Solar double-sided photovoltaic power generation internal shading system for greenhouse

Abstract

The invention discloses a solar double-sided photovoltaic power generation internal shading system for a greenhouse. rotating shafts (3) are mounted on side frames of double-sided photovoltaic modules (1) and are fixed on a support (2); the support (2) consists of mounting channels of gears (7) and chains (8), and a direct-current wire laying channel (9); the end parts of the rotating shafts (3) are provided with the gears (7), the chains (8) in the support (2) are controlled to move through a first motor (4 (1)) or a second motor (4 (2)), and the gears (7) rotate to open or close the double-sided photovoltaic modules (1) to achieve shading; and when solar radiation exists and the shading requirement is met, electric energy generated by the double-sided photovoltaic modules (1) is stored in a storage battery pack (12) through an inversion control all-in-one machine (11), the storage battery pack (12) is connected with a direct-current load (13), and the inversion control all-in-one machine (11) can achieve alternating-current output and directly input into an alternating-current load (14).

Description

technical field [0001] The invention relates to a greenhouse technology, in particular to a solar double-sided photovoltaic power generation inner shading technology for a greenhouse. Background technique [0002] The excessive greenhouse effect caused by solar radiation in summer makes the temperature and humidity in the greenhouse too high, which is not suitable for crop growth, and the problem of pests and diseases is highlighted. Therefore, the application of shading system to the greenhouse is a powerful measure to solve the overheating of the greenhouse, which can effectively regulate the suitable environment for crop growth and realize the efficient and high-quality production of the solar greenhouse. [0003] The traditional greenhouse shading method uses sunshade nets, which can cool down the greenhouse to a certain extent, but cannot effectively use solar energy. Double-sided photovoltaic modules can realize photovoltaic power generation on the front and back side...
