Solar Power Production Tracker

I’ll try to keep this page updated every month with our solar power production and compare it with the PVWatts estimate of expected generation. For more details about our solar system (6.93kW of panels, 6kW inverter), visit my blog post about finding solar installers in Charlottesville. For a more detailed financial analysis of solar production in Virginia, see my post on that at my other blog. There is a slight discrepancy between the solar inverter numbers and the dominion solar generation meter, which also I’ll keep track of.

Year\Month Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec
PVWatts Estimate 505 425 675 695 742 689 705 661 581 731 473 490
2014 (Inverter) 279 850 928 941 928 794 705 651 527 472
2014 (Meter) 277 847 923 936 923 790 701 648 525 470
2015 (Inverter) 490 622 714 909 1010 809  841  888  691  672 526 373
2015 (Meter) 489 619 711 905 1004 804  837  884  687  669 523 372
2016 (Inverter) 500
2016 (Meter) 498

April 2014 was the first full month of production.*System went live March 19. So March 2014 production numbers represent a partial month.

Cumulative Power Production as of December 31 2015: 16120 kWh at inverter (16043 kWh at solar meter)

  14. I assume the picture of the solar panels are the ones on your roof. Been a few years since there was snow in Houston. Remember that day cause, I was a substitute teacher at Pasadena High School and the kids ran out of class to have a snowball fight outside.

    Kids will be kids.

  15. Yeah they are the panels on my roof. Snow is fun, especially if you only get it one or two times a year like here. That picture was taken just a few days or maybe weeks after the panels went online.
