The temperature and humidity can be artificially adjusted and are widely used in the out-of-season cultivation of vegetables. Most of the existing agricultural greenhouses are equipped with environmental conditioning equipment. When the external environment changes, the environmental conditioning equipment is needed to regulate the environment of the solar greenhouse so that the solar greenhouse can reach a state more suitable for production. The power supply of the environmental conditioning equipment is achieved by substations. Strong electricity is transmitted to the solar greenhouse through the substation to power the environmental conditioning equipment, resulting in higher usage costs.

[0003] The prior art CN117348649A discloses a greenhouse control system based on solar energy, including solar photovoltaic components, a control host, a roller shutter device, a fan component, a film roller, a valve component and a sensor component. After the solar energy is converted into electrical energy, it is supplied to the greenhouse control system, thereby eliminating the need to move strong electricity into the solar greenhouse to power various devices, and the construction cost of the solution is relatively low.

[0004] However, the solar photovoltaic components of the greenhouse control system only provide power for the greenhouse control system, and do not control the temperature of the greenhouse, resulting in the greenhouse temperature still being controlled by hot water heating, and the hot water required for heating consumes a large amount of non-renewable energy such as coal and fuel oil. Summary of the invention
