonam Verma · 25 Dec 2024

The pm surya ghar old rooftop scheme, officially known as PM Surya Ghar Muft Bijli Yojana, was launched to give Indian households up to 300 kWh of free electricity each month. Since its debut, the central subsidy structure and procedural steps have seen notable tweaks. If you are a homeowner thinking about installing a rooftop solar system, understanding these changes is essential to maximise savings and avoid delays. This article breaks down the updated subsidy amounts, eligibility criteria, application flow, and what the new rules mean for your pocket.

Under the revised framework, the central government provides Rs 30,000 per kW for the first 2 kW of a residential grid‑connected system. For capacities between 2 kW and 3 kW, an additional Rs 18,000 per kW is offered, but the total central grant is capped at Rs 78,000 for any system of 3 kW or larger. These figures are consistent across the country; however, many states may add their own top‑up subsidies, so it is wise to check with your local DISCOM or the state portal for exact amounts.

To claim the subsidy, applicants must register on the official portal pmsuryaghar.gov.in, obtain a feasibility approval from their DISCOM, and install the system through a vendor registered under the scheme. After installation, a net‑metering agreement with the DISCOM is mandatory before the subsidy is credited directly to the applicant’s bank account. The process is designed to be transparent and largely digital, but each step requires careful documentation, especially proof of roof ownership and a clean electricity bill history.

For installers, the evolving subsidy landscape creates both opportunities and responsibilities. Accurate proposal generation that reflects the capped central grant, plus any state‑specific top‑ups, is crucial. Platforms like SolarSwytch help installers automate subsidy‑aware quotations, manage leads over WhatsApp, and track installations from start to finish, eliminating the need for manual spreadsheets. By staying informed about the pm surya ghar old rooftop changes, installers can offer homeowners a clear financial picture and faster project turnaround.

Overall, the updated scheme continues to target 1 crore households, aiming to deliver up to 300 units of free electricity per month per eligible home. While the central subsidy remains generous, the cap at Rs 78,000 encourages larger systems to be financially viable only when complemented by state incentives or personal investment. Homeowners should weigh the size of the system against their electricity consumption patterns, roof space, and the net‑metering benefits offered by their local DISCOM.

Quick Answer: The pm surya ghar old rooftop subsidy now caps the central grant at Rs 78,000 per system, with Rs 30,000/kW for the first 2 kW and Rs 18,000/kW for the next 1 kW, payable after DISCOM net‑metering approval.

pm surya ghar old rooftop — why this matters

India’s electricity demand is rising faster than the capacity of the grid can keep up with. In 2023, the country added roughly 130 GW of new generation, yet demand grew by about 8 % per year, putting pressure on distribution utilities and leading to higher tariffs for households. Rooftop solar offers a direct way for Indian homeowners to cut their electricity bills, reduce dependence on the grid, and contribute to the nation’s clean‑energy goals.

The PM Surya Ghar Muft Bijli Yojana (often shortened to “PM Surya Ghar”) was launched to accelerate that shift. By providing a central subsidy of Rs 30,000 per kW for the first 2 kW and an additional Rs 18,000 per kW for capacity between 2 kW and 3 kW, the scheme caps the total central assistance at Rs 78,000 for systems of 3 kW and above. This means a typical 3 kW residential rooftop can receive up to Rs 78,000 off the capital cost, making the pay‑back period drop from 7–9 years to around 4–5 years for many families.

The scale of the opportunity

MetricPre‑PM Surya Ghar (old rooftop subsidy)PM Surya Ghar (current)
Central subsidy per kWRs 30,000 for first 2 kW onlyRs 30,000/kW (0‑2 kW) + Rs 18,000/kW (2‑3 kW)

EligibilityResidential only, no prior subsidyResidential only, no prior subsidy, roof ownership, valid DISCOM connection
Application channelState portals, varied processSingle national portal pmsuryaghar.gov.in with DISCOM verification

The table shows that the old rooftop subsidy (the phrase “pm surya ghar old rooftop” in many searches) was limited to 2 kW and offered a flat Rs 30,000 per kW. Homeowners who wanted a larger system—say 3 kW to meet higher consumption—had to fund the extra capacity largely out of pocket. The revised scheme now rewards larger installations, encouraging more households to size their systems appropriately rather than being forced to install a minimal 2 kW setup.

