In 2021, Switzerland's photovoltaic (PV) installations increased to 685 MWp from 475 MWp in 2020. The Federal Energy Act, revised and effective from January 1, 2018, changed the support scheme for PV systems: it extended the one-time investment subsidy to all sizes of PV systems, ranging from 2 kW to 50 MW. Additionally, in 2022, the investment subsidy formula was updated to encourage investments in larger PV capacities and more efficient use of rooftop space. [pdf]
It is expected that solar PV power will continue to lead Switzerland’s power market in terms of cumulative installed capacity even in the year-end 2030. Solar PV power had the dominant share in the total renewable power installed capacity of Switzerland. This share is expected to further increase by 2030.
In 2024, the Swiss Solar Energy Association said solar power could be covering 50% of Switzerland's annual electricity consumption in 2050 if current market and installation trends continue.

In Switzerland, the price paid for solar energy added to the grid varies widely, ranging from less than 4 cents to as high as 21.75 cents per kWh in 2022 in one canton alone. In 2022, Switzerland derived 6% of its electricity from solar power.
The cumulative installed capacity for the solar photovoltaic (PV) market in Switzerland was 2,973.40 MW in 2020. It is expected to grow at a CAGR of more than 12% during the forecast period. Partnerships was the largest deal type in the market followed by asset transactions and equity offerings.

A Swiss start-up’s system to quickly install and remove solar panels between train tracks is now being tested. The "revolutionary" technology is attracting interest from other countries. I cover climate change and energy through reportages, articles, interviews and in-depth reports.
Typically, solar panels in Switzerland are mounted on existing infrastructure like mountain huts, ski lifts, and dams, with larger-scale installations in the Alps remaining rare. On September 10, 2023, 54% of Valais voters rejected Alpine solar project proposals due to environmental and aesthetic concerns.
Joseph Scuderi and his team now have three years to study whether a railway line can also serve as a solar power plant. If it can, the idea he had by chance at Renens train station could revolutionise the way the world produces solar power. Edited by Gabe Bullard/vdv
However, the Swiss start-up is the first to have designed a removable system that can be placed on railway lines that are open to traffic. By exploiting the vast unexploited surface along railways, Sun-Ways aims to “revolutionise photovoltaic energy production”.
Projects in Germany, Italy, France and Japan are testing solar panels between the rails. However, the Swiss start-up is the first to have designed a removable system that can be placed on railway lines that are open to traffic.

This paper explores how these containers address key site challenges: their rugged, forklift-friendly design (paired with 30–80 kW solar canopies) cuts diesel generator runtime by 55% (saving ~€5,940/month in fuel costs, per EREC 2025 data); smart load balancing supports peak tools like electric cranes while aligning with the EU Circular Economy Action Plan (reusable across 5+ projects); and a 3.2-year payback period (IEA 2025) plus eligibility for €72B EU JTM funding boosts contractor ROI.
