Packages & prices
Many solar companies tell you the price only after a visit. We publish ours, because a fair price has nothing to hide.
Prices include GST and are for a standard rooftop installation. Every roof is different: if yours needs a raised structure, a longer cable run or extra civil work, we show it in your written quote at the free roof check, before you decide. The subsidy is credited to your bank account after inspection. EMI shown is an example bank loan; the bank sets the final rate and tenure.

₹30,000 per kW for the first 2 kW and ₹18,000 for the 3rd kW, so ₹78,000 is the maximum. It is the same across India.
Subsidy rules are set by the government and can change. We confirm your eligibility during the roof check.
Financing
Eligible customers may have financing options through participating lenders. Some current PM Surya Ghar loans are around 5.75% a year, but no rate is guaranteed: the lender decides the final rate, tenure, loan amount and approval.

One complete solution
From your EB bill to years of ownership, one team looks after every step, so nothing falls between a seller, an installer and the paperwork.
Long-term ownership
You are not renting electricity. You are owning a power-generating asset on your roof.
Rooftop solar is a long-term asset. It is designed to generate electricity for many years and to recover its cost through lower EB bills over time. How long that takes is an estimate, not a promise: it depends on your actual usage, your tariff, the system cost, the subsidy, any financing and how much your roof generates. We work it out for your home and give it to you in writing.
See my estimateHotels · Resorts · Factories · Warehouses · Commercial
Big roofs, big daytime loads, big bills. That's where solar works hardest, and the tax benefits make it even better.
*Tax benefits depend on your business, ownership and tax regime. PM Surya Ghar subsidy is for homes only. Please confirm with your CA; we share the documents they need.

Questions people ask us
For 3 kW or more: up to ₹1,08,000 in Puducherry (₹78,000 central + ₹30,000 UT) and up to ₹1,00,000 in Tamil Nadu (₹78,000 central + ₹22,000 state). For 2 kW: ₹80,000 in Puducherry and ₹70,000 in Tamil Nadu. All of it depends on current scheme rules and your eligibility.
The person named on the EB connection, straight into their bank account, after the system is installed, inspected and net-metered. We file the claim and keep you updated.
Yes. It makes less on cloudy days and more on sunny ones. What matters is the yearly total, which is why our Savings Guarantee is written per year.
Not with a standard on-grid system. It switches off during a power cut so that linemen working on the lines stay safe. If you want backup, we can add a hybrid inverter and battery. That part isn't covered by the subsidy.
Only if your roof needs something extra, such as a raised structure for a water tank or terrace use, a longer cable run or civil work. We tell you at the free roof check, in writing, before you pay anything. Nothing is added on installation day.
Yes. We use hot-dip galvanised structures built for coastal wind, anchored properly to your roof. During your free 5-year AMC our team checks the structure along with the panels and wiring.
Yes. Public-sector banks give collateral-free solar loans under PM Surya Ghar, at about 5.75% for loans up to ₹2 lakh (the bank decides the final rate). We help with the paperwork. You can use the subsidy to prepay the loan, so your EMI can end up smaller than your old EB bill.
You need about 100 sq ft of shade-free roof per kW. RCC terraces and sheet roofs both work. We check shade, strength and the EB connection for free.
No. The subsidy is paid to the person named on the connection, so you can apply in his name or transfer the connection first. We'll tell you which is faster.
For a typical 3 kW home, the price after subsidy equals about 2–3 years of saved EB bills. The panels are built to work 25–30 years, so you get up to 27 more years of savings. That is why we call it the best financial decision for your money.
Hotels and businesses don't get the PM Surya Ghar subsidy, but can usually claim up to 40% depreciation in the first year and GST input credit on the plant, on top of the bill saving. Please confirm with your CA; we share the documents they need.
