I have been researching expandable solar power systems and have a few questions for anyone who is familiar with them. If I'm understanding correctly the order the equipment goes is ... Panel to disconnect to charge controller to monitor to batteries to inverter to grid panel box or extension...

I got these: Got 5 of em, they say 20 watts each, an 1.22 Amps. Now I just gotta decide what to do with them. Could use em on the motorhome er put in a small system here at the house. Don't now which yet. Be nice if I can get a few more from work.
