ExploreHow Much Do Solar Panels Cost For A House?
Residential solar in India ranges from ₹73,000–₹85,000 per kW installed; a typical 5 kW home system costs ₹3.5–4.5 lakh before subsidy, and around ₹2.7 lakh after PM Surya Ghar. In the USA, expect $2.50–$3.20 per watt installed before the 30% federal tax credit — about $12,500–$16,000 for a 5 kW system, dropping to roughly $8,800–$11,200 net.
Calculate Solar System Size For Your Home
A simple rule of thumb: 1 kW of rooftop solar generates roughly 120 kWh/month in India and 130 kWh/month in the US sunbelt. Divide your monthly consumption by that number to get the kW size, then add 10–15% headroom for cloudy weeks and future EV charging.
Solar Subsidy Calculator – USA & India
In India, PM Surya Ghar Yojana pays ₹30,000/kW up to 2 kW and ₹18,000/kW for the third — capped at ₹78,000 for residential rooftop. In the USA, the Federal Solar Investment Tax Credit (ITC) cuts 30% off your total installed cost, with additional state and utility rebates available in California, New York, Massachusetts, and others.
Solar Loan EMI Calculator
Indian PSU banks offer solar loans at 8–12% under the PM Surya Ghar scheme. In the US, solar lenders typically price between 6–10% APR. A 5–7 year tenure keeps EMIs close to your current electricity bill — meaning the system pays for itself month-on-month.
Best Solar Panels For House
In India, Waaree, Tata Power Solar, Adani, Vikram and Premier Energies lead on bankability and after-sales support. In the USA, Maxeon, REC, Qcells, Canadian Solar and Silfab are the most installed tier-1 brands for residential rooftop, with efficiencies of 21–24%.
