Photovoltaics in Switzerland was expanded significantly in the past year 2020. According to a press release, according to the Swiss Association for Solar Energy, this was not enough to achieve the climate targets. The professional association Swissolar represents the interests of 740 association members with around 6000 jobs in the solar energy industry. In the announcement from Swissolar, the additional photovoltaic capacity installed in 2020 is estimated at an output of 430 to 460 megawatts. The final annual figures will not be available until the middle of the year.
The new installations correspond to a growth of 30 to 39 percent compared to 2019. According to Swissolar, the number of registrations at the Pronovo certification and funding agency suggests that the growth not only occurred in small systems, but also in those with an output of over 100 kilowatts.
From the point of view of the association, however, more needs to be done. "In order to replace the nuclear power that is no longer available and to cover the additional electricity demand for the electrification of traffic and heating, the annual expansion must be increased to around 1500 megawatts over the next few years – almost four times as much as last year," said Swissolar CEO David Stickelberger quoted. This is also provided for in the recently published Energy Perspectives 2050+ by the Federal Office of Energy.
From the perspective of the solar industry, a number of political measures are required to achieve this. Greater support for systems without self-consumption is therefore necessary. This requires state incentives so that the roofs of stables, warehouses, parking lot canopies, noise barriers and other infrastructures are equipped with solar systems. Often this is not the case because the electricity cannot be consumed on the spot. Further measures are the obligation to generate electricity for new buildings, the removal of hurdles in the construction of open-space systems, which often only get a building permit with difficulty.
From Swissolar's point of view, there is also a need for federal and cantonal funding for solar thermal systems. The contribution of solar heating to the energy transition is still underestimated.
