The system has a peak output of 1000 kilo watts.
The direct current it generates - which thanks to its highly efficient modules amounts to around 90,000 kilo watt hours (kWh) per year - is fed into the DC mains supply of the Karlsruhe tram system. As part of a European pilot project, the operation of a photo-voltaic system is being tested which is directly connected to the power supply of the municipal transport system. This dispenses with the need for the conversion into AC current which is usually required when generating power from solar energy. As a result, this could be a simple and cheap method of using solar energy. |
