Do your solar panels need a clean?
Many homeowners underestimate the importance of cleaning their solar panels. However, failing to do so can lead to a build-up of dust, bird droppings, leaves and soot, which can lead to your panels becoming less efficient.
It’s a good idea to keep on top of a regular cleaning schedule to avoid any issues, especially if you live next to a busy road or farm, where there tends to be more dust and dirt in the air.
In this guide, we cover everything that you need to know about solar panel cleaning costs in 2026, whether you clean them yourself or hire professional solar panel cleaning services — the latter of which would be advised.

How Much to Clean Solar Panels?
Most homeowners in the UK pay around £100 to £150 for professional solar panel cleaning, but there are a few things that impact the cost.
Cleaning solar panels on a roof is usually more time-consuming and expensive than cleaning ground-level panels. Some companies offer a per-panel fee of between £4 and £15, but this sometimes comes with a minimum charge so can lead to higher costs for smaller jobs.
The final cost will usually account for the time spent travelling to your property, labour time, the equipment and materials used and of course, the scale of the job.
What's the best way to keep birds from nesting and roosting around my solar panels?
"You can put a proofing mesh around the frame, and spikes if needed."
Solar Panel Cleaning Prices
Cleaning your solar panels is far cheaper than the cost of replacing solar panels, with new solar panels costing anywhere from £2,500 to £8,500 depending on the make, model, and output.
Similarly, if you have solar roof tiles, these are even more expensive to replace — costing between £7,000 to £14,000 in material costs only — so it's far better to keep on top of your solar panel maintenance than it is to have to foot the cost of new solar tiles.
The main factor affecting the cost of solar panel cleaning is the size of the system. Below is a table showing typical costs for different sized properties:
| System Type | Typical Panels | Duration | Cost |
|---|---|---|---|
| Per panel cost | - | - | £4 – £15 per panel |
| Small system (ground-mounted or bungalow) | 6 – 10 panels | 10 – 20 minutes | £50 – £90 |
| Standard home | 8 – 14 panels | 20 – 45 minutes | £80 – £150 |
| Large home | 12 – 16 panels | 30 – 60 minutes | £120 – £180 |
| Very large system | 16 – 25 panels | 45 – 90 minutes | £150 – £250 |

Can you install solar panels in a gated front garden?
"Installing solar panels domestically should not usually require an application for planning permission, so long as the conditions and limits are met. You should also consider your location and the positioning of panels to maximise the amount of energy generated.
If you live in a listed building or designated area (Conservation Area, National Park, Area of Outstanding Natural Beauty), you should check with your Local Planning Authority before carrying out any work."

Factors That Affect Solar Panel Cleaning Costs
There are a few factors that can affect the cost of cleaning solar panels, which include:
- Number of panels - More panels usually mean higher costs
- Accessibility - Roofs that are very high or difficult to access can increase costs
- Panel condition - The amount of dirt or debris on the panels can affect how long they take to clean
- Position of the panels - Panels installed on the ground may be cheaper to clean than those on a roof
- Location in the UK - Solar panel cleaning in Edinburgh will generally cost less than in London
What Does Professional Solar Panel Cleaning Involve?
When you hire a professional, the process is typically quick, safe, and designed to protect your system.
- Inspection - The cleaner checks the panels for visible dirt, debris, or damage before starting.
- Safe setup - Equipment is set up, usually from the ground using extendable water-fed poles.
- Cleaning - Panels are gently cleaned using purified water and soft brushes to avoid scratches or residue.
- Final rinse & check - The system is rinsed and visually checked to ensure everything is clean and functioning as expected.
Many homeowners also find a professional cleaning service to be a worthwhile investment as part of their solar panel maintenance schedule, as a professional may also be able to inspect the panels to ensure they are functioning correctly at the same time.

