A solar power system is an investment that usually pays off and can generate profit over the entire service life of 30 years. Due to the increasing number of solar systems produced, prices are falling steadily.
An average single-family house in Switzerland has an annual electricity consumption of around 4,500 kilowatt hours (kWh). For a single family home, for example, a solar power system with an output of around 8 kilowatts peak (kWp) could be installed. An annual output of around 900 kWh is calculated per kWp. In this example, this would result in an annual electricity production of 7200 kWh per year.
The costs - before subsidies and tax benefits - for such a photovoltaic system in Switzerland amount to around CHF 20,000. PV systems are subsidized by the state, with a one-off payment being made for the purchase, which in this example is around CHF 4,000. With additional tax savings, the deductions add up to around CHF 5,000. Ultimately, the net investment costs in this example are CHF 15,000.
