Adding a second solar panel on a Delta 292RL trailer

[sunnysidewoods]

Hello Alliance World. We have a 2026 Delta 292 RL trailer. To my surprise, the 400 Watt solar panel is a GoPower GP-PV-400M. That model isn't even listed on the GoPower website. I also did not find an equivalent 400 Watt single-panel system from Renogy. Has anyone successfully added a single panel to the existing panel? I see that BougeRV makes a single 400 Watt panel.

Most of the posts I've read in these forums are people adding multiple 200 Watt panels, and I suppose I could just replace my single 400 Watt with four 200 Watt panels, but it seems a bit of a waste. Any suggestions from the owners?

Thanks in advance, Andy

That panel, based on what I found, not available through traditional retail channels. It's made for the RV industry (looks like RecPro) and could be available through Alliance. That said, though it's easiest to add the same PV panel to an array, it is not a requirement. We live here in Florida, and like a lot of our neighbors, have solar arrays (I have Panasonic and also I'm lucky enough to have a battery backup). LG made some of the best solar panels in the world, are installed on many of my neighbors roofs, and LG stopped making them, all PV panels, in 2022. It is relatively rare for a solar panel to fail, but even when one panel in an array does fail you can replace it with another manufacturer's panel. YOu can see it in practice on home after home here. There are four metrics printed on your panel or panel label. Find a panel that matches those, or very close, and you are golden. If you are going to wire in series or parallel matters (current and voltage for example). The limits of the PV controller needs to be considered too.
