Solar Performance - March 2016

This year March did reasonably well, falling slightly short of expectations but lagging noticeably behind last year. My system produced 227.47 kWh this month compared to 262 kWh last year. The estimate for the month was 236 kWh.

Compared to last month, however, things look a lot better. Production nearly doubled from 126.45 kWh to 227.47 kWh, resulting in a nice surplus that I sold to Seattle City Light.

Perhaps some of the shortfall can be traced to March 3rd, when my inverter decided to take the afternoon off. It's since been replaced (thanks, warranty!).

Looking at the individual panels, A6 is continuing its strange trend of having one bad day every month. Luckily it picked one of the cloudier days to have a problem this time.
