About this calculator
How is the system size calculated?
From your monthly bill and your state's average tariff we estimate monthly units, then size the system using typical solar generation for your state, rounded to whole panels.
Is the subsidy amount final?
No. It applies the central (PM Surya Ghar) and state rules currently configured for residential rooftops. The final subsidy depends on the scheme, your DISCOM and the installed capacity.
Why is the price an estimate?
Prices vary by brand, roof and installer. The calculator uses typical market rates per kW; your installer's proposal will have the exact price.
