I had a relapse yesterday and picked up another 20 solar panels at restore. 275 watt LG panels at about $30 each. Now I’ve to about 75 used panels. I hope to deploy about 50 before it warms up in May.
I’d appreciate any tips for testing solar panels. I plan to test open circuit voltage, short circuit current, and current at max power. Those that pass will be put in the deploy pile and if they fail, I’ll put them in the diagnose and fix pile. My plan is to set up a stand where I can put the panel up, hook it up via mc4 connectors and have a battle born and little charge controller.
Two questions, I am planning to use my clamp multimeter. Or is there a little gizmo that will test all at once? I’d like to make this as easy and quick as possible.
Second, is there anything else I need to test?
Thanks
