You never know where solar energy will turn up - for example, it is now in use for a public restroom installation in Wales.

BBC News reports that the public restrooms in the town of Llanidloes, Powys, have been fitted with two sets of solar panels. One panel is used to heat the water for the restrooms, while the other panel produces 1 kW of electricity to power the hand dryers and lights. The surplus power generated by the panels is sold back to the national grid.

The solar installation cost approximately $50,000 and was funded in part by the Welsh Assembly Government.
