Skip to content Enter your monthly electricity bill and get your solar system size, installation cost, government subsidy, and savings — in seconds. No technical knowledge needed.
Solar power helps you cut electricity bills and gain energy independence. This tool shows exactly how much you can save with a rooftop solar system — for any home across India. No technical knowledge needed.
Enter your state and average monthly electricity bill. The calculator converts it into units consumed, estimates the ideal system size for your home, and applies your state's solar generation potential to give accurate, localised results.
Your monthly bill tells us your consumption. We convert it to units (kWh) using your state's actual electricity tariff.
We calculate the exact solar capacity (kW) your roof needs using real solar generation data for your state's climate.
Get your monthly and yearly savings, government subsidy, net cost, panel count, and payback period — instantly.
The right system size depends on your monthly electricity consumption. A home consuming around 300 units per month typically needs a 2–3 kW system. Higher consumption homes (500+ units) may need 4–5 kW or more.
Bill ₹1,500–₹3,000 · ~1–2 kW · ~100–200 sq ft roof area
Bill ₹3,000–₹6,000 · ~3–4 kW · ~300–400 sq ft roof area
Bill ₹6,000–₹15,000 · ~5–10 kW · ~500–1,000 sq ft roof area
Solar panel installation in India typically costs ₹50,000–₹60,000 per kW, inclusive of panels, inverter, mounting structure, wiring, and installation. After applying the government subsidy, the effective cost drops significantly.
| System Size | Gross Cost | Govt. Subsidy | Net Cost |
|---|---|---|---|
| 2 kW | ₹1,10,000 | − ₹60,000 | ₹50,000 |
| 3 kW | ₹1,65,000 | − ₹78,000 | ₹87,000 |
| 5 kW | ₹2,75,000 | − ₹78,000 | ₹1,97,000 |
| 10 kW | ₹5,50,000 | − ₹78,000 | ₹4,72,000 |
A well-designed rooftop solar system can reduce your electricity bill by 80–90%. Over a 25-year panel lifespan, most homeowners save ₹8–25 lakhs in electricity costs. Solar also protects you from rising tariffs, which have increased 5–8% annually in India.
Solar covers most of your home's daily consumption. Your grid bill drops dramatically from month one.
After the payback period, every unit generated is pure savings — zero cost for the next 20+ years.
Surplus power feeds back to the grid. Your meter runs backwards — you earn credits reducing your monthly bill.
Under the PM Surya Ghar Muft Bijli Yojana (2024), Indian homeowners can claim a central government subsidy on residential rooftop solar. It is a direct benefit transfer — credited straight to your bank account. Our team handles all paperwork on your behalf.
Most residential solar systems in India recover their cost in 3 to 5 years. The exact payback depends on your bill, state electricity tariff, and system size. After payback, you generate free electricity for the next 20+ years.
Modern panels are rated at 540W–600W each. A standard 550W panel is the most common residential choice. Each kW of solar capacity requires approximately 100 sq ft of shadow-free roof area facing south or south-west.
~4 panels (550W) · ~200 sq ft of roof needed
~6 panels (550W) · ~300 sq ft of roof needed
~9–10 panels (550W) · ~500 sq ft of roof needed
Yes — and the numbers are better than ever. India's electricity tariffs rise consistently every year. Solar locks your energy cost at zero for 25 years from day one of installation. It reduces your carbon footprint, protects you from price hikes, and adds value to your property.
A quality installation from a trusted company includes government-approved equipment, licensed electricians, and a full system warranty. With payback in 3–5 years and 20+ years of free power after that, solar is one of the best financial decisions a homeowner can make in India today.
