Tier-1 TOPCon panels, a 25-year performance warranty, and the PM Surya Ghar subsidy filed end to end by us. Most homes we install break even in under five years — and keep generating for twenty more.

30-second estimate
Move the slider to your average monthly electricity bill. Everything else updates live — system size, subsidy, payback period and lifetime savings.
No sign-up, nothing stored. This runs entirely in your browser.
Indicative only. Savings are capped at 92% of your bill because fixed and demand charges survive net metering, and lifetime figures assume 3% annual tariff escalation with 0.5% panel degradation. Actual generation depends on roof orientation, shading, tilt, soiling and your DISCOM tariff slab — a site survey replaces every number above with a measured one.

How it works
The installation itself takes days. The timeline is driven by DISCOM approval — which is exactly the part we handle for you.
An engineer measures shadow-free roof area, checks sanctioned load, and inspects the meter and earthing.
Day 1–2A shaded 3D layout, generation estimate, bill of materials and a fixed quotation with subsidy already applied.
Day 3–5National portal registration, DISCOM application and net-meter request, all filed by us in your name.
Day 5–20Mounting structure, panels, inverter, DC/AC cabling, earthing and lightning arrestor.
2–4 daysDISCOM inspection, net meter fitted, system synchronised, subsidy credited to your bank account.
Day 25–40PM Surya Ghar: Muft Bijli Yojana
Residential consumers get a direct bank credit after installation and inspection. Here is exactly how much, and exactly what we do about it.
| System size | Typical suitability | Subsidy |
|---|---|---|
| 1 kW | Bill up to ₹1,200 | ₹30,000 |
| 2 kW | Bill ₹1,200–2,500 | ₹60,000 |
| 3 kW | Bill ₹2,500–4,000 | ₹78,000 |
| 4 kW and above | Bill above ₹4,000 | ₹78,000 (capped) |
₹30,000 per kW for the first 2 kW, ₹18,000 for the third kW, capped at ₹78,000. Housing societies for common facilities are assisted separately at ₹18,000 per kW up to 500 kW.
You sign. We file. Nothing in this list is billed as an extra.

An engineer visits, measures and gives you a written proposal. If solar does not make sense on your roof, we will tell you that too.
Straight answers
Plan on roughly 70–90 sq ft of shadow-free roof per kilowatt with modern high-efficiency panels. A typical 3 kW home system needs about 220–270 sq ft; a 5 kW system about 350–450 sq ft.
A grid-tied rooftop system in most of India generates about 4 units per kW per day — roughly 1,460 units per kW per year. At a tariff near ₹8 per unit, each kilowatt offsets close to ₹11,500 of electricity annually.
So a 3 kW system typically removes ₹30,000–₹36,000 from annual bills. Use the calculator above for your own numbers.
Under PM Surya Ghar: Muft Bijli Yojana, residential consumers receive ₹30,000 per kW for the first 2 kW and ₹18,000 for the third kW, capped at ₹78,000 for systems of 3 kW and above. It is credited directly to your bank account after installation and inspection. Commercial and industrial connections are not eligible for this residential scheme, but may claim accelerated depreciation.
Physical installation takes two to four days for a home. The full timeline from survey to grid synchronisation is typically 25 to 40 days, because the DISCOM application, net-meter sanction and inspection run in parallel with procurement.
Panels: 12-year product warranty and 25-year linear performance warranty guaranteeing at least 87% output in year 25. String inverters: 5–10 years. Micro inverters: 25 years. Lithium batteries: 10 years or 6,000 cycles. Our installation workmanship: 5 years.
A grid-tied system without batteries draws from the grid when generation is low and exports the surplus during the day. Net metering credits exported units against imported ones, so the annual bill is what matters, not any single day. Adding battery storage covers outages and evening load.
Not when it is mounted correctly. We use ballasted or chemically-anchored galvanised structures with proper waterproofing at every penetration, and we warrant that workmanship for five years. On a terrace, the panels actually reduce heat ingress into the slab below.
Dry cleaning every two to four weeks in dusty regions, and a professional inspection twice a year. Soiling is the single largest avoidable loss — an uncleaned array can lose 8–15% of its output. Two annual service visits are included free for the first two years.
