I only have 3 panels left, in very good condition, $50 each, buy one or all 3. 36 volt DC current output can easily be converted to a 12 volt system using a cheap step down transformer. You will need a truck or trailer. Calls only, texts will be ignored. Also listed in "general for sale", please go there to see photos. I started with 40 panels and these are all that's left so don't wait. 1st come takes them.
