Large Market for HCPV

 

► High Concentration PV (HCPV) outperforms traditional PV by 20% to 30% in high direct normal irradiance (DNI)1regions, which include over 30% of global electricity consumption

 

► Projected Total Addressable Market for HCPV of 9 GW per year with uptake of over 1 GW by 2015
