apparently you should use a softer brush head than you need for windows, and dont have you water temp on too high if hotwash

IS  THERE POTENTIAL TO SCRATCH THE SOLAR PANELS THEN RICHARD ?

[Steve_c]

Yes big time and your public liability will not pay out either. If you scratch them you can reduce the working capacity by up to 20%  in just one clean. I got this info from a guy that installs them in my home town, he said leave well alone, he say's they now never need cleaning.

THANKS FOR THE ADVICE STEVE I WILL LEAVE WELL ALONE

[Richard iSparkle]

i've heard the opposite!

i understand they need cleaning about twice a year to stay at their maximun effectiveness.

here's a brush advertised as suitable for cleaning them

i intend to start offering to clean them 

[Steve_c]

I wouldn't if i were you, first you have to alter your liability insurance to cover this and i'm told its a lot.
All i'm saying is what i have been told but a solar panel installer. As the insurance side of things i inquired when i altered mine to cover guttering washing and guttering vacuming.

thanks steve,

you re right, the dirst thing to do would be to make sure you re covered.  i hadnt thought to even check to be honest so will do that before anything else.  thanks for the advice
