Underwriters Laboratories Expands Its Global Photovoltaic Footprint to Japan

New PV laboratory in Japan offers full portfolio of services and enables manufacturers to speed up their time to market

NORTHBROOK, Illinois, September 9, 2010 - Underwriters Laboratories (UL), a global leader in safety testing and
certification, announced today the opening of a testing and certification
facility for photovoltaic (PV) equipment in Ise City, Mie Prefecture, Japan.
In addition to offering performance and safety testing services for PV
equipment in Japan, the facility will provide technical support to Japanese
PV equipment manufacturers as they develop their businesses and enter
overseas markets.

The global demand for sustainable energy generating sources, such as PV
systems, has increased. The governments of the U.S. and Japan, as well as
market-leading Germany, continue to take proactive steps to develop the PV
market and accelerate PV equipment production. In Japan the government's
roadmap for reaching greenhouse gas reduction targets includes a national
policy to expand the reach of PV power generation to 10 million households by
2020, which constitutes a 21-fold increase compared with 2005.

PV systems, which consist of PV modules and panels, junction boxes,
inverters and power converters, are permanently installed on roofs or
ground-supported frames and thus are prone to degradation due to wind, rain,
hail and age. Accordingly, improving the safety and verifying performance of
PV systems is critical for them to receive widespread adoption.

UL has been engaged in formulating PV equipment safety specifications and
standards since the 1980s, and has contributed to the safe operation of PV
equipment by providing safety testing and certification services for PV
equipment manufacturers worldwide. "We continue to expand our service
capabilities to meet the recent increase in global demand for PV product
evaluation services," said Jeff Smidt, Vice President and General Manager for
UL's Global Energy business. Just within the last couple of years, UL has
opened PV testing facilities similar to the new Ise City facility, in San
Jose, California, U.S.; Suzhou, China; and Zeppelinheim, Neu-Isenburg,
Germany. "With further plans to open a testing facility in India, UL is
implementing a concrete, large-scale investment plan in North America, Asia,
and Europe, which are the world's largest PV markets," Smidt added.

The new PV testing facility in Ise City has 14 cutting-edge testing
chambers on a 2,000 square-meter (approx. 21,000 square-feet) site. It is
fully equipped with solar simulators emitting artificial sunlight, impact
testers (which test the durability of a device against physical impact) and
hail testers. Moreover, to meet strict testing requirements, the facility is
staffed by engineers and technicians with expert knowledge of PV testing
work. To learn more about the new facility, visit:
