I posted a progress report back on August 20th showing our 183 kwh credits with the power company. Yesterday, Sept 10th, I took the above pic showing us with 333 kwh in the bank only 21 days later. What helped us to pack it on was a change in the weather pattern to dry clear days. We have been producing 20 to 22 kwh on most days for the past two weeks. Another important factor was that we were away from home for 10 days thus reducing our demand. It's these kinds of circumstances that can gang up to produce twice what you expect. Then there are the times when things gang up and disappoint.
When living with solar, you'll have your ups and downs on the short term. We calculate future production with the solar aperture and long term climatological data for the site.(plus other things) For sure, the slate gray skies of winter will be a bummer, but you'll be prepared with hopes of near term improvements.
Back on the August 20th post, I mentioned we were running behind due to a cloudy pattern that month. Our prediction was for 497kwh and the partial month's data suggested 446kwh. What we actually closed with was 476kwh. We'll take that.
If September's weather stays the same we could see near 600kwh for the month. Of course, by then we would be in drought conditions, not good.
