MY FIRST NET ZERO ENERGY DAY!


In red shows my net zero day

As you can tell from my ALL-CAPS title, I'm a little excited by this.  I've had my solar panels for over a year now and I've never come close...although I really didn't expect it.  So why now?  Well, my wife and I were away in Charleston attending the Cooper River Bridge Run.  The thermostats were in vacation mode, so the house wasn't being heated so that helps.  And without water usage, the water heater didn't need to operate (maybe a little, probably).  So really, the only operating were my normal household loads (HTPC, fridge, freezer, kegerator, clocks, etc).  And apparently it was a nice sunny day (as seen in the pic below) where we got a great amount of solar generation.

Hourly power consumption for the Net zero day.  
Looking at my TED5000 data, my empty house consumed 9.9 kWh, while the solar panels generated 10.6 kWh.  Yes, this doesn't add up t the -0.6 kWh shown, but I'm guessing there's some rounding going on that we can't see unless I download the full data (which should be in watts, not kW).

Still...I'll take a Net Zero Energy Day...well, TECHNICALLY a Net POSITIVE Energy day...
