The solar field Erlasee even solar Gut Erlasee , is between 2005 and 2006 on the former estate Frankish Erlasee at Arnstein in the district of Main-Spessart ( Bavaria built) solar power plant . Until the beginning of 2008, the system was the largest photovoltaic open space system in the world.

General

The solar park is a joint project of the Berlin solar module manufacturer Solon SE , the project planning and sales company SAG Solarstrom AG and E.ON Bayern AG, into whose 20 kV network the electrical energy generated is fed into the village of Schönarts, about eleven kilometers to the west .

After a construction period of 15 months, the solar field was ceremoniously put into operation on September 1, 2006 with a concert by BAP and The BossHoss . The entire project cost around 70 million euros. The total of 1,464 trackable solar modules were "commercialized" in various ways.

technology

On the 85 hectare site, 1,464 solar modules that track the sun on two axes convert sunlight into electrical energy under standard test conditions of 11.4  MW ( watt peak ). Around 14 GWh are generated per year  , which corresponds to an actually achieved average output of 1.6 MW, the capacity factor is 13%. To track the solar modules, twelve modules are mounted on movable substructures, so-called movers. With this technology of the SOLON Mover, the initiator of the park expects an additional yield of around 30 percent. Solar modules that are around 1.55 meters wide and 2.6 meters long are used. Modules with one type of solar cell are always used per mover ; modules with both polycrystalline and monocrystalline cells with efficiencies between 15 and 22 percent are installed in the entire solar field.

Space requirement

The space requirement is around 74,500 m² per MW peak and is more than twice as high as for a system that is strictly south-facing. The reason is that the modules of this tracking system also need free space to the east and west so that there is no mutual shadowing when the sun is low. The advantage of this construction method is an approximately 30% higher normal working capacity (energy yield per module) and the better agricultural usability of the soil compared to a rigid, south-facing installation.
