The biggest solar farm in Thuringia stands on KRINNER ground screws and mounting system

Gotha  In the district of Gotha, at the heart of Thuringia, the biggest solar farm of the state was built in less than two months. The general contractor Enviromena commissioned Krinner Schraubfundamente GmbH with the supply and installation of 10,108 ground screws and 16,366 running meters of frames for the investor and module manufacturer Masdar PV. Before the turn of the year 2011/2012, numerous functional tests confirmed the system was generating power exactly as planned.

At a rated peak power of 11.7 megawatts (MWp), the Masdar PV modules built on former military area will generate 10.5 million kilowatt hours of solar electricity each year. That means the farm will produce enough electricity to supply some 2,500 four-person households. This will save 9,300 metric tons of CO2 emissions each year, which equates to the exhaust from over 4,000 medium-sized vehicles.

The new photovoltaic power plant employs both micromorphous and amorphous silicon modules from Masdar PV. That the farm was built so quickly and efficiently is due mainly to the 17,320 full-sized modules (2.6 x 2.2 m) it uses, which were produced using the latest micromorphous technology. These 5.7 m² modules, which deliver nearly two thirds of the farm’s 11.7 MW, are considerably larger than any other solar products in use. It was the size of these modules that allowed such an efficient installation, as evidenced by the very short assembly time of less than six weeks for the entire farm.

The project is the largest solar farm in Thuringia and the first large-area application of the new, high-efficiency, full-sized modules manufactured using micromorphous technology. Only with the efficient project management of KRINNER, as supplier and installer of the supporting frames, and coordination with the system integrator Enviromena could the module installation be completed so quickly and thereby contribute its share towards the region’s supply of electricity from renewable energies.
