Funding for solar installations
How are solar installations funded?
Nowadays, a photovoltaic system can be installed on a small roof of a detached house for as little as CHF 10,000 (incl. subsidies & tax savings). This is an approximate amount, as various factors influence the price of the photovoltaic system.
The costs of a solar installation mainly depend on the following factors: roof size and performance, choice of solar modules, material costs (inverter + substructure) and scaffolding incl. fuse box.
The net investment costs for the photovoltaic system are greatly reduced by subsidies. Depending on the canton, the subsidies can amount to several thousand francs. Helion takes care of all registrations and applications so that you also receive the maximum possible subsidies.
Roof size | Occupant | Costs per m² in CHF | Costs for solar panels in CHF |
ca. 25 m² | ![]() |
ca. CHF 780.- | CHF 19’500.- (incl. subsidies & tax savings) |
ca. 40 m² | ![]() |
ca. CHF 550.- | CHF 22’000.- (incl. subsidies & tax savings) |
ca. 60 m² | ![]() |
ca. CHF 434.- | CHF 26’000.- (incl. subsidies & tax savings) |
Purchase costs per household after 30 % deduction of the subsidy & 25 % tax saving.
In addition to the surface area, the costs incurred for a solar installation depend above all on the power (kWp). Even at the time of purchase, the power of the solar modules can vary by up to 20 %.
A battery storage device and a heat pump can be used to supplement a photovoltaic system. With these two additional components, the self-consumption of a block of flats or a detached house can be significantly increased – and thus the use of the solar panels optimised.

Due to the high demand for photovoltaic systems, there has been plenty of movement in the solar market in recent years. Why is now the best time to buy a solar installation?
![]() |
Photovoltaic systems currently cost just 20 % of the price you would have paid ten years ago. At the same time, subsidies are decreasing year on year. |
However, the authorities are reaching their financial limits due to the high demand, which means that the subsidies for solar installations are decreasing every year.
The best and most favourable time to buy a solar panel system is therefore right now. The longer you wait, the fewer subsidies will be available to you.
