A typical solar mounting system of roof top installation will allow for a sufficient air gap between the roof surface and the panel allowing airflow to have a cooling effect on the panel.
Air gap for flexible solar panels.
Our lightweight solar panels come with an install kits option for providing a vented.
Solar cable glands bridge the gap between the roof and the interior of your van.
When panels run less hot their longevity is also improved.
The transfer rate of the flexible solar panels is also about 23 that is high when compared to traditional panels.
A vented air gap allows heat to escape and helps the panel and the surface they are installed on maintain a lower temperature.
The watt price of the flexible solar panels is higher than the rigid panels.
If you do not have a special reason for using flexible panels they are just too expensive compared to normal ebay panels of the same wattage perhaps 3x to.
The performance output power of solar panels reduces when they get hot.
We have hail during the monsoon season annually in prescott valley az about 1 4 to 3 8 inch in size.
They are small.
In india there is a team did a detailed thermal analysis on a typical roof top solar panel installation to arrive at optimum air gap and the same is.
It is a good idea to design a gap between the panel and the roof for air movement.
I have no experience with flexible panels as they are too expensive for my liking and you can mount ordinary panels easily with an air gap to achieve the objective to help keep them cooler.
Advantages when compared to flexible solar panels.
I bought a semi flexible solar panel to test it flat mounted and hail pitted it at least 2 or more layers down in the protective layers and shorted out the panel in less than 6 months of use after 2 hail storms.
Now what you need to keep in mind is that the flexible solar panels make use of monocrystalline wafers.
Mounting or gluing panels directly to the roof loses important cooling airflow from the underside.
