Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of lap joint type photovoltaic module, especially to a lap joint type photovoltaic module connecting structure. BACKGROUND

[0002] With the growing demand for clean energy worldwide, the photovoltaic industry, as an important part of the renewable energy field, has developed rapidly in recent years. Solar photovoltaic power generation has the advantages of being clean, renewable and widely distributed, and is considered one of the important solutions to energy crisis and environmental pollution problems. Under the dual driving of policy support and market demand, the construction scale of photovoltaic power stations is continuously expanding, from large-scale ground centralized photovoltaic power stations to distributed photovoltaic power generation systems, such as industrial and commercial roof and residential roof, which have widely applied photovoltaic modules. This puts forward higher requirements for the connection structure of photovoltaic modules, not only to ensure reliable connection between modules, but also to meet the installation, maintenance and performance requirements in different application scenarios.

[0003] The current market lap joint type photovoltaic module is mainly composed of physical connection components and electrical connection components. The traditional lap joint type photovoltaic module connecting structure is prone to looseness due to external environmental factors during long-term use. Since photovoltaic modules are usually installed outdoors, they will face various weather conditions such as strong winds, heavy rains and earthquakes. The traditional connecting structure may not have fully considered these external force factors in design, resulting in insufficient connection strength at the lap joint part. The contact area of the narrow edge lap joint method is small, and under the action of wind force, the modules are prone to relative displacement, thereby affecting the stability and safety of the entire photovoltaic system. Moreover, ordinary metal connecting pieces are prone to rust and corrosion under long-term sun and rain, reducing the reliability of the connection. At the same time, the installation process of the traditional lap joint type photovoltaic module connecting structure is relatively complex, requiring professional installers and tools, and the installation steps are tedious and time-consuming, which not only increases the installation cost but also may affect the construction progress of the project. In terms of maintenance, since the connecting structure is not convenient to disassemble and replace, when a component fails, maintenance personnel need to spend a lot of time and effort to repair and replace it, and in the disassembly process, other components may be damaged. At the same time, the traditional connecting structure lacks effective monitoring means, making it difficult to real-time understand the connection state and electrical performance of the components, which is not conducive to timely discovering and solving potential problems.
