Attach the solar panel magnetically to the roof

Today we would like to show you how our customer attaches a solar panel magnetically to the roof of his vehicle.
His goal was to attach a solar module to a car roof without the roof being drilled or glued.

Solution: Magnetically attach the solar panel to the roof

What to watch out for:

  • The Neodymium pot magnet Ø 42.0 x 9.0 mm with cylinder bore holds 32 kg and must be attached to the solar panel in a flexible manner so that it can adapt to unevenness or curves on the car roof.
    It only holds optimally when it is full.
  • First, the bottom of the magnet should be covered with thin insulating tape so that the paint is not scratched.
  • It should be noted that the magnetic force on a thin car sheet is significantly lower than as described in the magnetic data sheet.
    If the holding force is not sufficient, there are 2 options:
    – First option: glue a sheet of steel to the underside of the sheet metal roof
    – Second option: use more magnets
    I decided to use more magnets, it is more expensive but easier to implement.

  • During assembly: place a thick cloth under the magnets until the solar panel is correctly aligned.
  • When dismantling: place a flat wooden board on the roof and pull off the solar panel with a lever.

The solar panel was magnetically attached to the roof in no time at all. This type of mounting is suitable for solar panels on vans, mobile homes and trucks.
