I'm not sure if this is good or bad news at this point, but the forecast has changed quite a bit. They are now saying the rain here in So Cal should stop by Wednesday morning. iPhone weather is now saying just "partly cloudy" Wed. Thurs. Fri. And then "SUNNY!" Sat. and Sun.
My final energy production totals for today are horrible. Just 930 watt hours (0.93 KWHs) from my 4,800 watt Enphase system, and just 590 watt hours (0.59 KWHs) from my 2,000 watt Victron DC system.
That is a dismal 0.194 sun hours hitting the Enphase panels, and 0.295 sun hours on the Victron DC panels.
This totally nails one thing for sure. The worse the solar power, the better the Victron MPPT kicks ass over the Enphase iQ7 inverters. Even looking at the absolute best production from the SilFab panels on the Enphase system, two of the 300 watt panels managed 64 watt hours, the rest were all less than that, with the lowest at just 42 watt hours. 64 / 300 = 0.213 sun hours on the best panel and 42 / 300 = 0.14 sun hours on the worst one.
The Victron charge controller is doing an amazing job. That is a goofy array with 10 x Newpowa 100 watt panels wired 5S2P running in parallel with 5 more BougeRV 200 watt panels running just 5S. They do seem to work very well together, and I suspect that both cheap panels are using cells from the same source. The difference is the cells in the 100 watt panels are "half cut" versions. Looking at the 200 watt panels, you can even see the marks on the cells where they would be cut to make the half size cells. They are otherwise identical. All panels have the same 32 cells in series so the VMP is the same on all panels. But I still expected the variations across 15 panels to make it hard for the system to pull as much energy as a separate MPPT per panel. And when we have a lot of sun, the Enphase setup does end up winning.
In the race today, the winner was still going really slow.
