Swissolar calls for a faster pace of solar expansion
Swissolar estimates that the expansion of solar systems in Switzerland should have reached a record in 2020. According to the association, however, the pace must be accelerated further so that the climate targets can be achieved. He initially sees great potential in the roofs and facades of buildings.

The expansion of solar systems in Switzerland in 2020 was around 30 to 39 percent higher than in the previous year and thus at a record level. That is at least the estimate of the Swissolar association based on the figures already available on the statistics for solar energy 2020, which will be published in July.
In a communication on the occasion of the National Photovoltaic Conference in Bern, Swisssolar points out that the pace of the expansion must be further accelerated. The Federal Council's Energy Perspectives 2050+ anticipate annual solar power production of 34 terawatt hours by 2050. Swissolar would even aim for 45 terawatt hours. However, the annual expansion for both goals must be increased by a factor of three to four compared to the previous year, according to Swissolar.
According to Swissolar, the framework conditions would also have to be optimized for a faster pace of expansion. According to the association's assessment, the expansion of photovoltaic systems in Switzerland will mainly take place on the roofs and facades of buildings. An evaluation by Swissolar shows that small and medium-sized systems of less than 150 square meters on the roofs of single and multi-family houses hold almost half of the “easily accessible” solar potential. The association therefore demands that investment security should be created for these systems as a priority. In the medium term, the winter production of electricity is likely to become increasingly important. According to the association, alpine solar systems in particular are likely to play an important role here.
