Solar Panel Cleaning FAQs

Here are some frequently asked questions that we’ve got from our customers over time, that we’ve answered and put together on one page.

How much does it cost to clean solar panels?

Solar Panel Cleaning Cost. Solar panel cleaning typically costs £15 to £25 per panel. For cleaning, budget between £300 and £630 for a home with 20 to 25 panels. On the other hand, cleaning a house with 10 panels could run you between £150 and £250.

How do professionals clean solar panels?

Instead of using soap, which creates a residue that not only shadows panels but also attracts dirt, solar maintenance businesses like Northants Exterior Clean’ Solar Cleaning Team have discovered that utilising deionized water with a rolling or vehicle-mounted brush will effectively clean solar panels.

Is it worth getting solar panels cleaned?

Your panels’ overall efficiency will undoubtedly rise if you clean them.
Numerous statistical findings indicate that this efficiency and performance gain can be significant, reaching up to 21% in residential arrays and 60% in commercial installations.

How often do solar panels need to be cleaned?

Every six to twelve months. Solar panels should normally be cleaned every six months to a year in order to preserve their efficacy, productivity, and efficiency. Cleaning may be required more frequently, though, depending on where you live and how much filth and pollution are there.

Is it OK to pressure wash solar panels?

Pressure washers should never be used on solar panels. While they are excellent for cleaning the exterior of your home, including the roof and gutters. Yes, cleaning vast areas of solar panels is made much simpler by their high reach and pressure, but doing so runs the danger of harming the panels.

Do you need to turn off solar panels before cleaning?

Solar panels must be turned off so they can be cleaned. In actuality, washing solar panels safely is among the most crucial safety measures. A system for generating and storing power uses solar panels. You should therefore avoid getting wet around them.

Can I clean my own solar panels?

Recommended cleaning process: Fill your bucket with a 3% soap-and-water solution for the cleaning process.
To remove any loose debris, give solar panels a good rinse with clean water. Wash the surface of the panels using a soft scrubber and soapy water from a bucket or mixing sprayer. Repeatedly rinse solar panels with clean water from the hose.If you’re not comfortable climbing on your roof, you can always call a professional solar panel cleaning team.

Does heavy rain clean solar panels?

Not completely optimal, but there is a benefit. Rain may wash away pollen and dust, but it won’t necessarily wash away bird or bat droppings. It is a proven fact that unclean panels can cause a system efficiency loss of up to 25%! The good news is that wet days can aid with solar panel cleaning.

Do solar panels work if they are dirty?

Although dirt, debris, and bird droppings won’t completely prohibit the panels from working, they will operate less effectively as a whole. Therefore, maintaining clean solar panels is essential if you want to continue producing electricity and protect the environment!

What should you not clean solar panels with?

Although solar panels are sturdy, your system could be damaged if you use metal objects, pressure washers, or abrasive detergents. To clean the panels, we advise using dish soap and a sponge or squeegee.

Will vinegar damage solar panels?

Cleaning solar panels with vinegar: Is it safe? Yes! Because the acetic acid in vinegar is powerful enough to remove stubborn material without damaging your solar panels, it is a great cleaning option for solar panels.

The team very friendly and helpful when cleaning my conservatory windows. They were pretty filthy but now look spotless and have been treated so green algae won’t appear so quickly. Well priced and wouldn’t hesitate to use again.
