Grid Connected Solar Systems
The main characteristic of grid connected solar systems is their connection to the public power grid. The German government started with the Renewable Energy Sources Act (EEG since 1.4.2000) a series of successful programs for the commercial introduction of grid connected solar systems which receive global attention.
The core of each solar power plant is the solar generator consisting of several solar modules. The generated direct current (DC) is converted into alternating current (AC) by the inverter. This current is in conformity with the public power supply system.
Special mounting systems give your installation a secure hold in conditions of heavy snow and strong wind.
The components of a solar power plant are:
- Solar modules for converting sunlight into electricity
- Inverter for processing solar power in network quality
- Safety components for electrical safeguarding of the system
- AC meter for recording the output
- Mounting system for securing the modules on pitched roofs, flat roofs or in case of in-roof installations
In Germany, due to promotion by the EEG, the power generated by a grid-connected photovoltaic system can be completely or only partially fed into the public power grid. It is possible to use generated power for self-consumption and take advantage of the arrangement of the EEG, too. For this, a feed-in meter and a meter for self-consumption is being installed besides the electricity meter. They measure the power fed into the public grid and the power consumed.
