No subsidy is assumed anywhere — this uses only real satellite solar data plus the numbers you enter yourself.

Why no built-in subsidy?

Because guessing your country's rules would be worse than asking you.

Solar incentives vary enormously by country — and even by state, province, or utility within a country — and they change often. Rather than bake in a guess that might be wrong for your exact location, this tool uses only two things that are actually reliable everywhere: real satellite-measured solar irradiance for your exact coordinates, and the real numbers from your own electricity bill and local quotes. If you know a specific incentive applies to you, add it manually above.

01

Real local sunlight

NASA's 22-year satellite record for your exact coordinates — not a national average, not a guess.

02

Your real numbers

Your currency, your tariff, your local installer's price — not an assumption that might not apply where you live.

03

No hidden subsidy math

If an incentive applies to you, you add it. Nothing is silently assumed on your behalf.
