Are you trying to find solar panel cleaning services? Trusted Tradesman helps you find local solar panel cleaners and specialists who can clean photovoltaic panels and help keep your solar PV system operating effectively.

Solar panels are designed to spend their working lives outdoors, so they inevitably become exposed to dust, pollen, bird droppings, leaves, pollution and other airborne debris. Rain can wash away some surface dirt, but it does not necessarily remove everything that accumulates on a solar panel.

For many properties, occasional natural rainfall may be sufficient to keep panels reasonably clean. However, where panels have become visibly dirty or their position exposes them to unusually high levels of contamination, professional cleaning may be worthwhile.

Trusted Tradesman makes it easier to find solar panel cleaning companies near you. Search by location to find local businesses offering solar panel cleaning and related solar PV services.

Why Do Solar Panels Need Cleaning?

Solar panels are exposed to the elements throughout the year. Although rainfall naturally washes some dirt from their surface, contaminants can remain behind.

Depending on the property’s location and surroundings, panels may accumulate:

  • Dust
  • Pollen
  • Bird droppings
  • Leaves
  • Moss and organic material
  • Airborne pollution
  • Traffic-related grime
  • Tree debris
  • General environmental dirt

Some contaminants are more problematic than others. Bird droppings, for example, can create concentrated areas of shading on the panel surface. Leaves and other debris can also cover sections of a panel.

Because photovoltaic panels generate electricity from sunlight, anything that significantly obstructs sunlight from reaching the cells has the potential to reduce generation.

Do Solar Panels Need Cleaning?

Not necessarily on a fixed schedule.

One of the important points to understand about solar panel cleaning is that not every installation needs regular professional cleaning. The amount of dirt that accumulates depends heavily on the location, angle and surroundings of the panels.

Panels installed at a reasonable angle can benefit from rainfall washing away loose dirt. In many domestic installations, occasional natural rainfall may therefore keep the panels sufficiently clean for normal operation.

However, this does not mean that cleaning is never necessary.

If your panels are visibly dirty, have accumulated bird droppings, are underneath trees, are close to agricultural activity or are located in an environment where dust and pollution accumulate, cleaning may be beneficial.

The best approach is to consider the actual condition of the panels rather than automatically paying for cleaning at a predetermined interval.

Does Cleaning Solar Panels Improve Their Performance?

Cleaning can improve solar panel performance when dirt or other contamination is obstructing sunlight from reaching the photovoltaic cells.

However, the potential improvement varies significantly from one installation to another.

A lightly soiled panel that receives regular rainfall may see little measurable difference after cleaning. A heavily contaminated panel covered by bird droppings, dust or other debris may benefit considerably more.

Solar generation also varies naturally throughout the year because of weather conditions, daylight hours, temperature, shading and the position of the sun. It is therefore important not to assume that a change in electricity generation following cleaning is entirely attributable to the cleaning itself.

The Energy Saving Trust notes that solar panels generally require little maintenance and that cleaning may be necessary where dirt is affecting performance. ([energysavingtrust.org.uk](https://energysavingtrust.org.uk/solar-panel-cleaning-maintenance/?utm_source=chatgpt.com))

How Often Should Solar Panels Be Cleaned?

There is no universal cleaning interval that applies to every solar installation.

Some domestic solar panels may go for years without requiring professional cleaning, while panels in particularly dirty environments may need attention more frequently.

Factors that can influence cleaning requirements include:

  • The angle of the panels
  • The local climate
  • The amount of rainfall
  • The presence of trees
  • Bird activity
  • Nearby roads
  • Industrial or commercial activity
  • Agricultural activity
  • Airborne dust
  • Local pollution levels
  • The accessibility of the panels

Rather than assuming that solar panels need to be cleaned every year, inspect their condition and consider whether contamination is likely to be affecting performance.

A solar panel cleaning professional may also be able to advise whether your particular installation would benefit from periodic cleaning.

Bird Droppings on Solar Panels

Bird droppings are one of the more common reasons why individual areas of solar panels can become heavily contaminated.

