After months of trying to get an electrician out to troubleshoot my rooftop PV system, I have one scheduled for Monday. I'll give it 50-50 odds that he'll show up. Tradespeople on Kauai have more work than they can handle so it comes down to connections & luck. All of the solar installation companies I contacted just want to sell me a new system.

Anyway, it's so weird to see the east array producing almost nothing in the morning. (It's 9:30 am here.)

Is the east array connected in series? Can you try connecting them in parallel, or make more parallel connections and divide the series?

One dead or partially shaded panel in a series can ruin the whole series.
