The performance analysis of a PV module or PV system is based on the I-V characterization of these components in dependence of several parameters like solar irradiance, module operating temperature, solar spectrum, solar angle-ofincidence, ambient temperature, wind speed, humidity. Several I-V curve tracers for single module or multi-tracers controller are available on the market for both spot I-V characterization or long term operative performance acquisition, but new and innovative test methods and analytical procedures are needed in order to assure high quality and reliability of measurements, mainly when the synchronism of the measurement of the I-V characteristic with other measured parameters (global and direct incident light, module temperature, sun spectrum, etc) is very relevant. In fact for PV-Concentrator modules the I-V curve needs to be acquired in very short time to avoid hot spot on the solar receivers , while the synchronism of measurement is very relevant to mitigate undesirable effects due to optical misalignments, thermal expansions and mechanical stresses usually change planarity of module surface and tracking reference plane. The proposed characterization tool PV-INTRASCAN® [3] allows at low cost, in very easy way by modular approach, to perform, in short time, complete campaigns of measurements for the acquisition of performance analysis of PV modules, PV-String and PV-Systems ranging from few Wp up to MWp for both PV flat or PV concentration systems.
