Development of solar efficiency monitoring system by using GSM technology

Photovoltaic or PV for short, is a method that is unique and distinctive in harnessing the sun's energy. One of the results that should be taken into account in the use of solar panel is the efficiency of the solar panel itself, because efficiency refers to the amount of light of the whole module that turns it into electricity. The efficiency of the Solar panel will be lower if there is a distance between the cells and also because the glass cover and reflect the light from the sun is absorbed into the cells. Thus, it should be given particular attention because of the efficiency show exactly how much electricity will be generated from the solar panel. The purpose of this project is to develop monitoring system efficiency solar cells, where the system will notify the user via SMS. If the efficiency of solar cells falls below a certain level, the GSM will give a notification to the user. The project will be built using the Arduino Mega 2560 microcontroller, GSM as a way of communication between Arduino Mega and GSM. Two sensors will be used, humidity and light dependent resistor (LDR). This device will measure the efficiency solar panel, moisture and light on the circumstances surrounding. Throughout the paper, a technical description of the developed system, and analysis on the solar efficiency have been discussed.
