Great info. Thank you for the post! Sounds like I’m going to have to test each panel individually at some point. I got them for so cheap I’m pretty happy they work at all.
Here’s a breakdown:
2x four panels in series with those two connected in parallel. Interestingly each series of panels perform (or underperform) equally. While everything is connected (on this particular day) I’m getting 92/100 volts under no load, 6/8 amps per side and 65/80 volts under load. It’s consistent that my voltage goes down under load and the higher the amps, the lower the voltage. It’s worth mentioning that I have a 100’ run of 10 awg from the panels to the SCC. I measured the voltage drop under no load it was 1.5%.
I’m guessing I should measure the voltage drop under load. I haven’t don’t that yet.
I used 14 gauge connectors between the panels, 12” only. Could that be limiting my flow?
Still got some work to do
