RWE has commissioned a 44-megawatt solar farm in the Province of Guadalajara, close to Madrid. Casa Valdes is a ground-mounted photovoltaic plant and will be able to supply the equivalent of 30,000 Spanish homes with green electricity annually.RWE installed 97,740 bifacial high-performance modules at Casa Valdes on an area of about 97 hectares. The advantage of this approach is that the bifacial cells are embedded in a double-sided glass module by which the solar radiation can be absorbed from both sides – the front and the back of the module. This will help to increase production. RWE also uses these innovative modules for its solar construction projects Puerta del Sol (close to Casa Valdes) and Las Vaguadas (Badajoz province). A total of 54 MWac are being constructed at these two sites.
