Installed a single solar panel to keep a single 12 V battery charged on our Jay Feather X23B. We purchased a Renogy 100D on Amazon for under $200 which was really worth it. During our initial testing, the panel produced 20 V of power running at 5 amps keeping the battery constantly charged while running multiple lights and fans. It definitely helps that we recently swapped out all our light bulbs for LEDs. As you can see from the last photo, we also put a 15 amp fuse on the wiring coming from the panel.
