This data-file is based on actual power flows, kindly shared by a client of Thunder Said Energy, who is based in sunny Australia, with 13.5kW of residential solar panels and the 13.5kWh Tesla Powerwall system as a back-up.
It includes 5-minute by 5-minute power flows, over the space of a week in summer, from which we have imputed solar generation, direct consumption, battery inputs, grid exports, later battery drawdown, final power consumption and grid draws.
Daily average data are also drawn over the space of a year, to get a longer-term perspective, including variability by season.
This system is supplying an impressive 92% of the house’s year-round power needs, although interesting debating points are whether the system is ‘efficient’ and how to use large volumes of excess power if the grid becomes saturated.
