Study of Photovoltaic Systems Monitoring Methods

To maximize photovoltaic systems performance the monitoring of them is essential. There are several faults that produce energy losses in the system. When a fault happens the monitoring system has to detect it and give an indication about which is the component with the fault. For this, in most system a set of parameters are measured, usually four: current, voltage, temperature and irradiance. In some monitoring systems these measures are obtained for the whole plant whereas in others, the modules are measured one by one. In this work, a study of these methods is presented.
