PM Surya Ghar Yojana — what every Indian household needs to know
A plain-English walkthrough of India's flagship rooftop solar subsidy — eligibility, the ₹78,000 ceiling, the application flow, and what actually happens after you apply.
If you have a roof, an electricity bill and a savings account that's earning 6%, the most under-discussed financial decision in India today is whether to put solar on that roof. The Government of India's PM Surya Ghar Muft Bijli Yojana — launched in February 2024 — exists to remove the friction from that decision. After installing well over 1,500 rooftop systems through Sahayog Energy, I want to walk you through what the scheme actually is, what it pays, and how to think about it without the marketing layer.
The scheme, in one paragraph
PM Surya Ghar provides a Central Financial Assistance (CFA) — a one-time subsidy paid directly to the consumer's bank account — when an Indian household installs a grid-connected rooftop solar system. The ceiling is ₹78,000 for systems of 3 kW and above. The scheme runs through the Ministry of New and Renewable Energy (MNRE) and is delivered via the National Portal at pmsuryaghar.gov.in. It is not a loan, not a tax credit and not a complicated waiver — it is a direct cash deposit into your account once your system is installed, inspected and net-metered.
The subsidy slabs
The CFA is calculated by capacity, not by spend. The current slabs are: ₹30,000 for the first kW, ₹30,000 for the second kW, ₹18,000 for the third kW — capped at ₹78,000 total. A 1 kW system gets ₹30,000. A 2 kW gets ₹60,000. A 3 kW (or any larger system) gets the full ₹78,000.
What this means in practice: most Indian households with a typical 200–400 unit monthly bill are sized at 3 kW. So most households get the full ceiling. The subsidy is the same whether you install a 3 kW or a 10 kW system — but the larger system covers more of your bill and generates more annual savings.
Eligibility — who actually qualifies
You qualify if you are an Indian citizen, own a house with a roof suitable for solar panels, have a valid electricity connection in your name, and have not already availed any other central subsidy for a solar system. The system has to be installed by a vendor empanelled with your local DISCOM (your state's electricity distribution company). It has to be net-metered, which means the installation has to go through the formal sanction-and-inspection process — informal installations don't qualify.
The application flow — what actually happens
Step one — register at pmsuryaghar.gov.in with your DISCOM, consumer number, mobile number and email. Step two — apply for feasibility approval (the DISCOM checks that your transformer and feeder can handle the proposed system). Step three — once feasibility is approved, install through any DISCOM-empanelled vendor. Step four — the installer applies for net-metering and a DISCOM inspector visits. Step five — once the meter is replaced and the system is commissioned, the CFA is auto-credited to your bank account within ~30 days.
End to end, the process takes 30 to 60 days in a well-managed state. In states with backlog, it can stretch to 90 days. That's the honest range, not the optimistic one.
The payback math
A standard 3 kW residential system in Gujarat costs roughly ₹1.6–1.9 lakh installed, before subsidy. After the ₹78,000 CFA, the net out-of-pocket is ₹85,000–1,15,000. That system generates roughly 4,200 units per year at our latitude. At an average residential tariff of ₹7/unit, that's ~₹29,000 in annual savings.
Payback period: roughly 3 to 4 years on the net investment. The system has a 25-year warranted life. Years 5 to 25 are essentially free electricity. That's a tax-free, government-subsidised, real-asset return that beats almost anything else available to an Indian household.
What goes wrong — and how to avoid it
The single most common failure mode I see is the wrong installer. Some vendors quote 30% below market by using sub-tier modules, undersized inverters and substandard mounting structures. The system technically works for two years, then degradation accelerates, the inverter trips repeatedly and the customer is stuck with a non-performing asset. The subsidy doesn't pay for itself if the equipment doesn't last.
The fix is mundane but unavoidable: use a DISCOM-empanelled installer with verifiable installations you can visit, insist on Tier-1 modules with a 25-year power warranty, a 10-year product warranty on the inverter, and a written annual maintenance contract. Compare two or three quotes, but don't pick on price alone — pick on the answers to four questions: which modules, which inverter, what mounting structure, who maintains it.
If you're in Gujarat
Gujarat has one of the smoothest DISCOM ecosystems in the country (PGVCL, MGVCL, UGVCL, DGVCL), strong solar irradiance, and a state government that has actively pushed rooftop adoption. The Surya Ghar process here is, frankly, easier than in most other states. If you've been on the fence, this is the year to act.
Sahayog Energy is empanelled across all four Gujarat DISCOMs. We do the full Surya Ghar paperwork end-to-end so the homeowner only signs documents, never chases departments. Reach the office at info@vijaygalani.com or via sahayogenergy.com.
