Concentrated solar power (CSP) panels use two different mirrors to focus about 500 times the energy from the sun before the light is directed onto small high efficient solar cell. This small cell got cheaper than big one…. -:), that’s the idea behind. To use pricey materiel sparignly and gain in overall cost. The vast majority of the system “over 95%” is maid either from aluminum or glass. It uses traditionally lowcost and materials
SolFocus Announces that their system is 25% Efficient. SolFocus integrates its CPV panels with its advanced tracking system that continuously aligns the solar array with direct sunlight throughout the day as the sun moves across the sky.
The tracking technology has been developed specifically for S panels, providing a highly integrated and performance-optimized system. The tracking capability of the SolFocus 1100S results in energy generation ideally matched to peak demand periods.
