Abstract

This research is handling the contribution photovoltaic (PV) and solar water heaters (SWH) might offer to mitigate peak electrical demands in Queensland. Given, heavy electricity peak demands manifested in strong electricity price fluctuations, with a range from $20/MWh to more than $2000/MWh for short period, it is generally accepted that electricity peak demand must be satisfied at a particularly elevated energy cost. High demand in Queensland for air-conditioning and industrial activities makes solar energy contribution not only viable, but also economical. Besides covering demand peaks, the solar system – being located on site – offers the advantage of avoiding transmission losses and voltage drops throughout the network. Life-time cost calculations for solar kWh indicate the ability of the solar system to provide competitive prices to cover demand peaks. The project incorporates a 1kW (peak-power) grid-connected photovoltaic and a 1.37m2 (collector area)
-120Litre (storage tank) evacuated tube solar water heater SWH unit. The results quantify the power able to be waived by using solar systems in Qld.
