In January 2020 we installed 6.6kV solar system including data monitoring. Using our own energy e.g. switching the heat pump hot water to daytime, reduced our network energy bill to around $600.
In January 2021 we purchased a EV, so we now have transport costs added into our household energy costs. It costs about $5 to fill an EV “tank”. Of course car charging is free using our solar, as shown to left with our solar following car charger.
In July 2021 the solar feed in tariff reduced from 9c to 6c per kWh, so the saving against consumption tariffs is worse. More than ever the incentive to use our own energy, maybe it is time to investigate a home battery?
