Enter module efficiency (%), total panel area, and price per kWh. The annual resource number is the PVGIS field H(i)_y in kWh/m² per year (same meaning as the «peak sun hours per year» input); use the table or city preset below. STC (1000 W/m²): annual energy per m² = H(i)_y × (efficiency ÷ 100).

Figures are the annual in-plane global irradiation H(i)_y (kWh/m² per year) from the European Commission Joint Research Centre PVGIS v.5.2 API (tool PVcalc, fixed mounting, optimal slope and azimuth, radiation database PVGIS-SARAH2, period 2005–2020). City coordinates are representative centres; values are rounded to the nearest integer. Official PVGIS: https://joint-research-centre.ec.europa.eu/pvgis
