Have you ever encountered issues such as the breakage of bolts, quick clamps, or mid/end clamps during the installation of solar PV systems? Today, we will analyze the causes of these problems and explore effective solutions.

Causes of Breakage in Solar Mounting Accessories

Material Quality Issues

Substandard Material: Insufficient material strength can fail to withstand tensile, compressive, or environmental loads during installation and long-term operation. For instance, bolts made of low-strength steel are prone to breakage.

Improper Heat Treatment: Inadequate heat treatment or cooling during manufacturing can result in insufficient hardness and toughness, increasing the risk of breakage.

Improper Installation

Over-Tightening: Excessive torque during installation may cause undue stress on components, especially for quick clamps and mid/end clamps that require precise fastening. It is recommended to strictly follow torque guidelines (contact us for details).

Uneven Force Application: Uneven tightening of bolts may lead to stress concentration, increasing the likelihood of breakage.

Misalignment: Improper alignment during installation may create localized stress, resulting in component failure.

Environmental Factors

Temperature Fluctuations: Extreme temperature changes can cause metal expansion or contraction. Without adequate design considerations, this may lead to material fatigue and eventual breakage.

Wind Loads: Prolonged wind exposure can cause repeated stress on components, leading to cracks and eventual breakage.

Corrosion: Exposure to humid or saline environments accelerates metal corrosion, weakening the strength of components.

Design Defects

Inadequate Design: Insufficient strength, size, or shape in the design of components like bolts and clamps may result in insufficient load capacity and eventual failure.

Stress Concentration: Stress concentration points in design are prone to becoming the origin of cracks. Reinforcements, such as thicker designs in key areas, can effectively mitigate this issue.

Transportation or Storage Damage

Damage Before Installation: Micro-cracks caused by impacts or friction during transport or handling may worsen after installation.

Improper Storage: Storing components in humid environments can cause corrosion and reduce their lifespan.

Overloading

Exceeding Load Capacity: If the system design does not adequately account for the actual weight of solar panels or extreme weather conditions, components may fail under excessive loads.

Solutions

Ensure High-Quality Materials: Use premium materials subjected to rigorous heat and surface treatments.

Standardized Installation: Follow installation guidelines strictly, including proper torque application and alignment.

Scientific Design: Consider load distribution, environmental factors, and stress points during the design phase to ensure strength and durability.

Regular Inspection and Maintenance: Conduct routine checks, especially after extreme weather, to identify and replace damaged components promptly.
