Updated 11/10/2026 | Published 11/06/2026

Question:

I have a factory installed Go Power GP-PV-260M solar panel. The roof is pre- wired for a second panel. What panel do you have to go with this one? Thank You

Hey Curtis, welcome back! For your factory-installed Go Power GP-PV-260M 260-watt solar panel I recommend the Go Power Overlander Solar Panel Expansion Kit #GP76AR. This will take your 260 watt setup to a 460 watt setup. What all are you powering with solar on your camper?

I have the same panel from the factory and added three of the GP76AR panels. I would like to know what you mean prewired for a second panel or do you mean that the factory controller will handle a second panel? I can give you more insight if I can get this info from you.

@SteveO I'd assume what Curtis means is that the controller has a second port for an additional panel but hopefully he chimes in and clarifies that. Thank you for wanting to help though!
