Solar roof planner — questions
How accurate is the roof area?
You trace the outline yourself on satellite imagery, so the flat footprint is measured precisely. We then multiply by your chosen pitch to get the true sloped surface and keep ~70% of it as usable (allowing for edge setbacks, vents and chimneys). It's a solid planning estimate; a surveyor confirms the final layout.
Where does the sun/output data come from?
Yearly output is modelled by PVGIS, the European Commission's photovoltaic geographical information system, using satellite-derived irradiance for your exact latitude and longitude, roof tilt and orientation, minus standard system losses.
Are the cost and savings figures reliable?
They're realistic order-of-magnitude estimates based on current typical installed prices, electricity prices and export tariffs for your country. Real quotes vary with your roof, hardware and installer — treat these as a starting point, not a quote.
Does solar still work on an east- or west-facing roof?
Yes. South is best, but east/west roofs typically deliver around 80–85% of a south roof and spread output across morning and evening, which can actually raise self-consumption. The tool adjusts output for whichever direction you pick.
Is it really free and private?
The estimate is completely free with no account. Your address is used only to show the map and compute your result. You choose whether to share contact details for installer quotes.
