In my recent pool build our sales person sold us on the Terra Cotta colored solar panels so that they would match our roof tiles better. I agreed but now that I see them on the roof I wish I had just gone black. Our roof tiles are more brown then reddish-brown and the 'terra cotta' solar panels are more orange than anything so in the end I'm left with something that sticks out like a sore thumb but I'm taking an efficiency hit v.s. the black panels. I can't even really see the panels on my 2nd story roof from my yard anyway.
My question is, how big of a difference am I going to see w/ the Terra Cotta panels v.s. black ones? Is it a big difference or is it negligible?
