Abstract

The invention discloses a sunlight greenhouse solar photovoltaic power generation utilization device and method. A plurality of pieces of solar photovoltaic power generation glass or films parallel to the vertical surface of a back vertical wall of a greenhouse realize the arrangement at intervals through positioning clamps and are fixedly connected with a fixing framework, the front and back span of the greenhouse, the height of the vertical surface of the back vertical wall of the greenhouse, the left and right house total width of the greenhouse, the average heat absorption factor of the back vertical wall and the distance from the solar photovoltaic power generation glass or films to the vertical surface of the back vertical wall of the greenhouse are determined; then, the solar photovoltaic power generation glass or films are selected, and the distance from the solar photovoltaic power generation glass or films to the left side wall and the right side wall of the greenhouse and the height from the solar photovoltaic power generation glass or films to the ground of the greenhouse are determined; and finally, the installation number of the solar photovoltaic power generation glass or films and the space between every two pieces of solar photovoltaic power generation glass or every two solar photovoltaic power generation films are determined according to a formula. Partial solar energy irradiating to the vertical surface of the back vertical wall of the sunlight greenhouse is converted into electric energy, the solar utilization rate in unit area of the greenhouse is improved, and planted crops can be ensured to normally obtain illumination.

Description

technical field

[0001] The invention relates to the technical field of solar energy utilization in greenhouses, in particular to a method and device for utilizing solar photovoltaic power generation in solar greenhouses. Background technique

[0002] At present, in the northern regions of my country, especially in areas between 35° and 45° north latitude, solar greenhouses are the most important agricultural production facilities. As a commonly used greenhouse structure in northern my country, solar greenhouse has advantages but also has certain defects in the regulation of the environment in the greenhouse and the utilization of solar energy. A big difference between the existing solar greenhouse structure in our country and the ordinary single arched greenhouse is that the solar greenhouse has a rear wall specially designed to store heat. However, in the daily production process of the greenhouse, especially in sunny conditions during the day, due to the limitation of the...