How the subsidy translates into bill savings

Consider a typical Indian household that consumes 250 kWh per month. With a 3 kW rooftop system, the average solar generation is about 4 kWh per kW per day, or roughly 360 kWh per month. After net‑metering, the household can offset its entire consumption and still have surplus that the DISCOM buys back at the prevailing tariff.

  • Without subsidy: Capital cost for a 3 kW system (including panels, inverter, mounting, installation) is roughly Rs 2,10,000.
  • With PM Surya Ghar subsidy: Central assistance of Rs 78,000 reduces the out‑of‑pocket cost to Rs 1,32,000.
  • Annual savings: Assuming an average electricity tariff of Rs 8 per kWh, the household saves about Rs 2,000 per month (Rs 24,000 per year).
  • Pay‑back period: ~5.5 years, after which the system continues to generate free electricity for the remaining 20‑25 year lifespan.

These numbers illustrate why the policy change matters: the higher subsidy for larger capacities makes rooftop solar financially viable for a broader segment of the middle‑class market, not just early adopters with high disposable income.

The broader impact on the grid

When a million households each offset 300 kWh per month, the aggregate reduction is 300 GWh per month—equivalent to the output of a 350 MW coal plant operating at full capacity. This reduction eases peak‑load stress on distribution networks, lowers transmission losses, and reduces the need for costly grid upgrades. Moreover, the scheme aligns with India’s target of 450 GW of solar capacity by 2030, as rooftop installations are expected to contribute at least 30 GW of that total.

The role of installers

For solar installers, the policy change brings both opportunities and responsibilities. The central subsidy is now tied to a net‑metering agreement and DISCOM feasibility approval before any payment is released. Installers must therefore:

  1. Register on the national portal (pmsuryaghar.gov.in).
  2. Submit the project details (capacity, roof dimensions, shading analysis).
  3. Coordinate with the local DISCOM for feasibility and net‑metering contract.
  4. Complete installation according to the vendor‑registered standards.
  5. Facilitate the final inspection and ensure the subsidy is credited to the homeowner’s bank account.

Because the process is now more standardized, installers who use a digital platform that integrates subsidy calculations, GST compliance, and CRM can streamline the workflow, reduce errors, and close deals faster. Tools that automate the generation of subsidy‑aware proposals are especially valuable in this environment.

The image above outlines the end‑to‑end journey—from the homeowner’s online registration to the final credit of the subsidy—helping readers visualise each step.

Why homeowners should act now

  • Limited funding: The central budget for the scheme is finite; early adopters are more likely to secure the full Rs 78,000 subsidy.
  • Rising electricity tariffs: With the average residential tariff climbing by about 5 % annually, the pay‑back period shortens each year.
  • Increasing solar panel efficiency: Modern panels now deliver 18‑20 % efficiency, meaning a 3 kW system can be fitted on smaller roofs than a few years ago.

In short, the PM Surya Ghar old rooftop policy has evolved to become more inclusive and financially attractive. Homeowners who understand the new subsidy structure can make an informed decision, size their system correctly, and reap substantial savings while contributing to a greener grid.

Common Misconceptions

Myth 1: “The subsidy only covers 2 kW, so larger systems get no benefit.”

Reality: Under the revised PM Surya Ghar Muft Bijli Yojana, the central subsidy is Rs 30,000 per kW for the first 2 kW and an additional Rs 18,000 per kW for the next 1 kW. This means a 3 kW system receives a total of Rs 78,000, the maximum central assistance. Larger systems beyond 3 kW do not receive extra central subsidy, but many states offer top‑ups that can further reduce the cost.

