Third quarter 2017 performance

Q3 2017 summary: 33% cooler, 9% more usage and 7% less sun as compared to Q3 2016.

This is part of our quarterly home performance reporting. All data is posted at netplusdesign.com

Nothing exciting to report, which is normal for 3rd quarters.

At 1pm on July 17th we became net positive for the year. As of the end of September, we have a surplus of 1,326 kWh heading into the final months of 2017. That’s about 574 less kWhs than last year at this time. Overall for the year, our solar production is down about 13%.

Overall, here’s how this quarter compared to 2016.

Water usage was down 6%. Hot water usage up 30%. I think that’s attributable to the chillier mornings this summer.
