Solar Power Calculator
Estimate your solar energy production in seconds. Enter your location and planned system capacity — we'll calculate your annual electricity output using real historical solar radiation data.
How It Works
01
Your Location
Enter your postal code and country / region. We look up your coordinates and retrieve 5 years of historical solar radiation data from weather archives.
02
Solar Potential
We calculate the average daily Peak Sun Hours (PSH) for your area — the equivalent number of hours per day at 1,000 W/m² solar irradiance.
03
Production Estimate
Using your system capacity, local PSH, and a 0.75 system efficiency factor, we estimate your annual, monthly, and daily energy production.
