Multiple Cooper divisions, including Cooper B-Line, Cooper Bussmann, Cooper Crouse-Hinds and Cooper Power Systems, will showcase Cooper’s breadth of solar products at Intersolar Booth #7558. As Cooper’s latest solar offering, Cooper B-Line will introduce the ARISTATM commercial rooftop mounting system at the event. This cost-effective and easy to install solar PV mounting system features standard electrical components and no loose hardware. The ARISTATM system’s pre-assembled frames effectively angle solar PV panels in the optimal position for maximum performance. With a high degree of flexibility, the ARISTATM system can be used for landscape or portrait mounting of PV panels for both ballasted and positively tied solutions. In addition to ARISTATM, Cooper B-Line offers a comprehensive set of custom engineered solutions for mounting solar PV panels in ground, commercial roof and openstructure applications. Also, a designated Cooper B-Line Solar Team is available to help customers to meet their cost per watt requirements for various solar energy applications. -More- Cooper Industries – Page 2 Adding to Cooper’s range of solar options, Cooper Bussmann and Cooper Crouse-Hinds offer combiner box solutions that provide the housing to combine and connect the conductors from several arrays or solar panels into one main bus or feed.
