Unirac or Prosolar???

marks Registered Users Posts: 17
As I move forward with submitting my plans, I've yet to decide which racking system to use. Since the roof is concrete tile with a 10:12 pitch, I plan on using stand-offs allowing about 2" between the tile and the bottom of the pv frame. The Prosolar Fast Jack seems like a very clean approach, however their web site doesn't off the engineering specifications that Unirac does. Independent of these observations, do you guys have any thoughts on either of these products? Thx

    I'd look for more than 2" if you are in a warm summer area. Keep those panels cool !

    I am sure Cristina @ prosolar can get you any engineering specs. If you have a cement tile roof you will probably have to use the tile track. Both products work well but I have used the prosolar products alot more. Oh, and Mike is right about getting them up off the roof as high as possible.
