24 volt solar panel recommendations?
Is this panel decent? Or is there reason to buy one of the slightly more expensive panels from Solar Blvd? Friend has Blue Sky controller capable of using the 24 volt panels. https://www.solarbl...

He already has the controller-and he will upgrade it if he's switching off a panel too often and giving up needed power.
Switching one panel on and off is not practical. It requires climbing the roof to connect-disconnect MC4 plugs, or running an extra wire loop all the way to the inside of trailer with a switch on it. Either scenario is complicated, and you might not even be there at that exact moment when switching is necessary.
He will not know how much of "needed power" he will be giving up. It doesn't sound like he has proper means of monitoring this. One thing is certain - with 20A unit he WILL be giving up some power in Ca in winter, and yet more power in summer.
But, like Salvo implied, if it goes up in smoke, this won't be a big loss. Because then he will do what should've been done from the beginning - get a 40-45A controller.
