Solar Energy Services
If you would like to invest in your own solar power plant or you would like to lease your land to RGE in order to operate a solar plant on your property at no own cost - you can benefit from financial support. Depending on the size of the installation, this is either the feed-in-tariff (FIT), or in case of larger installations, the renewable obligation certificate (ROC) regime. In addition, you can use some or all of the generated electricty on your property.
With RGE everything from planning to turn-key installation and monitoring comes from one source. Our experts have delivered time and time again the highest quality solar power plants, and we can offer you a smooth project development.
The most important component of the plant is the module. A module consists of several interlinked cells, which generate electricity from sunlight. Modules fall into two general categories:
Crystalline modules have a high efficiency and achieve the highest yields when positioned with an inclination between 30 to 35° facing southward and when a good rear-ventilation is available.
Thin film modules achieve attractive yields even at sites with less favorable irradiation conditions and roofs with sub-optimal orientation. Therefore they increase the potential locations where they can be used.
The inverter is responsible for converting the DC current from the modules to alternating current, so that the electricity can be fed into the public electricity grid.
The selection of the right inverter - suitable to the whole PV-system - is crucial, as the efficiency of this component determines how much of the electricity from the modules can actually be fed into the grid.
The monitoring system controls the solar power plant on a 24 hour basis. An alarm system informs you in case of disruptions. This makes it possible to correct failures immediately and minimize the loss of earnings.
4. Solar- and Two-way-meter
The electricity meter measures the amount of power that is fed into the public grid. The consumption meter informs you how much power the household obtains from the public grid. If you want to use your solar energy yourself you need an additional solar meter, which measures the amount of electricity that is produced by your solar power plant. The difference between the electricity and solar meter shows how much of the produced solar energy is used in your own household. Electricity meter and the consumption meter can be combined in a so called 'two-way-meter' or 'net meter.'
