I'm from Illinois. Camping out in the AZ desert at the moment, I can see that solar is easy out here. Do the math, install it right, and you are golden. Camping in the eastern 2/3rds of the US, i...

I have an Eco-Worthy 20a MPPT controller ($102) that some other members here also have. It works very well on one 24v panel up to about 250w or a bit more, and you can adjust the set point voltages to suit your needs. It's weak point is the max input panel voltage it can take at 42Voc, so you can't use, say two 120w 12v panels in series as your one 24v panel (that would be two 22v Voc so 44v and over the 42. No problem on a panel with Voc about 37v like a single 24 like my Hanwha 230w.
A better choice to get more input voltage might be the Tracer 20a MPPT at 100Voc limit. ($140) We are waiting for a report from a member who got one of those. I saw one Youtube video on it from Oz where he seemed to say it has the high set point at 14.4v but I don't know if that is adjustable if you wanted higher.
In Key West it may be that 14.4 is plenty high for the prevailing temperature, don't know.
