Correction: Not all solar panels are suitable to walk on*
Just like cleaning your windows to let in more light, it is also worth adding your solar panels to the window cleaning schedule.
Remember – the more light getting to the solar cells means the more electrons are knocked loose, which means your solar panels will generate more electricity.
Leaves, bird mess, dust/sand can build up on your solar panels and reduce the amount of light getting to the solar cells.
Solar panels are incredibly tough. They are built to withstand severe hailstorms to installers walking on them during installation. You will not be able to break them without considerable effort.
We advise spraying them with water to wash away dust/sand/leaves. Solar panels are water repellent so they will clean themselves when it rains, however, there might be a long dry spell, or a stubborn leaf, so it’s good to keep on top of things.
For more stubborn dirt, we suggest using a long pole with a soft brush at the end or asking your window cleaner to also clean the solar panels – they are just incredibly tough windows after all!
Ignore them. Do not respond and block their phone number.
Solar panel cleaning shouldn’t cost more than your existing window cleaner, who may not even charge extra to brush your solar panels if you ask nicely!

One of the many reasons I started Leoht was because a family member (88 years old) was convinced by a company that would not leave his home, to pay £2000 for a solar panel cleaning and maintenance check. Unfortunately, there are people who will seek to take advantage, which is why Leoht writes so many of these articles - helping consumers make educated choices.
Always check if they’re MCS certified or a member of the RECC.
