Solar Panel Inner Clamp
The solar panel inner clamp (also known as the mid-clamp or inner clamp) is a key connecting component in a photovoltaic (PV) mounting system used to secure the frames of adjacent solar modules. Its core function is to work in conjunction with the guide rail system during PV module installation to stably press two adjacent modules together and maintain a precise distance, thereby ensuring the stability and long-term reliable operation of the entire array structure. In modern PV power plant construction, the continuous increase in module power density and the expanding system span place higher demands on the mechanical properties, corrosion resistance, and long-term stability of mounting structural components. As a crucial node connecting modules and the mounting system, the mid-clamp not only affects installation efficiency but also directly relates to the structural safety and operational lifespan of the power plant.

Product Introduction
The Solar Panel Inner Clamp (medium-voltage Inner Clamp) is primarily used to secure the intermediate connection points between photovoltaic (PV) modules, forming a complete modular mounting system in conjunction with the End Clamp. Standard applications include:
Ground-mounted centralized PV power plants
Commercial and industrial rooftop PV systems
Agricultural-PV hybrid PV brackets
Distributed generation systems
Building Integrated Photovoltaic (BIPV) structures
Solar carports and PV support structures
Core functions include:
Securing the frames of adjacent modules
Maintaining standard installation spacing between modules
Distributing wind and snow loads
Improving the overall array structure stability
Enhancing installation efficiency and standardization
Design Advantages
Ergonomic Optimization
Rounded edges on the Aluminum Solar Mounting Mid Clamps prevent scratches to modules or operators during installation; pre-set positioning slots ensure more precise installation and reduce on-site adjustment time.
Thermal Stress Adaptation Design
Fully considering material expansion due to diurnal temperature variations, elastic buffer structures absorb deformation stress, preventing loosening or fatigue fracture during long-term use.
Aesthetics and Functionality Combined
The low-profile design does not affect optimized module spacing and ventilation, while the overall appearance is simple and unified, enhancing the overall visual appeal of the power station, suitable for commercial and industrial rooftop Solar Panel Mounting Middle Clamps, where aesthetics are important.
Application Advantages: Universal Applicability Across Terrains and Climates
| Commercial and Industrial Steel Roofs and Ground Arrays | On commercial and industrial roofs, wind uplift resistance is crucial. Our medium-voltage systems, coupled with specialized rails, provide several times the pull-out resistance required by conventional methods, Solar Panel Mounting Mid Aluminum Clamp, ensuring the safety of PV arrays on factory roofs in typhoon-prone areas. In-ground arrays, with their ability to adapt to structural displacement caused by minor terrain subsidence avoids rigid stress on the modules. |
| Aquaculture-Solar Hybridization and Floating PV (Floating Power Stations) | The water surface environment has extremely high humidity and is rich in corrosive ions. Our reinforced anodized medium-voltage systems, and even optional stainless steel versions, can withstand long-term immersion or exposure to high-humidity salt spray environments without electrochemical corrosion, providing absolute security for the 25-year lifespan of floating PV systems. |
| Agricultural-Solar Hybridization and High Snow Load in High-Latitude Regions | In northern high-latitude regions, heavy winter snowfalls can lead to enormous downward loads. Our medium-pressure high-strength web and wide contact surface can effectively distribute snow load to the guide rail system, prevent the component frame from twisting and deforming due to excessive local pressure, and ensure the system's safety in frigid regions. |
Material advantages
High-quality 6005-T5 aluminum alloy or 304 stainless steel is selected as the main material. After anodizing or a special surface treatment process, the Solar PV middle clamp Panel Mid fixing has excellent corrosion resistance. The aluminum alloy material is lightweight and high-strength, which effectively reduces the overall weight of the bracket system and reduces the burden of transportation and installation. The stainless steel version shows stronger weather resistance in high salt spray, strong acid and alkali environments, and is suitable for special application scenarios such as coastal areas and chemical industry parks.
The surface of the material adopts an environmentally friendly anodized film layer with uniform thickness and strong adhesion. It is not only beautiful and durable, but also effectively resists ultraviolet aging and sand and dust wear. Compared with ordinary materials, the material of this Solar PV Module Middle Clamp shows a longer service life in weather resistance tests, helping engineering projects achieve low-maintenance operation for more than 25 years.
