Core Technical Features

The core technology of the solar panel mounting hardware focuses on the adaptability to photovoltaic scenarios, structural stability, and weather resistance, meeting the requirements of outdoor complex environments (high temperatures, heavy rain, strong winds, ultraviolet rays). The specific features are as follows:

• Wind and snow-resistant structural design: Optimizing component thickness and connection methods to enhance load-bearing capacity, capable of withstanding strong winds (8-12 levels) and snow pressure in different regions, preventing solar panels from loosening or falling off, and ensuring the long-term stable operation of the photovoltaic system.

• Weather-resistant and corrosion-resistant process: Using high-adaptation materials and surface treatment to resist outdoor ultraviolet rays, humidity, acids, and alkalis, avoiding rusting and aging of components, and adapting to different climate regions (coastal, highlands, rainy areas).

• Lightweight and precise adaptation: Balancing strength and lightweight, reducing the load on the support, while strictly controlling dimensional tolerances, precisely adapting to different specifications of solar panels (monocrystalline silicon, polycrystalline silicon), facilitating installation and improving construction efficiency.

• Scratch-resistant and insulation protection: The contact parts with the solar panel adopt anti-scuffing design to avoid scratching the panel; some components come with insulation coatings to prevent leakage and ensure the electrical safety of the photovoltaic system.
