ABSTRACT
The broad objective of this study is focused on analytical design and construction of automatic solar street light 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 section made by transistor, resistors, and the sensor LDR, changes controller which is made up of diode, resistors, LED, capacitor, and a 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 charge controller which essentially consists of an automatic battery charger, fed by the solar panel and a lighting controller, automated for dust to dawn operation. This street light jus designed to operate or trigger automatically at night.
