What maintenance is necessary for flexible solar panels on boats?

Cleaning and Inspection

Clean your flexible solar panels at least quarterly by gently hosing them down with a low-pressure spray nozzle, using a soft-bristled brush to remove dirt and debris. For more thorough cleaning, mix a solution of 1 part white vinegar to 2 parts water and apply it to the panels using a soft cloth or sponge. Avoid using harsh chemicals, abrasive materials, or high-pressure washes that can damage the panels.

Water Ingress and Drainage

Check the waterproof sealants around the edges of your flexible solar panels and the electrical connections for signs of damage or wear. Inspect the drain channels and ensure they are clear of debris to prevent water from accumulating on the panels. Apply silicone sealant to any gaps or cracks to prevent water ingress.

Electrical and Mechanical Checks

Verify that all electrical connections are secure and not damaged. Check the voltage and current output of your solar panels using a multimeter to ensure they are functioning within the manufacturer’s specifications. Periodically inspect the mechanical mounting system to ensure it remains secure and does not put undue stress on the panels, which can cause damage or reduce their lifespan.
