Tesla Powerwall pays off, Aussie home powered for just A$0.46c per day

Remember Nick Pfitzner of Sydney? 4 years ago he was the first person in Australia to add a Tesla Powerwall. The goal of adding a battery can be different for different people, but ultimately the biggest benefit is a financial saving as a result of storing the energy captured by the solar system on your roof, and using that energy in your house, time shifted to when you need it.

Today, Nick Pfitzner along with Australia’s largest solar and battery installer, Natural Solar, can reveal the savings achieved over the past 4 years. The Pfitzner family leveraged their Tesla Powerwall system to save a whopping $8,463.42 on the price of their power over period.

This translates to a massive $2,115.86 average saving each year on household electricity bills, and has managed to power his home for just 46 cents per day.

By leveraging solar and battery, Nick and his family have been able to live their lives, using air-conditioning, electricity and appliances as normal, while making a big financial saving on their power bills, all while helping the environment.

“For many families, these results sit firmly in the ‘too good to be true’ realm.

Nick was one of the first people in the world to have his Tesla Powerwall installed, and effectively started what we term the ‘battery boom’ globally. To see the numbers stack up after four years proves the technology is truly here to stay and will likely only continue to grow with a huge demand worldwide.”

Chris Williams, CEO & Founder of Natural Solar.

Before installing their first-gen Tesla Powerwall and 5kW solar system, the Pfitzner family were previously paying an average of $572.29 per quarter to power their four bedroom home with an internal laundry, air-conditioning, state of the art appliances, a pool and outdoor entertaining area.

For the past 4 years, the Pfitzner household has seen a drop in their average quarterly price of power by 92% to just $45.16 per quarter. Some quarterly bills have seen the Pfitzner family pay just $19.47 to power their entire home for the entire three month period.

“When you crunch the numbers, it’s astonishing to see the real time, real life savings. For the full four years, the Pfitzner household has only paid $677.34 to power their entire home – their quarterly electricity bills used to be just $105 less than this.

When the price of power is increasing by an average of 10%-15% per annum, these unprecedented savings really speak to the benefits of battery power. At Natural Solar, we are seeing most of our customers that install solar and battery storage in their homes experience a reduction in their power bills by up to 90% and like Nick, have an ROI period of just 7 years.

The Tesla Powerwall has truly unleashed savings that many sceptics never before thought possible. In thecase of Nick Pfitzner, he is the first in market case study to reveal the long-term truth about how the financials stack up and the one the world will watch for years to come.”

Chris Williams, CEO & Founder of Natural Solar.

Since this initial high profile battery installation in January 2016, Natural Solar has seen the demand for battery storage truly skyrocket. Natural Solar has received more than 425,000 consumer enquiries for battery power, and has installed thousands of battery storage systems in houses around the country.

These results are relevant on a global scale with a 15,000% worldwide increase in home battery installations in the past 4 years.

    AWESOME! This article makes me both smile and cry. I love the fact that batteries are so effective for load shifting in combination with solar systems and I cry because our house is too shaded by trees to allow for a meaningful PV installation.

    He must be constantly getting refunds if he’s only paying 46c per day, because the daily supply charge is more than that.

    It’s very wrong to claim that the Tesla Powerwall did all the savings. No, the solar panels would have done most of the heavy lifting in terms of cost.

    The only part when the Powerwall saved money is when the solar system production drops off early in the afternoon, evenings and early in the mornings. They need to calculate that bit.

    In fact, on the Tesla App, it will break down how the energy was distributed. It will clearly show how much was dispersed by the Powerwall, Solar Panels and Grid.

    I know, I have one. For the last 12 months the Tesla Powerwall provided, the following figures:-
    21% of the energy for the house came from the Tesla Powerwall.
    54% of the energy for the house came from Solar Panels
    25% of the energy for the house came from the grid
    About 95% of the grid energy was ToU off-peak rates at 15c/kwh. (which most of it went towards hot water heating and the heat banks in Winter). Most of the grid energy was consumed between May and September during the Wintry months and low solar production. Grid energy consumption between September and May (Spring/Summer/Autumn) is sub 100kWh.

    Total house energy was 7946kWh for 2019
    So, the Tesla Powerwall provided 1668kWh (at an average of 32c/kWh), this is about $533
    Solar Panels provided 4290kWh which is worth $1373, nearly 3x what the Powerwall provided.

    So, there’s no way the claim the Tesla Powerwall did the bulk of the savings.

    But, I’m not concerned because there are other benefits that the Powerwall provided. Backup power. I had 84 blackouts lasting a total of 104 hours. So, it’s done its job in that respect. And to keep the solar panels going in the event of grid outage during the day which it’s done a few times.

    To report that the Tesla Powerwall (or any other battery systems) does the bulk of the bill savings is and will be a total lie. Because without solar, the battery alone will never make financial sense. Until one has access to ridiculous ToU rates where off-peak tariff is extremely low in value compared to Peak tariff to take advantage of arbitrage.

    Please report the real figures what the Tesla Powerwall did for the Pfizers. This is just a misleading headline grabber.

    I have a Tesla Powerwall 2 (14kWh battery), compared to the Pfizer’s PW1 (7kWh battery)
