Description

Technical Field

[0001] The invention relates to the technical field of photovoltaics, and in particular to a mounting structure for a photovoltaic array component and a photovoltaic array. Background Art

[0002] Since the output power of a single photovoltaic module is often insufficient to provide the actual power demand, they usually need to form a solar cell array to meet the design requirements. The orientation and inclination of the photovoltaic modules in the array are directly related to the power generation. In the prior art, photovoltaic modules are usually installed facing south through mounting brackets. A single module occupies a large area, which is not conducive to increasing the installation density of photovoltaic modules. At the same time, photovoltaic modules installed facing south have poor wind resistance, and it is necessary to install wind shields or more accessories for the photovoltaic modules, which increases the installation cost of the modules.

[0003] To solve the above problems, a Chinese invention patent with application number 201220551602.2 discloses a photovoltaic array with components installed in an east-west direction and a mounting bracket thereof. The photovoltaic array includes components and mounting brackets. The components are installed on the mounting brackets. The components in the array are installed in pairs through the mounting brackets. The two components installed in pairs are tilted to the east and west respectively. The mounting bracket includes a plurality of mounting bracket units, which are neatly arranged in the longitudinal and transverse directions. The mounting bracket units include a longitudinal beam and two tilted brackets installed on the longitudinal beam. The tilted bracket includes an inclined beam and a column. One end of the inclined beam is connected to the longitudinal beam, and the other end of the inclined beam is supported on the longitudinal beam through the column. Although the patent can solve the above problems, in the patent, the east-west photovoltaic components are supported by two separate brackets. This installation method increases the material cost and installation cost. Moreover, since the pressing blocks are installed on the short sides respectively, there are safety risks for the double-sided double-glass modules. In addition, in order to allow the back of the module to receive light and generate electricity, the module generally needs to be raised by more than 0.3 meters, and the distance between the two sides and the top needs to be increased to increase light transmittance. However, this installation method will make it difficult to ensure the uniformity of light on the back of the module. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a mounting structure for a photovoltaic array assembly.

[0005] The present invention provides a mounting structure for a photovoltaic array assembly, and its technical solution is as follows:

[0013] Wherein, a guide rail mounting member is further provided between the adapter and the top beam, and the adapter is mounted on the top beam through the guide rail mounting member.

[0014] Wherein, a connecting rod is further provided between the corner bracket and the supporting bracket, one end of the connecting rod is connected to the corner bracket, and the other end of the connecting rod is connected to the supporting bracket.

[0015] Among them, the angle γ that prevents the photovoltaic module from rotating satisfies the following relationship:

[0016] γ=β-α

At the same time, the bolt assembly installation method can effectively improve the roof utilization rate, increase the installation capacity of the system, and effectively save the time cost and labor cost of installation. In addition, the mounting structure provided by the present invention can realize the arrangement of component arrays, so that the sunlight can pass through the gap between the two arrays and the top gap to enter the roof on the back of the component, and use the diffuse reflection of the roofing material to make the back of the component receive light and generate electricity.
