40 Solar Photo Voltaic panels, over 8 thousand watts, 8Kw of panels mounted for maximum winter power production. The winter angle, 42 degrees, also aids with snow shedding, half hour of sun will clear the panels.
40 – 200 watt Sanyo/Panasonic panels mounted like shingles to create a water shedding roof over the wood frame structure and cover the electrical system and batteries. The next step is to upgrade the battery system to provide up to 35 – 48Kwh of batteries to supply 5 days of power to the farm grid. Then Inverters to turn the 48vdc from the battery bank into 240/120 split phase power needed to run the water pump and other 240/120 loads. Presently the panels are directly connected to a 36vdc bussed battery and grid-tie system that pumps 2Kw back into the local grid. While better then nothing this is very a inefficient coupling that wastes over half of the power harvested and will produce nothing if the grid is down.
only 30 minuets of sunlight cleared the snow from the rack.
