Solar energy is an attractive alternative source of electricity. The solar cell is the basic unit of a solar power plant. The maintenance of such a system requires the immediate discovery of malfunctions of the solar cells/modules it comprises. The most simple, fast and non-destructive way of diagnosing faults on photovoltaic modules are techniques of thermographic analysis. The thermographic analysis techniques can be used for quick fault diagnosis, not only during the operation of photovoltaic module but also during the construction phase. In this thesis, various techniques used to detect faults during the manufacturing process of photovoltaic modules are initially studied. Then, a computer software is developed that accepts as input a thermal image of a photovoltaic module or array, which is installed in a power system, and identifies the corresponding malfunctioning solar cells, as well as the types of faults.
