Official statistics from the Netherlands show the drop in annual solar installations last year was larger than estimates indicated. Annual deployments are now forecast to stabilise around 1.3 GW through to 2028.
The Netherlands added 1.4 GW of solar capacity in 2025, according to figures published by the Netherlands Enterprise Agency (RVO).
The official figure is down on estimates which put Dutch solar additions at around 2 GW last year. It also represents a sharp downturn in installations compared to recent years, which reached 5.2 GW in 2023 and 3.3 GW in 2024.
The 1.4 GW takes cumulative solar capacity in the Netherlands to 29.4 GW. At the end of 2025, 43% of solar capacity in the Netherlands was located on the rooftops of homes, smaller commercial buildings and public buildings. The remaining 57% was made up of large rooftop arrays, as well as ground-mounted and floating PV installations.
RVO says solar energy supplied a total 25.8 TWh of electricity in 2025, accounting for 19.7% of total Dutch energy production. This made solar the third largest electricity source in the Netherlands, behind wind (24%) and fossil fuels (48%).
