Photovoltaics - clean energy for a better future. With a photovoltaic system you can convert solar energy into electricity. This technology is becoming more and more popular because it is environmentally friendly and cost-effective. Photovoltaic systems can be installed on the roof of a house or other property. The system consists of solar cells that convert light into energy. This is converted into grid electricity in an inverter, which can be used in your home or business. The solar system produces electricity even on cloudy days, but with less efficiency. Reitbauer Haustechnik offers high-quality photovoltaic systems with storage as a complete package or individual components at reasonable prices.
