Starting to outfit a small fibreglass trailer and went with the Renogy 300w Premium Kit. Already pulled the trigger, went for the lightweight ETFE Rigid panels. Have not been able to find any info, reviews on them. I am guessing they are the same ETFE flexible panels they sell only in a rigid frame. Makes sense to this noob, I get the lightweight benefit without the heat issues of the flexibles on the fibreglass roof. Curious if anyone has any experience with them. If they are crap, don’t let me know ;-), but odd ( maybe??) that I can’t find any info on them other than the Renogy website. Thanks.
