Tell us your state, average monthly bill and sanctioned load — we'll estimate the right system size, subsidy, payback period and 25-year ROI.
Your recommended system size, cost, subsidy and payback period will appear here.
how this is calculated
Final numbers are always confirmed after a free site visit, but here's exactly what the calculator above is doing.
We convert your bill into monthly units using your state's average tariff, then size a system that can generate that much power — capped at your sanctioned load — and round to our nearest standard kit size.
₹30,000/kW for the first 2 kW, ₹18,000 for the 3rd kW, capped at ₹78,000 — plus Delhi's ₹30,000 state top-up where it applies.
Net investment (cost minus subsidy) divided by annual savings gives payback period. 25-year ROI accounts for panel degradation and assumes stable tariffs.
