Solar Panels in High Wind

Assume that solar panels are mounted on an arch. It seems that high winds could easily damage solar panels. So, a good installation with high winds in mind should be made. Are there any experiences where solar panels were damaged in high winds? Any comments on installation that remains secure in high winds?

Re: Solar Panels in High Wind

Mine is mounted on the stern rail and anchored in the center of the frame to the back stay. It has been exposed to 60 MPH winds several times with no damage whatsoever. I suspect a lot of this depends upon how the frame is constructed and how securely it is mounted.



All the best,

Gary

Re: Solar Panels in High Wind

Mine are on a rear arch with a center pivot. I have ties front and back to adjust the angle to follow the sun.

They too have survived 60 knot squalls in both horizontal and tilted mode.

Re: Solar Panels in High Wind

As an alternative to an arch, this has worked out very well for us. So far winds have probably not exceeded 65 knots, but unless they are hit by something, I don't see why they wouldn't survive hurricane force winds.

Re: Solar Panels in High Wind

I haven't heard of anyone losing them except from debris. I'm sure it is possible but unless the install is really shoddy, or you get hit by a bad arse hurricane, probably not worth worrying a lot about.

Re: Solar Panels in High Wind

Some close up pictures of a solar panel mount being fabricated. Will be very strong.

Re: Solar Panels in High Wind

Fwiw - When we had our RV, people on the forums attached panels to their roof with 3m VHB tape. I could not believe that would hold at 85 mph on the highway, but never heard of a failure.

Re: Solar Panels in High Wind

Any solar array mounted reasonably horizontal (as most are) present a very small cross section to wind.

We have ours on a radar arch, contained in a light SS angle-section frame and bolted to the top of the two arch sections. We had Hurricane Pam visit us not too long ago and while we never got hurricane level winds, we have at least 60 knots across our anchorage and no damage sustained. Solar panels in their own right are actually quite strong.

Any sensible mounting arrangement will probably be OK in winds that will scare the average sailor.

That stuff is so strong you literally need to 'cut' it by using a flexible wire and a sawing motion to get it off once bonded.

They are horozontal.
