Halvaei Niasar Hassan Moghbelli Department of Electrical Engineering Department of Mathematics University of Kashan Texas A&M University Kashan, P.O.Box: 87317-51167, Iran College Station, TX 77843-3368, USA firstname.lastname@example.org email@example.com Abstract- Power failures in roads and crosses cause difficulties due to non-availability oftraffic signal lights. Application of solar energy has been increased to power-up the trafficsignal lights all over the world recently. The proposes of this paper is the use of solar energyin powering traffic signal systems for rural areas with no power grid. A photovoltaic systemis used to capture the energy. The implemented system is simple, low-cost with free-maintenance. The nominal output voltage of the employed solar cell is 12 volts. Capturedsolar energy is saved into a 12 volts lead-acid battery. Instead of dc-dc converters, a circuitincluding IC regulator is used to control the flow of charge through the battery. Timing oftraffic light is carried out via AVR microcontroller. Experimental results for different anglesof radiation at different times of the day is shown in this paper. Keywords-solar cell, traffic signal light, photovoltaic, lead-acid battery, voltageregulation, microcontroller.
