Note: I’m 6 months behind in finishing this update. Back dating the post to January 4 when I statrted it.
Last year we had relatively normal usage and rather low solar production. This year we have slightly less than normal solar, but higher usage. The end result is our second net overage in the lifetime of the house.

We produced 5% less solar than average, and used 14% more than average. That tipped the scales once again, just enough to push us into the negative zone. On the long view however, we’ve still generated a surplus of 9,040 kWh over the last 8 years since the house was built.
We were performing fairly normally until September. Let’s break down the numbers.
Q1 2019 summary: 6% colder, 14% more usage and 16% more sun as compared to Q1 2018.

2018 is the first year we have not generated a solar surplus. In short, we produced 15% less solar than average, and used 5% more than average. That tipped the scales just enough to break our 6 year net zero running streak. On the long view however, we’ve generated a surplus of 9,157 kWh over the last 7 years since the house was built.

Nothing exciting to report, which is normal for 3rd quarters.
At 7am on July 15th we became net positive for the year. As of the end of September, we have a surplus of 1,115 kWh heading into the final months of 2018. That’s about 211 less kWhs than last year at this time. Overall for the year, our solar production is down about 7%.
