What exactly is photovoltaics?

Photovoltaics is not to be confused with solar thermal energy. This rather refers to the transformation of solar energy into usable thermal energy. This can either be used to support heating systems and/or to heat water. Collectors are needed for solar thermal systems, in which a liquid, e.g. water, is heated up by the sun.

What do I require to generate solar power?

In order to generate solar power, a solar power system is needed, which can be mounted either on roofs, on the ground, or on facades.

What is a solar power system?

A solar power system consists of solar power modules, one or more inverters, as well as an according mounting system. Solar irradiation creates a direct current in the solar cells. The direct current is then transmitted to the inverter through the connection socket and is then transformed into grid-compatible alternating current. The produced solar power is fed in into the public grid and is compensated by the local grid operator per kilowatt hour. If the power is used domestically, the compensation is adapted accordingly.

What is a solar power module?

What is the useful life of solar power systems?

Photovoltaic systems of a good quality are hardly susceptible to errors and require little maintenance. Long-term studies show that solar modules can still produce solar power, even after 30 or 40 years. The German Renewable Energy Sources Act (EEG) guarantees a feed-in compensation for 20 years. Solar-Fabrik gives you a performance guaranty of 25 years for the modules.

Is there a guaranty?

Solar-Fabrik gives a product guaranty of 12 and a performance guaranty of 25 on their Premium modules. Inverters have a guaranty of 5 years; 10 years are also available optionally.

What exactly is the EEG (German Renewable Energy Sources Act)?

The Renewable Energy Sources Act (EEG) promotes the expansion of power and heat generation from renewable energies. The grid operators are obligated to pay you a certain amount for every produced kilowatt hour (kWh), e.g. from solar power. The height of the compensation depends on whether the power is fed in into the public grid or whether it is directly consumed by you. The determined amount decreases annually by a certain percentage (degression). In addition, you receive tax advantages, since you receive back the 19% VAT that you have to pay when purchasing the system. Furthermore, you can write off the acquisition costs. This currently offers you an annual return rate of 5-8%.

Does a solar power system in Germany pay off?

The radiation intensity in all of Germany is high enough to economically operate photovoltaic systems. In the South, the irradiation is especially high so that higher yields are to be expected than in the North.

Does my roof support the installation of a solar power system?

Where can I get detailed offers for Solar-Fabrik products?

If you are interested in a solar power system, please contact us. We will  forward your wish to one of our partner businesses in your region. Our partner will then provide you with all the necessary information.

What are the advantages of solar power compared to other forms of the renewable energies?

Each year, the sun radiates 3,000 times more energy onto the Earth than the entire human population uses. This means that unlimited and free solar energy will continue to be available in the future. Solar energy is available almost in all countries and can be used sensibly.

It also garners special sympathies since it is inexhaustible, safe, and absolutely emission-free. Its utilization decreases the dependence on expensive energy imports (oil, gas, coal, uranium). It also garners special sympathies since it is inexhaustible, safe, and absolutely emission-free. Furthermore, the Renewable Energy Sources Act (EEG) provides the legal basis for economically operating solar power systems.
