Before you start using your soapy mixture, rinse the panels with water to wash away any initial dirt or debris. Afterwards, dip your sponge into your bucket of soapy water and gently scrub the panels. Try not to use too much force when cleaning, and don’t add any harsh chemicals to your washing solution.
Rinse off the soap after you’re satisfied with your efforts, making sure there is no residue or suds left. You can then use a soft cloth to wipe the remaining water.
Your solar panel cleaning session is also the perfect time to inspect them for signs of damage to prevent any existing issues from worsening over time.

Why Cleaning Your Solar Panels is Important
Clean panels can produce more energy, maximising their usage. When they’re covered in debris, bird droppings and dust, this buildup blocks the sun, which reduces their efficiency. Regular cleaning ensures you’re getting the most energy out of your panels so they’re functional and cost-effective, giving you a higher return on your investment.
Keeping them clean helps to prevent long-term damage, which can be caused by excessive debris. Well-functioning solar panels can also in some cases add value on your property so it’s worth keeping them in good condition.
Clean Solar Panels Look Better
Imagine your solar panels are similar to your car. Would you want to drive around with your car covered in dust, dirt and bird droppings? The answer is likely no! So, for the same reason, solar panels look better when they’re clean and free of noticeable stains.
Eco-Friendly Effects
Clean, well-maintained solar panels are more efficient, eco-friendly and contribute to renewable energy production as well as to your property value.
Ongoing Maintenance
In some cases, dirty solar panels can negatively affect your warranty coverage, many companies recommend regular cleaning so it’s best to double check your paperwork and follow any guidance given.
Investing in solar panels can be a step towards a more environmentally friendly home. They can save you money in the long run and add value to your home, which are some of the main reasons it’s worth keeping them clean, so they operate at their best.
