Some of the trees shading our solar pv have now been removed or pollarded.
Now I can see better that some of our panels covered in pigeon productions.
How to clean them? What do people here do?
Our window cleaner offers a service using an extended wand, but his price is £2 per panel for a warm water clean, and for 35 panels that is a lot - even for the 15 or so with pigeon poo it is a lot. Suspect his prices are set for 8 panels on a house roof - ours are effectively on a bungalow roof and easier to reach.
My current thought is for some kind of extending telescopic sponge mop following up a hose or power jet spraying an arc to avoid spraying under the tiles.
Ideas would be most welcome.
Thanks.
