My only problem is how do I install them?
What are the challenges with these panels?
Would love to hear your thoughts/experience with them.

My frame is similar to the one above but standing up instead of sideways. I had my sister seal the frames with deck stain/sealer and they look sharp. I currently have 6 of them working because the midnite classic 200 can't handle all ten so I have to order another charge controller. I am using 14 12v 115 ah batteries wired as 24v. And we are producing 8-10 kW per day in Sierra Blanca, TX. The key to using these panels is airflow. My frames are 2x4 notched and assembled like a picture frame. Only 3/4 inch of the panel edges are on the boards and the backs are left exposed. With temps hitting 109 we have had no issues with heat build up. I used clear silicone to glue them to the frames and started to use pieces from the notching to secure them but the fit was so tight, I started removing the slats. We where surprised at the size (78x39) but with 105 acres re have lots of room lol.
