Problems solved by technology

This installation structure will cause the inclination angle of the photovoltaic module 22 on the second roof structure 12 on the roof to be a negative angle.
In this case, the power generation capacity of the photovoltaic modules 22 in this part will be greatly reduced, resulting in a significant loss of power generation in the entire power generation project.

Embodiment Construction

[0018] Such as figure 2 As shown, a specific embodiment of the photovoltaic module installation structure of the light steel truss sloping roof of the present invention includes a first roof structure 11 with a positive inclination angle A and a second roof structure 12 with a negative inclination angle B. A first photovoltaic assembly 21 is disposed on the first roof structure 11 , and a second photovoltaic assembly 22 is disposed on the second roof structure 12 . In this embodiment, both the first roof structure 11 and the second roof structure 12 are light steel structures.

[0019] The special feature of the present invention is that a supporting frame 3 is arranged between the second roof structure 12 and the second photovoltaic module 22, and the supporting frame 3 is wedge-shaped (or trapezoidal).

[0020] Further, the wedge angle C of the wedge shape is greater than or equal to the negative tilt angle B, so that the second photovoltaic module 22 is in a horizontal po...

Abstract

The invention discloses a photovoltaic module arrangement structure for a sloping roof of a lightweight steel roof truss, which comprises a first roof structure with a positive slant angle, and a second roof structure with a negative slant angle. First photovoltaic modules are disposed on the first roof structure, and second photovoltaic modules are disposed on the second roof structure. A support frame in a wedged shape is disposed between the second roof structure and the second photovoltaic components. The photovoltaic components on the shadow side of the photovoltaic module arrangement structure are substantially horizontal by the aid of the wedged support frame. Using the photovoltaic module arrangement structure can reduce solar radiation loss and improve power generating efficiency.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a photovoltaic module installation structure of a light steel roof truss slope roof. Background technique [0002] In photovoltaic power generation projects, according to the principle of photovoltaic power generation, the inclination angle of photovoltaic modules affects the power generation of the entire power generation project to a large extent. The aforementioned inclination angle refers to the angle between the plane of the photovoltaic cell (also called solar cell) square array and the horizontal ground. According to the analysis and calculation of multiple parameters such as the latitude of the project location, an optimal inclination angle that maximizes the power generation of the photovoltaic cell array in a one-year time period can be theoretically obtained. However, in actual construction, subject to various factors such as the construction env...
