Record Set for Flexible Solar Panel Efficiency

SoloPower’s next generation solar panel has achieved an aperture area efficiency of 13.4 percent, a record for flexible copper, indium, gallium and (di)selenide (“CIGS”) based modules. The measurements were made by the National Renewable Energy Laboratory (NREL).

“Importantly, the cells were made in SoloPower’s San Jose manufacturing facility, so we know we have the systems in place to deliver high-efficiency, light-weight, flexible modules to our customers around the globe,” said Tim Harris, CEO of SoloPower, a San Jose, California-based manufacturer of flexible thin film solar cells and modules. “This benchmark is a testament to our technology team and to our commitment to continuously pushing the envelope in power and performance, while reducing costs for our customers.”

SoloPower uses innovative manufacturing technology to produce low-cost, high-efficiency CIGS-based photovoltaic cells. The CIGS cells are then packaged into unique, flexible, lightweight solar modules. The modules require less balance-of-system hardware and are easier to install than traditional solar panels.

“SoloPower’s achievement of an aperture efficiency of 13.4 percent for our flexible CIGS modules is a result of efficiency improvement projects that have been in place during the past two years,” said Dr. Mustafa Pinarbasi, CTO at SoloPower. “We were the first company to certify flexible CIGS modules to UL 1703 and IEC standards (61646 and 61730) in 2010. We have improved the efficiency from 11.2 percent to 13.4 percent with new processes implemented in our roll to roll production line and have a strong pipeline of improvements yet to come this year.”

Currently SoloPower is hiring engineers and technicians for its state-of-the-art, high-volume manufacturing facility in Portland, Oregon, which will begin commercial production later this year. SoloPower’s operations in Portland are ultimately expected to have a capacity of 400MW and employ 450 people.
