Solar panels seem to be popping up everywhere as a form of cheap(er) energy, especially for small projects. It all seems a bit hopeful, bearing in mind that the weather has been so grey and rainy over the last week; but I'm told they do earn their keep.
This one is perched on top of a brick shed which encloses what I think is a small sluice controlling the flow of water through a small ditch. (I think...)
Seems a rather clever way to me of powering a low-energy need.