A small amount of dirt spread across a large panel may have relatively little effect, but a concentrated deposit can block sunlight from reaching part of the panel.

Bird droppings can also be difficult to remove once they have dried onto the surface.

For panels installed on a roof, attempting to reach individual areas with a hose, ladder or improvised cleaning equipment can create unnecessary risks. A professional solar panel cleaner can use suitable equipment and access methods to clean the panels without putting the property owner at risk.

Solar Panel Cleaning and Trees

Properties surrounded by trees can present particular challenges for solar panel owners.

Leaves, pollen, seeds and other organic debris can accumulate on panels, while birds may also be attracted to nearby trees.

Overhanging branches can create another issue: shading.

Cleaning cannot solve a problem caused by permanent shading from trees or nearby structures. If panels are regularly shaded, the underlying cause may need to be addressed separately.

If you are unsure whether your solar generation problem is caused by dirt, shading or an equipment fault, consider finding a solar PV specialist who can inspect the system rather than simply arranging a cleaning visit.

Solar Panel Cleaning for Domestic Properties

Domestic solar panels are often installed on pitched roofs, garages, extensions or other elevated areas.

This can make cleaning considerably more difficult than it appears from ground level.

Even if the panels are visibly dirty, accessing them safely can require appropriate ladders, access equipment or specialist cleaning equipment. Walking directly on solar panels is also not an appropriate method of cleaning them.

A professional solar panel cleaning company can assess access to the installation and determine the safest practical way to clean the panels.

This is particularly important where panels are installed on steep roofs, high buildings or areas with limited safe access.

Commercial Solar Panel Cleaning

Commercial solar installations can contain dozens, hundreds or even thousands of panels. Keeping a large PV array clean can therefore be considerably more involved than cleaning a small domestic system.

Commercial solar panel cleaning may be relevant to:

  • Factories
  • Warehouses
  • Offices
  • Retail premises
  • Farms
  • Agricultural buildings
  • Schools
  • Hotels
  • Industrial units
  • Public buildings
  • Large commercial rooftops

For commercial installations, cleaning may form part of a wider planned maintenance programme. A business may also wish to monitor generation before and after cleaning to determine whether the work is providing a worthwhile return.

Commercial cleaning companies should be able to discuss access requirements, working-at-height considerations and the most appropriate cleaning method for the installation.

Solar Panel Cleaning for Farms and Agricultural Buildings

Solar PV systems are increasingly found on agricultural buildings, where large roof areas can provide suitable space for photovoltaic installations.

Agricultural environments can also expose panels to additional airborne dust, dirt and organic material.

Dust from fields, farm machinery and agricultural activity can settle on panels, potentially increasing the need for inspection and cleaning.

Where a farm has a large rooftop solar installation, professional cleaning can be considered as part of the wider maintenance strategy for the PV system.

How Are Solar Panels Cleaned?

Professional solar panel cleaning methods vary according to the installation, access requirements and level of contamination.

The objective is to remove dirt without damaging the panel surface, seals, frame or other components.

A professional cleaner may use specialist equipment designed for photovoltaic panels, together with suitable water and cleaning techniques.

In many circumstances, the aim is to avoid leaving residues or deposits on the panel surface once cleaning is complete.

The precise method used should take account of the manufacturer’s recommendations and the condition of the installation.

Can You Pressure Wash Solar Panels?

Pressure washing is generally not something that should be attempted casually on a solar PV installation.

Solar panels are manufactured for outdoor use, but that does not mean every component of the installation should be subjected to high-pressure water.

High-pressure water can potentially cause problems if directed at seals, connectors, junction boxes or other vulnerable parts of the installation.

Rather than using a domestic pressure washer, it is preferable to use a cleaning method appropriate for photovoltaic equipment and the particular installation.

Can You Use Tap Water to Clean Solar Panels?

Water quality can be relevant when cleaning solar panels.

Depending on the local water supply, ordinary tap water can contain minerals that may leave deposits on a panel when the water dries.

Professional solar panel cleaners may therefore use water-treatment systems or other methods intended to minimise residue on the panel surface.

