You'll need a longer pole than 27ft to clean those from the ground mate. I'd say atleast 40ft, maybe a little more.
Also I'd take with a pinch of salt all the (non) info spouted on here about cleaning solar panels. Some on here are happy to sub-contract out jobs in the £50-£100 price range to fellas that supply no health and safety info whatsoever for work that 'will more than likely end in a fatality'.
Hi Deegee. For what ever reason, you seem to troll my posts on spc. You are happy to doubt what I say or make me out to be a liar. I'm not gonna lose sleep over it believe me. You too seem to be in the know about solar panels because you have contradictory info to mine and are happy to share it.
To date, how many solar panels have you cleaned?
Who have you cleaned them for?
How many contracts do you have?
You suggest that I sub jobs out for £50-£100 each. How did you reach that conclusion about my pricing?
Finally, ask some people on here who do the bigger commercial stuff for us if they have had to do any RAMS, paperwork etc to get the jobs. I think you'll find they had a lot to do.
