First Official Day of Solar

Here's the graph from our first full official day of solar energy generation. Note the two colors show the output from the two different inverters. The panels attached to one of the inverters goes into the shade pretty early in the afternoon. If I trim some of the neighbor's trees then we could get the yield up a bit more.

And here is a graph from PG&E showing how much electricity we used over the last couple years. It seems we use close to 1,000 kwh per month. The panels are putting out a bit more than that right now, but will generate less in the winter. Of course when the Tesla arrives, we'll be using a bit more electricity, depending on how much I drive it.