If you are considering cleaning your own panels, follow the manufacturer’s recommendations and avoid using cleaning products or methods that could damage the panel surface or other components.

Should You Use Soap to Clean Solar Panels?

Solar panels should not automatically be cleaned with household washing-up liquid or other domestic cleaning products.

Residues left behind after cleaning can attract further dirt, while unsuitable chemicals could potentially damage surfaces or components.

A specialist solar panel cleaner will be familiar with appropriate cleaning methods and equipment.

If a manufacturer’s instructions specify particular cleaning requirements, those instructions should take precedence.

Is It Safe to Clean Solar Panels Yourself?

The biggest issue with domestic solar panel cleaning is often not the panels themselves but access to the roof.

Attempting to clean rooftop solar panels from a ladder or by climbing onto a roof can introduce significant fall risks.

The Health and Safety Executive provides guidance on work at height and stresses the need to properly assess risks and use suitable equipment when working at height. ([hse.gov.uk](https://www.hse.gov.uk/work-at-height/index.htm?utm_source=chatgpt.com))

For this reason, homeowners should carefully consider whether cleaning the panels themselves is worthwhile, particularly where the panels are installed on a steep or difficult-to-access roof.

Professional cleaning can remove the need for the homeowner to work at height and can also provide an opportunity for a trained professional to identify visible problems with the installation.

Solar Panel Cleaning vs Solar PV Maintenance

Cleaning and maintenance are related but they are not the same service.

Solar panel cleaning primarily involves removing dirt and other contaminants from the panel surface.

Solar PV maintenance is broader and can involve assessing the condition and performance of the wider installation.

Maintenance may include consideration of:

  • Panel condition
  • Mounting equipment
  • Electrical connections
  • DC cabling
  • Inverter operation
  • System performance
  • Monitoring equipment
  • Battery storage
  • Signs of deterioration

If your main concern is that the panels are visibly dirty, a solar panel cleaning company may be appropriate.

If your concern is that the system is generating significantly less electricity than expected, it may be more appropriate to arrange a solar PV inspection or maintenance visit.

You can find out more on our Solar PV Maintenance page.

Solar Panel Cleaning vs Solar Panel Repairs

Cleaning will not resolve an electrical or mechanical fault.

If your inverter is displaying an error code, your system has stopped generating electricity, panels are physically damaged or monitoring has stopped working, you may need a solar panel repair specialist rather than simply a cleaner.

It is possible, however, for a cleaning professional to identify obvious physical problems while carrying out their work and advise that further specialist investigation is required.

Can Dirty Solar Panels Cause a Fire?

Dirt on the surface of a solar panel is not normally considered the primary cause of a solar PV fire. However, solar PV systems contain electrical components that require appropriate installation, inspection and maintenance.

If you see damaged panels, exposed wiring, signs of overheating, scorching or other unusual conditions, do not treat the problem as simply a cleaning issue.

Arrange an assessment by an appropriately competent solar PV or electrical professional.

The Building Safety Regulator’s research into solar photovoltaic panels and fire safety highlights the importance of considering the electrical characteristics and installation of rooftop PV systems. ([gov.uk](https://www.gov.uk/government/publications/fire-safety-solar-photovoltaic-panels-on-roofs?utm_source=chatgpt.com))

Solar Panel Cleaning Cost

The cost of cleaning solar panels depends on the size of the installation, the number of panels, the location, accessibility and level of contamination.

A small domestic installation on an easily accessible roof may be relatively straightforward, while a large commercial rooftop may require specialist access equipment, additional labour and more extensive cleaning.

Other factors that can affect the price include:

  • Number of panels
  • Roof height
  • Roof pitch
  • Ease of access
  • Amount of dirt and contamination
  • Bird droppings
  • Tree debris
  • Commercial or domestic location
  • Travel distance
  • Whether additional inspection is requested

Because installations vary so much, obtaining a quotation based on your particular property is usually more useful than relying on a generic solar panel cleaning price.

Is Solar Panel Cleaning Worth It?

