As a renewables organisation, in our humble opinion, installing solar panels is obviously a smart move, one that reflects your or your business commitment to sustainability and long-term savings. Whilst renewable systems are of course, lower maintenance, a little care now and then can make a big difference. That extra attention helps your panels perform at their best, especially as we head into the darker, wetter winter months.


With this in mind, solar panel cleaning has gained popularity over the past few months, and you might be wondering, “What’s all the fuss about?” That’s where we come in. Let’s break down some key facts and information about the cleaning process to help clear up any confusion or questions you may have…

Do My Solar Panels Actually Need Cleaning?

It’s tempting to think that the (unfortunately frequent) rain across the nation does the job for you. And yes, it does help remove some dust, but those sticky tree sap spots, accumulated pollen, or airborne industrial grime require something a little more powerful to be removed effectively! 

You might be thinking, “I could clean these myself,” but solar panels are delicate, and accessing them safely often requires working at height. Our team uses specialised equipment and eco-friendly products to make sure your solar panels are left sparkling clean—all while keeping safety front and centre. So no need to worry if you’re afraid of heights!

How Often Do My Solar Panels Need Cleaning?

The simple answer is that regular maintenance drastically reduces future costs. Allowing hard soiling and stubborn biological growth (like moss or lichen!) to set in means the eventual removal process requires harsher methods, more time, and becomes significantly more costly….we recommend at least one yearly clean, usually before or after winter, to keep your system in top shape and ready for the unpredictable weather ahead.

What Are the Benefits?

.Making the decision to professionally clean your solar panels is, fortunately, an investment that pays back. With clean solar panels generating up to 20% more electricity than dirty ones, the cost of cleaning is quickly reinvested in energy savings!

Cleaning also helps protect the long-term health of the panels. That hard soiling and dirt we mentioned can cause hotspots, where shaded cells overheat due to disrupted current flow. Over time, this can damage your panels and shorten their lifespan. Keeping them clean reduces build-up, helping to mitigate the risk of issues and protect your investment.

And let’s be honest – they also look a lot better. A wonderful badge of pride for any eco-conscious home or business. Just look at that before and after!
