How it works
A streetlight is a raised source of light by the roadsides; it is turned on by someone at nightfall and turned off at the break of dawn. It cables requires replacement once in a while due to damages from construction diggings etc. Whereas, a solar streetlight on the other hand does all of the above without human intervention whatsoever. It is completely maintenance free and uses the power of the sun in place of the grid. In other words, you only pay the initial cost and the system runs on free energy for the rest of it life.Except for occasional dusting of it modules.
