SolFocus CPV Systems

Delivering on the Promise of Clean, Low-Cost Solar Energy

SolFocus' leading CPV technology combines high-efficiency solar cells with advanced concentrating optics to provide high energy yield using just 1/1000th the amount of solar cell material used in traditional photovoltaic systems.

CPV Power Unit

SolFocus systems utilize a reflective design which includes a primary mirror to capture sunlight, along with a secondary mirror and non-imaging optical system to concentrate sunlight 650 times onto high-efficiency III-V solar cells.

SolFocus Technology Highlights

By concentrating sunlight using innovative optics onto a small area of high-efficiency solar cell material, SolFocus systems dramatically reduce the amount of expensive and often supply-constrained solar material used in the system. Learn more about SolFocus technology by selecting the components below.

CPV Power Unit

  • All-glass optics for durability
  • Low optical losses for high efficiency
  • Wide acceptance angle for high yield and lower cost
  • Designed to avoid chromatic aberrations and cell mismatching
  • High efficiency cells approaching 40% efficiency compared to 13-19% efficiency for silicon PV cells
  • 1 cm2 cell per unit results in use of 1/1000th the solar cell material as used in traditional silicon PV systems
  • Robust cell design, originally designed for the demanding environment of satellites in space
  • High performance at high temperatures – not impacted by temperature degradation as are silicon PV cells

“The theoretical performance and cost advantages of CPV have been known for many years, but the key was moving the technology out of the research phase and into commercialization. SolFocus has made this big leap and is now delivering on CPV's long-term promise of large-scale, clean, affordable, renewable energy.”
