Norway installed 117 MW of solar in 2025, according to figures published by the Norwegian Water Resources and Energy Directorate (NVE).
The result is down on both 2024’s result and the country’s record year for solar deployment in 2023, taking cumulative capacity to around 876 MW.
The commercial and industrial market segment added the majority of Norway’s solar in 2025, installing 81 MW across the commercial and institutional and other services sectors, as defined by NVE.
Hassan Gholami, a senior consultant on solar and storage at Multiconsult, told pv magazine that the main market driver last year was commercial actors seeking energy independence and cost savings amid moderately high daytime power prices.
In contrast the residential market, once the dominant segment in Norway’s solar mix, added 13 MW in 2025. Gholami said this downturn was strongly influenced by lower spot prices, reduced subsidies and economic uncertainty.
“High interest rates, among the highest in Europe, also made many projects less appealing, especially for households and small to medium-sized enterprises,” Gholami explained, before adding that 2025 was also marked by a wave of bankruptcies and layoffs in the sector, with firms scaling back operations, in turn eroding confidence and reducing market capacity.
Residential demand has also been impacted by the Norgespris scheme, a capped household electricity price introduced last year.
