ACOPOWER 200W Solar Panel - High Efficiency Monocrystalline 12V Solar Panel for RV, Boat, Marine & Off-Grid Systems | Portable Power Solution for Camping, Cabins & Emergency Backup

Seems to be of good quality. Charged up my deep cycle battery quickly using a decent MPTT controller designed for 12vDC systems and my battery type. Panel is a good size for my vintage van conversion and I like that the panel has pre-drilled mounting holes on both sides of the frame for easy, secure mounting. You can remove the back plate to reveal the soldered connection inside. If careful, you can replace the leads. The positive is on the right and negative is on the left when looking at the junction box on the back of the panel. Double check with a vote meter before connecting to your charge controller. Replacing the two diodes is possible on this panel if that's ever needed.
