IEA PVPS Task 1 has published the National Survey Report of PV Power Applications in Belgium 2024. The report provides an overview of PV market development, policy frameworks, system prices, industry structure, and the role of PV in Belgium’s energy system during 2024.
Belgium strengthened its position as one of Europe’s leading solar markets in 2024, reaching 11.7 GW of cumulative installed PV capacity by the end of the year. Solar PV generated 8.32 TWh of electricity, covering at least 10% of total national electricity consumption.
Following a record year in 2023, when around 2.5 GW of new PV capacity was installed, at least 0.98 GW of new installations were recorded in 2024. Based on historical reporting revisions, total additions for 2024 are provisionally estimated at around 1.4 GW. With a population of approximately 11.7 million inhabitants, Belgium reached a per capita PV capacity of 994 W, ranking among the leading countries globally.
The Belgian PV market remains dominated by small-scale residential systems below 10 kW, while commercial, industrial and utility-scale segments continue to expand. In 2024, the average turnkey price for residential building-applied PV systems in the 5–10 kW range stood at 1.25 €/W (including VAT). The report also notes the authorisation of balcony PV systems since April 2024, expanding access to PV for tenants and households without suitable roof space.
Solar PV continued to outpace onshore wind in annual capacity additions, further strengthening its role in Belgium’s electricity mix. Reported generation figures do not include self-consumed electricity, meaning the total contribution of PV is higher than grid-injected values alone suggest.
Belgium’s PV manufacturing sector remains limited but is evolving. In 2024, Belga Solar commissioned a new 50 MW production line, and plans for a 500 MW module assembly plant in Wallonia could significantly increase domestic manufacturing capacity. Belgium also maintains strong research and innovation activities across the PV value chain, including high-efficiency tandem and perovskite cells, building-integrated PV, floating PV, and sustainability-related topics.
