Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic assembly installation, and in particular relates to a mountain photovoltaic assembly rock anchor foundation structure and a construction method thereof. Background Art

[0002] Photovoltaic modules generally refer to solar cell modules. Since the output voltage of single-chip solar cells is low, and the electrodes of unpackaged cells are easy to fall off due to environmental influences, a certain number of single-chip cells must be sealed into solar cell modules in series and parallel to avoid corrosion of battery electrodes and interconnects. In addition, packaging also avoids battery fragmentation and facilitates outdoor installation. The quality of packaging determines the service life and reliability of solar cell modules. Solar cell modules are composed of high-efficiency crystalline silicon solar cells, ultra-white cloth-textured tempered glass, EVA, transparent TPT backplane and aluminum alloy frame. It has the characteristics of long service life and strong mechanical resistance to external pressure. The structural forms of conventional solar cell modules are as follows: glass shell structure, bottom box module, flat panel module, and full-glue sealed module without cover. Since the single solar cell itself is easy to break and corrode, if it is directly exposed to the atmosphere, the photoelectric conversion efficiency will decrease due to the influence of moisture, dust, acid rain, etc., resulting in damage and failure. Therefore, solar cells must generally be packaged into flat-plate structures by glue sealing, lamination, etc. before being put into use. Solar cell modules require: a certain nominal operating current output power; long service life, so the materials, components and structures used in the modules are required to be consistent in service life to avoid failure of the entire module due to damage in one place; sufficient mechanical strength to withstand collisions, vibrations and other stresses during transportation, installation and use; small electrical performance loss caused by the combination, and low combination cost.

[0003] In the prior art, in mountainous environments, due to the irregular ground and a certain inclination, photovoltaic modules are inconvenient to install. The installation structure is relatively simple, and the fixing effect of the installation is poor. When the photovoltaic modules are used for a long time, they are prone to fall off and have poor stability. Summary of the invention
