Photovoltaics

Solar panels have an average lifespan of 25 to 30 years. Many manufacturers also offer guarantees of up to 25 years on the performance of the photovoltaic modules, allowing you to benefit from your investment in the long term.

The installation and assembly of a solar system usually only takes a few days. The exact duration depends on the size of the system and the individual conditions on site.

The electricity production of a solar system depends on various factors, such as the size of the system, the geographical location, the orientation and inclination of the panels, the efficiency and the strength of the solar radiation. An average solar system for a single-family home can generate around 4,000 to 6,000 kWh per year, which can often cover a household's entire annual requirements.

The cost of solar panels varies depending on the size of the system, the technology used and the individual installation conditions. A typical system for a single-family home can cost between 5,000 and 15,000 euros. However, there are numerous subsidy options that can significantly reduce the purchase costs.

Complete self-sufficiency is difficult to achieve, but the solar panels can cover a large part of your energy requirements. With additional storage solutions, such as battery systems, you can store and use surplus electricity when the sun is not shining, further increasing your independence.

Yes, solar panels can be installed on almost all types of roofs, including flat roofs and even on a motorhome to have solar power when camping. With special mounting systems, the panels can be aligned at an optimal angle to make the most of the sun's rays.
