2.0Industry Overview
Solar installers plan and build photovoltaic systems on homes, commercial buildings and farms, increasingly with home batteries, heat pumps and charging stations. After four boom years the market turned in 2025. According to the federal solar statistics, compiled by Swissolar for the Federal Office of Energy, 1,333 MW of new capacity was installed in 2025, 25.9% less than the 1,799 MW of 2024 and the first decline since 2017; module sales fell 29.3%. The installed base still grew 16.3% to 9,499 MW on 338,270 grid-connected systems, and solar output rose a third to 7,948 GWh, covering 13.7% of Swiss electricity consumption. Batteries moved the other way: lithium-ion storage sales rose 70.5% to 490,070 kWh.

9.0Frequently Asked Questions
▶How much is a solar installation company worth in Switzerland?
ValIndex's multiples table puts Swiss solar installation at 5.5–8.5× EBITDA in transactions and 4.0–6.0× EBITDA on statutory valuations. Firms with a qualified team, commercial projects, a service base and battery and heat-pump know-how sit at the upper end; small firms that grew only on the home-roof boom sit lower.
▶What drives the value of a Swiss solar installer?
Buyers price: (1) the installation team and its qualifications; (2) the pipeline of commercial and industrial projects; (3) the installed base and service contracts; (4) battery and heat-pump know-how; (5) supplier terms and stock; (6) dependence on the owner.
▶How big is the Swiss solar market?
At the end of 2025 Switzerland had 9,499 MW of PV capacity on 338,270 grid-connected systems, producing 7,948 GWh, or 13.7% of electricity consumption. 1,333 MW was added in 2025 (BFE/Swissolar). Installers are not counted separately; most work in electrical installation (4,940 firms, 55,988 employees in 2024).
▶Who are the main solar companies in Switzerland?
Helion Energy (Cham, AMAG Group) is a large installer of solar systems, heat pumps and charging stations. Ernst Schweizer (Hedingen) makes mounting and in-roof systems. Meyer Burger (Thun), the former Swiss module maker, has been in a debt-restructuring moratorium since 2025. Most installations are built by regional installers.
▶What are the key trends in Swiss solar installation?
Five trends: (1) new capacity fell 25.9% in 2025, the first decline since 2017; (2) home-battery sales rose 70.5%; (3) solar reached 13.7% of electricity consumption; (4) commercial roofs took the most capacity; (5) new owners such as AMAG and the collapse of Meyer Burger.
▶What are the main risks when buying a Swiss solar installer?
The main risks are: (1) a further fall in volumes and prices; (2) stock and working-capital risk; (3) warranty claims on installed systems; (4) changes to tariffs and subsidies; (5) dependence on the owner and on a few installers. Due diligence should check the order book, margins per project, stock, warranties and staff qualifications.
