Solar Panel Maintenance and Care

Although a well designed vehicle-mounted solar system requires minimal maintenance, it is highly recommended to perform an inspection and cleaning of the solar panels during the warranty period. This helps to ensure optimal system performance and reliability through a few simple steps.

Visual Inspection
Perform a visual inspection of the solar system on a monthly basis to identify if there are any visual defects or improper connections.

• Check for any sharp objects on the solar panel surface.
• Check for any signs of corrosion or burnt hotspots around the solar cell and backsheet area.
• Check that the solar panel is clear of any shading by any foreign material or unwanted obstacles. Just a small amount of shade on the solar panel surface can cause significant power output loss.
• If the solar panel has slight discoloration over a period of usage, this is considered normal for solar panels that use an anti-reflection coating laminate.

Cleaning Solar Panels

• The power output of a solar panel is proportional to the amount of sunlight that reaches the solar cells. Therefore, any build-up of dust or dirt on the surface of the solar panel will result in a loss of power. This is a trade-off between the maximizing the power output of the solar panel versus the cost and time to perform regular cleaning.
• Do not clean solar panels if there is broken plastic material or exposed wiring because this creates a risk for electric shock.
• Do not step or kneel on the solar panel during cleaning.
  • Check the solar panel periodically during seasons that the vehicle is in-use. If there is a build-up of dust or dirt on the surface of the solar panel, it is recommended to clean it.
  • Clean the solar panel in the early morning or early evening when the solar panel is cooler, especially in hot regions. This will reduce the risk for electrical and thermal shock.
  • Clean using a soft cloth together with clean water and mild detergent or soap.
  • Make sure there is no soap residue remaining after cleaning.
  • Avoid using water with high mineral content that may leave deposits on the solar panel surface.
  • Do not use abrasive materials to clean the solar panel.
  • Do not use chemicals to clean the solar panel.
  • Do not pressure wash the solar panel.
