Solar Powered Streetlight

The Solar powered streetlight system for residential streets, campus roadways, dark intersections, as well as parking lots and general area security lighting applications.
This system can bring illumination to troublesome locations where it is difficult, expensive or impossible to run power lines. There is no need for electric meters and monthly bills, power company charges for bring electricity to the site, land use permission issues for carrying power across properties, or the inevitable delays caused by all these factors. Installation is easy and the system is virtually maintenance free.

The solar module of the system converts sun light into DC power. This DC power is used to charge the lead acid battery. During the night time, the DC power from the battery is inverted to high frequency AC by the inverter and is fed to the Three-Wavelength Fluorescent lamp.

A microprocessor controls the functions of the system automatically activates from sunset to sunrise, also has a timer, regulating the hours the light stays on.

Charge regulator as a part of the electronics will monitor the battery operating conditions and improve the battery performance and life time also preventing overcharging and protecting against discharging.
