PV Solar panels are made up of photovoltaic cells, that contain semiconductors such as crystalline silicone. When these materials are exposed to visible light, they create an electric current which is captured and converted into power that can be used by normal house holds. Queensland has some of the best solar resources in the world and while small scale, rooftop solar is very popular, Utility Scale facilities are still growing. There is approximately 200MW of Utility Scale Solar operating in Australia. This industry is expected to expand rapidly in the coming years as PV technology improves.
Power storage technology has the potential to revolutionise utility scale renewable energy as it will enable electricity to be released to the grid during periods of peak demand and in the case of PV Solar, at night when the facility is not generating. There are two technologies which are being assessed for the Yarranlea Solar project, Lithium-ion and Zinc Bromide Flow batteries. A final decision on the technology type will be announced as the project is developed further.
