Solar panels require regular cleaning and maintenance in order to perform at their peak efficiency. As solar panels are exposed to the elements, dirt, grime, debris, and more end up splattered all over the protective glass. This blocks the sun from effectively shining through to the sensors beneath, reducing the amount of power your panels can capture.

This power reduction can often be significant. We have seen some people receive a 60% boost in power output from their panels after a clean. Generally, most people could see a 10-30% increase depending on the condition of their panels.

As solar panels are a long-term investment, having them cleaned will enable them to continue performing at their best throughout their lifespan.

It is recommended that your panels are cleaned at least once a year. It has been found that a yearly clean could improve energy output by as much as 12% versus panels only cleaned by rainfall. This is because rainfall contains dust, which when dry, will stick to the surface of your panels, reducing effectiveness.

Hosing down your solar panels is not the most effective method for cleaning them, and in some cases could damage your panels. As hoses use tap water there is a lot of hard minerals which will deposit on the panels, reducing effectiveness. As well as this, hosing down your panels tends to only clean off the top layer of dirt, meaning that your panels are still performing below their maximum potential.
