Europe solar guide
Solar panel cost calculator Europe
Estimate European solar panel system cost, output, electricity savings, export value, payback period and number of panels needed.
Use the main calculator with your local currency, household electricity price, export tariff or feed-in rate, local peak sun hours and installed cost after incentives.
Open the solar panel cost calculatorEuropean assumptions to check
- Electricity price: use the household tariff you actually pay, including taxes if relevant.
- Export value: enter the feed-in tariff, net billing value or export payment used in your country.
- Installed cost: include grants, VAT treatment and subsidies only if you want them reflected in payback.
- Solar output: generation can differ substantially between northern, central and southern Europe.
- Self-consumption: daytime load, heat pumps, EV charging and batteries can improve the value of solar electricity.
How to use the calculator in Europe
European solar estimates need local inputs. Use EUR or your local currency, enter your household import electricity price, and enter the export payment that applies to excess generation. If your country uses grants, VAT reductions or other incentives, enter the installed cost after those benefits only when you want the payback result to reflect your out-of-pocket cost.
Start with the solar panel output calculator to test local sunlight assumptions. Then use the solar savings calculator to compare self-consumed power against exported power. For payback, use the solar payback calculator. The methodology page explains the formulas.
Why European solar payback varies
Solar economics in Europe vary because electricity prices, incentives, VAT rules, export payments, grid limits and sunlight levels differ. The calculator is designed to be flexible by letting users enter their own tariff and cost assumptions instead of forcing one model for every country.
Southern regions may have higher output, while northern regions may need more panels for the same annual generation. Roof orientation, shading, inverter losses, battery cost and future electricity prices can also change the result.
Europe solar calculator FAQs
What currency should I use?
Use EUR or your local currency. The calculator works as long as the installed cost, electricity price and export value use the same currency.
Should I include incentives?
Include incentives only if you want the result to show payback based on the reduced out-of-pocket cost. For a before-incentive comparison, enter the gross installed cost.
Why is export value separate from electricity price?
Self-used solar offsets the import price. Exported solar may be paid at a different feed-in or net billing rate, so the calculator keeps these values separate.
