Solar Panel Cleaning Programmes

Did you know that regular, professional cleaning of your solar panels can increase your return on investment by up to 30%.

The panels at your solar installation will be exposed to all manner of dirt and pollution. If grime builds up on your panels it will prevent photons from reaching the photovoltaic cells, reducing their efficiency.

You might be thinking that rain will wash this dirt off (we do get plenty of it in these parts!), but unfortunately rain cannot clean them completely. It also brings another raft of problems, depositing minerals on the panels after evaporation, and resulting in salt build-up in coastal areas.

Skills and Equipment

Our experienced team have all of the necessary skills and equipment required to clean solar panels safely and effectively. Our equipment selection includes deionised water fed poles and specialist brush heads, which allow for thorough cleaning in a short amount of time. This makes it a much more cost-effective process. We will work in an efficient and safe manner, leaving your solar farm looking as good as new.

CCWC recently carried out some quite complex very high-level cleaning and maintenance works for us and they organised everything. Such as Traffic Management on extremely busy main roundabout and also Pedestrian management to coincide. CCWC Services made it a painless experience at a more than competitive cost, we will definitely be using them again in the very near future.

I have worked in conjunction with Lee & his team at CCWC Services for 4 years now and have always found them to provide a high quality, prompt and efficient service. Lee has always been quick to respond to emails and phone calls and his quotes are very competitively placed. I expect a lot from all of my contractors, and often have strict requirements and budgets to meet; Lee is extremely flexible and has always managed to meet my expectations with the service that CCWC Services provide. I would highly recommend CCWC Services for both their quality of work and competitive pricing structure.

Cardiff City Football Club has been using the services of CCWC for a couple of years and have to say the quality of their work is second to none. Not only do they always turn up on time and as agreed but their staff work diligently, with a smile and always leave the stadium as they found it. Coupled with the fact that their admin and contact response time is excellent I would recommend other companies to use CCWC with the confidence of a first-class service!

Don't bother wasting your time, we have a commercial property to be professionally cleaned in Pontypridd and I have been calling them since 6th Oct and every time I manage to speak to Lee Clark I have been given different stories, first I was told that he was going to be away and booked the job for 25th Oct this came and went but no sign of him so I called again on 16th Nov, first he had forgotten completely about it however he assured me that he was going to a conference the next day and will call me back on Monday 20th Nov. I am still waiting for that call. I have no intention of wasting anymore time as this people have no intention of doing any work.

We contacted CCWC services because we had just got a new 25,000sqft Warehouse that needed cleaning. The new Warehouse consisted of 3 large warehouses knocked into 1 large Warehouse. Each Warehouse had white panels all the way around that had collected so much dust, grease & dirt. I contacted CCWC and I heard back from them the same day and we arranged a meeting. I was met at the Warehouse by a lovely gentleman who was super helpful and explained in details what they would do to achieve best results. When the quote was agreed a booking was made to have a team on sight to have the work done. The two gentlemen who came on sight to do the work were again so helpful, so kind and very good working guys. They managed to finish the job in a couple of days and the outcome was stunning. I was very shocked to see the huge difference the clean had made. The panels come up like new and all the walls/panels were dust, grease and dirt free. So I was a happy lady. The whole round service from the company was 10/10 from start to finish. I would highly recommend this company for any industrial cleaning like I had. I have certainly kept this team in my "save" file as I wouldn’t hesitate in using them again. Thank you for all your hard work. Karen

How do you clean solar panels?

We use di-ionised water, this is the only method manufactures approve. We do not use chemicals do not allow your contractors to use ANY chemicals.

Do you use eco-friendly cleaning products?

We use di-ionised water, Our water has zero impurities meaning it’s cleaner than standard water. The water is cleaned through a six-stage filtration system taking out the impurities. Welsh Water has around 250ppm (parts per million of impurities) UK average can be 500 ppm making our Welsh Water one of the cleanest around; however, we clean this even further to zero ppb (that’s zero parts per billion)

What is your process for solar panel cleaning?

We use di-ionised water pumped up to the roof and clean the panels using careful elbow grease alone.

Do you offer a guarantee for the cleaning of solar panels?

Again, we set expectations depending on the state the panels are in but usually yes they come up great.

Can you provide references or testimonials from previous clients?

We have lots of client reviews and testimonials on our website

What is the best way to clean solar panels?

There is only the correct way which is with di-ionised water, we produce our own di-ionised water and bring this to site. Cleaning from the floor if this is possible or using some access equipment such as scaffold tower or MEWPS.

How often should solar panels be cleaned?

Once a year for optimal performance, though if you are in an area that has more dirt and grime perhaps next to a construction site you may think or need about more cleans, we always access and review what is best for our clients.

What are the benefits of solar panel cleaning?

Energy efficiency, this can increase the efficiency quite considerably saving you money as you generate more electricity.

Can I clean my solar panels myself?

Only if you use di-ionised water and the correct brushes and have the correct safety gear and equipment to reach your panels

How much does it cost to have solar panels cleaned?

From as little as £0.25 per metre dependent on the state of the panels, we would inspect and quote before commencing any work so you have a clear price and understanding of what we’re doing.

Are there any special considerations for cleaning solar panels?

Do not knock or move or stand on any solar panels, they should be only touched by water fed poles with a soft to medium brush head.
