Belgium offers a 30% tax reduction on solar installation costs, with a maximum of €4,000 per household. This federal incentive applies to both equipment and installation costs, significantly reducing the upfront investment required for solar energy. The tax reduction can be claimed on your annual tax return in the year following installation.

Local Financing Options

In Antwerp, financing and incentives can differ by region (Flanders, Wallonia, Brussels). Start with your regional energy portal and local lenders that provide renovation or sustainability loans.

National Financing Programs

Across Belgium, combine regional support with national tax and housing-finance guidance where applicable. Compare fixed vs variable rates and verify whether battery additions are included in the loan scope.

Before You Apply

Prepare your latest electricity bills, roof information, and at least two installer proposals. Confirm whether the finance package includes batteries, electrical upgrades, and grid-connection costs, and ask how grants/rebates are applied in your cash-flow timeline.
