Collaboration will extend both companies’ global-testing capacity.

Underwriters Laboratories (UL), Northbrook, IL, a has entered into a strategic alliance with Atlas Material Testing Technology, a leader in accelerated weathering instruments and weathering testing services. This alliance enhances both companies’ global-testing capacity and expertise in accelerated-aging performance and enables them to provide faster testing and certification turnaround-time for manufacturers specializing in solar-energy products.
Collaboration between the two companies has already shortened cycle times for customers seeking the UL listing for solar modules and power-system accessory equipment. Not only are outdoor and aging tests for long-term durability a critical component for meeting safety and performance standards, but they also provide manufacturers with the data they need to demonstrate long-term durability to support warranty and performance claims. These tests reduce the costs associated with aftermarket product failures.
Jeff Smidt, VP and general manager of UL’s global energy business, said, "One of the great benefits that are available through this alliance is the geographical diversity of existing and new testing sites that allows us to minimize project delays that otherwise might occur due to natural weather conditions." Smidt added.
Atlas’ 21 outdoor weathering sites globally include the Atlas Solar Test Center and exposure facility in Arizona, a benchmark for outdoor-exposure testing possessing high levels of solar radiation and elevated temperatures.
Rick Weiler, CEO of Atlas Material Testing Technology, said, “Our combined resources generate the synergies to provide much needed laboratory and outdoor testing capacity for solar panels and equipment.”
Recently, UL has invested in additional capacity for the testing and certification of solar-energy equipment through the expansion of its existing and new facilities and partnerships. UL currently operates Photovoltaic Centers of Excellence in San Jose, CA and Suzhou, China, and will open new testing facilities this year in Germany and Japan.
