Solar street lights have been available for quite a time now, having originally been designed for use in less developed or isolated areas, or perhaps places where the electricity supply has been disrupted by man-made or natural disasters.
The technology guiding the use of solar energy has progressed significantly to enable projects to be feasible throughout the world. The situation now is that street lights powered by solar energy can be simply and rapidly installed, giving the potential of many years of trustworthy use, with a minimum of maintenance required.
