But there are a couple of things to keep in mind. Hiring a solar specialist that specializes in cleaning is usually a good idea.

Going atop your roof might be dangerous, especially if it’s high and sloping because an accident could occur.

Furthermore, frigid locations with temperatures below freezing may cause the water you hose onto your panels to freeze. To lessen the probability of ice developing on your panels, use very warm water or wait until the temperature rises.

Of course, a fall safety system should always be used.

The Occupational Safety and Health Administration (OSHA) has several fall protection regulations. These regulations apply to service personnel that installs or maintain solar panels, including cleaning them. They are, nevertheless, equally important for non-service professions to consider.

OSHA mandates a conventional guardrail if the fall danger is 4 feet or higher. Alternatively, if your solar panels are at least 6 feet above the ground, OSHA mandates the following fall safety methods:

  • System of guardrails
  • System of safety nets
  • Personal fall protection systems

Step-By-Step Guide On How To Clean Solar Panels Effectively


Learning how to clean a solar panel properly is critical if you want your system to perform optimally. Furthermore, regular cleaning prevents unwanted damage to your panels and preserves them in good shape for years.

The most crucial measures to take when cleaning your panels are outlined below.

Begin by reviewing the manufacturer’s instructions. They detail the steps on how to clean your specific solar panel brand. Following those guidelines can also help you avoid causing unneeded harm to the panels.

2. Get Rid Of Loose Dirt And Debris

Also, before cleaning your solar panel system, make sure you turn it off. The manufacturer’s instructions should explain how to turn your system off.

After that, clean up any loose dirt and debris from the panels. Dirt and debris can quickly build and reduce the efficiency with which your panels generate energy. Before cleaning the panels, use a leaf blower to remove the majority of the accumulation.

Furthermore, whenever and if you get on top of your roof, make sure to protect yourself. Wearing appropriate work attire, non-slip footwear, and, most importantly, employing a fall protection system are all part of this.

This is a simple and necessary precautionary measure to avert major mishaps.

Next, spray the panels with water to eliminate any remaining dirt, dust, or debris.

However, high-pressure water sprayers or water jets should not be used for this stage. The intense water spray has the potential to harm the panels.

The power of a high-pressure water sprayer might potentially cause you to lose your balance. Make use of a low-pressure hose or buckets of water.

When learning how to clean roof solar panels, climbing on the roof may allow you to clean them more thoroughly. However, be cautious because water might make the roof slippery. When cleaning roof panels, wear protective equipment.

4. Squeegee

Use a squeegee to remove any surplus water after cleaning the panels with water. Because it avoids mineral buildup, this procedure is especially crucial if you have hard water.

Use a squeegee with an extension handle if you have one. This allows you to remove water from difficult-to-reach regions.

5. Avoid The Use Of Abrasive Products

Finally, avoid using abrasive materials. Harsh detergents or rough sponges can harm your panels and reduce their effectiveness. Some detergents can also destroy your panels.

To maintain solar panels effectively, clean them using just water, gentle sponges, and soft cloths.
