SolFocus announced its latest Concentrator Photovoltaic (CPV) system solution -- the SF-1100S-CPV-28. This new generation of its CPV technology achieves panel efficiencies of 25%, resulting in systems which produce the highest energy density and highest energy yield of photovoltaic systems available today. SolFocus customer EMPE Solar will use the SF-1100S in its recently announced 10 megawatt utility-scale project, planned to be the largest deployment of CPV technology in Europe.
The SF-1100S system combines high-efficiency solar cells (approaching 40%) and advanced optics to provide energy solutions which are scalable, dependable and capable of delivering on the promise of low-cost, clean, renewable energy. The company's CPV design employs a system of reflective optics to concentrate sunlight 500 times onto small, highly efficient solar cells. The SF-1100S uses approximately 1/1,000th of the active, expensive solar cell material compared to traditional photovoltaic panels. In addition, the cells used in SolFocus CPV systems have over twice the efficiency of traditional silicon cells accelerating the trajectory for solar energy to reach cost parity with fossil fuels. 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 integration with SolFocus' SF-1100 CPV panels, providing a highly integrated and performance-optimized system. The tracking capability of the SF-1000S results in energy generation which is an ideal match to peak demand periods.
