Panel structure design method for double-sided solar cell tracking support

Abstract

The invention discloses a design method of a double-sided solar battery bracket panel which is applied to a tracking bracket and is added with reflector structures. Based on the power generation performance of front and back sides of a double-sided solar battery and the optical principle, the invention provides a design method of a panel structure of a double-sided solar battery tracking bracket.The method comprises the steps of (1) analyzing a general structure of a designed bracket panel and local latitude and longitude, sunshine and climate conditions, (2) determining the size data of thedouble-sided battery and the distance between bracket panel frames, and designing initial sizes and inclination angles of two reflectors at left and right sides of the double-sided solar battery, and(3) designing certain size margins for the two reflectors with the consideration of the change of the angle between direct sunlight and the double-sided battery to improve the amount of radiation received by the battery, and finally determining the size data of the whole bracket panel. According to the method, the overall structure of the bracket panel can be flexibly designed according to a localenvironment, the size of the double-sided battery and the like, and the amount of radiation received by the double-sided battery can be significantly increased.

Description

technical field [0001] The invention relates to the technical field of panel structure design of a solar tracking support, in particular to a method for designing a panel structure of a double-sided solar cell support with a reflector structure. Background technique [0002] Since both sides of the double-sided solar cell can generate electricity, and the power generation performance of the reverse side is only slightly weaker than that of the front side, the application of double-sided solar cells is becoming more and more extensive. However, generally double-sided batteries are mostly used in fixed brackets, or placed horizontally, or placed at a certain angle, or placed vertically. The double-sided battery placed horizontally or at a certain inclination angle cannot fully utilize the characteristics of power generation on both sides of the double-sided battery.

Problems solved by technology

Bifacial batteries placed horizontally or at a certain inclination angle cannot fully utilize the characteristics of power generation on both sides of the front and back. Although bifacial batteries placed vertically make effective use of the power generation characteristics of the front and back sides of the bifacial battery, they abandon Radiant energy at noon when the sun is at its strongest

[0003] There are also some installation methods that try to install a flat reflector or a curved reflector under the double-sided battery to increase the radiation on the reverse side of the double-sided battery. However, since the double-sided battery is fixed, it will inevitably lose a lot of solar radiation. And Due to the change of the angle of the sun's rays, the radiation gain provided by the fixed reflector to the reverse side of the double-sided cell through reflection is also limited.
