Solos Solar Array production stats – October

The month of October we produced over 1.73 MWh (Megawatt hours) of power on the farm.

In the last month I have added a second sol-ark inverter, this changes how the panels are balanced. Since I only have one channel of solar power coming in I really need to consider adding more panels on additional channels now I have two inverters. With only 5500 watts coming in on each, one channel is simply not enough for two inverters. So I will soon look into increasing my panel count. But for now I am making a steady 1.7 megawatt hours last month.

That white stuff is not snow, but powdered lime. We are using it to attempt to keep the weeds down. We will know next year if it works or not.
