Tishi Hery 100W Flexible Solar Panel Kit 18V 12V ETFE Monocrystalline Lightweight Thin Solar Panel Charger with MC4 Connector for 12V Battery, RV, Boat, Car, Trailer, Cabin, Tent

Shorted out after first day. Warped plastic and burnt hole through panel. These panels cannot have any shading or it will overheat and cause panel to burn through and burn what ever is underneath. I beleive these panels dont have as many bypass diodes in them like a hard aluminum frame solar panel does they only have one diode. Tishi Hery sent me 2 new replacements so i give them 3 stars but now i am stuck with 3 other panels that i realy dont feel safe installing. I also see that you cant connect these panels in series due to overheating.I would expect better performance specially since these panels are made for boats and rvs that get lots of uneven shading from the sun. I also didnt get the added watts from connecting these in series as you can see in pictures posted. They did change their design to oanels haveing 2 diodes instead of 1 diode per panel. Contacted them about my loss of wattage and havent gotten response.
