Cost-Saving Telecommunications in Weasel Lake

Application: Telecom
Location: Weasel Lake, Yukon, Canada
Year: 2015
Product: TriStar 600-Vdc charge controllers and ground-fault protectors
System size: 10 kW of solar PV

A solar-powered telecom system on a mountaintop at Weasel Lake reduces reliance on diesel. The goal is to eliminate the use of generators for six summer months of the year. Using a generator only half of the year significantly reduces fuel and helicopter-transportation costs. High-voltage TriStar 600-Vdc charge controllers and ground-fault protectors allow wiring sub-arrays straight into the charge controllers without any combiner boxes, which lowers costs by reducing installation time on site.
