Solar cost calculator
See the realistic cost range for your system size, how it splits across components, and whether the price in your offer is cheap, fair or expensive.
Data set
These are reference values for Europe. Our country sites carry verified local data: myosolar.de, myosolar.at, myosolar.ch, myosolar.it, myosolar.es, myosolar.fr
Your inputs
kWp
Total price including VAT and battery, if any.
Result
VAT is not included in this figure, because the rate is set nationally and ranges from 0 percent to 27 percent across Europe. Select your country to see the rate that applies.

German figure used as a European reference. Verified national ranges in August 2026 are materially wider: AT 1800 to 2500 EUR/kWp, ES 800 to 1400 EUR/kWp, CH 2400 to 3200 CHF/kWp, IT 1300 to 3500 EUR/kWp.
- Battery cost per kWh, lower end400 EUR/kWh
- Battery cost per kWh, upper end900 EUR/kWh
Rules that apply in your market
- These figures are European reference values, not the rules of a single country. Our country sites carry verified local data.
Frequently asked questions
- Is the price per kWp lower for a bigger system?
- Yes. Fixed cost items such as scaffolding, planning and the inverter are spread over more kWp, so the price per kWp usually falls as the system grows.
- Does the range include a battery?
- Only if you enter a battery size. Battery cost is calculated separately from the verified cost per usable kWh in your market.
- What should an offer contain?
- Module and inverter type, a yield estimate with its method, mounting system, electrical work, registration, and clear warranty terms for product and installation.
