Method and device used for installing photovoltaic array on east-and-west-facing slopes

Abstract

The invention belongs to the technical field of photovoltaic application, and particularly discloses a method used for installing a photovoltaic array on an east-facing slope or on a west-facing slope. The method comprises the steps of (1) setting the oblique plane of the slope as A and determining the slope angle Alpha; (2) determining the optimal installation tilt angle Theta of the photovoltaic array in the area, determining the installation azimuth angle Zeta of the photovoltaic array, setting the oblique plane of the photovoltaic array as B and enabling the oblique plane B of the photovoltaic array to intersect with the oblique plane A of the slope on a straight line c; (3) arranging the photovoltaic array in the direction parallel to the straight line c, enabling the included angle between the straight line c where the oblique plane A of the slope intersects with the oblique plane B of the photovoltaic array and the bottom edge straight line d of the slope to be Beta, and enabling the included angle between the oblique plane B of the photovoltaic array and the oblique plane A of the slope to be Theta'. According to the method, the photovoltaic array can be installed on the east-facing slope or on the west-facing slope in the north-south direction by means of a front support and a rear support which are uniform in length specification, a support system can be manufactured conveniently, materials can be saved, installation of the photovoltaic array can be achieved more easily, construction accuracy, efficiency and quality are improved, influence caused by shading of shadows between a front row and a back row of the photovoltaic array is reduced, and then the land utilization rate and electric energy production in a power station are improved.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic applications, and specifically discloses a method and a device for installing a photovoltaic array on an east-facing or west-facing slope. Background technique [0002] The main function of the photovoltaic array is to convert the solar radiation received by the photovoltaic components into DC power. Therefore, the main purpose of considering the layout of the photovoltaic array is to ensure that the photovoltaic components of the photovoltaic array can receive as much and reliable solar radiation as possible. For a fixed-installed photovoltaic array, in order to allow the photovoltaic array to receive as much solar radiation as possible, in the northern hemisphere, the photovoltaic array is usually installed facing the south, and in the southern hemisphere, it is installed facing the north. [0003] Install photovoltaic arrays on east-west slopes. Since they are facing due south or due north...

AI Technical Summary

Problems solved by technology

In order to match the terrain characteristics of the east-west slope of the installation site, the installation of photovoltaic arrays in the east-west direction will inevitably require photovoltaic array supports with inconsistent length specifications. It is not conducive to the production and processing of photovoltaic array brackets, and it is easy to cause waste of bracket materials, which is undoubtedly not conducive to the control of installation costs of photovoltaic arrays

In addition, because the specifications of the photovoltaic array support are not uniform, it is easy to install the wrong support during the construction process, resulting in defects such as a single photovoltaic array or inconsistent installation angles between photovoltaic arrays and photovoltaic arrays, which is not conducive to the improvement of construction accuracy and quality. , the speed of construction will be greatly reduced