Myth 2: “I must apply through my state’s portal; the central portal is only for information.”

Reality: The official application portal is pmsuryaghar.gov.in for all eligible households across India. The process is uniform: register, obtain DISCOM feasibility, install, and receive the subsidy. State‑specific portals may exist for additional top‑ups, but the central subsidy is always processed through the national site.

Myth 3: “Only new homes can claim the subsidy because they have fresh roofs.”

Reality: Any residential household with roof ownership rights and a valid electricity connection can apply, regardless of the age of the building. The key eligibility criteria are: no prior solar subsidy received, roof ownership, and compliance with local building codes. Existing homes can retrofit solar panels as long as the structural integrity of the roof is verified.

Myth 4: “The subsidy is a grant; I will receive cash directly.”

Reality: The subsidy is credited to the homeowner’s bank account after the installation is inspected and the net‑metering agreement is in place. It is not a cash hand‑out at the time of registration. The workflow ensures that the system is correctly installed, connected to the grid, and that the DISCOM has approved the net‑metering arrangement before any funds are released.


By debunking these myths, homeowners can avoid common pitfalls and move confidently through the application process.

pm surya ghar old rooftop — how it works / what you must know

Understanding the pm surya ghar old rooftop scheme is the first step toward a successful solar installation. Below we outline the entire journey, from eligibility to final subsidy credit, with clear sub‑sections for easy reference.

1. Who Can Apply?

  • Residential household with a valid electricity connection.
  • Must own the roof or have documented permission from the property owner.
  • No prior solar subsidy (central or state) should have been received for the same property.
  • Must have a DISCOM‑verified net‑metering agreement ready for the installation.

2. Application Workflow

7Inspection by DISCOMDISCOMInspection certificate
8Subsidy credit to bank accountMinistry of PowerBank details

Each step must be completed online wherever possible. The portal guides users with prompts and allows status tracking in real time.

3. Technical Requirements

  • System size: Minimum 1 kW, maximum unlimited but central subsidy caps at 3 kW.
  • Grid connection: Must be tied to the local distribution network; off‑grid systems are not eligible.
  • Net‑metering: The installed inverter must support net‑metering as per DISCOM guidelines.
  • Quality standards: Panels, inverters, and mounting structures must meet Indian Standards (IS 17046 for modules, IS 16212 for inverters).

4. Calculating Your Subsidy

The subsidy calculation follows a simple tiered formula:

  • For the first 2 kW: 2 kW × Rs 30,000 = Rs 60,000
  • If system size is 2.5 kW: Additional 0.5 kW × Rs 18,000 = Rs 9,000 Total central grant = Rs 69,000 (still below the Rs 78,000 cap).

For any system ≥3 kW, the central grant remains Rs 78,000 regardless of extra capacity. State top‑ups, where available, are added on top of this amount.

5. Role of State DISCOMs

While the central figures are uniform, many states offer additional subsidies or interest‑free loans. These amounts vary by state and are not standardized nationally. Homeowners should visit their state DISCOM website or contact the local office for precise details. The central portal provides links to each DISCOM’s portal for convenience.

6. Net‑Metering Benefits

Net‑metering allows excess solar generation to be fed back to the grid, earning a credit on the electricity bill. This credit is typically settled on a monthly basis, reducing the household’s net bill. The agreement must be in place before the subsidy is released, ensuring the system is truly grid‑interactive.

7. Timeline Expectations

  • Portal registration to DISCOM approval: Usually 7‑15 days, depending on document completeness.
  • Installation to inspection: 10‑20 days for a standard 2‑3 kW system.
  • Subsidy credit: Once inspection is cleared, the central grant is transferred within 30 days to the bank account provided.

For a smooth experience, keep all documents digitised and maintain regular communication with the vendor and DISCOM.

pm surya ghar old rooftop — costs, savings and returns

When evaluating a rooftop solar system, the financial picture hinges on three elements: initial outlay, subsidy impact, and ongoing savings from reduced electricity bills. Below we walk through each component using the ground‑truth subsidy figures.

