Delicate issue on the use of solar street light

Now a day’s awareness about solar street light is rapidly growing traffic signals, gardens, apartments, schools, hospitals are there targets. It’s really good thing that we are maximizing our solar energy uses & trying to keep our nature cooler than before.

       But on the other side do we really making efficient energy management? Or just spending more energy to save little. there are many question arises when we talk about maintenance require for solar street light .basic assumption is that they doesn't need any maintenance but there are some issues like dust layers, theft protection, battery life, working time are still neglected. You can observe that half of them are switched off at all time, covered by thick dust layer which is considerably reduces its efficiency.

      Another main issue is that does it worth to spend money on solar street light where main utility is actually supplying power?? Or invest on solar where main electrification line is unable to rich??

      Decision is ours whether "just go for greener or be smarter”
