As of 1 January 2007, a new Decree provides various subsidies for the installation of solar energy in households. For these small photovoltaic systems, the Brussels government offers a subsidy of EUR 3 per peak watt with a maximum grant of 50 % of investment cost per household (40% for professional sector, such as industry or services), with a maximum grant of EUR 3000 for solar water heating systems and EUR 6000 for combination systems for solar water heating and central heating. In addition, the cost of a meter is reimbursed (EUR 235). IEA/IRENA Global Renewable Energy Policies and Measures Database © OECD/IEA and IRENA, [November 2020]