1. Initial Capital Requirement

Typical costs for a residential grid‑connected system (including panels, inverter, mounting, wiring, and installation) range between Rs 45,000 to Rs 55,000 per kW. These figures are market averages and can vary based on equipment quality and installer rates.

System SizeCapital Cost (Range)Central Subsidy (Max)Net Capital after Subsidy
1 kWRs 45,000 – Rs 55,000Rs 30,000Rs 15,000 – Rs 25,000
2 kWRs 90,000 – Rs 110,000Rs 60,000Rs 30,000 – Rs 50,000
3 kWRs 135,000 – Rs 165,000Rs 78,000Rs 57,000 – Rs 87,000
4 kWRs 180,000 – Rs 220,000Rs 78,000 (capped)Rs 102,000 – Rs 142,000

The central subsidy caps at Rs 78,000 for systems of 3 kW and above, so larger installations rely more on state top‑ups or personal investment.

2. Annual Electricity Savings

Assuming an average household consumption of 150 kWh per month (1,800 kWh per year) and a solar yield of 4.5 kWh per kW per day, a 3 kW system can generate roughly 4,945 kWh annually. After net‑metering credits, the household may offset the entire consumption, effectively receiving up to 300 kWh free per month as per the scheme’s target.

  • Average tariff (as of 2024): Rs 8 per kWh.
  • Annual bill without solar: 1,800 kWh × Rs 8 = Rs 14,400.
  • Annual savings with solar (net‑metered): Up to Rs 14,400 (full offset) plus any excess exported credits.

3. Payback Period

Using the net capital cost after central subsidy (ignoring state top‑ups for a conservative estimate):

  • 2 kW system: Net cost Rs 30,000 – Rs 50,000; annual savings approx. Rs 9,600 → Payback 3‑5 years.
  • 3 kW system: Net cost Rs 57,000 – Rs 87,000; annual savings approx. Rs 14,400 → Payback 4‑6 years.

These periods shrink further if a state provides additional subsidy or low‑interest loan.

4. Return on Investment (ROI)

After the payback period, the system continues to generate electricity at virtually zero marginal cost, delivering pure profit for the remaining 15‑20 years of panel life.

  • Simple ROI (over 20 years) for a 3 kW system:
    • Total savings = 20 years × Rs 14,400 = Rs 288,000
    • Net investment = Rs 70,000 (average)
    • ROI ≈ 311% (excluding inflation and maintenance).

5. Maintenance & Other Costs

Routine cleaning and inverter warranty service are the main recurring expenses, typically Rs 2,000‑Rs 3,000 per year. These are modest compared to the electricity bill savings.

6. Impact of State Top‑Ups

If a state offers an additional Rs 20,000 per kW for the first 2 kW, the net capital for a 2 kW system falls to Rs 10,000‑Rs 30,000, reducing the payback to 1‑2 years. Homeowners should verify the exact amount on their state DISCOM portal.

7. Financing Options

Many banks now provide zero‑interest loans for solar under the PM Surya Ghar scheme, linking repayment to the expected savings. This makes the upfront cost negligible for many families.

pm surya ghar old rooftop — use cases and scenarios

1. First‑time homeowner in a Tier‑2 city

Ravi, a 32‑year‑old IT professional living in Indore, owns a 120 sq ft roof with minimal shading. He consumes about 250 kWh per month and wants to reduce his electricity bill. After checking the PM Surya Ghar Muft Bijli Yojana portal, he learns that a 3 kW system will fetch the maximum central subsidy of Rs 78,000.

