    • ABSRACT - [ Total Page(s): 1 ]In this project work, we are mostly concern about building a simple power streetlight which is automatically operated. There are four main components required to build a solar operated streetlight. The solar array, High efficiency D.C lamp, changes controller and battery of which the solar array is the most expensive. It is the solar array that produced a D.C voltage due to the energy received from the sun during the day , thereby making the battery to charge, as a result, keeping the streetlight into operation when it get dark. The basic circuitry on solar powered streetlight is the solar cha ... Continue Reading

         

      CHAPTER ONE - [ Total Page(s): 2 ]The charge controller projects the battery from over-charging, maximizes the charging voltage and current output of the solar panel.            To achieve the automatic operation of the streetlight, a photocell or a time, which senses the period of darkness and lightness, is used to trigger.            The type of battery employed here is a maintenance free one, which is capable of supplying few days of back up power in case of bad weather or charger failure. Also the lamp used in this project work is a D.C operated lamp.1.1       BACKGROUND OF THE STU ... Continue Reading
