Yesterday I learned a lot about the HERS classification for energy efficiency in homes. What I learned was that the score of "100" meant that the home met the 2006 standard for energy efficiency.
That standard is 20 years old. Basically any new home built to today's code blows that away and should easily score a 70 or less.
The Off The Charts Pinnacle is to get to "NET ZERO" which is defined as a home that produces 100% percent of its energy needs from renewable sources.
However, Net Zero can be obtained by purchasing enough solar panels that during the day your home produces an excess that is sold back to the utility company at less than wholesale (long story) and then you buy back the electricity that you sold as less than wholesale for retail.
BUT, if you have a battery backup that your solar panels charge during the day, it will provide you with electricity during the night . . . . to a point due to the costs of the battery backup being so prohibitive that most consumers only have enough for a few hours and then the system switches back to the grid or a generator.
Again, BUT what if the consumer just doesn't want to buy any electricity or next to zero year-round?
Enter my client who just installed a system on his property and started it up a couple of weeks ago and even though he has a fantastic large luxury home, a huge air conditioned workshop, charger for his EV and lots of goodies, the system barely utilizes its capacity to produce electricity once the huge battery backup has been charged.
And this place can be yours for a fraction of what it would cost to put together today.
