Biel, Switzerland [RenewableEnergyWorld.com] Spanish company Vasolar 2006 S.L. and its Portuguese business partner Cavalum SGPS, S.A. announced that they have inaugurated four solar parks delivering a total output of 8 megawatts in Extremadura, Spain. The tracking systems have the potential to produce a total of 26 gigawatt-hours of energy per year on average.
Valsolar and Cavalum are set to receive the higher Spanish feed-in tariff guaranteed by royal decree RD 661/2007 for solar installations commissioned before the end of September. The decree guarantees a higher payment for installations of up to 100 kilowatts.
Valsolar and Cavalum have therefore divided the four solar parks into smaller systems, each with an output of 100 kilowatts. They receive €0.4551 [US $0.665] for each kilowatt-hour fed into the grid. The four solar parks represent a total cost of €40 million [US $58.45 million]. Valsolar said that it expects a payback period of approximately 10 years.
Valsolar and Cavalum chose to install Sputnik Engineering’s 100-kilowatt central inverters for the projects. In 2008 alone the company has so far installed 70 SolarMax inverters.
