Module Cleaning and Inspection

  • Module Cleaning Precautions

    • Cleaning tool: Kärcher high-pressure washer.
    • Cleaning liquid: Do not use other liquids except water.
    • Climatic conditions: cleaning is prohibited under climatic conditions such as wind force > level 4, heavy rain, lightning, and high temperature.
    • Number of workers: 2-5 people. It depends on the area of the power plant.
    • Cleaning standard: The solar module will be  visually inspected with no stains and no obvious difference in brightness.

  • Safety Facility Inspection

    • Locking point of the securing female lock inspection
    • Safety trail inspection
    • Ladder inspection
    • Protection cage inspection

  • Module Inspection and Maintenance Items

    • The glass broken, the backboard burnt, or the color changes obviously.
    • Check whether there is no short circuit in the edges of the component or any circuits.
    • Due to deformation, twist, crack or burn, the terminal can not be connected properly.
    • Visually inspect the hollow glass of the module for moisture condensation or water seepage, which affects the light radiation absorption of the solar panel.
    • Visually inspect hollow glass for the explosion, including the thermal explosion of glass and self-explosion of tempered glass.
    • The brackets or rear bolts used to fix the solar array shall not be loose.
    • The solar array which is installed on a prefabricated base, the base should be placed stably and neatly, and its position should not be moved.
    • The main stress components, connecting components and connecting bolts of the solar array shall not be damaged or loosened, without gaps in the weld seam.
    • The anti-rust coating of metallic materials shall be complete, without peeling or rust.
    • The entire solar array shall not be deformed, dislocated or loosened.
    • Inspect the cement base for cracks.
    • Earthing resistance testing.
