A complete installation costs on average € 4,000 to € 12,000, mainly depending on the number of panels. Expanding an existing installation costs € 1,500 to € 4,000, replacing an inverter € 800-2,000 and preparing a home-battery connection € 350-900. The roof type, cable route and inverter choice determine where you land in the band.

The net-metering scheme is being phased out and some energy suppliers charge fees for electricity fed back to the grid. That makes self-consumption more important: the more of your generation you use directly, the better the sums work out. Panels still pay off, but the payback period differs per situation — have the installer run the numbers on your consumption and roof rather than a rule of thumb.

Yes. On a flat roof the panels sit in ballast frames held in place by weight, without piercing the roof. You choose the tilt angle yourself and an east-west layout often uses the surface best. On a pitched roof the panels go on hooks and rails under the tiles. You state the roof type in the request, so the quote is right straight away.

That depends on your yearly consumption, the available roof surface and the roof's orientation. In the request, state roughly how many panels you want — or choose 'advice wanted', and the installer will calculate it based on your consumption and your roof.
