Installed a new solar array this morning. old one consisted of 2, 150w panels which did work well however last end of season I had some weird readings on the SOC meter showing negative input which made no sense at all. Found out one of those panels went bad. Had no choice but to get new ones but this time around I decided to go with 3, 175w units. Have not plugged anything in yet as I am waiting for the Sikaflex 291 under the standoffs to dry so not until tomorrow morning before making the final connections and test the system.

The biggest drawback of flexible panels is they have no airspace underneath and therefor tend to get too hot. People glue them down which is not at all a good choice. After scratching my head for a solution, I simply stuck 5 strips of closed cell foam underneath each panel which allows water to flow under and provides some much needed airspace/ventilation.
