Energy requirement is increasing rapidly day by day due to its numerous applications. One of the commonly used methods to obtain electrical energy is from a solar photovoltaic system. A solar photovoltaic system consists of solar panels, batteries, charge controller and inverter. These solar panels consist of solar cells which absorb the radiant solar energy coming from sun and convert into useful electrical energy as output. Loss in the performance of solar panels is one of the significant problems with solar panels because they operate in open environmental conditions. Dust, depositions (dirt, cement deposits and bird droppings), shading effects are some of the important environmental factors which directly reduce the performance of solar panels and are impossible to neglect whenever performance parameters are to be studied. The dust, deposition and shade can be seen physically on the surface of solar panels but effects and faults caused by rise in temperature due to these factors are not be visualized by normal physical observation. The temperature rise causes heating and loss in power generation in solar panels and may result in damage, burning of solar panel or a big fault. The battery and inverters of solar photovoltaic system need to be monitored carefully for a satisfactory operation. A thermal imaging camera works on the principle of thermography is used to capture the heat emitted by the heated object. This research work shows a brief study on analyzing the temperature of different components of grid connected solar photovoltaic system with image processing by acquiring thermal images. It shows the temperature variation in the hot regions of dirt and deposits (bird droppings & cement deposits) on the surface of solar panels, solar batteries and inverters with the help of 3D temperature and contour plots. The analysis is performed with MATLAB digital image processing.
