Why Clean Solar Panels?

Increase Energy Output

Solar panels are designed to absorb sunlight and convert it into electricity. However, if your solar panels are dirty, the amount of sunlight that can be absorbed is reduced. This decreases the potential energy output. According to the National Renewable Energy Laboratory, dirty solar panels lose between 7 and 50 percent energy output. The amount of dirt on panels increases over time, so the longer it has been since your last clean, the better the results you are likely to receive.

Extend Lifespan Of Your Solar Panels

Dirt and dust can build up on your solar panels over time and cause them to wear down. This can shorten the lifespan of your solar panels on top of reducing their overall efficiency. Cleaning your solar panels regularly can help to prevent this from happening and extend their lifespan. Solar panels are designed to last for around 50 years, but that number is dependant on how well they are looked after. It's like brushing your teeth.

Protect Your Investment

Solar panels are a significant investment, and it is important to protect your investment by cleaning them regularly. Dirty solar panels reduce your energy output and shorten their lifespan, which can cost you money in repairs or replacements in the long run. Cleaning your solar panels regularly can help ensure you are getting the most out of your investment. It's like dry cleaning your nicest clothes, rather than washing them in rainwater.

Look Better

Dirty solar panels can make your home look run down and dingy. Cleaning your solar panels helps improve the appearance of your home and make it more inviting, and easier to sell.

Maintain Your Warranty

Many solar panel manufacturers require you to clean your solar panels regularly in order to maintain your warranty. The warranty is important as it can cover the cost of repair or replacement.

Prevent permanent damage

If you live in an area with hard water, it is important to clean your solar panels more often, to prevent water spots and staining from hard water rain that can reduce efficiency permanently.

How We Clean Your Solar Panels

The steps we take to get the shine back on your solar setup

1

Roof access

Before any cleaning can begin, it is important to ensure safe access to the roof. This is especially important if the solar panels are installed on a steep or slippery roof. Our team of experienced technicians is trained in safe roof access procedures and will always use a safety harness when working on your roof.

2

Rinse and brush

Once we have safely accessed the roof, we will begin by rinsing the panels with pure deionised water. This will remove any loose dirt and debris. We use a soft brush to gently loosen any remaining dirt or grime.

Specialist solution

Next, we will clean the panels with our specialist solar pv compliant solution. We use ChemiTek Lichen removal agent and ChemiTek Solar wash protect which is sprayed on before cleaning and then rinsed away with pure deionised water. We are careful not to use harsh chemicals or detergents, as these can damage the solar panels.

Solar Panel Cleaning FAQs

Do solar panels really need to be cleaned?

Yes. Dust, bird droppings, pollen and grime can block sunlight and reduce efficiency. Clean panels work better and last longer.

How often should solar panels be cleaned?

We recommend a professional clean once or twice each year. In areas with heavy dust, pollution or bird activity, more frequent cleaning may be beneficial.

What is the best way to clean solar panels?

Use a soft brush and purified or deionised water to gently remove dirt. Avoid harsh chemicals or high‑pressure washers. Hiring a professional helps protect your system and warranty.

Can I clean solar panels myself, or should I hire a professional?

You can clean panels yourself if safe access is possible and the right tools are used. However, professional cleaning ensures safety, uses purified water and non-abrasive methods, and helps protect your system and warranty.

What is the best time of day or year to clean solar panels?

Early morning, evening, or cloudy days are ideal to avoid thermal stress on hot glass. In the UK, spring and autumn are popular for routine cleans.

Is rain enough to keep my solar panels clean?

Rain rinses light dust but won’t remove sticky residues such as bird droppings, sap or lichen. Periodic cleaning is still recommended to maintain output.

What products and tools are safe to use on solar panels?

Use purified/deionised water with a soft-bristle brush or squeegee. Avoid abrasive pads, ammonia-based cleaners and pressure washers to prevent damage.

Can cleaning hot panels cause damage?

Yes. Spraying cold water on very hot panels can create thermal stress. Always clean when panels are cool to the touch.

Are there new technologies for solar panel cleaning?

Yes. Options include hydrophobic anti-soiling coatings and robotic or automated cleaners for large or hard-to-reach arrays. We can advise on suitability for your system.

How much does professional solar panel cleaning cost?

Prices vary based on the size of your array, its location and ease of access. Contact us for a tailored quote and we’ll happily provide a clear, no‑obligation estimate.

Can I walk on solar panels or clean them with tap water?

No. Walking on panels risks cracking the glass and damaging connections. Tap water often leaves mineral deposits; purified water is best. Let trained technicians handle the job safely.

Does rain clean solar panels?

Rain may rinse some dust away, but it can’t remove stubborn dirt or bird droppings. Regular cleaning ensures your panels stay in top condition.

What should I avoid when cleaning solar panels?

Do not use abrasive tools, harsh chemicals, pressure washers or stand on the panels. These can scratch or damage the surface and reduce performance.
