Our house proved to be challenging because of the large maples to the south of our house (which I am reluctant to cut down because of the great summer shade in our back yard). Tom and Watts up were the only company we obtained estimates from who suggested putting panels on our large shed, in addition to putting panels high on the roof of our house. This allowed for a larger system - although still small - and one that hopefully will overcome many of the shade challenges that we face. Their website is fantastic as well and allows people to learn more about the panels and do their own estimates. Thanks Mike and Tom for making this happen for us!
