Me the Photovoltaic system You generate your own private electricity – uncomplicated, cost-efficient and independent of the grid. Whether on your house, outbuilding or garage roof, old building or new building, buildings, for Carports or balcony systems.

Solar power with your own Photovoltaic system Producing solar panels has been a trend for years, because in combination with an electricity storage system it is possible to reduce energy costs in single-family homes by up to 80 percent.

How does a photovoltaic system work?

The Photovoltaic system (PV system) converts solar energy into electrical energy using the photovoltaic effect. The solar modules feed in the solar energy and generate direct current, which is then converted into alternating current (230V). The self-produced Photovoltaic electricity can be used immediately in your own household and stored in an electricity storage unit or fed into the public electricity grid for 8.0 cents as a refund.

How big should the solar system be?

An optimal size of the Photovoltaic system depends primarily on electricity consumption or the energy required. Ideally, the power plant should supply at least enough electricity throughout the year to cover your own annual consumption. This is based on the last electricity bill for your previous consumption. If you want to replace your old gas or oil heating with a heat pump or purchase an electric car, you should be able to use the entire sunny roof area!

How much electricity does a photovoltaic system produce?

The potential annual performance of a Photovoltaic system is expressed in kilowatt hours per kilowatt peak per year (kWh/kWp/a). A typical photovoltaic module measures approximately 1.1 m x 1.75 m (= 2 m²) and has an output of 450 Wp. One kilowatt peak (1 kWp), or approximately two modules, produces 900–1,100 kWh per year. Put simply: 1 m² of module area produces approximately 500–600 kWh per year.
