These panels are brand new with full warranty, this model was being phased out. They are located at my warehouse in Mansfield, TX. I have 72 panels as of now (8/24/23). They do have transparent back sheets so there is some benefit if you can get some light bouncing off the ground onto the back of the panel for additional output.
I can freight if you need at least 10 panels, send me an email and I can get you some numbers.
