This 4.2 kW system was installed fall of 2016. It consists of 16 – Canadian Solar 265 watt modules on a 60 degree angle roof rack. The 60 degree angle promotes snow shedding and maximizes power production through the dark winter months. The inverter system is a Magnum PAE 4448 pure sine wave inverter, which delivers 240 volt AC to supply all house loads. An 8 kW propane generator supplies backup energy during the winter when there is insufficient solar input.