Whether cleaning is worthwhile depends on how dirty the panels are and how much the contamination is affecting their performance.

For a lightly soiled domestic installation that receives regular rainfall, professional cleaning may produce only a small improvement.

For panels with substantial bird droppings, dust or other contamination, cleaning may be more worthwhile.

For commercial installations producing significant quantities of electricity, even a relatively modest reduction in generation can have a financial impact, making performance monitoring and maintenance more important.

The sensible approach is to consider the actual condition and performance of your installation rather than assuming that every solar panel system requires frequent cleaning.

When Should Solar Panels Be Cleaned?

There is no single best time of year to clean every solar panel system.

Some property owners choose to arrange cleaning when panels have accumulated visible dirt, while others include cleaning within a broader maintenance programme.

Spring can be a practical time to inspect panels after the winter months, particularly where trees and vegetation have contributed debris. However, the appropriate timing depends on the individual installation.

If you notice heavy contamination at any time of year, there is no need to wait for a particular season before seeking advice.

Signs Your Solar Panels May Need Cleaning

Visible dirt is the most obvious indication that cleaning may be appropriate, but there are other clues to consider.

Possible signs include:

  • Heavy bird droppings on the panels
  • Visible layers of dust
  • Leaves or organic debris accumulating on the panels
  • Panels underneath trees becoming heavily contaminated
  • Persistent dirt remaining after rainfall
  • A noticeable change in panel appearance
  • Generation falling when compared with previous performance under similar conditions

However, a reduction in generation should not automatically be blamed on dirt. Seasonal changes, cloud cover, shading and equipment faults can all affect output.

Frequently Asked Questions About Solar Panel Cleaning

Do solar panels need cleaning?

Not every solar panel system needs regular professional cleaning. Rain can remove some surface dirt, and panels installed at an appropriate angle may remain relatively clean. Cleaning can nevertheless be worthwhile where panels have accumulated substantial dirt, bird droppings or other contamination.

How often should solar panels be cleaned?

There is no fixed interval that applies to every installation. Cleaning requirements depend on factors including rainfall, panel angle, trees, birds, pollution, dust and the surrounding environment.

Does rain clean solar panels?

Rain can remove loose dirt from solar panels, but it does not necessarily remove all contaminants. Bird droppings and more persistent deposits may remain after rainfall.

Can dirty solar panels reduce electricity generation?

Yes. Dirt and other contaminants can reduce the amount of sunlight reaching photovoltaic cells. The effect depends on the type and amount of contamination and the characteristics of the installation.

Can I clean my solar panels myself?

You can potentially clean panels that are safely accessible, but rooftop access creates significant fall risks. If panels are difficult or dangerous to reach, professional cleaning is usually the safer option.

Can I use a pressure washer on solar panels?

Using high-pressure water on a solar PV installation is not recommended as a casual DIY cleaning method. A specialist cleaning approach should take account of the panels, seals, connectors and other components.

Can I use washing-up liquid on solar panels?

It is better not to use ordinary household cleaning products unless the panel manufacturer specifically recommends them. Residues and unsuitable chemicals may create problems, so appropriate cleaning methods should be used.

How much does solar panel cleaning cost?

Prices vary according to the number of panels, property height, access, roof pitch, contamination and whether specialist equipment is required. Requesting a quotation from a local solar panel cleaning company is the best way to establish the cost for a particular installation.

Does cleaning solar panels improve efficiency?

Cleaning can improve generation where dirt is significantly obstructing sunlight. The improvement will vary depending on how contaminated the panels were before cleaning.

Should solar panels be cleaned in winter?

There is no general requirement to clean panels specifically in winter. Cleaning should be based on the condition of the installation and whether contamination is likely to be affecting performance.

Do solar panels need cleaning after installation?

A newly installed system should normally be clean when installation is complete. Cleaning requirements develop over time as the panels become exposed to the outdoor environment.

What is the difference between solar panel cleaning and maintenance?

Cleaning removes dirt and contamination from the panel surface. Maintenance is a broader service that can involve inspecting the panels, electrical equipment, inverter, cabling, monitoring system and other components.
