Are you looking for reliable, effective, and safe solar panel cleaning that improves efficiency and protects your investment? Look no further than Exhoclean by S&E Cleaning, our dedicated external cleaning division specialising in pure water solar panel cleaning.
Keeping your solar panels clean isn’t just about appearance, it’s essential for maximising energy output and system performance. Studies show that panels can lose up to 50% efficiency if not properly maintained. Clean panels capture more sunlight, generate more electricity, and deliver instant savings on your energy bills.
During the spring and summer months, when solar generation peaks, regular cleaning becomes even more important. Dust, pollen, and bird droppings can quickly build up, creating shading that reduces efficiency. Bird droppings in particular can cause long-term damage if left untreated, as they harden and etch into the panel surface.
At Exhoclean, we use advanced Reach & Wash systems with heated ultra-pure water, ensuring a safe, chemical-free clean for your solar panels. The pure water leaves no residue or streaks, restoring your panels’ performance without risking damage to the surface, seals, or electrical components.
Our solar panel cleaning services are available to both domestic and commercial customers across Newark, Retford, Worksop, Gainsborough, and throughout Nottinghamshire, Lincolnshire & South Yorkshire.

Reach & Wash System with Heated Ultra-Pure Water, all from the Van
All of our vans are fitted with a mounted Reach & Wash System that allows our team to clean solar panels up to 65ft up, while standing safely on the ground.Â
These systems are fed exclusively by Heated Ultra-Pure Water, which eats through dirt and grime without using any chemicals or leaving streak marks. The water is produced using a combination of RO membranes and laboratory-grade di-ionisation vessels, then pumped up the water fed poles with a special brush head. Pure water cleaning provides quicker drying times, even in cold conditions and is the perfect, safe cleaning solution for all solar panels.Â
All water and power is supplied by the van, so all our team need is access to your property, we do the rest.Â

Does cleaning solar panels make a difference?
Cleaning your solar panels can make a huge difference to the amount of energy they generate. Dirt, debris, bird droppings and anything else that might settle on the surface of your panels can stop them from working effectively. This means that their output is decreased so you aren’t generating as much energy as you could be.Â
Giving them a good clean means they are able to do their job more effectively, especially during the sunnier months.
Can you use a pressure washer on solar panels?
It’s not a good idea to use a pressure washer on solar panels as it could cause damage, which can shorten their lifespan. Similarly, you don’t want to use anything abrasive or any harsh chemicals, as these could also damage the surface of the panels.
What is the best way to clean solar panels?
The simplest answer to this question is ‘gently’. A soft brush is the best option, as it will help to get rid of dirt build-up without damaging the surface of your solar panels. We use a pure water system that is nice and gentle while still being incredibly effective.
How often should solar panels be washed?
Most manufacturers recommend giving your solar panels a good clean twice a year in order to keep them functioning at their best. It’s a good idea to check them every now and then to see if they need a clean – especially if you live in an area where there is a lot of dust. At the very least, you should be cleaning your solar panels once a year.
When should you clean solar panels?
Ideally, you want to make sure that your solar panels are ready to make the most of the sunny weather, so it’s a good idea to get them cleaned at the start of spring.Â
However, as they’ll see less sun during the autumn and winter months, you want to improve their output as much as possible during these times. This is why it could also be beneficial to get them cleaned at the start of autumn.
It is also a good idea to clean them in the morning or late afternoon/evening, so the water doesn’t dry while you’re still cleaning them, as this can leave smudges and dirty streaks on your panels.
Do I need to turn off solar panels to clean them?
Yes – you should totally shut down your solar panel system before cleaning them. As they are an electrical system, shutting them off will ensure the safety of the person cleaning your solar panels.
