Delta's Featured Products at PV Expo 2009

High Concentrating Photovoltaic (HCPV) System Solution – Delta Electronics, Inc
http://www.delta.com.tw/product/cp/cpv/cpv_main.asp
Since 2005, Delta's strategic partnership with Spectrolab has developed high quality concentration photovoltaic receivers for their high efficiency multi-junction solar cells. Two standard cell assemblies (CA0505 and CA1010) are already available to the market and are used by many CPV module makers worldwide. Delta's first generation MA0505 high concentrating photovoltaic (HCPV) module uses Spectrolab's 37% high efficiency multi-junction solar cell and has constantly achieved over 25% efficiency in production. The HCPV module has passed the 13 testing criteria of IEC62108 and Delta has shipped over 4,000 units to customers.
Besides the HCPV module, Delta will also debut its own tracker and sensor products during PVEXPO to offer complete system solutions to customers. Meeting strict requirements for operating in harsh environments, Delta's tracker has sensors with anti-jamming functions for cloudy conditions and it is able to achieve a high precision tracking accuracy of 0.05 degrees. All Delta products are RoHS compliant.
