Checking In with the Performance of our Net-Zero Utility Cost Home in Northside

Potterhill Homes completed a new model home in June of this year that, in theory, would be our first ever Net-Zero Utility Cost demonstration home.  It’s truly an R&D facility to test the benefits of combining solar panels & geothermal heating with our standard Potterhill energy-saving features.

The home’s estimated annual utility bill, as provided by a Home Energy Rater, is $855 per year.

Since the home has 3 KW solar panel system, it will receive approximately $900 each year in income from the sale of it’s Solar Renewable Energy Credits.  So, not only does the home’s utility bill benefit from the solar panels, but the production of these invisible, digital certificates called Solar Renewable Energy Credits actually cause the utility company to pay us for the solar production.

So, let’s look at our Year to Date utility bills, and compare that to the income we’ve received from the sale of our Solar Renewable Energy Credits:

As the chart shows, we have paid Duke Energy a total of $306.95 from June-November 2010, and we have received checks in the amount of $606 for our Solar Renewable Energy Credits produced by the solar panels.

The bottom line? From June through November of 2010, our R & D house is $233 ahead of Duke Energy.  In other words, if we sold the house today, we would have received $233 more in SREC checks than we paid out in utility bills.

So far, this house is out-performing our expectations.  Now we’re going into the coldest, least sunny part of the year, so let’s all keep our fingers crossed that we don’t get too far behind this winter.

Our theory is that by June of 2011, our 1 year Net Energy Bill will be $0.  All of the numbers are pointing in the right direction. Stay tuned!
