How safe are roof mounted solar panels

Just wondering if anyone has ever had a solar panel fly off while driving in high winds? Doesn't look like the 2 screws for each of the 4 mounting brackets are secure enough to handle driving down the road at 75mph in Utah and have wind to boot.

  • At 75 MPH in a wind I would think the solar panel(s) would be the least of your problems! Perhaps that could be described as dangerous driving. I's just sayn!
  • When I removed my panels to swap to new MH I had to use an 18" crescent to twist off the brackets held down with silicone sealant. Used lag screws through and sealant under each bracket. I could not pry them off, they just started to bend. The tilt brackets I use now only have 3M UHB double stick tape holding them on, been there for over 7 years without any problems.
  • They hug the roof and hang on. :)

    If you are driving 75 MPH in high winds. Then you have a better chance of your awning coming unrolled and ripping off more then any solar panel.

    75 MPH is the limit of most RV tires and more then some of them.
  • Never heard of it on this board. I never drive 75, and especially in wind.
