Whilst cleaning some very dusty and dirty solar panels this morning, I got to thinking…

Q. Why are solar panels covered with a grid pattern?

A. To provide the pigeons with a more challenging target area.

I am trying, so far unsuccessfully, to get an answer to the simple question namely is it legal (given the hosepipe ban) to use a hose to clean ones own solar panels. 

Affinity water have confirmed that it is legal for someone to do this as a business, but have not answered the question about DiY.  The actual legal notice would suggest that it is legal, unless solar panels are an artificial outdoor surface.  Obviously mathematically solar panels are a 'surface' but I would personally say that they are not a 'surface' in the way normally meant in the context of building.

 

The precise definition is

 

(k) Cleaning other artificial outdoor surfaces using a hosepipe

“Artificial outdoor surface” means any of the following:
a) any area outdoors which is paved or laid with hard or artificial material;
b) timber decking;
c) a quay;
d) a trailer designed, constructed or adapted to launch boats or other vessels or craft into water, other than a private motor-vehicle;
e) the roof of any domestic premises. “Quay” includes jetty, pontoon, wharf and slipway.

Interpretation: It is interpreted to include the cleaning by hosepipe of all exterior surfaces, by domestic customers. This includes driveways (both domestic and non -domestic); and marine infrastructure such as pontoons and slipways, whether fixed permanently in position or floating
.
