Acciona installs a photovoltaic innovation hub in Chile

Spanish Acciona Energía SA has created an innovation center in its »El Romero« solar plant located in Atacama, Chile to test new photovoltaic technologies that will improve the efficiency and performance of solar energy facilities. The hub will focus on the mechanical and energy capacity of double-sided crystalline, split-cell and thin-film cadmium telluride (CdTe) technologies, all of them in the development phase. The solar modules have been produced by JA Solar and First Solar, and a variety of solar trackers will be used, manufactured by STI Nordland and Soltec.
The innovation center, in which two of the three tracker zones have already been installed, will have a power generation facility with an installed capacity of 492 kW consisting of 1,280 modules in three series of trackers connected to nine inverters. These will be assisted by other equipment to measure and monitor parameters such as incident and reflected solar radiation, ambient temperature or the production temperature of each kind of module, among others. The thin-film modules are made from semi-conductive materials as alternatives to conventional crystalline silicon –such as cadmium telluride- that reduce both manufacturing costs and their carbon footprint during their working life.
»El Romero« is one of the biggest photovoltaic plants owned and operated by Acciona, with a capacity of 246 MW. Part of its capacity will be used to supply Google’s data center in the country.
