20 years ago the sun was the most expensive source of energy in the world. Today it is globally the cheapest form of energy. That’s because photovoltaics (PV) has evolved from a small niche market to a commercial mass market.
In a photovoltaic (PV) system, part of the solar radiation is converted into electrical energy using solar cells. So you can generate your electricity at home. Once installed, a PV system supplies free electricity for around 25 years. The variety of possible applications, for example on roofs or facades, as well as the low-maintenance operation make photovoltaics a form of energy with a great future.
Solar Power Generation System can be used to produce hot water and also to support heating. 50% of the solar energy is converted directly into warm water via the collectors. The technology is simple, durable, and reliable.
Generating your electricity makes sense for several reasons:
- Generate electricity cheaply yourself: electricity can be generated with a photovoltaic system at a lower kilowatt-hour price than electricity suppliers offer to their end customers. The difference is now around 20 cents and more per kilowatt-hour.
- With a newly installed photovoltaic system, solar power can still be freely consumed up to a certain output (30 kWp) without having to pay a financial fee. The usual system size for one- and two-family houses are 4 to 10 kWh, so their operators do not have to pay an EEG surcharge.
- A photovoltaic system increases the value of your own property.
- Generating your solar power protects the environment. During its operating time of around twenty years, a photovoltaic system generates more electricity than was used to produce all of the components.
