RayGen

About This Project

Due to the requirement of large quantities of both land and photovoltaic (PV) panels, current utility PV installations are very capital intensive.

 

RayGen is a proprietary breakthrough utility-scale solar energy technology that utilises a field of low cost heliostat collectors to concentrate sunlight onto an ultra-efficient multi-junction photovoltaic cell array, located in a mast mounted central receiver. The technology combines the benefits of traditional PV with solar thermal energy installations and leverages several patents and trade secrets.

 

Concentrated Solar Photovoltaic (CSPV) technology consists of two main components, the heliostats (collectors) and the receiver (converter). A heliostat is a glass mirror placed on a tracker, and the receiver contains a ‘dense array’ of ultra efficient multi-junction PV cells that convert solar energy into electricity. The heliostat exhibits unique (patented) optical and mechanical properties. The collectors track the sun and aim the rays into the converter. This configuration allows the same power to be produced with half the collector area and less than 0.1% of the PV cell area needed than traditional PV solar panel based power stations.

 

RayGen offers unique value to energy utility companies and system integrators. The collector area is 40% smaller, and the plant mass 65% smaller than current CPV. Compared to traditional PV plants, performance is 2.4x higher, installation and maintenance is cheaper, it’s highly reliable and, most importantly, capital expenditure is 95% less. RayGen’s technology is also the leader in PV performance, since it presently holds (with the University of New South Wales, Australia) the world record in solar system efficiency: 40.4%, as independently verified by NREL.
