If you've got enough roof space, you might wish to look at the size of the panels in relation to their output capacity to avoid having insufficient panels that you need more of later.
I decided to get Solar Panels in July of 2011, and now with almost 7 years of data, I thought I’d share my finding, and what you can expect if you decide to go with …
