Getting cheap solar panels

Used solar panels are ideal for us. There are a few places to get them

  • Used-Solar has an ebay shop. They ship panels, or you can pick them up in Leipzig. We got our panels for CCCamp19 from them
  • SecondSol is an online market place for used and new solar gear
  • eBay & eBay Kleinanzeigen

Charge controllers connect the solar panels to the battery (and sometimes also to the load). There are cheap ones from China that work decent enough, and proper expensive ones. Also, there are OpenSource projects.
