how this is calculated

The maths behind your estimate

Final numbers are always confirmed after a free site visit, but here's exactly what the calculator above is doing.

1. System size

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.

2. Subsidy

₹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.

3. Payback & ROI

Net investment (cost minus subsidy) divided by annual savings gives payback period. 25-year ROI accounts for panel degradation and assumes stable tariffs.
