Gsm Control System Of An Open Area Lighting By Using Solar Energy

Abstract

This project concerns the utilization of generated electrical power from photovoltaic solar panels for street lighting . A deep study have been conducted over system components such as photovoltaic (PV) effect , PV principles , types of photovoltaic cells, advantages and disadvantages of solar cells, characteristic curves of PV modules , specification and types of batteries and change controllers. Lighting concepts , measurements, lamp types, color temperature, color rendering index, lamp efficacy were studied. As a case study the lighting of al-hesbah street was executed . it depends on high pressure discharge lamps which are fed from the grid. We found out that the annual cost of consumed electrical energy is high. Complete new design of al-hesbah street lighting was carried out. The design consist of utilization photovoltaic solar modules off-grid system, 24 volt DC light emitting diode fixtures which are controlled and monitored by global system for mobile communication (GSM) . If hebron municipality decided to replace the current existed lighting system with the new one, it will save a lot of money after the completion of payback time which is about six years.
