How accurate is the Varka solar ROI calculator?

Our calculator uses PVGIS irradiance data calibrated for Delhi-NCR (1,500-1,600 kWh/kWp/year), current DISCOM tariff data, and live subsidy rates. Results are within 5% of actual system performance.

What data do I need to use the calculator?

You need your monthly electricity bill amount, approximate rooftop area, and your city. Optionally, your sanctioned load and panel orientation improve accuracy.

Does the calculator account for subsidy?

Yes. The PM Surya Ghar central subsidy and applicable state subsidies are automatically deducted from the system cost based on your selected system size.