Steps Ravi follows:

  1. Online registration on pmsuryaghar.gov.in and upload of his electricity bill, property documents, and roof photos.
  2. DISCOM feasibility – the local DISCOM (MP Power) validates that his roof can host a 3 kW system and issues a net‑metering agreement draft.
  3. Vendor selection – he contacts a certified installer who uses a digital platform to generate a subsidy‑aware proposal. The proposal automatically shows the Rs 78,000 deduction, GST calculations, and the final out‑of‑pocket cost of Rs 1,32,000.
  4. Installation and inspection – the installer completes the work in two days, and the DISCOM inspector signs off on the net‑metering setup.
  5. Subsidy credit – within a month, the Rs 78,000 subsidy is transferred directly to Ravi’s bank account.

Ravi now enjoys a monthly electricity bill of Rs 500–600, compared with the previous Rs 2,000, and the system pays for itself in just over five years.

2. Small business owner with a dual‑purpose roof

Meena runs a boutique in Jaipur that occupies a 200 sq ft shop with a flat roof. She wants to power the shop’s lighting and air‑conditioners while also providing free electricity to her home upstairs. Because the PM Surya Ghar scheme is limited to residential installations, Meena cannot claim the central subsidy for a commercial‑only system. However, she can install a combined residential‑commercial setup where the portion serving her home qualifies.

  • Residential portion: 2 kW dedicated to her apartment, eligible for Rs 60,000 central subsidy.
  • Commercial portion: 1 kW for the boutique, no central subsidy but can benefit from any state‑level top‑up if applicable.

By structuring the system this way, Meena reduces her home electricity cost dramatically while still improving the boutique’s energy efficiency. She must ensure that the net‑metering agreement clearly separates the two load categories to stay compliant.

3. Retrofitting an older apartment building

A housing cooperative in Kolkata manages a 10‑unit apartment block built in the 1990s. The collective roof area is sufficient for a 30 kW system. The cooperative applies for the PM Surya Ghar subsidy on behalf of each unit, treating each 3 kW slice as a separate residential installation.

  • Total central subsidy: 10 units × Rs 78,000 = Rs 7,80,000.
  • Cost sharing: The cooperative negotiates a bulk installation discount, reducing the per‑unit out‑of‑pocket cost to about Rs 1,30,000 after subsidy.

Because the scheme requires individual ownership rights, each unit must have a separate net‑metering contract with the DISCOM. The cooperative coordinates this paperwork through a single installer who uses a software platform to generate ten subsidy‑aware proposals, track each application, and ensure timely disbursement.

4. Migrating from an old rooftop subsidy to the new scheme

Before the policy change, many homeowners installed 2 kW systems under the old rooftop subsidy, receiving only Rs 60,000 centrally. With the new structure, they can upgrade to 3 kW by adding an extra 1 kW panel. The additional central subsidy of Rs 18,000 (plus any state top‑up) makes the upgrade financially attractive.

Upgrade pathway:

  • Step 1: Verify that the existing inverter can handle the extra kilowatt; if not, replace it (cost often covered by the installer’s package).
  • Step 2: Submit a supplementary application on pmsuryaghar.gov.in, citing the original installation ID and the proposed increase.
  • Step 3: Obtain DISCOM approval for the higher capacity and new net‑metering reading.
  • Step 4: Install the additional panel(s) and complete the inspection.

The homeowner receives the Rs 18,000 top‑up directly, reducing the incremental cost of the upgrade to roughly Rs 12,000 after accounting for the subsidy. This scenario shows how the revised policy encourages scaling up existing systems rather than leaving them undersized.

5. Leveraging state‑level top‑ups

While the central subsidy is uniform, many states provide additional financial assistance. The exact amount varies, and homeowners should consult their state DISCOM or the state portal for details. For example, some states may offer an extra Rs 20,000 per kW for systems above 3 kW, effectively increasing the total subsidy to over Rs 1,00,000 for a 4 kW installation.

To explore these options, readers can refer to our related article Special Category States: Getting up to Rs.1,17,000 Under PM Surya Ghar, which outlines how to identify eligible states and the steps to claim the top‑up.

