MT. PROSPECT, IL – Atlas Material Testing Technology LLC announced that, for a second time, First Solar Inc. has completed the rigorous Atlas 25+® Comprehensive PV Durability Testing program and received test result certification from Atlas' partner SGS, an inspection, verification, testing and certification company.
Testing was conducted on First Solar's original Series 4 thin-film photovoltaic module, which utilizes the core technology used in all of the company's product offerings.
The Atlas 25+ protocol is a proprietary, multi-dimensional durability test program designed to subject photovoltaic modules to the environmental degradation stresses that can be expected over long-term service. It provides manufacturers with the data they need to demonstrate long-term durability and to support warranty and performance claims, while reducing the costs associated with aftermarket product failure.
The Atlas 25+ program exposes solar panels to a series of stresses, including UV-A/UV-B exposure, salt spray corrosion, condensing humidity, solar/thermal humidity cycle, solar/thermal humidity freeze cycle, Arizona and Florida solar tracking (including peak summer) and initial, final and multiple interval measurements. In order to receive SGS certification, modules are required to have less than 8% degradation over the testing period.
“As part of the Atlas 25+ independent testing program, solar panels are exposed to harsh weather conditions similar to those faced during their lifetime,” said Richard Slomko, Director of Atlas' Weathering Services Group. “This is a tremendous achievement for First Solar to complete our Atlas 25+program again with impressive results. We are extremely pleased that the world's leading thin-film PV manufacturer continues to utilize our unique PV durability testing program to confirm module suitability for long-term operation in the world's harshest climates.”
