The present paper proposes a data-driven analysis of solar pre-cooling and pre-heating (SPCaH) in Australian housing stock. SPCaH is a method to shift peak Air Conditioning (AC) demand to earlier times in the day by using thermal mass of buildings as a thermal battery. In households with rooftop Photovoltaics (PV), there might be surplus PV generation after meeting the household gross demand. The surplus PV generation is usually exported to the grid with a Feed-in Tariff (FiT) cheaper than the electricity retail prices. By implementing SPC/H, the surplus PV generation is stored in the thermal mass as thermal energy during the times with surplus PV generation, and is then discharged during the early evening, when the AC demand usually peaks.
