Solar savings calculator
Run the numbers before you share yours.
Three short steps. The estimate updates as you type, and we do not ask for your name or phone. What the system costs comes from a survey, not a form.
Your estimate
Indicative estimateWe picked on-grid based on your backup answer. Change the system type in step 3 to compare.
- No PIN code yet, so this uses a national planning average for generation. Add your PIN code for a regional figure — it can move the estimate by 15% either way.
What the system costs
We do not price systems from a form. What an installation costs depends on the roof structure, cable runs, access and the condition of your existing panel — none of which a calculator can see, and all of which a surveyor can.
This configuration is eligible for PM Surya Ghar: Muft Bijli Yojana. The assistance is calculated against your installed cost, so the amount appears in your quotation alongside the price it applies to.

On these assumptions the system keeps about ₹15.8 L off your electricity bills over 25 years. That is bill savings only — the cost of the system is not netted off, because this calculator does not price it. The first five years are the dependable part.
