Solar thermal energy (STE) is a technology for harnessing solar energy for thermal energy (heat). Solar thermal collectors are defined by the USA Energy Information Administration as low-, medium-, or high-temperature collectors. Low temperature collectors are flat plates generally used to heat swimming pools. Medium-temperature collectors are also usually flat plates but are used for creating hot water for residential and commercial use. High temperature collectors concentrate sunlight using mirrors or lenses and are generally used for electric power production. STE is different from photovoltaics, which convert solar energy directly into electricity.

Building an economical and competent resource for energy storage, plays a key role in energy conservation as it can cut down the time radically, for both energy supply and energy demand. This innovative concept as crucial as locating fresh sources of energy, can actually enhance the output of the whole energy system there by escalating its consistency.

In phase change materials (PCM s) like the salt hydrates, paraffin s, non-paraffin s and eutectics of inorganic, the storage of solar heat energy, leads to compactness and delivering of heat energy at steady temperatures.
