A gift of 2 panels that were otherwise going to the dump

They were going to be dumped because the glass has been badly cracked, but they’re at our place now. 

As they are, not cleaned they sit in the morning sun producing a little over 40V at 2.5 A. That’s enough for my little cobbled together system. Just need to work out a way to step down from 36 V to 12V.
