The sun – a unique source of energy

The sun's energy is (almost) limitless. Around 5 billion years will pass before its hydrogen supply is used up. And: Its energy potential is extremely high. The amount of energy reaching the earth is about 5,000 times higher than the current energy demand of the entire world population.

  • As an energy supplier, the sun is inexhaustible
  • Its energy is free
  • The sun is an environmentally friendly source of energy
  • It can be used worldwide

All about solar energy

The sun energy

Clean energy from space: The sun can be ideally used as a free energy source for sustainable electricity.

The environmental idea

Those who use solar power protect the environment and help to ensure that future generations can live on a healthier earth.

The nuclear exit...

... is supported trhough photovoltaics. Because it is the only solution to close the gap created by the nuclear exit.

The coal exit...

The exit is a settled deal. This provides security for climate protection and sustainability. The phase-out will reduce CO² emissions by one third.

The climate targets in Germany

Germany's climate targets are to reduce emissions by 20% until 2020 and up to 40% until 2030. Photovoltaics makes a decisive contribution to this.

The climate targets in Europe

Compared with 1990, greenhouse gas emissions have to be reduced by 55 percent until 2030. Renewable energy sources are to be increased to at least 32 percent of the total energy production.


Solar power - what do I need to know?

Photovoltaics systems use light from the sun - and diffuse light - to generate electricity that is fed directly into the public power grid. In the process, the solar modules mounted on the roof capture the light energy and convert it into electrical energy.

The direct solar power that is generated in that way reaches the inverter via the main line, where it is converted into alternating current - the type of electricity used in our public power network. The amount of electricity produced is continuously measured via a dedicated feed-in meter and the electric current is fed into the public grid. In the return flow, this electricity is also available for the producer itself.

With the Renewable Energy Sources Act (EEG) of April 1, 2000, the German government regulates the purchase and remuneration of electricity from renewable energy sources.
