I am ready to add a solar panel to my 20 TT. The trailer came with a 100W Renogy panel. I am thinking I would like to add a 100W or 200W panel. We don't have any special electrical needs when dry camping other than lights, charging devices, etc.
This new panel will probably be hooked up on the ground. Just wondering if there are any issues I should be aware of regarding connecting the new panel to the existing system and what size panel I will most likely need. Thanks.
Match the existing panel. Connect in parallel. Done!
If 200 watts is not enough, and the controller can deal with the extra amps, then add a third identical panel.
