Safety Comes First
It might seem like an obvious one, but check the weather is clear with no signs of rain before you start cleaning your solar panels. Rain can make the process difficult and potentially dangerous if you're on the roof, as well as leave streaks on any freshly cleaned panels. Aim to clean on a cloudy day, as too much sun can make the panels hot.
If the forecast is all clear, then first turn off the solar panels by properly following the manufactures instructions. Wear proper safety gear like gloves, and if you're climbing up a ladder to access your solar panels or cleaning them on the roof, then ensure you're wearing non-slip comfortable shoes. In this situation, it's also wise to have somebody keeping an eye on you.
Select the Right Cleaning Products
When it comes to solar panel cleaning, avoid using rough brushes and hardwearing squeegees as they could cause damage; instead, pick a soft sponge or gentle brush that can effectively wipe them clean without leaving any scratches. For the cleaning solution, select a mild soap and mix it with water. To avoid mineral build up and water stains, use distilled water, and don't use a strong hose as it could cause issues with the seal.
Whatever you do, don't stand on your solar panels as this can cause damage, so for hard-to-reach places, select a soft squeegee or sponge with a long attachment.

How to Clean Solar Panels
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.

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
