Photovoltaic device

Abstract

The invention discloses a photovoltaic device. The photovoltaic device comprises photovoltaic components which are obliquely arranged on a base from bottom to top, wherein the rear sides of the photovoltaic components are provided with deflectors which are obliquely arranged on the base from bottom to top in the direction from rear to front. According to the invention, the deflectors are designed to reduce the shape coefficient and pulling force when wind load acts; due to design of spoilers, the air flow speed is changed, downward pressure is generated, and the spoilers can play a role in increasing the weight and reduce the pulling force and the deviating force under the action of the wind load; due to design of the base consisting of guide rails and supporting columns thereon, the installation of the supported photovoltaic components, the deflectors and the spoilers is convenient and stable, and an arrayed whole body can be conveniently formed, so that photovoltaic device is firmer; and due to design of a clamping structure consisting of front supporting columns, rear supporting columns and pressing strips, the longitudinal gap is automatically made up in the clamping process of the photovoltaic components, and the components can be prevented from sliding out.

Description

technical field [0001] The invention relates to the field of solar photovoltaics, in particular to a photovoltaic device. Background technique [0002] Building energy conservation and photovoltaic power generation are the key development directions of the modern construction industry. Therefore, BIPV is a new technology with great potential and significant value. The photovoltaic power generation device on the roof of the building mainly includes battery components composed of solar cells and carriers. The battery components are installed on the roof facing the sun, and the solar cell components convert light energy into electrical energy, and collect the electrical energy and input it into the grid. There are many technical solutions, which belong to the relatively mature technology, and the general structure of the photovoltaic power generation device is as follows: figure 1 Shown, comprise column 31, beam 32 and ceiling 33, analysis bar 34 and grid 35 are installed on ...

AI Technical Summary

Problems solved by technology

[0003] In addition, ordinary photovoltaic devices installed with battery modules need to be able to withstand wind loads for 50 years, so prefabricated cement foundations are required, which will damage the original roof; cement foundations and roof waterproofing will increase the cost of photovoltaic systems ; In addition, the processing error and assembly error of the existing bracket will make it difficult to install the bracket

In addition, ordinary photovoltaic installations have a large counterweight and require high support capacity on the roof.
