World's first Tesla Powerwall is paying itself off much faster than expected

Four years ago, Tesla installed its first ever Powerwall battery pack in an Australian household, and now the residing Pfitzner family has revealed just how much of an impact the energy-saving measure has made. When combined with a solar panel system, Powerwall allows users to store any excess energy generated by the panels in order to use it at times when the sun alone can���t provide the necessary power. While this effectively allows a home to operate self-sufficiently, there is a still a need to rely on the main power grid when the battery depletes due to extended periods of inclement weather or similar. As for the environmental impact – the ability to store reserve energy in a battery pack has the potential to reduce household carbon emissions by up to 6 tonnes per year, which would be a significant figure if the technology was installed in masses of homes.
