Top 3 Solar Panel Cleaning Tips

January 1, 2018by sari@hello

The benefits of solar panels in Melbourne are long and numerous. However, solar panel efficiencies can be affected by dust and oils. With the unpredictable Melbourne weather, you’ll bet many Melbournians with rooftop solar are asking – Am I supposed to clean my solar panels? Today we’ll explore 3 top solar panel cleaning tips that will surely answer your solar maintenance questions!

Do solar panels require cleaning?

The short answer – Yes! Solar panels are generally self-cleaning, however, dust, oils and debris  can build up over time and impact performance. The dirt accumulates on the panel’s cells; this reduces their light absorption ability. Solar panels with less light absorption will produce less power. In addition to affecting performance, the accumulation of dirt also causes a lot of maintenance because it is difficult to clean these panels manually.

How often should I clean my solar panels?

Solar panel cleaning is a task that should be done at least once a year. It is important to clean the panels of the solar system because dirt and debris will build up, which can cause a series of problems from the reduction in efficiency to the eventual shutdown of the system.

Solar panels are also sensitive to extreme weather conditions. Areas with a lot of rain, winds and even snow will need less maintenance as the panels get washed and windblown, but dry areas may need more cleaning because rainwater may not reach all of the panels.

How do I clean my solar panels?

The safest way to do it is from the ground. If possible, use a long-handled sponge or cloth to avoid getting up on a ladder and risking injury.

Some people choose to hire a professional to wash their solar panels for them. This may be a more affordable option if you don’t have the time, equipment or knowledge to do it yourself.
