Estimate your system size and savings

Enter your average monthly electricity bill to get an estimated capacity, generation and payback range. This runs entirely in your browser — nothing is sent anywhere.

Not sure? Check a recent bill — 7 to 9 per unit is typical for Rajasthan domestic connections.

Used only to cap the estimate if your roof is small. Leave blank if unsure.
