In 2024, Switzerland deployed approximately 1.78 GW of new PV systems, according to provisional figures from PV Association Swissolar.
This marks an increase of 1.64 GW in 2023 and 1.08 GW in 2022, making 2024 the strongest year on record for newly installed capacity.
Swissolar, however, said that this growth will continue in 2025 and 2026. It predicts annual additions of 1.51 GW and 1.56 GW respectively.
The association attributed the expected delay to temporary uncertainties about the New Electricity Act. The growth is expected to stabilize at the current level, since the Act introduces provisions for energy communities and virtual power plants.
The cumulative installed solar capacity of Switzerland reached 8 GW at the end of 2024 8 GW.
