Hi. I have a panel on a vehicle installed by a previous (and likely very stupid) owner. I would like to purchase another panel and hook it up in series with this one (using an MMPT controller). Unfortunately, the panel does not have a label (it probably came off). I was hoping someone could advise me how to match a panel to hook up in series if at all possible.
The panel also looks different than any other panel I've used. There are NO solder lines on the surface of the cells or visible anywhere. The cells are dark blue (almost purple) with a bit of texture to them like rubberized handles. The array is 12 x 6 cells and it's currently producing 38v under load with sunny, indirect light, charging the battery bank at 144W (13.4V, 8.5A). If anyone has seen a panel like this, or knows how to hook panels in series, please let me know. Thanks. -Ball
