Solar energy is used for various purposes in New Zealand (EECA, 2012).
The solar energy is used to warm water through various designs in buildings that capture and store the heat energy. Solar energy is also used to generate electricity with Photovoltaic panels that act as the semiconductors for the generation of electricity. Other concentrators of solar power technologies use mirrors for the focusing of thermal energy. There are turbines that can also be used by being turned by super-heated steam in order to generate electricity.
