Solar Powered Sand Based Thermal Storage Battery System is an innovative solution for storage of heat energy directly from the sun without any need for conversion to electrical energy. This system has been meticulously designed to provide 4-5 hours of power backup in the form of heat energy. The system concentrates the heat energy from the sun in any thermally enclosed box filled with sand. Using sand's property of high specific heat capacity, we are able to achieve the heat energy storage with high efficiency. This system entirely replaces the Kangri which uses coal as a fuel and has a lot of health hazards while this innovative system does not use any fuel and is 100% eco friendly and safe to use. Secondarily, this system is able to generate DC as well as AC electricity directly from stored heat energy using reverse peltier effect which enables using small DC gadgets and AC gadgets as well.
