CYPRESS, CA – August 14, 2017 – Mitsubishi Electric US, Inc. Photovoltaic Division announced the successful test result of its Diamond Pro™ MJE photovoltaic (PV) module at 120 pounds per square foot (psf), one of the highest ratings in the industry.  This test load is four times the required ANSI/UL 1703 load of 30 psf. 

The Diamond Pro™ was tested in both positive (snow) and negative (wind) directions based on the 2016 harmonized UL 1703 and IEC 61215 revised standard. Intertek administered the independent, third-party performance testing of product samples at its Lake Forest, California laboratory. 

“Together we developed a customized compliance plan for Mitsubishi Electric to meet all applicable requirements, including becoming one of the first to have product samples pass a mechanical test load of 120 psf in both positive and negative directions,” said Sunny Rai, vice president of Electrical at Intertek.  “They were also one of the first PV module manufacturers to test and receive an ANSI/UL 1703 Type 2 class rating.” Intertek has been committed to supporting clients like Mitsubishi Electric in total quality assurance for over 130 years.

“Safety and reliability have been at the forefront of Mitsubishi Electric photovoltaic products since our entry into the solar industry in 1974,” said Gina Heng, vice president and general manager of Mitsubishi Electric US, Inc., Photovoltaic Division.  “In accordance with our corporate sustainability goals, Mitsubishi Electric uses lead free solder, a safer option for the environment.”  The company’s PV modules are built with a four-layer junction box with electrical connections completely encapsulated by the highest flame retardant used in the industry, UL94 V-0.  Mitsubishi Electric proactively tested and passed ANSI/UL 1703 new fire classification requirements nearly a year before the 2016 testing deadline imposed by the California Building Code (CBC) and the California Residential Code (CRC).
