Potential of solar energy contribution in Queensland

Abstract

The analysis aims at identifying the potential of solar energy, grid-connected photovoltaic (PV) and solar thermal, contributing covering day-time peak demands in Queensland (Qld) Australia. Given the high demand for air-conditioning and industrial activities, this study shows the ability of solar energy to satisfy those diurnal demands achieving a moderate load profile and improved economics at lower energy cost. Further more, the solar energy being located on site offers the advantage of avoiding transmission losses and voltage drops throughout the network. Life-time energy cost calculations for solar equipment indicate the ability of the solar system to provide competitive prices to cover demand peaks. The research incorporates grid-connected photovoltaic and evacuated tube solar water heaters in order to cover electrical and thermal loads respectively. The results quantify the power able to be waived by using solar systems in Qld.
