Solar Street Lighting LED

1. 0 General description of a solar photovoltaic (spv) led street lightingsystem

the heart of any spv system is the solar cell, a semiconductor (silicon) device, which when exposed to sunlight produces dc electricity. A number of such solar cells are interconnected in series combination and sealed with a toughened and highly transparent front glass cover to form a solar photovoltaic module. A number of these modules, in turn, are again suitably interconnected and mounted on metal structure form a spv panel.

negligible low maintenance lead acid battery/sealed maintenance free batteries are used in solar LED power street lighting systems for the back up purpose. The spv array converts solar energy (sun light) directly into dc electricity. The electrical energy so generated, charges a storage battery through electronics controls. The stored energy in the battery is used to power the LED lighting system in night times.

electronic control sub-systems are generally used in the spv power system for ensuring trouble-free, long life operation of the battery bank.
