Solar PV Powered Cold Storage System is a cold storage facility for storage of fresh horticultural produce, powered by solar photovoltaic with battery backup. The puff insulated walk-in type cold storage chamber, constructed and fitted with a vapour compression refrigeration system and a humidifier. Temperature and relative humidity controllers are fitted in the cold storage chamber to maintain desired room temperature (5–25°C) and relative humidity (65–95 per cent) for storage of horticultural produce. For operation of the cold storage unit, solar photovoltaic (PV) power plant and minimum battery backup are required. The battery backup is provided to store solar power generated during the day and supply power during night and cloudy weather. The lead acid solar batteries are used for storage of power off-sun shine operation. Energy output from the solar panel plant is sufficient to operate the cold storage unit. The power conditioning unit/inverter of the solar power plant converts the DC power produced from the solar panel into three phase AC electricity for operating the cold storage unit and other utilities.
