I have unique situation where I may be able to heat the BACKSIDE of the solar panels that are on a trailer roof.
This would be with warm air on the back of the panels. My worry is that the FRONT of the panels might stay somewhat cold.
I guess I'd have to experiment to see what the heat transfer rate is in different situations.
Eg - conditions like snow might lead to more cold and more rapid rise in VOC than rain, etc.
REC 350W 144 Half Cell Solar Panel with appx 46.7 VOC (open circuit voltage).
Idea is to make sure these don't exceed the 150 V max of the Bluetti EP500Pro internal controller.
OR perhaps there are some devices for me to consider to regulate voltage flow ?
Eg - perhaps some kind of device could automatically detect a rise in VOC and shut down or lower the VOC?
Otherwise, and on all warm days of the year, it would be great to get the full voltage out of the panels.
The question, would it make sense to put hot air (eg - up to 85 F) onto the back of solar panels when the front is exposed to cold ?
The coldest temperature on record in the area is -10F. Generally it's only about 28 F at worst (but this is still below freezing).
My only other thought is that if big pieces of hail hit the panels, and one side was ~70 and the other was ~40, the panels, it might break the panels.
But that's not likely (or easy to deal with in any event, even if the panels are not heated).
Thoughts ? Considerations?
