⚙️ Performance ratio
A user-selected factor represents approximate system, temperature, cabling and inverter losses.
🏠 Indicative only
Shading, dirt, inverter clipping, panel technology and actual installation geometry are not modelled.
Data sources and terms of use
Open‑Meteo Solar Forecast
Global tilted irradiance, cloud cover, sunshine duration and temperature.
e‑meteo calculation
Hourly irradiance is converted to an indicative kWh estimate using nominal kWp and the selected performance ratio.