6. The installer’s perspective – streamlining the workflow

Solar installers across India are adopting integrated software solutions that combine CRM, proposal generation, subsidy calculators, and GST compliance. By using a platform purpose‑built for the Indian market, installers can:

  • Generate subsidy‑aware quotes instantly, showing the homeowner exactly how much central assistance they will receive.
  • Track each application from portal registration through DISCOM approval, reducing manual follow‑ups.
  • Manage net‑metering contracts and schedule inspections, ensuring that the subsidy is released without delay.

Such digital tools replace cumbersome spreadsheets and phone‑based lead tracking, enabling installers to handle a higher volume of projects while maintaining accuracy.


Understanding the various use cases helps homeowners and installers see the practical benefits of the PM Surya Ghar old rooftop policy change. Whether you are a first‑time buyer, a small business owner, or part of a housing cooperative, the scheme now offers more flexibility, higher subsidies for larger systems, and a clear, online pathway to clean, affordable electricity.

  • Current Electricity Bill: ₹2,500 per month (average 250 kWh).
  • Objective: Install a rooftop solar system to eliminate the first 300 kWh of consumption each month and claim the central subsidy.

Step 1 – Deciding System Size

Rajesh measures his roof and finds that a 3 kW system will fit comfortably, leaving space for future expansion.

  • Subsidy Calculation:

    • First 2 kW → 2 × ₹30,000 = ₹60,000
    • Next 1 kW → 1 × ₹18,000 = ₹18,000
    • Total Central Subsidy: ₹78,000 (maximum for ≥3 kW).

Step 2 – Registering on the Portal

He visits pmsuryaghar.gov.in, creates an account, and fills in:

  • Name, PAN, Aadhaar, and contact details.
  • Address and electricity connection number.
  • Proposed system capacity: 3 kW.

The portal instantly shows the subsidy amount of ₹78,000 and asks for supporting documents.

Step 3 – Uploading Documents

Rajesh scans and uploads:

  1. Last three electricity bills (showing a regular consumption pattern).
  2. Property tax receipt confirming roof ownership.
  3. Aadhaar card for identity verification.

The portal acknowledges receipt and forwards the application to the Jaipur DISCOM for feasibility.

Step 4 – DISCOM Feasibility

The DISCOM reviews the connection details and schedules a short site visit (30 minutes). They confirm that net‑metering is permissible at Rajesh’s address and issue a Feasibility Approval Letter on the portal within 7 days.

Step 5 – Net‑Metering Agreement

Using the approval letter, Rajesh signs the net‑metering agreement with the DISCOM. He scans the signed document and uploads it back to the portal. This step unlocks the ability to install the system.

Step 6 – Choosing a Registered Vendor

Rajesh contacts three installers listed on the portal and selects SolarTech Solutions (registered vendor ID: STS‑2024‑001). He shares his portal application ID (PM‑2024‑RJ‑00123) with the vendor.

Step 7 – Installation

SolarTech orders the required panels, inverter, and balance of system (BOS) components. The installation proceeds as follows:

ActivityDuration
Civil mounting and wiring4 days
Electrical connections to the inverter1 day
Preliminary testing1 day
Total Installation Time6 days

The vendor prepares an invoice that includes the portal application ID and their registration number.

Step 8 – Commissioning Inspection

After installation, SolarTech requests a Commissioning Inspection via the portal. A DISCOM officer visits, checks:

  • Panel orientation and tilt.
  • Inverter capacity (3 kW).
  • Net‑metering meter reading.

The inspection report is uploaded within 2 days and marked “Approved”.

Step 9 – Final Document Submission

Rajesh now uploads three final files:

  1. The approved inspection report.
  2. The vendor invoice (showing ₹78,000 subsidy claim).
  3. The signed net‑metering agreement (again for record).

The portal validates the documents and moves the application to “Ready for Disbursement”.

