How does the comparison work?
You describe your roof and your consumption. Up to 3 registered installers send you their quote with the same sections (price per kWp, panels, inverter, battery, warranties, legalisation), and you see them side by side. You decide whether to go ahead and with whom.
What is the "price per kWp"?
It is the total price of the quote divided by the peak power of the panels (kWp). It helps to compare offers of different sizes, but it does not tell the whole story: also look at which inverter, battery, warranties and legalisation each one includes.
Are there IBI or ICIO tax rebates?
Some town councils grant them and others do not; the conditions are in your municipality's tax ordinance. Check it on your town council's website. We only show official sources, with their date.
