FAQ About Solar Fasteners
Solar fasteners are specifically designed to withstand outdoor conditions like UV exposure, temperature fluctuations, and high corrosion from environmental factors. They also need to maintain tight torque over long periods to prevent loosening in racking systems or solar panels.
Solar fasteners are used in a variety of solar applications, including ground-mount racking systems, rooftop solar installations, solar trackers, and energy-storage systems. They are also used in cable management and grounding solutions to ensure the system stays secure and electrically bonded.
Hot-dip galvanizing is a process where fasteners are coated in a thick layer of zinc to provide superior corrosion protection. This is particularly important in solar installations that are exposed to the elements, including rain, wind, and salt air, to ensure the fasteners last for many years without rusting or weakening.
The lifespan of hot-dip galvanizing depends on factors like environmental conditions (e.g., exposure to salt air or industrial environments) and the thickness of the zinc coating. In typical solar applications, the galvanized surface can last 20-50 years, significantly outlasting many other coating methods and ensuring long-term performance of the solar system.
