The Pfitzner family have received their first quarterly energy bill since Natural Solar installed their Tesla Powerwall and solar system in January 2016, with the price for their power plummeting from $660, to a mere $40.46 in energy charges.
That’s a payback period of an extraordinary 6-7 years on the system.

Speaking to Gizmodo, Managing Director of Natural Solar Chris Williams said that they knew the result would be good. “But having the data to back it up just cements it for us.”
“It’s extraordinary to see such a significant decrease for the Pfitzner family and clearly demonstrates why we are experiencing such strong demand for our home and commercial battery storage solutions.”
Williams describes the Pfitzners as being energy conscious customers. When speaking to Nick Pfitzner he revealed that he simply does “the standard things anyone would do when having a solar system installed”.
The functionality of the Tesla Powerwall is simple, with this device storing solar energy during sunlight hours allowing homeowners to use it at night, avoiding the need to sell excess energy back to the grid. The Powerwall, which carries an impressive 10-year warranty period, has such a range of new and varied functionalities.
Based in Sydney’s Hills District, the Pfitzner family home includes four bedrooms, internal laundry, a pool and outdoor entertaining area.
Their personal renewable energy solution includes the Tesla Powerwall, an array of 5kWp of solar panels, a SolarEdge inverter and fully integrated, bi-directional cloud-based monitoring software to see the direct output of energy from the entire system and the Tesla Powerwall.
The family “schedules everything” so as to preserve the power stored for nighttime usage. Devices are run during the day, the dishwasher in the morning the pool pump in the afternoon (and not at all if it’s cloudy). Oven use isn’t limited, though. “My wife is a great cook,” Pfitzner laughs.
Williams says the Pfitzner family have revealed to the world the massive impact the Tesla Powerwall combined with a full solar solution can have on both the environment and their hip pocket, paying an average of just $0.59 per day for their power.
“The utility companies will be hurting from this disruptive technology as it puts the power back into the consumer’s pocket and we now have data to support the benefits,” added Mr Williams.
Williams describes this result as one of the first in-market experiences that shows the Tesla Powerwall in action.
“Consumers have been drawn to the Tesla Powerwall as it represents energy independence, and they want to know what the real life return on investment would be for solar and a Tesla Powerwall,” commented Mr Williams.
“In this case, should energy consumption remain at a similar the Pfitzner family should expect to see a complete payback period of between 6-7 years, whilst also having a positive impact on the environment and adding considerable asset value to their property.”
The Pfitzner’s 5kw array and 7kw Powerwall Battery system cost a total of $14,999, after a $3,900 rebate — which is claimed by simply signing a form, not by being out of pocket at any point. Full Tesla Powerwall and solar panel solutions from Natural Solar start from $13,590.
