Solar panels are the perfect household item that converts sunlight into electrical energy to power up your home. It helps you save on electricity bills while having a renewable and sustainable energy source that doesn’t harm the environment.

With solar panels now a permanent feature of your home, regular cleaning is essential. However, should you pressure wash your solar panels?

The definite answer is no, and here’s why:

Damage to the Glass

High-pressure washing uses pressurised water to deep clean surfaces. However, when used on solar panels, the pressure could cause the glass to break, allowing water to seep into the panels and cause irreversible damage.

Warranty Voiding

Some solar panel manufacturers don’t recommend pressure washing your solar panels, as it can void the warranty.

Reduced Performance

Even if the pressure does not entirely break the glass or cause damage to the panels, it can still result in subtle damage. Even the slightest amount of damage could render the panels inefficient and cause them to heat up unevenly, potentially leading to further damage.

Pressure cleaning does not help with your solar panels. Instead, you should try these tips when cleaning your solar panels:

• Use a hose when cleaning your panels. Ensure that you rinse off any dust or debris from the ground.

• Be gentle with the cleaning, and ensure you clean your panels on an overcast day or when the sun isn’t too glaring.

• Read the solar panel manufacturer guide. There should be instructions for proper cleaning and maintenance of your solar panels.
