I have at least four 345 W 48 V solar panels for $250 each. I do also have a charge controller that could be purchased separately. These are not cheap solar panels, and have a lot of life left in them, there are approximately 6 1/2 feet tall, as you can see by the specs, even though they’re aluminum the weigh just over 50 pounds apiece. The complete unit would be great for off grid cabin, I used it with four storage batteries.
