It's tough to set fixed prices for solar systems because each one is customized based on the project and needs. Costs depend mainly on how many solar panels are needed and their quality. Examining the pricing of rooftop systems and how to access financial assistance free-of-charge and with no obligation.

For a single-family residence equipped with a pitched roof located in a well-serviced area of Switzerland, the annual electricity consumption falls between 5,000 to 6,000 kilowatt hours (kWh). To satisfy this energy requirement, a photovoltaic (PV) system with a capacity of approximately 9 to 11 kilowatt peak (kWp) is necessary.
This setup is projected to yield between 8,100 to 9,900 kilowatt hours annually, given that each kilowatt peak is expected to produce about 900 kilowatt hours of electricity every year. This configuration ensures surplus energy production, which can be supplied back to the local electricity network. Generating extra electricity is advantageous, particularly for accommodating future additions such as an electric vehicle.
The cost of a PV system with a capacity of 9 to 11 kWp is approximately CHF 25,000 to CHF 30,000. The federal government and the cantons offer various funding programs to promote the use of solar energy. The most important funding programs for photovoltaics are the cost-covering remuneration for feed-in tariffs (KEV) and the investment contributions for solar power plants.
Talk to our ExpertsFor an average single-family home consuming 6,500 kWh (kilowatt hours) of energy, a rooftop system would require an output of 10 kWp (kilowatt peak), and the battery should store 6.5 kWh (kilowatt hours). Here's the cost breakdown:
| Solar PV system components | Descriptions | Price CHF (excl. VAT) | |
|---|---|---|---|
|
Photovoltaic modules | Solar panels, also known as modules, are essential for your clean energy setup. Different technologies are available, each with different costs and performance levels. For instance, thin film solar panels may cost less than crystalline silicon ones, but you'll need more rooftop space for the same energy output. | CHF 7,000 to 9,000 |
|
Inverter | The inverter changes the solar panel's DC power into usable AC power for your building. Its cost depends on where you place it—module, string, or system level. Module and string inverters can increase system output, while a central inverter is a cheaper option initially. | CHF 3,000 to 4,500 |
|
Mounting System | Mounting options ensure your panels stay securely attached to your home's roof or carport. The cost depends on your system's size (more panels = more mounting) and your roof's shape, slope, and preferred design. | CHF 2,000 to 3,000 |
|
Battery storage | A solar battery stores extra electricity generated by solar panels for later use. It helps you use solar power even when the sun isn't shining, reducing reliance on the grid and saving money on electricity bills. | 6.5 kWh x 1,090 CHF = 7,085.00 CHF |
| Costs for assembly and accessories | CHF 5,000 to 7,500 | ||
| Electrical Installation | CHF 1,500 to 2,500 | ||
| Photovoltaic system costs | CHF 18,000 to 37,000 | ||
| Deduction of one-off payment (federal and cantonal) | CHF 4,000 to 5,000 | ||
| Total costs before tax deduction | CHF 14,000 to 22,000 |
While almost all cantons promote solar heat, there is a one-off federal reimbursement for photovoltaics. Many communities have additional support programs. The website energiefranken.ch provides an overview of these funding offers. Tax deductions make building a solar system even more attractive.