When Should You Clean Solar Panels?
Most solar panels in the UK only need cleaning once or twice a year, but this can vary depending on your location and surroundings.
You may need a clean sooner if you notice:
- A visible build-up of dirt, dust, or bird droppings
- A dull or hazy layer over the panels
- A drop in energy output compared to usual (higher bills)
- You live near trees, farmland, or busy roads
As a general rule, if it’s been over 12 months since your last clean, it’s worth inspecting them. It might be necessary to clean solar panels after a particularly dry month, as rainwater helps remove accumulated dirt and debris.
It's worth having your solar panels cleaned regularly to maintain their efficiency and prolong their lifespan.
How difficult and how costly is it to add battery storage to an existing solar panel system?
"It depends on the system you have installed. If you check the make of the inverter and then contact the supplier, they will be able to give you the best option."
DIY Solar Panel Cleaning: Step-by-Step Guide
Cleaning solar panels yourself is possible, but safety should always come first. Roof work carries risks, so it's best to clean from the ground if possible.
Before You Start
- Check your system manual and safely shut down the system where possible
- Avoid roof access unless you are trained or experienced
- Never step directly on solar panels as this can cause them to crack or break
How to Clean Solar Panels Safely
- Use a soft brush or buy a dedicated solar panel cleaning kit
- Clean from the ground where possible using extendable equipment
- Use mild soapy water or collected rainwater
- Rinse gently to avoid streaking or residue
Best Time to Clean Solar Panels
Clean panels early in the morning or late evening when they are cool. Avoid cleaning in direct sunlight, as water can evaporate quickly and leave marks.
It’s best to clean solar panels in the spring or summer months, when there is less chance of frost or frequent rainfall.
If in doubt, hire a professional — they can safely clean and also check your system is working efficiently.
Will I Need to Hire Any Other Tradesmen for Solar Panel Cleaning?
Providing that your solar panels are in good condition and don’t need to be replaced, you won’t need to hire any other tradesmen to assist with the cleaning itself.
However, if after a thorough clean your solar panels still aren’t as efficient as they should be, you may need to contact an electrician to inspect the issue.
There are several reasons why your solar system may not be generating enough energy:
- Broken inverter
- Defective charge controller
- Faults in the solar panel itself
Faults in a solar panel can often be the most difficult issue to fix, as all the photovoltaic cells within a panel are interconnected. In a typical string system, just one faulty panel can affect the performance of the whole array. If you have any doubts about the performance of your solar panels, it would be wise to hire a professional electrician to carry out tests and find a solution.
Do I need a battery storage system when I get solar panels? If so, where does this get fitted, and how much space does it need?
"It depends if you're home a lot during the day. If you are, then a battery isn't necessarily required. If you're out during the day, then a battery would be required to store the energy so you can use it during the evening. You'd ideally have it in a garage, if not the loft. You can also fit some systems externally."
Checklist: Hiring a Solar Panel Cleaner
When looking for local solar panel cleaners near you, here are a few things to ask them before deciding who to hire:
- How much experience do they have with solar panels? It’s not the same as cleaning windows or gutters. You’ll want someone who knows how to work with the panels safely without damaging the surface or wiring.
- Do they use the correct equipment? Ask what they clean with. A decent solar panel cleaning kit uses soft brushes, purified water, and no harsh detergents that could leave residue or marks.
- Are they insured? Always ask if they have public liability insurance. Because if anything gets broken, scratched, or they slip on your roof, you’re covered.
- Can they work safely when up high? Roof access can be complicated, especially if your home is tall. So, they’ll need the right safety gear and experience, plus ladders or access platforms.
- How frequently do they advise cleaning? A couple of times a year is okay in the UK. That said, the frequency will depend quite a lot on where you live. Near trees or main roads? You might need more regular cleans. If you live in an area with heavy rainfall, you may need less frequent cleaning.
- Do they inspect as well as clean? Quite a number of specialists will also check for loose fittings, debris under panels, or even early signs of damage. So it’s always a good idea to ask — small issues caught early can save you money later.
- What’s included in the quote? Ask for a clear price breakdown from the get-go. Does the quote cover travel, water use, and full roof access?
FAQs
Could Cleaning My Solar Panels Affect the Warranty?
Some manufacturers will void the warranty if you use things like pressure washers, severe chemicals, or anything abrasive to clean your solar panels. So, check the paperwork first, then you’ll know you’re cleaning them in a way the manufacturer is happy with.
Is There Such a Thing as a Self-Cleaning Solar Panel?
Some modern solar panels marketed as “self-cleaning” use special glass or hydrophobic coatings to help rain wash off dust and light grime. However, rain on its own usually isn’t enough to remove stubborn build-up like bird droppings. Other panels integrate robotic cleaers to automatically clean the surface, but these are still quite rare and expensive.
Do I Need To Remove Snow From My Solar Panels?
Most UK homeowners don't need to remove snow from their solar panels. Because most panels are fitted at an angle, light snow just slides off or melts on its own as soon as the sun comes out. If you ever get heavy, settled snow that’s blocking the panels for days, it's worth calling in a specialist to clear it safely.
