The UK is undergoing a rooftop revolution. With new legislation and building standards favouring greener energy solutions, solar panels are becoming a common sight on newly built homes. According to a recent article in Today’s Conveyancer, solar panels may soon be fitted as standard in new builds across England. This shift marks a significant step forward in the UK’s journey towards net zero, but it also brings with it a new set of responsibilities for homeowners.
At A&S Cleaning, we’ve seen a notable increase in demand for our solar panel cleaning services, and for good reason. As more households embrace solar energy, maintaining these panels becomes essential not just for aesthetics, but for efficiency, cost savings, and long-term sustainability.
So, let’s dive into why cleaning your solar panels isn’t just a good idea - it’s a must.
The Rise of Solar in the UK
Solar panels are no longer a futuristic add-on. They’re rapidly becoming part of the mainstream housing fabric. Government initiatives and planning reforms are accelerating the shift to renewable energy, with developers encouraged to install solar technology on all new homes.
But there’s a catch: while solar panels are built to last, they’re not maintenance-free.
The more homes that include solar panels as standard, the more necessary it becomes for homeowners to understand the importance of regular cleaning and upkeep. That’s where our professional cleaning services come in.
Why Clean Solar Panels?
You might be surprised to learn that even a light layer of dust or pollen can affect the performance of your solar panels. Here's how:
Maximise Energy Efficiency
Solar panels work by converting sunlight into electricity. But if the surface is blocked by dirt, bird droppings, leaves, or other debris, less sunlight reaches the photovoltaic cells. The result? Reduced energy output and higher electricity bills. Studies have shown that dirty solar panels can lose between 15% and 25% of their efficiency. In some areas with high dust, pollution, or bird activity, the drop-off can be even more dramatic.
Protect Your Investment
Solar panels are a long-term investment, often lasting 25 years or more. Keeping them clean ensures they function optimally for their full lifespan. Neglecting regular maintenance can lead to gradual degradation, lower returns, and even invalidate certain warranties.
Avoid Long-Term Damage
Dirt isn’t just a performance issue. It can be corrosive over time. Bird droppings, for instance, are highly acidic and can etch into the glass if left unattended. Similarly, moss or algae build-up around the frame can compromise the structural integrity of the system.
Improve Aesthetic Appeal
Clean solar panels not only perform better - they look better. For homeowners who take pride in their property’s appearance (and possibly plan to sell in the future), a clean solar array helps maintain curb appeal.
DIY vs. Professional Solar Panel Cleaning
While it might be tempting to get the ladder out and give your panels a scrub, we strongly advise against DIY cleaning. Here’s why:
Safety risks
Roof work is inherently dangerous. Without the proper equipment and training, the risk of falls or injury is high.
Damage risk
Solar panels are delicate. Using the wrong tools or harsh cleaning products can scratch the surface or damage components.
Water usage
Using untreated tap water can leave mineral residues, reducing panel efficiency and causing streaks or spots.
At A&S Cleaning, we use specialist tools, purified water systems, and non-abrasive techniques to deliver streak-free, efficient cleaning without damaging your panels or voiding your warranty.
How Often Should Solar Panels Be Cleaned?
There’s no one-size-fits-all answer, as it depends on several factors:
Location
If you live near the coast (salt spray), in an urban area (pollution), or near farmland (dust), your panels may need more frequent cleaning.
Angle and tilt
Flat panels collect debris more easily and drain water less efficiently, so they may require more frequent maintenance.
Seasonality
Spring and summer often bring pollen and bird droppings, while autumn can lead to a build-up of leaves.
As a general guideline, we recommend cleaning your solar panels at least once or twice a year, but more often if you notice a visible drop in output or build-up of debris.
