Jamie with regards to the risks of electrocution when asked to clean solar panels it's always wise to use the correct ppe no matter what type of wfp you decide to use as solar panels can and do fail. The individual panels are also permanently producing a dc current in any kind of daylight so can't be switched off as we know it.
First visually check for any obvious signs of damage to the panels
(If you happen to own a thermal imaging camera check for hotspots etc)
Do not continue with the clean if any faults are found and report back to the owner that it is unsafe to do so.
Wear Electricians Glove
Wear Electricians Safety Footwear
Avoid water running down the outside of the pole.
Best you don't clean solar panels when it's raining.
When attempting to clean roof top arrays from the ground/cherry picker etc with long poles be very aware of any overhead high voltage cables.
The likely hood of getting a belt off solar panels is very small but as the panels get older and/or start to fail the risk will becomes greater.
Hope this helps?
P.S the people that have attended a spc training day for steve on here you will not get any help from them either as I'm betting knowing steve they have had to signed a none discloser agreement. Bless him
