Are your solar panels performing at their peak?
Over time, a layer of dust, bird droppings, pollen and traffic film builds up on the surface of your panels. Because solar cells need direct sunlight to generate power, even a thin layer of grime can lead to a 15%–25% drop in energy efficiency.
At Stewarts Cleaning Co, we provide a safe, chemical free cleaning service designed to restore your panels' output and protect your investment.

Why Professional Cleaning Matters
Many people assume that rain will wash their panels clean. However, rain often carries dust and pollutants that leave a sticky residue behind much like it does on a car windscreen.
-
Maximise Your Savings: Clean panels absorb more light, meaning more free electricity for your home and a faster return on your initial investment.
-
Prevent Hot Spots: Stubborn debris like bird droppings can create hot spots where cells overheat because they are shaded, potentially leading to long term damage.
-
Maintain Your Warranty: Many solar manufacturers require regular professional cleaning to keep your performance warranty valid.

Our Safe & Effective Process
We treat your solar array with the same precision as our high-end window cleaning. We never use harsh chemicals or abrasive tools that could scratch the specialised glass.
-
Pure Water Technology: We use de-ionised pure water that has been stripped of all minerals. This ensures a 100% streak free finish that doesn't leave limescale deposits behind.
-
Soft-Bristled Brushes: We use telescopic water-fed poles with "solar-specific" soft brushes to gently lift grime without putting pressure on the panels.
-
No Climbing Required: Our high-reach equipment allows us to clean most residential solar arrays safely from the ground or a secured ladder.
-
Visual Proof: As with all our services, we can send you WhatsApp or Email photos of your panels before and after the clean so you can see the difference for yourself.
Is it Time for a Clean?
If your panels haven't been cleaned in over a year, or if you’ve noticed a dip in your monthly energy generation, it’s time to give them some attention.
The StewartsCleaningCo Team offers standalone solar cleaning or Service Bundles if you’d like us to clean your windows and gutters during the same visit.

Solar Panel Cleaning:
Your Questions Answered
Doesn’t the rain clean them for me?
Rain alone isn't enough. It often leaves behind a film of dust, salt, and pollutants, much like it does on your car. Additionally, rain cannot remove bird droppings or lichen, which create hot spots that can permanently damage your cells and reduce efficiency.
Why do you use Pure Water?
Standard tap water in the Sussex area is hard and leaves white limescale spots when it dries. We use de-ionised pure water. Because it’s stripped of all minerals, it dries to a crystal clear, streak free finish that allows maximum sunlight to reach your panels.
Will you damage my panels or void the warranty?
No. We follow manufacturer guidelines by avoiding high-pressure washers and harsh chemicals. Our team uses only solar specific soft brushes and pure water, which protects the anti-reflective coating on your glass and keeps your warranty intact.
How often should I have them cleaned?
For most local homes, we recommend a professional clean twice a year. A Spring clean clears away winter grit and salt, while an Autumn visit removes summer pollen and dust to keep your energy production high year-round.
Do I get proof of the work?
Yes. Since you can't easily see your roof, we take the guesswork out of it. Like our gutter services, we send "Before & After" photos or videos directly to your WhatsApp or Email so you can see the results for yourself.
🔍 Free Gutter Inspection
See what we see! We provide a Free Camera Inspection with every quote in the BN area. We'll record the debris or blockages and send the footage straight to your phone.
Why not make the most of our additional services?
Don’t let blocked gutters cause damp or structural damage. We use high-reach vacuum systems to clear leaves, moss and debris from your downpipes and guttering. Our essential clearance service ensures rainwater flows freely, protecting your Sussex home from costly foundation issues and internal leaks.
Bring the light back into your home with our expert conservatory cleaning. We meticulously clean glass panels, uPVC frames and decorative cresting, removing stubborn moss, algae and traffic film. Our streak-free finish restores clarity and prevents long-term damage, ensuring your conservatory remains a bright, welcoming space for relaxation all year round.
Bring clarity back to your home with a professional window deep clean. Over time, glass accumulates pollution and stubborn mineral deposits that rain won't shift. I meticulously scrub the panes, frames, and sills, leaving a streak-free finish that floods your rooms with natural light and sharpens your curb appeal.
