The Smart Way to Clean your Solar Panels

Solar panels from Jewel Renewables are a fantastic investment for your home, but if their location is on the roof of your home, this can prove difficult when it comes to cleaning them. This is a serious task that can be extremely dangerous. 

We recommend that you clean your solar panels at least once every 6 months to ensure the highest energy-generating performance in your home. But, carrying out this task can be very difficult.

Therefore, this article will guide you through how you can clean your solar panels the smart, and safe, way.

Roof Solar Panels

To Clean or Not to Clean Solar Panels Yourself

If your solar panels are roof-mounted and you can reach them yourself, by climbing onto your roof, this is a primary danger of cleaning them yourself. Without the proper equipment and training this is extremely dangerous and increases your risk of falling, damaging your solar panels and potentially electrocuting yourself. Therefore, we recommend that you don’t even try to attempt this. In addition, if your solar panels are completely unreachable, cleaning them yourself is completely out of the question.

Knowing when to clean your solar panels is also an important deciding factor. If you are finding that the electricity in your home isn’t working as efficiently as usual or you can visibly see dirt and bird droppings, then it is time for your solar panels to have a thorough clean.

The Smart Way to Clean your Solar Panels

For the homeowners that can reach your solar panels yourself by using a safe, ground-based cleaning approach, using a telescopic pole with a soft bristled brush is the best and safest option. 

But what method must you take?

The first step may seem obvious but can be easily forgotten. Turn everything off in your home and choose a time of day when it is cloudy to reduce the risk of burning your solar panels when cleaning them.

The next step is to use a garden hose with a gentle spray nozzle to hose the panels down, loosening dirt and other elements to then apply a mild soap using your telescopic brush to gently scrub your panels. Once this step has been completed, rinse your solar panels thoroughly with water and let them air dry.

Despite this method seeming quite simple and straightforward, your own safety is more important and so if this is not possible, this ground-based cleaning approach must not be taken.

Reachable Solar Panels

The Best (And Recommended) Solution

At Jewel Renewables, we recommend that hiring a professional is the best approach to take when cleaning your solar panels once every 6 months. 

A professional has the right equipment to work at heights, can do a better and thorough job and will use a proven and approved cleaning approach. This means that your solar panels won’t get damaged accidentally and an expert can often perform a visual inspection of your panels for any potential issues.

At Jewel Renewables, even though we don’t have an in-house solar panel cleaning team, we can still refer you expert advice to help you take care of things and keep you safe from any cleaning accidents. Contact us today and a member of our team will be happy to assist you.

Maximise your Solar Panel Investment Safely

A regular cleaning of your solar panels once every 6 months will help boost the performance and efficiency of your home, however, safety should always come first, even if you can access your own roof-mounted solar panels.

We recommend hiring a professional as this will not only keep you safe, but it will also save you money in the future by not having to keep cleaning them regularly due to an ineffective DIY job.
