Solar panels are a fantastic form of renewable energy and they will save you thousands of dollars in electricity costs. However, to keep them operating at peak efficiency, regular maintenance is essential. Over time, dust, dirt, bird droppings, and other debris can accumulate on the surface, reducing their ability to absorb sunlight. While cleaning them may seem straightforward, using the wrong techniques can lead to irreparable damage. Here we’ll take a look at the safest and most effective ways to clean solar panels without causing harm, and why professional solar panel cleaning might be your best bet for long-term performance.

Why Clean Solar Panels?

Solar panels rely on sunlight to generate electricity. When the surface is dirty, it can:

  • Reduce energy efficiency and power output
  • Cause long-term wear and tear
  • Lead to potential overheating in extreme cases
  • Shorten the lifespan of the panels

By keeping your panels clean, you ensure they operate efficiently and maximise your return on investment.

Safe Methods for Cleaning Solar Panels

Before you begin any cleaning, consult the manufacturer’s recommendations. Some panels have specific cleaning requirements, and using the wrong method or solution could void the warranty!

Choose the Right Time to Clean – The best time to clean solar panels is early in the morning or late in the evening when they are cool. Cleaning hot panels can cause rapid temperature changes, leading to cracks or damage.

Use Soft, Non-Abrasive Materials – Never use abrasive scrubbers or harsh chemicals that can scratch the surface. Instead use a soft sponge or microfibre cloth and a squeegee for drying.

Water Only or Mild Detergent – In most cases, plain water is sufficient for cleaning solar panels. If there are stubborn stains or built-up bird droppings, you can use a mild detergent mixed with water just make sure that you rinse thoroughly to remove any soap residue.

Avoid Pressure Washers – High-pressure washers can crack solar panels, damage their frames, and compromise electrical connections. A garden hose with gentle water pressure is the best option.

Clean on a Cloudy Day – Cleaning under direct sunlight can cause water to evaporate quickly, leaving streaks or mineral deposits. A cloudy day or a cool part of the day ensures a streak-free finish.
