Hard data for your exact address — not a national average. We use the EU PVGIS satellite database (the same system installers use) to model a solar PV array on your home, then translate it into euro on your electricity bill.
Up to 3 vetted installers will be in touch to arrange your quotes. Your PVGIS estimate goes with the request, so the numbers they quote should line up with what you see here.
Tip: download the PDF report to keep your numbers handy when you talk to them.
