JA Solar Holdings Co., Ltd., the manufacturer of high-performance solar cells and solar power products, announced a partnership and supply agreement with tenKsolar, Inc., a Minnesota-based solar technology company. Under the agreement, JA Solar will supply its high-efficiency "SECIUM" solar cell technology for use in tenKsolar's RAIS(R) rooftop array.

When deployed in the tenKsolar RAIS(R) array using static reflection as a proprietary cell-optimizing architecture, JA Solar's 19 percent efficient SECIUM solar cell yields an effective area efficiency (peak energy produced per unit of module area) of over 25 percent, resulting in superior rooftop energy density at a competitive installed cost.

"We are pleased to work with tenKsolar, an innovative solar technology company based in the United States," said Yong Liu, CTO of JA Solar. "By utilizing JA Solar's leading-edge, high-efficiency SECIUM Solar cells, tenKsolar is able to achieve a PV system with higher energy density output for commercial flat rooftop and space-constrained ground-mount projects, thus reducing the cost of delivered energy," he said.
