The system is described by its creators as a cost-effective solution for water heating by storing thermal energy in fine sand. Techno-economic analysis indicated the system is economically viable for domestic water heating applications, with an initial capital cost of $278 and an expected lifespan of 25 years. Researchers from India's National Institute of Technology (NIT) Kurukshetra and the National Institute of Solar Energy (NISE) Gurugram have developed a PV-driven prototype solar geyser system that uses a fine sand thermal storage medium for domestic hot water. The Fine Sand Solar Geyser ...Den vollständigen Artikel lesen ...
