We went with AM Solar in Springfield Oregon. Four panels on our motorhome. Works pretty well. Next move is to upgrade our 4 AGM batteries to Lithium! Just have to wait for that winning lottery ticket!
I have a 100w panel on my rv with 2 ea. 6 volt golf cart batteries and never have ran then lower then 2/3 and we have regular light bulbs with my wife running all of them damn near. Lol It only takes maybe an hour or 2 before it says full charge when the sun comes out.
