Data Monitoring System of Solar Module with Data Logger for Public Street Lighting Application

In satisfying the electrical energy needs of Public Street Lighting, recently the solar energy is one of the alternatives which are widely utilized. The solar energy which is collected by the solar module is converted and stored into a voltage source of electrical energy. In terms of maintenance process, if there are a large number devices of Public Street Lighting, the problem of efficiency arises. The maintenance becomes inefficient if the process has to be conducted one by one for each point and carried out for a time continuously. In this paper, one alternative method is proposed by using a data logger developed using an ATmega328 microcontroller on the solar module of Public Street Lighting. Here, data logger will record and store all data flows and voltages that work on the device. The data which are stored into SD Card storage every 1 minute will be easily accessed and monitored via a personal computer (PC). The performance result shows that the output voltage is influenced by the intensity of light received by the solar module. The output voltage is about 15 volt which corresponds to the received light intensity of 69.4%.