Step 10 – Subsidy Credit

Within 15 days, the central authority transfers ₹78,000 directly to Rajesh’s bank account (linked during registration). He receives an SMS notification confirming the credit.

Step 11 – State Top‑Up (Optional)

Rajesh checks the Rajasthan DISCOM website and discovers a state‑level top‑up of ₹20,000 for systems up to 3 kW. He follows the separate state application process and receives the additional amount after another 10 days.

Step 12 – Savings Realised

With net‑metering active, Rajesh’s system generates roughly 4 kWh per day per kW in Jaipur’s climate, i.e., about 12 kWh per day for a 3 kW system. Over a month, this totals ≈360 kWh, covering his first 300 kWh free electricity quota.

  • Monthly Bill Before Solar: ₹2,500 (≈250 kWh) + occasional peaks.
  • Monthly Bill After Solar: ₹0 for the first 300 kWh, plus a small net‑metering charge for any excess export (often a credit).

Effectively, Rajesh saves ≈₹2,500 per month, recouping the ₹78,000 central subsidy in just over 3 years, while the state top‑up shortens the payback further.

Visual Summary

Key Takeaways from the Example

  • The central subsidy caps at ₹78,000 for any system of 3 kW or higher.
  • All steps must be completed on the official portal; any deviation can cause rejection.
  • State top‑ups are optional but can significantly boost total benefit.
  • Net‑metering is the linchpin – without a signed agreement, the subsidy will not be released.

pm surya ghar old rooftop – Alternatives and Comparison

While the PM Surya Ghar Muft Bijli Yojana remains the flagship central scheme for residential rooftop solar, several other programmes exist at the central and state level. Homeowners often wonder which option gives the best financial return. The table below summarises the main alternatives, their eligibility, subsidy caps, and key differentiators.

SchemeCentral Subsidy (per kW)Maximum Central BenefitEligibilityNet‑Metering RequirementState Top‑UpsTypical Processing Time*
PM Surya Ghar Muft Bijli Yojana₹30,000 for first 2 kW, ₹18,000 for 3rd kW₹78,000 (capped at ≥3 kW)Residential only, first‑time solar claim, valid electricity connection, roof ownershipMandatory – must have DISCOM net‑metering before subsidy creditVaries by state; link to state DISCOM for details30–45 days (portal + DISCOM)

*Processing time is an average estimate; actual duration depends on DISCOM efficiency and completeness of documents.

How to Choose the Best Option

  1. Check Central Eligibility First – If you qualify for PM Surya Ghar, you automatically receive the highest guaranteed central subsidy (₹78,000).
  2. Look for State Top‑Ups – After securing the central amount, visit your state DISCOM website or portal to see if an additional top‑up is offered. The amounts differ widely, so a quick check can add thousands of rupees to your benefit.
  3. Consider PMSY if You Missed PM Surya Ghar – The Pradhan Mantri Suryoday Yojana provides a flat ₹20,000 per kW and does not require you to have avoided other central subsidies. However, the total payout is usually lower than the combined PM Surya Ghar + state top‑up.
  4. Evaluate Commercial Needs Separately – Commercial rooftops are excluded from PM Surya Ghar but may qualify under state‑specific schemes or the PMSY (if the capacity is ≤5 kW).

Example Comparison

Assume a homeowner in a Special Category State wants a 3 kW system.

SchemeCentral SubsidyState Top‑UpTotal Cash ReceivedNet‑Metering Needed?
PM Surya Ghar + State Top‑Up₹78,000Up to ₹39,000 (state‑specific)Up to ₹1,17,000Yes
PMSY only₹60,000 (3 kW × ₹20,000)May have separate state benefit (often lower)Typically ≤ ₹80,000May be optional
State‑Only Scheme₹45,000 (assume ₹15,000/kW)None₹45,000Yes

From the table, the PM Surya Ghar route, combined with a special‑category state top‑up, yields the highest cash incentive.

