Mixing different brands of panels isn’t necessarily a dealbreaker, but there are a few things to watch out for. The big thing is matching voltage and current—if the specs don’t line up pretty close, you’re likely to end up losing efficiency, and it can be hard on your charge controller too. I’ve seen folks put a Renogy panel in with a BougeRV and it worked okay, but only after checking the open-circuit voltage and wattage ratings first. Sometimes, if one is less efficient, it’ll end up dragging the whole system down to its level.
Honestly, I stick to one brand per array just to keep things simple, especially when troubleshooting later. It’s just easier on the nerves, and replacement parts are less of a puzzle. Sometimes you snag a deal on a different brand though, and I get the temptation!
Curious if anyone’s noticed newer panels holding up better, especially with hail? Haven’t had any break yet myself
