Just a couple of observations about the installations shown. Firstly I would suggest find a method of blanking the leading edge of your solar panels to stop both wind and debris. Wind may cause vibrations which will annoy at the least but you wouldn’t want both electrolysis or undue wear. Leave the rear open for ventilation, pressure equalisation and drying. Compriband tape is a good option.
Equally any debris that compacts underneath the panels will cause mould and who knows what.
I’ve noticed a trend of using coiled cable to connect the wiring between solar panels and controllers. I understand the need but have to disagree with the method. Once again that coiled wire is bound to vibrate against your vehicle finish and cause wear if not noise. I’m looking at other methods for my installation and if I find one I’ll post it.
Finally, I may be wrong but solar panel manufacturers I’ve dealt with don’t recommend putting the panel directly onto a surface. They suggest putting a barrier in between to assist with heat dissipation. Apparently heat reduces the efficiency. I’ve used 6-8mm polycarbonate twin wall, ensuring the channel is in the same direction as airflow. Fit their ventilation plug at the front and jobs done. If you just suspend the panels, chances are they won’t last long. Speed and airflow will cause micro oscillations that will break down the panels structure. Always support the panel across its entire area.
Thanks for sharing.
