Modelling and simulation of an automatic solar module characteristics data acquisition system

This paper is devoted to the design and simulation of an automatic data acquisition system of solar module characteristics. The system is essentially composed of three parts. The first part is devoted to the acquisition of the electrical parameters of the solar module (Current, Voltage and Power) in automatic ways using an automatic variable load. The second part is focused on devices which measure the ambient temperature and solar irradiation. In the last part, we study the design of an acquisition interface and a database for data saving. The results of simulations validate the correct operation of the measuring bench.
