Estimates only, not financial advice. Solar uses average weather for your roof from PVGIS (European Commission, 2005–2023 ERA5 data); without it, solar is estimated from the sun’s path. The 3D house is illustrative. Electricity plans shown are examples, not real retail offers, so check your own plan’s prices. Map data © OpenStreetMap contributors.
