May totals are in

Well, the May totals are in, and it looks like there may be an issue. According to the Generated vs Expected chart, I was supposed to hit 930 KWh of solar generation in May.  However, the total generation was only 831 KWh.  I don't think the weather was a major factor, as there were only 2 days of sub-par generation.  On May 3rd, the system only generated around 11 KWh, and on May 26th, it was 16.5 KWh.  Otherwise, no day in the month yielded less than 22KWh or more than 31 KWh.  May 5th was when the system peaked at just over 30 KWh for the day.  The system is designed for 5.6 KWh max, and it looks like the most I am ever seeing is 4.5 KWh instantaneous power.  I called my contact at Real Goods, to ask about why it is generating less than expected, and it looks like they will need to send someone out to check the system out and see what is going on.  I'll see what they find.
