I have run a PVWatts calculation for my system, entering all of the specs and choosing weather data by double clicking on the map to get the proper rectangle see attached. PVWatts calculates a production of 11,195w but on my electric bills for the past 12 months, I only totaled 4,182w in production?? I know that my inverter was misbehaving and clipping at 5 kw instead of 6 kw until today but that would not explain such a huge difference. It was probably only clipping for 2-3 months at the most. Any idea why such a huge difference? Since I just got online about 1 wk ago, I don't have independent historical production data but my daily productions on PVoutput.org and SE Monitoring site the past week have been at or below my average daily production for this month last year.
