Design and testing of a solar-operated clock for campus use

In this work the design and testing of a solar-operated clock system for campus use has been implemented. The design uses three solar panels each of 130W capacity and two solar batteries each of 200AH/12V capacity to power four identical giant quartz clocks synchronized to keep uniform time collectively. A pulsed automatic alarm system that provides time alert at hourly intervals was also incorporated. On testing the system was found to keep accurate time showing that design was successful.
