Solar Savings Calculator
Estimate how much rooftop solar could save you each month and over the long term based on your current electricity bill or monthly consumption.
Estimate your savings
Enter your monthly bill first. If you already know your monthly units consumed, add that too for a more direct estimate.
Use your average bill amount in rupees. This is the easiest starting point for a quick savings estimate.
If you know your monthly units from your bill, enter them here to improve accuracy.
Optional. Used to tune tariff assumptions when exact unit rate is not known.
Leave blank if you want the calculator to use a default tariff estimate.
Optional. Used to slightly tune the savings estimate.
How we estimated this
- If you entered monthly units, we use that directly; otherwise we estimate units from your electricity bill and tariff.
- We then estimate a solar system size that can offset a large share of your monthly usage using shared generation assumptions.
- Savings, subsidy, cost range, long-term projection, and payback are calculated from the centralized SolarVishwa assumptions inside the shared calculator framework.

What this means
This calculator estimates a practical solar system size from your bill or energy use, then applies shared generation, savings, subsidy, and cost assumptions to show how rooftop solar can affect your monthly and long-term economics.
