PAXCESS 60W Portable Solar Panel

Useful form factor and good cells but poor controller setup. Folding panels are great in theory, compact carry and protects panels when not in use. Mono-crystalline cells are definitely better than poly-crystalline cells on the Togospower 60W panels. However, like the Togospower panels, the controllers are questionable and should have been included as option not hardwired. Returned and purchased standard flex panels without controllers. Folding panels are great in theory, compact carry and protects panels when not in use. The big draw about the folding panels is the portability. This panel checks those boxes unlike the standard glass or flex panels. That is really good. The mono-crystalline cells are definitely better than poly-crystalline cells on the Togospower 60W panels. I returned previous panel because it was not reaching anywhere close to full power output in southern California sun. This one can reach it but it is very erratic when it does. The controllers are questionable and should have been setup as an option and not hardwired. Power stations, like the FlashFish I have, already have integrated charge controller. I would prefer to bypass the controller on this panel and connect straight to the station. Main problem I see is the inconsistent power output. I saw wild power output fluctuations when I measured with a clamp meter. Sometimes it would be steady at 2.9amps in absolute ideal conditions, no clouds & afternoon sun. Other times, it would cycle between 0 to 2.9amps like it cannot mke up its mind. At the end of the day, whatever the reason, it would charge the power station 40Wh at best on at least 3 hours of usable sun. Something is definitely wrong with it. To test the theory that it may be the controller, I purchased a 50W Sunpower panel that does not have controller. I connected the panel directly to the station and, as expected, no more wild fluctuations. I suspect the controller is either poor quality or does not get along well with integrated controller in the station. Having the option of bypassing the controller would be ideal. Include MC4 cables for cross-platform compatibility. I mean, I wish the Sunpower came in this form factor, but it simply does not nor do I believe they will make anything like that. In summary: 1. Great form factor. 2. Solid mono-crystalline cells. 3. Did not work as rated. 4. Suspect Questionable controller and setup.
