Performance of a micro-cell based transfer printed HCPV system in the South Eastern US

Printed micro-cells are the basis of a more cost effective and highly efficient HCPV module design. Module efficiencies of 33.9% at STC have been demonstrated for modules designed for commercial use. An array of these modules were deployed in a 3.5 kW system in Huntsville, AL to validate the design, demonstrate the reliability of the system and collect on-sun data to understand system performance. The first six months of performance data is presented along with results from soiling experiments.
