Photovoltaic expansion is in its infancy

Bern, April 2021

The Association of Independent Energy Producers has created an online map showing the status of the expansion of photovoltaics in Switzerland. The map shows major differences between the individual cantons. However, nowhere is more than 5.6 percent of the potential used.

Photovoltaics should be next to the hydroelectric power to buttress a climate-friendly energy future, the association of independent power producers (writes Vese ) in a release . The specialist group of the Swiss Association for Solar Energy has developed an online map on which the development status of photovoltaics in the individual communities, districts or cantons is shown. The interactive map also optionally shows the nationwide status or the expansion of individual power plants.

VESE explains that the map shows a very heterogeneous picture of the state of photovoltaics. Depending on the canton, the installed capacity per inhabitant is up to five times higher or lower. The cantons of Appenzell Innerrhoden and Jura have the highest level of development with more than 600 watts of power per inhabitant. In contrast, in the canton of Zurich, only 134 watts of power per inhabitant have been installed so far.

This could not be due to a lack of space, explains VESE in the press release. Even the front-runner Appenzell Innerrhoden is only using its potential to an "infinitesimally small 5.2 percent". For VESE project manager Diego Fischer, the photovoltaic policy is more responsible. It is "a big patchwork in which the hot potato is pushed back and forth between the federal government, the cantons, the municipalities, the electricity companies and the investors, and in the end everyone is wondering why things are not moving faster".

In order to promote the expansion of photovoltaics, the cantons and municipalities have to make better use of the instruments available to them, says Fischer. Specifically, the VESE project manager addresses the remuneration of solar power fed in and subsidies to supplement one-off payments. Fischer wants to increase the expansion of photovoltaics on the roofs of rental properties through building regulations.
