MULTIFUNCTIONAL AUTOMATED SYSTEM FOR MONITORING PERFORMANCE OF SOLAR PV PANEL

Abstract

The utilization of sun energy into electrical or thermal energy is possible only through the help of panels. Solar panel is now widely used for a variety of industrial and domestic applications. A photovoltaic panel converts the sun’s radiation to electricity. It is often necessary to monitor health of a solar panel. But it is very difficult to measure the solar parameters manually as every time we need to go on the terrace and measure them using the multimeter. We have implemented the solar panel parameter measurement system. This project helps us in getting those parameters directly on Mobile through GSM and reduces human efforts. Dust will effect on the output parameter of solar panel. This system automatically cleans the dust on the Solar panel. Bidirectional solar panel tracks the sun to harness maximum power. Also this system helps us for detecting any failure in the system as we will come to know within short time due to remotely acquired parameters. This system automatically displays the various parameters of solar panel such as voltage, current, power, sun irradiance and dust level. For this we are using the PIC18F4520 controller for controlling I/O blocks like relays, motors, display, GSM, different sensors like(temperature sensor, dust sensor, light sensor) There is also the voltage divider circuitry along with the controller. We have driven the two loads at the output of system using the backup battery which will be charged by solar panel.
