Solar charging our Volt - free ride!
Filed under: Solar Power, Our Chevy Volt
Posted by: Guy @ 9:06 pm




Below is a net energy chart from MyEragy.com recorded on July 3, that shows the Volt being charged after driving about 25 miles starting from a full charge - so about 7kWh.  Energy below the zero line is being exported to the grid and “banked”, above the line is being imported from the grid.  This shows that our solar array now can provide all the power needed to charge our Volt in the middle of the summer. (The MyEragy site gets it’s data from my TED5000 energy monitor and displays it on the web on a user accessible page).

    Was the charge happening during the day while you were exporting power to the grid?

    Yes, My solar array faces west, so solar maximum is around 3pm. The Volt was charging from about 1:30 to 4:00pm during the peak output of the solar array. The parabolic curve in the bottom half of the chart is the sun’s energy changing as it moves over the solar array. You can see more about my solar installation here on my site.
