A software platform has been developed in order to unify the different measurements obtained from different manufacturers. These measurements include the curve from voltage to the current of PV devices and several meteorological parameters such as global and direct irradiance, temperature level of the solar cells and spectral shape distribution of solar irradiance. The measurements are performed in an automated way by a stand-alone application that is able to communicate with a pair of multimeters and a bipolar power supply that are controlled in order to obtain the current–voltage pairs. In addition, several magnitudes, that can be configured by the user, such as irradiance, module temperature or wind speed, are incorporated to register the conditions of each measurement. Moreover, it is possible to attach to each curve the spectral distribution of the solar radiation at each moment. Independently of the source of the information, all these measurements are included in our own database. These data can be accessed through a public web site that can generate several graphics from the data.
