Tesla & solar installation

What an awesome project to work on for the team! We combined 68 SunPower Performance 3 SPR-P3-370-BLK panels with multiple Fronius inverters and 3 Tesla Powerwall 2 battery systems. 


Self-consumed energy:
CO2 reduction:                     21 tonnes CO2



Estimated lifetime savings: $133,612 
Solar export earnings p.a: $1,481 

SOLAR STORY: Doncaster, Victoria

Our aim for this Doncaster solar system was to match the consumption of the household with sufficient solar capacity to meet the everyday needs, while also providing the opportunity to use solar energy overnight with the use of the Tesla battery system. 

The solar consumed figures outlined above show the clean energy supplies to meet as much of the daily energy consumption as possible. 

Dunton Group specialise in designing and installing solar systems for maximum energy production to offset your consumption.  

Annual Savings

The pre-solar annual energy bill was approximately $7,520. With solar and battery storage the bill is estimated to be reduced to a credit.  

Environmental Benefits

The solar system installed by the Dunton Group has enabled this property to reduce 21 tonnes of carbon dioxide. 

Solar Export Earnings

At peak production times the solar system produces more energy then the household can consume. The additional energy produced will be used to charge the Powerwall 2 batteries and anything additional can be sold back to the grid with credit expected. 

Self Consumed Energy

With the installation of this solar and battery system this property will be expected to be using at least 87% self consumed energy.

Product Features

For this solar installation we have opted to use a Fronius-Symo 15.0-3-M, Fronius Primo 5.0-1 inverter combined with 68 SunPower Performance 3 SPR-P3-370-BLK solar panels.
