looking to mount Renogy’s flex solar panels to plexiglass on top of a alumines brand roof rack, verses directly to the roof rack floor, good or bad idea.. thought it might give the panels more support?!
Suppose that you have a 100 watt solar panel that is 15% efficient. That means that 85% of the sunlight falling on it is turned into heat and 15% is turned into electricity. For a 100 watt solar panel that is about 1000 watts of heat - so roughly 10 each 100 watt light bulbs.
The heat has to go "somewhere" and if you mount them on fiberglass (an insulator) it mostly just makes the panel hotter until it fails.
If they are mounted on a conductor (Aluminum or Steel), this helps a lot. If the backing is ~ 2x the size of the panel, this helps more. If there is some spacing for air to get under the conductive backing material this also helps.
We finished our build around May - It took us 3 months to get the van as we custom ordered it with the options we wanted. It arrived in Mid December, so we had to try and build it during the winter months. That was brutal! We have tried to maximize space and functionality in a...
Many of us got vans to take us to pretty places, where we could then take pictures of the van. I thought it might be fun to share some pictures of your van in the wild. I'm afraid my initial contribution will be of my former Transit, but hopefully I can add some Promaster pictures in the next...
This forum has helped me a ton when i decided to buy a new PM and build it out for whatever comes my way. It's turning 2 in July and as some may come to realize if you are doing it yourself it's almost always going to be "in progress".
Anyway, I haven't made any significant additions...
