Solar thermal cold storage for 24x7operations using thermal storage Cold Room PCM Storage Gassifier based hot water generation 24*7 Operations by Solar Thermal Backup of gasifier incase Of solar deficiency Gasifier as back up to Solar Hot water Generator. Backup becomes active when the hot water from solar is not at 120 deg. C, or when the cold storage is required when Sun is not available.
