After months of research and signing a contract on April 15th, the solar panels we purchased are now installed! It took two days but will pay off well in the long run.
We bought a 10.4 kw system which consists of 40 REC 260 kw panels - 15 on the front and 25 on the back. Our calculations show this should be enough to cover our entire electric bill.
It is harder to see the panels on the back side of the house. We placed as many as we could on the back side because the sun angle is better. We should get 92% efficiency out of the back panels and about 72% efficient from the front panels.
