Solar Panel Cleaning Exeter
Professional Solar Panel Cleaning in Exeter & Devon
We provide professional solar panel cleaning throughout Exeter and the surrounding areas, helping homeowners and businesses keep their solar panels clean and well maintained.
Over time, solar panels can accumulate dirt, dust, bird droppings, pollen, algae and other organic deposits. This build-up can reduce the amount of sunlight reaching the surface of the panels and may affect their performance.
We use purified water and professional water-fed pole equipment to gently clean solar panels without leaving behind the mineral deposits and residues associated with ordinary tap water.
Our high-reach equipment also allows us to clean many solar panel installations safely from ground level, where access permits.
Solar panel cleaning can be booked as a one-off service or as part of a regular maintenance programme.
Covering Exeter & Surrounding Areas
Why Have Your Solar Panels Professionally Cleaned?
Solar panels are constantly exposed to the elements and can gradually accumulate bird droppings, dust, pollen, algae and other deposits. Rainfall can remove some loose dirt, but more stubborn contamination can remain on the surface of the panels.
Professional cleaning helps keep the panels clear of this build-up and allows as much available sunlight as possible to reach the surface.
Our solar panel cleaning service includes:
-
Purified water to avoid leaving mineral deposits or residues on the glass
-
Professional water-fed pole equipment for gentle, non-abrasive cleaning
-
High-reach cleaning from ground level wherever safe access allows
-
Careful removal of bird droppings and other stubborn contamination
-
One-off and regular maintenance options
-
An experienced, fully insured local cleaning team
We do not use abrasive brushes or harsh cleaning methods that could unnecessarily risk damaging the surface of the panels.
Solar Panel Cleaning FAQ
How often should solar panels be cleaned?
There is no single cleaning schedule that suits every solar panel installation. How often cleaning is needed depends on factors such as surrounding trees, birds, nearby roads, roof angle and the amount of dirt and organic material that accumulates. For many properties, an annual clean may be sufficient, while panels particularly affected by bird droppings, trees or other contamination may benefit from cleaning every six months. We can assess the condition of your panels and recommend a sensible cleaning frequency rather than cleaning them more often than necessary.
How much does solar panel cleaning cost?
Our regular solar panel cleaning typically starts from around £3–£5 per panel, depending on the number of panels, their location and accessibility. One-off cleans and more difficult installations are individually priced, as the time and equipment required can vary considerably. We will provide a clear quotation before carrying out the work.
Does cleaning solar panels improve their performance?
Dirt, dust, bird droppings and other deposits can reduce the amount of sunlight reaching parts of a solar panel. Cleaning removes this contamination and helps ensure the surface is clear to receive available sunlight. The effect on electricity generation varies considerably between installations and depends on how dirty the panels were beforehand, so we don't promise a particular increase in energy output.
Do you use chemicals to clean solar panels?
We primarily use purified water and professional water-fed pole equipment to clean solar panels, avoiding the mineral deposits that ordinary tap water can leave behind. We avoid harsh or abrasive cleaning methods. If an installation has unusual or particularly stubborn contamination, we will assess the appropriate cleaning method before proceeding.
Can you clean solar panels from the ground?
Yes. Our professional high-reach water-fed pole equipment allows us to clean many roof-mounted solar panel installations safely from ground level. Access, height, roof layout and the position of the panels vary between properties, so we assess each installation to make sure the panels can be reached and cleaned safely and effectively.
Do I need to be at home when you clean my solar panels?
Usually, no. As long as we have safe access to the property and the areas required for cleaning, we can normally complete the work while you're out. We will let you know beforehand if we require access to anything specific at your property.
Can you remove bird droppings from solar panels?
Yes. Bird droppings are one of the common types of contamination we encounter on solar panels and can often be removed using purified water and professional cleaning equipment. Heavier or long-established deposits may require additional attention, and we'll always use an appropriate method rather than aggressive or abrasive cleaning.
Do you clean commercial solar panels as well as residential systems?
Yes. We provide solar panel cleaning for both residential and commercial properties in Exeter and the surrounding areas.
Larger or more complex installations are assessed individually so we can consider access, panel numbers, working conditions and the most appropriate cleaning method before providing a quotation.
