In November of 2010 our 3.4 KW Photovoltaic solar system installation was completed by SolarCity. The question since we started this project was how much of a home's power can you generate with solar power here at 45 degrees North latitude? I've heard people claim 50%.
We are well over 8 months into 2011 and through the month of August our PV solar installation has supplied 48% of our electricity. The chart above, which is a chart supplied by SolarCity automatically shows how much was generated by the solar panels each month and what percentage of our average monthly usage that is.
