Never. If the wind in your area is blowing that hard, it's going to make noise no matter what. Your panels must be installed with framing a certain amount above your roof, that's true. I'm really not sure of the minimum amount. However, you are right: Panels like to be cool and work best raised above the roof line. Having them flush against your roof is a no-no, even if it looks "better" more flat. That being said, it's a typically minimal amount above your roof. Good luck with the install and thanks for going Solar! You rock. Steve, I’ve never heard of anyone complaining about wind noise from solar. Never.

I am about to install (or possibly have installed) a 10kW system on my roof that is almost 60' long. Do you have any suggestions how to ensure the installation is quiet and that I do not have expansion or wind noises from the aluminum framing? Also, is there a minimum distance off of the roof that the solar panel needs to be mounted for heat dissipation? I am trying to learn everything well in advance and appreciate any advice. Lastly, I cannot fit enough Sharp panels so I am looking at Sunpower and Sanyo which have smaller footprints. Any suggestions or alternate companies? Thank you, Steve I appreciate the info that I read on here.

I have done lots of reaserch and i would like to use the pro solar fast jacks for mounting to our s-curve concrete tile roof . I under stand about removing the tile and mounting the fastjacks to the rafters and then sealing , but what is the best way to do the flashing,, do you drill a 1" hole in the concrete tile and then use metal flashing,, thanks for your help Randy Hi David:

At the beginning you mentioned that leaking is one of top three concerns of your customers. Can you please let us know what two other concerns are? Thanks Hi David:

It is a two story modern contemporary house. We have an unobstructed southern sunshine that can generate a lot of solar energy. I'm afraid that if you anchor the panels to the EDPM there will be leakage. What is your solutions if there is one for this type of structure?

Like I said, perfect tilt matters almost nothing. in SE just shoot for 15 degrees or around there. FYI I find that when people use special racking systems that allow for a summer/winter adjustment... they end up saying 'screw it' and never adjust the thing, leaving it optimized for summer or winter year round. for perfect tilt, do a google search for magnetic declination.

You'd be surprised how little difference optimal tilt matters as long as you're withing 10 degrees. More important than tilt is orientation, and WAY WAY more important than orientation is shading. the racking system we used to use only went to 12 degrees if you stuck two panels in portrait.
