Routine Cleaning and Inspection

So now onto the question: What maintenance is required for solar?

Routine cleaning and inspection form the cornerstone of solar panel maintenance. It is typically advised that you perform solar panel cleaning between two and four times per year.

Solar panels are exposed to the elements, and over time, they naturally accumulate dirt, dust, pollen, leaves, bird droppings, and other debris. This accumulation acts as a barrier, obstructing the sunlight from reaching the solar cells and reducing the panels’ energy-harnessing capabilities. As a result, routine cleaning is essential to remove these obstructions, allowing your panels to capture as much sunlight as possible.

Cleaning solar panels is a straightforward process, but it must be done with care to avoid damaging the panels or compromising safety. To safely clean your solar panels, follow these step-by-step guidelines:

  • Safety First: Before starting, turn off the solar panel system to avoid electrical shock. If your solar panels are on the roof, you can use proper fall protection equipment and take necessary precautions.
  • Gather Supplies: Gather the necessary cleaning supplies, including a soft brush or sponge, a bucket of soapy water (mild dish soap is suitable), a hose or deionized water, and a soft cloth for drying.
  • Gentle Cleaning: Dip the brush or sponge into the soapy water and gently scrub the surface of the panels. Avoid using abrasive materials or harsh chemicals that may scratch or damage the panels.
  • Rinse Thoroughly: Rinse the panels thoroughly with clean water to remove all soap residue. You can use a hose or deionized water for this purpose.
  • Dry Carefully: Use a soft, lint-free cloth to dry the panels gently. Avoid using abrasive materials that may scratch the surface.

Regular inspections complement cleaning by helping you identify and address potential issues early on. During inspections, check for any visible damage, loose connections, or signs of wear and tear. Inspect the wiring, junction boxes, and mounting hardware.
