Enabling Technology of Ultra High Concentrating Photovoltaics (UHCPV) for generating green energy.

 

Powered by the innovative thermal management and packaging technology from NeoPac Universal Platform, NeoPac Solar Engine is enabling the Ultra-High-Contrating-Photovoltaics technology. Compared to HCPV systems which concentrate sunlight to intensities of 200 suns, NeoPac Solar Engine is much more advantageous because the cooling system can effectively remove the heat generated by over 800 times concentrated sunlight

Cooling is a critical factor for HCPV

Without focusing and adequate cooling, the concentrated sun light is so powerful that it can burn through a package. NeoPac Solar Engine can effectively remove the heat generated by the concentrated sun light. NeoPac provides patented technologies for CPV cooling. The excellent cooling allows solar cells to take double concentrations of sun power, and thus more than double power throughput.

NeoPac's Solution doubles power throughput with NeoPac Solar Engine by gathering more sunlight. The modular design of unified NeoPac Solar Engine leads to cheaper installation and maintenance.

Lower materials cost (solar cells and trackers) by more then doubling power throughput per solar cell area
  • Does not need heavy and expensive aluminum receiver plate (~3kg/m2)
  • Requires smaller solar cell area at 800 suns
  • Needs less trackers and converters with 800 suns
Lower packaging cost by offering a unified solar engine with readily available components, and materials

Current Packaging Technology is expensive because each CPV vendor has its own customized packaging process. Packaging is done in two stages, one after cell manufacturing and the other one during panel assembly. Solder and conductive adhesive have high thermal resistance and are prone to long term reliability problems.

  • Heat sink is already an integrated part of NeoPac Solar Engine
  • Cheaper and more efficient with a unified packaging design
Lower system design cost by offering the unified solar engine for all customers
  • NeoPac’s design is lighter
  • NeoPac’s design is plug-and-play
  • Less land space usage
Lower installation, operation and maintenance cost by offering the plug-and-play design
  • NeoPac’s design allows replacement of a single solar cell
  • NeoPac’s parts are easy to replace

Overall Advantages of NeoPac UHCPV

  • Shorter construction period (about 1 year)
  • Suitable for large, medium and small scale power stations
  • Highest energy conversion efficiency
  • Near term efficiency improvement (35% now, 45% in 5 years)
  • Smaller land usage
  • Does not require system water
