From 2023, the VAT on solar panels will be reduced from 21 to 0%. On balance, the cost of solar panels will not be less, but because you no longer have to reclaim the VAT yourself, it saves a lot of hassle. If you had solar panels installed in 2022, you can still reclaim the VAT on solar panels. You do this by registering as an entrepreneur with the Tax and Customs Administration. Please note, you must reclaim the VAT within six months of the end of the calendar year in which you bought the panels.
