Even for those who are practically swimming with money, power bills are still a huge concern, particularly with large homes that have plenty of rooms and appliances. With Tesla’s Powerwall, this could become a much smaller issue, with savings potentially amounting to 92 percent of what homeowners would usually need to pay.
Nick Pfitzner is an Australian homeowner who was one of the first to install a Tesla Powerwall in his home, Futurism reports. This is basically a lithium-ion battery pack that is also equipped with a solar array capable of producing 5kWp of energy. It even has a SolarEdge inverter, as well as a Reposit for monitoring the whole setup.
Before Pfitzner installed the pack, he was at $572 in electric consumption for one-quarter back in 2015. By 2016, that number went down to $45 in the same time period. On top of the huge savings that he made, he was even eligible for a $50 credit for those quarters when the power that he didn’t use was given back to the power grid. Basically, Pfitzner made money while also saving money.
Choice recently had the chance to speak to the homeowner who explained how he managed to reduce his power consumption and expenses by such a huge amount. Pfitzner made it clear that it wasn’t without some effort, but that the reward is undeniable.
"Before I crunched the numbers I was looking at what would be my return on investment. If it saved me 80% of my power bill, [I thought] it would be pretty good," he told the publication. "I really learned a lot about myself and how my house uses energy and how we can improve with solar now.
“The system will power whatever the house needs first as a priority, then it will fill the battery as a second priority and then anything over it'll export. The aim is to try and export about three times of what I import because my electricity cost is about three times [as much]."
