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...

Here's the plan:
He has a Blue Sky Solar Boost 3000 rated at 22 amps w/24 volt panels. He's going to wire the panels so at least one of them is switched prior to the controller. In the somewhat rare occurrence of mid day sun when one of the panels exceed 11 amps @12 volts he can switch one panel off for controller protection. It is my opinion the great majority of the time both panels can be operational-due to sun angle or temperature.
FWIW it appears the controller will self limit to the 22 amps. But it is not recommended to use this as a feature-just as a protection. This is both in the documentation and a conversation I had with Blue Sky tech support.
Essentially this is a case of taking advantage of the low price of panels to use in sub optimum conditions-which are more common than not.
This is a weekender with a family who's coming home with too low batteries and not a good way to recharge in storage lot. He has plenty of battery capacity but needs solar to make up deficit once stored, and to keep a bit more ahead of the curve when camped a few days.
