Waldpolenz Solar Park, which is the world’s largest thin-film photovoltaic (PV) power system, was built by German developer and operator Juwi at a former military air base to the east of Leipzig in Germany. The solar power plant is a 40 MW solar power system using state-of-the-art thin film technology, and was fully operational by the end of 2008. 550,000 First Solar thin-film modules from cadmium telluride (CdTe) are being used, which supply about 40,000 MWh of electricity per year.

The installation is located in the Muldentalkreis district in the state of Saxony in eastern Germany, built on half of the location’s 220 hectares in the townships of Brandis and Bennewitz. The investment costs for the Waldpolenz solar park amount to some 130 million euro.

Waldpolenz Solar Park Power plants such at this make renewable energy more affordable for consumers. It is projected that electricity from this installation will be 20 - 40% cheaper than it is at present in Germany.