Practical Tips

  • Always start at the central portal – The official site pmsuryaghar.gov.in is the only place to register for the central subsidy.
  • Document consistency is crucial – The same PAN, Aadhaar, and address must appear on all uploaded files; mismatches trigger rejections.
  • Maintain a copy of the DISCOM feasibility letter – This document is often requested again when applying for a state top‑up.
  • Use a software platform to manage the process – Installers can benefit from tools that auto‑populate subsidy calculations and generate compliant proposals, reducing manual errors.

By understanding the alternatives and their key metrics, Indian homeowners can make an informed decision that maximises financial savings while supporting the nation’s clean‑energy goals.


pm surya ghar old rooftop — rules, compliance and regulations

The pm surya ghar old rooftop scheme is governed by a set of clear regulations to ensure transparency and prevent misuse. Below are the critical compliance points every applicant and installer must observe.

1. Eligibility Verification

  • Residential status only: Commercial, industrial, or agricultural installations are excluded.
  • No prior subsidy: The household must not have received any central or state solar subsidy for the same roof.
  • Roof ownership: Legal proof of ownership or a notarised permission letter from the owner is mandatory.
  • Valid electricity connection: A recent electricity bill (within last 3 months) is required to confirm active supply.

2. Vendor Registration

Installers must be registered vendors on the PM Surya Ghar portal. Registration involves:

  • Providing GST registration, PAN, and an audited balance sheet.
  • Demonstrating experience with grid‑connected rooftop systems.
  • Signing an undertaking to comply with net‑metering standards and post‑installation inspections.

3. Net‑Metering Agreement

Before subsidy disbursement, the homeowner must sign a net‑metering contract with the local DISCOM. The agreement stipulates:

  • Export tariff: Usually the same as the retail rate, but can vary by DISCOM.
  • Metering equipment: Bi‑directional meters supplied by the DISCOM or approved third‑party.
  • Duration: Typically a 25‑year agreement aligned with the warranty period of the solar components.

4. Inspection and Certification

After installation, a DISCOM inspector conducts a site visit to verify:

  • Correct system sizing as per the approved proposal.
  • Compliance with safety norms (e.g., IEC 61730 for module safety, IEC 62446 for system testing).
  • Proper grounding and earthing as per IS 3043.

A Certificate of Compliance is issued only if all criteria are met; otherwise, corrective actions must be taken within a stipulated period (usually 15 days).

5. Documentation for Subsidy Claim

The final claim package uploaded on pmsuryaghar.gov.in must include:

  • Signed net‑metering agreement.
  • Inspection certificate.
  • Bank account details (Aadhaar‑linked) for subsidy credit.
  • Invoice from the registered vendor, clearly stating system capacity and GST.

All documents should be in PDF format and not exceed 5 MB per file.

6. Timeline and Penalties

  • False information or manipulation of roof area can lead to disqualification and a penalty of up to Rs 10,000.
  • Delays in providing required documents may result in interest accrual on the subsidy amount at the prevailing repo rate.
  • Failure to maintain the net‑metering agreement (e.g., disconnecting the system) can trigger a recovery of the subsidy from the homeowner’s bank account.

7. State‑Specific Add‑Ons

While the central scheme provides a uniform grant, states may introduce:

  • Additional cash top‑ups.
  • Interest‑free loans.
  • Priority queue for DISCOM approvals.

Since amounts and processes differ, applicants should consult their state DISCOM portal or contact the local office for precise guidance. No specific state figures are quoted here to avoid misinformation.

8. Role of Software Platforms

Installers often use specialized software to manage the end‑to‑end workflow. Solutions like SolarSwytch help generate subsidy‑aware proposals, track lead status over WhatsApp, and log inspection outcomes, ensuring that every compliance checkpoint is met without resorting to manual spreadsheets.

Adhering strictly to these rules not only speeds up subsidy release but also safeguards the homeowner from future legal or financial hassles. By staying organized and following the official portal’s checklist, the pm surya ghar old rooftop journey can be smooth and rewarding.
