One of the major requirements with the net zero home was the use of the (PV) electric solar. The concept is very simple in my description. The solar panels track the sun from sun up to sun down with a photo eye. Inside the home we do not have batteries lined up, but instead the power produced goes directly back into the electrical grid. The power used is bought at 9 cents per kWh and power produced is paid back at a rate of 30 cents per kWh.
I have to admit that when we started this I questioned (PV) electric solar, but after the panels went in it really motivated me. I started doing things different at home and in our office. I believe that the opportunity is huge for (PV) electric solar and I can't wait to see the solar panels dancing with the sun.
