  • Solar at Canada’s Paterson Lake Telecom System Reduces Generator Use by 60%

    Application: Telecom
    Location: Paterson Lake, Northwest Territories, Canada
    Year: 2015
    Product: TriStar 600-Vdc charge controllers and ground-fault protectors
    System size: 15.6 kW
    Partners include: NorthwesTel, Howell-Mayhew Engineering, Action Electric, JA Solar

    An off-grid telecom system at Paterson Lake in Canada’s Northwest Territories traditionally relied on a diesel generator for electricity. Despite uneven slabs of rock, Howell Mayhew Engineering and Action Electric developed a 15-kW solar PV system to reduce generator use by 60%. Workers dropped off equipment from a helicopter because of no road access for 80 km. The installation uses black 260-W JA Solar modules and batteries for clean, reliable cost-effective solar electricity. The project also incorporated Morningstar 600-Vdc ground-fault protectors and charge controllers. Now, the system only requires the generator during the winter.

  • Telecommunications in Canada’s Northwest Territories

    Application: Telecom
    Location:
    Wolverine Creek, Northwest Territories, Canada
    Year: 2015
    Product: TriStar 600-Vdc charge controllers and ground-fault protectors
    System size: 15.6 kW of solar
    Partners include: NorthwesTel, Howell-Mayhew Engineering, Action Electric, Conergy

     Canada’s vast Northwest Territories encompass large areas of forests, lakes and tundra. Howell Mayhew Engineering developed a telecom PV system on the top of a mountain at Wolverine Creek near Great Bear Lake. The system included 60 Conergy 260-W multicrystalline-silicon modules and six Morningstar 600-Vdc ground-fault protectors and charge controllers.

  • 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
    Partners include: NorthwesTel, Howell-Mayhew Engineering, Action Electric

    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.

  • Remote Telecom Repeater Station in Canada

    Application: Telecom
    Location: Canada
    Year: 2014
    Product: TriStar MPPT 600V with disconnect box
    System size: 7.2 kW of solar, 15-kW generator, 3,000-Ah, 48-V battery (two sites)
    Partners: Sunwize, Howell-Mayhew Engineering, East Penn Manufacturing, OutBack Power

    Sunwize chose the Morningstar TriStar MPPT 600-V controller for a Verizon facility in Canada because the device could withstand arctic regions with temperatures of -67°F to +86°F (-55°C to +30°C). The controller’s long wire-runs, reliability and ease of installation to produce a low angle of incidence were also considerations for its selection. In addition to solar, the project included a generator that used four, 3.6-kW OutBack Power inverters on a custom control panel. This generator hybrid project saved 70% on fuel consumption for off-grid cell towers with a microwave uplink.
