I use "the google" for my data and some presumptions for my calcs. There are many, many factors that would need to be yet to hammered out. Just like in my area and I am sure in other parts of the world, once the price of oil surpasses electrical rates, more and more folks will convert to electrical heat. This would then increase the size of the solar array needed in the back yard. My numbers are just the starting point. I just thought another way to crunch the numbers. I post my findings when I am done.
