Cost: photovoltaic panel installation
Compare tax-inclusive cost before grants, identified equipment, mounting, access, connections and procedures. Separate battery and roof work. No local average or flat roof-type surcharge is established; comparable offers require the same project basis.
Editorial update on 18 September 2026
Break down installed cost
Separate modules, inverter, mounting, roof access, electrical work, installation and formalities. Clarify transport, protection and reinstatement. Ask about roofing and distribution-board exclusions before comparing totals.
Check VAT by item
Guichet states direct 3 % VAT for supply and installation of solar panels on private dwellings, outside the housing VAT concession. Distinguish ancillary items, especially storage, instead of applying the rate indiscriminately.
Compare options consistently
Request a battery-free base offer and separate options. Cost per kWp is useful only for equal scope. Include written warranties, support, repairs and replacement assumptions in lifetime-cost analysis. No payback or grant-payment period is guaranteed here.
