Does your locality has solar street lights, I see in some areas where solar lights are enabled, but if the Govet offer everywhere then this could save much money for them. How about in your country or city?
I can't find a solar lights in streets here, however some private limited companies already installed solar street lights that save energy for them, but the Govt is still sleeping and spending the money that comes from other sources.
These lights are for the people provided by the Government, why do people want to buy and install them at your residence? Most of the countries are coming with subsidy plans, so you can have solar lights for your home and that save you huge money.
