I've got this same question on my 2015 21 which has a 150 Samlex solar panel and controller. I've got the trailer parked under a carport where it receives no sun. Pondering the addition of an extension panel that I could use at home connected in parallel with the existing panel to maintain the batteries and also use on the road when not parked in the sun for additional power. From what I'm reading the controller can handle up to 500 watts.
It seems fairly easy to hook them up in parallel with splicing connectors but the existing connectors are up on the roof next to the mounted panel.
Is there better options? I don't see the benefit of purchasing a panel with a separate controller and not have the system integrated.
