KYOCERA Receives UL's Class 1, Division 2 Certification for KC-Series Solar Photovoltaic Modules

Modules are approved to power applications in hazardous environments

SCOTTSDALE, AZ (December 4, 2003) - Kyocera announced today that it has received an advanced Underwriters Laboratory (UL) certification for a broad range of its solar photovoltaic modules. The UL Class 1, Division 2, Groups A, B, C, D certification has made Kyocera's KC-Series modules ranging from 35 to 120 watts "UL approved" for use in hazardous environments containing volatile flammable liquids, gases or vapors.

Kyocera's KC-Series photovoltaic modules have proven to be highly efficient and adaptable for industrial PV power applications. The Class 1, Division 2 certification will allow these modules to be installed in hazardous environments common to the oil and gas, mining and chemical industries, as well as many other industries which seek solar energy solutions with a higher safety rating.

Constructed with 6-inch multi-crystalline PV cells, Kyocera PV modules offer a conversion efficiency exceeding 14 percent. The cells are encapsulated between a tempered glass cover and an EVA pottant and an aluminum foil backing sheet for maximum protection even in the most severe environmental conditions. The entire laminate is installed in an anodized aluminum frame to provide structural strength and facilitate installation. A sealed junction box attached to the aluminum frame houses the wire termination contacts. All Kyocera PV modules carry a 25-year output warranty.

An industrial solar electric system with Kyocera PV modules will help avoid the need for high-cost utility extensions, while providing a more cost-effective alternative to propane-powered thermal electric generators (TEGs). Kyocera PV modules are designed to provide reliable power for a wide range of demanding applications, including pipeline control, flow and tank monitoring, chemical dispensing, compressor control, machine control, and wireless data solutions. The new UL approval enables Kyocera to engineer and integrate many more customized Class 1, Division 2 solar electric systems for industrial use.
