I saw a controller that activates an irrigation style solenoid valve to close it and divert flow to the panels. Is there any advantage / disadvantage to this type of valve as opposed to the typical 3 way automatic valves?
Solar Heater Controller using solenoid valve??

I'm not sure, but I've thought if using one of these myself. Only thing holding me back is the innability to find a 1.5" or 2" valve locally. Have you found one?

Yes, I can get them locally at an irrigation store. Actually, it was several years ago that I saw them, but I don't know why they would not have them now. I've got 5 of them on irrigation system - all 1.5"
Funny, yesterday I was thinking the same thing you wrote about in your other post. Getting a cheap digital thermostat, unsoldering the thermistor and embedding it in the rubber solar mat, then using that to control a solenoid valve. I'll be using the solar all winter, but just don't want the water going through the panels when it is cloudy and cold.
