Do solar panels need to be cleaned after a downpour?

Whether you have a rigid rooftop array or a series of portable solar panels, it’s best to keep cleaning to a bare minimum. While rooftop panels should be fine after a downpour, call a cleaning service if in doubt. Keep it simple with water and a soft cloth for your portable panels.

Do solar PV panels need to be cleaned?

That said, most solar pv panels in the UK will not need any heavy-duty cleaning because regular rain will wash most dirt and grime off the surface, dispelling one of the myths about solar being its difficulty to clean.

How to clean a solar panel?

Many cleaning products are too abrasive for solar panels or may leave a residue that blocks sunlight, so you should choose these carefully. Try mixing a mild detergent in water, slowly adding more cleaner if you need more cleaning power. The last step in solar panel cleaning is to dry the glass and review your work.

Do solar panels need a cleaning service?

Professional cleaning companies provide a washing service and check for any damage from birds and the environment. Depending on the size of your solar panel array, position and location, you may wish to invest in a programmable sprinkler cleaning system to regularly rinse the panels.

Do portable solar panels need maintenance?

Since portable solar panels can fold away, they may need less maintenance than rigid PV panels. Wash or wipe a portable solar panel with water or a damp cloth, just like rigid panels. If you’ve been on a particularly muddy camping trip, or you’re using larger panels for home backup, you might need to give them a rinse.

Should you filter water before cleaning a solar panel?

These could leave behind smears as the water dries, reducing your panels’ efficiency, so you may want to filter your water before cleaning with it. If you’re working on a hot day, avoid using cold water, too, as the dramatic temperature shift could cause the glass to crack. Instead, use warm water and try to clean on a relatively cool day.
