Frequently asked questions
How much does a rooftop solar system cost in Haryana?
A 3 kW system costs about ₹1,65,000.00 before subsidy in our estimate, dropping to ₹87,000.00 after the PM Surya Ghar central subsidy. Actual installer quotes vary by panel type, roof condition and local installation costs.
Does this use UHBVN's real tariff?
Yes — savings are computed against UHBVN's actual telescopic slab tariff, so solar is valued at offsetting your real, most expensive units first, not a flat national average rate.
What subsidy is available?
PM Surya Ghar: Muft Bijli Yojana, the central government scheme, pays ₹30,000/kW for the first 2 kW and ₹18,000 for the 3rd kW, capped at ₹78,000 — the same nationwide, regardless of state.
