There is a hidden advantage to leaving town for thirteen days in July: your solar PV system can just crank electrons back into the grid. Check it out:
A total of ~1.15 mWh produced for the month. Yep, that is more than a megawatt of clean energy from the sun. It was also just under the prior month’s ~1.2 mWh of production, but also good for the second best month of production in my system’s history.
In terms of electricity production versus consumption my household ended up “in the black” ~466 kWh.. For the year so far we flipped to being “in the black” by 366 kWh. As a side note, we also flipped back to being net positive since our new meter was installed about two years ago.
In the chaos of getting ready to leave for almost two weeks I missed recording our last billing cycle’s natural gas consumption. I remember it actually being higher than the same period the prior year, which makes sense given we were gone for two weeks in June 2021. I will rectify the numbers next month.
For the month of July we drove the Nissan Leaf 628.9 miles at an average efficiency of 6.2 miles per kWh. This works out to a CO2 avoidance of ~737 pounds versus my truck assuming we pulled every watt for the Nissan Leaf from the grid at an average carbon intensity for my region. For the year so far we have avoided ~5,051 pounds of CO2.
