that's a good idea too isn't it. I have solar lights in the conservatory and they do come on year round but different length of time dependent on the (strength of?) sunshine or light so it must be doable. I will take closer look at Vikki's hyperlink and see what's going on re batteries too. im sure those solar panels on roofs only have copper piping at the back of them with water passing through, charge into electricity....simples !
