have you ever considered cleaning your PV Panels ?

I only ask because the local shops had an man out this morning with his access platform and a squeegee giving them a clean

AFAIK they have a special coating on them that self-cleans when it rains?
We have the water heating type and these have a coating

I assumed they would have a coating , but he was defo cleaning them. I guess someone had noticed a drop in efficiency , enough to warrant trying a clean

........or he blagged an unnecessary cleaning job?

Have been told that panels at an angle of more than something like 30 degrees don't get dirty enough to warrant cleaning them.
Google has commented on it. Official Google Blog: Should you spring clean your solar panels?
