Does cleaning solar panels really matter?

Yes, cleaning solar panels does matter.

Over time, the surface of your solar panels will collect dust and grime.  This dust and grime will actually reduce the efficiencies of your solar panels and the amount of electrical power they will produce.  This is why it is important to clean your solar panels.

But before you go up and try and do this yourself, there are some things to note.

  • Lots of water, on a roof, with no safety equipment is a disaster waiting to happen so don’t DIY
  • You shouldn’t use chemicals on solar panels as this can damage them
  • You need to look out for wires – especially if birds or critters have been ‘nibbling’ on them
  • Special brushes should be used to clean solar panels

It is always best to leave this to the professionals to do, but rain alone will not clean your solar panels.  A bit like rain on the windscreen of your car gets it wet, but it is the windscreen wipers that clean the window.

So yes, it does matter if you do or don’t get your solar panels cleaned, but it also matters on how they are cleaned.  #leaveittotheprofessionals
