First Solar, Inc. Successfully Completes The Atlas 25+ Testing Program

The Atlas 25+ protocol is a proprietary multi-dimensional durability test program designed to subject photovoltaic modules to the environmental degradation stresses, which can be expected over long-term service.

Mt. Prospect, IL – Atlas Material Testing Technology, LLC, the global leader in weathering technology and services, is pleased to announce that First Solar, Inc. has completed the rigorous Atlas 25+ Comprehensive PV Durability Testing program and received test result certification from Atlas' partner SGS, the world's leading inspection, verification, testing and certification company.


The Atlas 25+ protocol is a proprietary multi-dimensional durability test program designed to subject photovoltaic modules to the environmental degradation stresses, which 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. "First Solar was able to achieve outstanding results with the Atlas 25+ program. We are extremely pleased that the world's leading thin-film PV manufacturer chose to utilize our unique PV durability testing program to confirm module suitability for long-term operation in the world's harshest climates."

"The value of our program to the industry can be measured by the growing list of leading module manufacturers that have sought our testing services," Slomko noted. "First Solar joins a prestigious group of PV industry leaders such as SunPower, LG and Suntech, which have passed the Atlas 25+ testing protocol and use the Atlas 25+ mark to promote the efficiency and durability of their PV modules."

WS510 Secondary Standard

WS510 Secondary Standard

In the monitoring of large photovoltaic (Utility Scale), in assessing potential sites (Solar-assessment), or in up and coming electricity cost saving initiatives projects (Commercial & Industrial), the WS510 now provides the market a secondary standard pyranometer, ultrasonic wind speed, ultrasonic wind direction, temperature, pressure and humidity all in a single unit.. This sensor meets the high demands of the world meteorological organization (WMO) through the active valving at air temperature measurement and the inertia- and maintenance-free measurement of wind speed and wind direction on the ultrasonic principle. Equipped with a Kipp & Zonen pyranometer of the secondary standards, the WS510-UMB Compact weather sensor from Lufft unites the precision of a variety of meteorological individual sensors in a single all-in-one device, for the first time.
