My solar monitoring platform was available for an entire month and all of the panels on my solar system were fully functional. This led to a pretty good March for solar production:
Just under 578 kWh for the month. This compares with ~316 kWh in 2019 and ~424 kWh in 2018 or an increase of ~83% and ~36% over each of those years respectively. My guess is that the average year-over-year production increase will fall somewhere in the middle of those two on average over the course of the next year. Only time will tell.
For the month, my household ended up “net positive” ~67 kWh. My household was also “net positive” in March. It is my assumption that the next couple of months will be big “net positive” months in terms of electricity consumption versus production since the period before the hot summer months is generally light on consumption.
One factor driving a lower level of electricity consumption is the fact that we are not driving much, if at all, as a household due to COVID-19. All of my children’s activities have been cancelled and we are working from home. I cannot remember if I have charged my Nissan Leaf in the two weeks we have been home from an aborted spring ski trip to Colorado.
For the month, I drove my Nissan Leaf ~652 miles at an average efficiency of 5.3 miles per kWh. Almost all of those miles were in the two weeks before we locked down at home. I “saved” ~746 pounds of carbon dioxide emissions compared to driving my truck assuming that I pulled all of the electricity from the grid at my utility’s average carbon intensity. In the first quarter I have “saved” ~2,785 ponds of carbon dioxide emissions. Given that I am now producing more electricity via my solar panels than my household is consuming, including EV charging, those carbon dioxide savings are even greater. The same logic goes for the fuel cost savings.
April is going to be a weird month for sure.
