The past month was surprisingly similar to the same month the year prior:
Almost 416 kWh of clean, green electricity from the funky yellow sun. All in, including 100% of my EV charging needs, I ended up down ~122 kWh for the month. The weather was schizophrenic this month bouncing from cool fall weather to hot and humid. The third week of the month felt like the dog days of August with 90 degree temperature readings and similar humidity levels. Needless to say, the air conditioning got turned on to cut that down a little bit. Until that point I was running ahead in terms of production versus consumption.
For the month I drove my Nissan Leaf EV 755.1 miles with an average efficiency of 5.9 miles per kWh. For the month I required ~128 kWh of electricity for my mobility. Compared with the F150 that the Leaf replaced, I avoided emitting ~879 pounds of CO2 into the atmosphere assuming that I drew electricity from the grid at an average carbon intensity for my region.
For the first nine months or so of the year—my Leaf arrived the second week of January—I have driven a total of 5,893 electric miles at an average efficiency of 5.2 miles per kWh. The total C02 emissions that have been avoided versus the F150 that the Leaf replaced are 6,733 pounds thus far. Again, this assumes 100% of charging occurs from the grid with an average carbon intensity for the region.
Interestingly, the total amount to charge my Nissan Leaf for the month–~128 kWh—was about how much I was “down” for the month in terms of solar production. This aligns with my original estimates where my initial sixteen panel PV array would provide ~100% of my electricity needs.
As the weather turns cool and the pumpkin spice flows freely I am waiting on an install date for the solar array expansion. The plan is to add 8 360 watt panels to my existing 16 290 watt panel array. This represents a ~59% increase in solar capacity and given the new panels will be on the same azimuth it should represent the same amount of increase in terms of actual production.
The increase in solar array capacity should account for more than 100% of my Leaf’s charging needs and provide a cushion of excess production for additional electrification. The future is electric.
