Standard mounting brackets are reserved on the side walls and roof of the intelligent cultivation container. Customers can optionally install solar PV modules according to local sunlight conditions and power consumption demands. Equipped with dedicated inverters and power distribution cabinets, the PV panels convert light energy into electricity with flexible operating modes. The generated solar power can be self-consumed to support all internal equipment of the shelter, including supplementary lighting, automatic spraying, temperature control and cloud computing hosts. Excess electricity can be fed into the public grid to generate revenue, or stored in lithium battery energy storage systems for continuous stable power supply on cloudy days and nights with insufficient sunlight. This photovoltaic power supply solution features low carbon and zero pollution, complying with the energy-saving and emission-reduction trend of modern facility agriculture. It greatly reduces reliance on municipal power, significantly cuts daily electricity expenses during long-term operation, lowers overall operating costs and improves economic benefits of the project.
