Carmanah Technologies Corp., a Victoria, B.C.-based manufacturer of solar power products, has provided seven remote solar power systems to Duke Energy Gas Transmission, a company that stores and distributes natural gas throughout North America.
Carmanah's solar power systems were installed for the Grizzly Valley Block Valve Warning System in Chetwynd, B.C., which is located in the foothills of the Canadian Rockies. Each system includes a BP Solar 125 W solar module, a Carmanah phase change battery enclosure, a tower mount and a Carmanah PV-3 controller. These solar power systems are unique in their use of the phase change battery enclosure, which helps to maintain battery capacity and extend the life of battery system, the company says.
