"The Mk-I HCPV panel design is highly cost effective and concentrates light from the sun more than 500 times," Pico said. "This product has conversion efficiency up to twice that of silicon flat plate solar panels and more than three times that of thin film solar panels, making it the optimum solution for solar grid field installations," he said. "The use of OPEL's energy efficient panels together with Spain's feed-in tariff structure allows attractive rates of returns for solar projects."

"We at BETASOL are very pleased to expand our partnership with OPEL, one of the leading HCPV suppliers in the world," said Jesus Cabetas, Managing Director of BETASOL. "OPEL's outstanding panel efficiency allows for increased investor interest and attractive rates of returns on our Spanish solar projects."

OPEL previously announced the shipment of its Mk-I HCPV panels for the first BETASOL installation. Shipment began in December 2008, and is scheduled for completion in the second quarter of 2009.
