Solar photovoltaics

Electricity without waste, noise or harmful gases? You’ll love photovoltaics.

Photovoltaics (PV) is the direct conversion of solar energy into electricity by solar panels. The direct current is transformed by an inverter and fed into the grid. Two applications are possible. Grid-connected installations are connected to the public electricity grid, while island installations are stand-alone installations that produce electricity for own consumption. Objects that are far from the grid, e.g. mountain lodges, holiday homes, emergency stations and parking meters, are supplied with power by means of stand-alone PV systems with storage devices (batteries). This is known as island operation.

The solar systems are installed on roofs, facades or plots of land.

Solar thermal

Thermal solar collectors can be combined with any other heat generator. These systems are useful for heating domestic water or for supplementary heating. Most cantons and many municipalities support solar thermal systems, providing subsidies and tax deductions. Solar systems make you self-sufficient, so you are not bothered by rising energy prices. And since the introduction of the CO2 tax on fossil fuels, owners of solar systems have benefited twice over. The sun is reliable. In combination with other energy carriers, it provides a comfortable supply of heat and hot water all year round. Simple solar systems for hot water preparation can be installed in one to two days. The technology of a solar thermal system is very simple and does not require a large construction site.
