3-MW Solar Park in Spain Starts Production

Swiss solar inverter manufacturer Sputnik Engineering AG and solar systems supplier Wurth Solergy have officially started electricity production at one of the world’s largest systems that uses modules made of copper-indium-diselinide (CIS) in Albacete, Spain. The system, which consists of 41,600 solar modules and 100-kilowatt centralized inverters generates a total of 3.26 megawatts of electricity.

Fotovoltaica del Peral S.L., which operates the system, estimates an annual yield of 1,607 kilowatt-hours per installed kilowatt thanks to the high-quality components. The first long-term trial of this system has already produced a performance ratio of 82 percent, Wurth Solergy said.

“We are convinced that solar electricity units with our inverters will continue to pay their way even with reduced tariffs for supplying the grid,” said Christoph von Bergen, Sputnik’s managing director.

Compared with standard solar modules made of crystalline silicon, CIS modules have a better temperature coefficient, that is the module output falls off less steeply at higher operating temperatures. Sputnik Engineering said that higher temperatures don’t effect its inverters either. The system is capable of feeding at its full nominal output to the public grid even with ambient temperatures of up to 45°C.
