The analysis indicates the Virtual Power Point (VPP) largely performed as expected, with solar generation during daytime hours more than sufficient to meet household and business load on average resulting in export of excess solar to the grid. At sites with batteries, batteries were charged during daylight hours and discharged during the evening and morning hours, and the effect of the tariff structures implemented during the trial is clearly shown in the output data. VPP sites typically exported more energy to the grid than was imported on any given day, although some days, especially in low irradiance and cooler conditions, had a net import of energy.
