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]
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.
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.

The general rule of thumb is that a 100-watt solar panel can produce about 30 amp-hours per day, so you can use this guideline to determine about how many panels you need. Another suggestion is to match your battery capacity in amp-hours with your solar output in watts.. The general rule of thumb is that a 100-watt solar panel can produce about 30 amp-hours per day, so you can use this guideline to determine about how many panels you need. Another suggestion is to match your battery capacity in amp-hours with your solar output in watts.. The size of solar panel you will need for your RV battery will depend on battery capacity, panel efficiency and energy use per day. At a minimum, you will likely need at least two panels of 100 watts each. [pdf]
