Explore solar potential across Poland
Click your location (or search for an address) and instantly see how much energy your roof could generate per year, powered by PVGIS satellite data from the EU Joint Research Centre.
Production estimates: PVGIS v5.3 (EU Joint Research Centre), 35-degree south-facing roof, 14 percent system losses. Overlay: annual yield per kWp interpolated from a grid of PVGIS points. Comparison uses the calculator's default prices. Map: OpenStreetMap contributors.
About solar potential in Poland
Solar potential in Poland is higher than the climate suggests. Even in the least sunny regions, annual yield reaches roughly 950 kWh per kWp, and across the south it exceeds 1,150 kWh/kWp — on par with parts of Germany, where rooftop solar is widespread. The map above draws on the same PVGIS dataset that powers our ROI calculator.
Frequently asked questions
A typical installation yields about 950–1,150 kWh per year for each kWp of capacity, depending on location and shading. For a 6 kWp home system that's roughly 5,700–6,900 kWh a year — usually enough to cover most of an average household's consumption.
Yes, but the gap is smaller than people expect. The sunniest southern areas reach about 1,150 kWh/kWp while the coolest northern ones sit near 950 kWh/kWp — a spread of around 20 percent. Roof pitch, orientation and shading usually matter more than latitude alone.
From PVGIS v5.3 — the open database of the European Commission's Joint Research Centre, built on years of satellite measurements. It's the same model European institutions use to estimate photovoltaic yield.
The map shows production potential alone for a chosen spot. The calculator goes further: it factors in electricity prices, net-billing, installation and battery cost, and works out the payback period and 25-year NPV.
