Photovoltaic, sales fall: "We need investment security" (cross-border guide)

Context

In a nutshell

• Sales of solar panels in Switzerland decreased by 30% in 2025.
• The Federal Office of Energy recorded a decline in sales of photovoltaic systems in 2025.

Key facts

• What: Sales of solar panels in Switzerland have declined.
• When: In 2025.
• Where: In Switzerland.
• Who: The Federal Office of Energy.
• Amount: 30%.

Sales of solar panels in Switzerland fell by 30% in 2025, according to the Federal Office of Energy. The uncertainty also weighs on the customers of Walter Sachs, an energy consultant who chairs the association of independent energy producers.

“The decline in solar panel sales is a warning sign for the energy sector in Switzerland,” says Walter Sachs. “Lack of investment security is a serious issue that needs to be addressed urgently.”

According to data from the Federal Office of Energy, sales of solar panels in Switzerland fell by 30% in 2025. This decline is partly due to the global energy crisis and the lack of incentives for renewable energy production.

“Switzerland is a leading country in the production of renewable energy, but the decline in sales of solar panels is a warning sign for the future of the sector,” says the director of the Federal Office of Energy.

Photovoltaic, sales fall: "We need investment security"

Declining sales of solar panels in Switzerland is a serious problem for the energy industry. Uncertainty over tariff rates and a lack of security for investments are the main causes of this decline. Walter Sachs, an energy consultant, says you need security for energy investments. The Federal Office of Energy recorded a decline in sales of photovoltaic systems in 2025.

According to data from the Federal Office of Energy, sales of photovoltaic systems decreased by 20% in 2025 compared to the same period of the previous year. This decline is mainly due to uncertainty about tariff rates for electricity produced from renewable sources. Switzerland introduced a tariff system for electricity produced from renewable sources in 2020, but energy policy has changed several times in recent years, creating uncertainty among investors.

The canton of Bern is one of the main markets for photovoltaic systems in Switzerland. In 2020, the canton of Bern approved a renewable energy development plan, which envisages the construction of 100 MW of photovoltaic plants by 2025. However, in 2022, the canton of Bern announced a two-year delay in the renewable energy development plan, creating uncertainty among investors.

Key points

Photovoltaic, sales fall: "We need investment security"

The Swiss photovoltaic industry is going through a difficult period, with sales falling and photovoltaic plants failing to cover production costs. To overcome this problem, it is necessary to increase security for investments in the energy sector. The Federal Office of Energy must do more to promote photovoltaic systems and ensure a higher one-off remuneration for those who build a photovoltaic system. In addition, it is necessary to create a more understandable and stable system to cover investments.

According to data from the Federal Office of Energy, 444 photovoltaic plants were installed in Switzerland in 2020, with a total capacity of 444 MW. However, in 2022, the number of installed plants dropped to 233, with a total capacity of 233 MW. This decline is due to several factors, including the global energy crisis and competition with cheaper renewable energy sources.

To solve this problem, it is necessary to create a more stable and understandable support system for photovoltaic systems. For example, the Canton of Ticino has implemented a support system for photovoltaic systems, which provides for a single remuneration of 0.10 CHF/kWh for the first 10 years of operation of the plant. This system has made it possible to increase the spread of photovoltaic systems in the
