Abstract

This paper suggests a measurable parameter, the so-called Shading Tolerability (ST), to be added on PV modules datasheet. Using this parameter, PV modules can be compared and classified regarding the ability to oppose shading effects. The parameter is extracted based on mathematical and probability analysis, then measured using a Large Area Steady State Solar (LASSS) simulator. Outdoor measurements proved a correlation between ST and Performance Ratio (PR) of PV modules. ST was also found to be independent of the ambient temperature, which indicates that it is a characteristic parameter of a PV module. Finally, a selection map for PV module installation at different climate conditions based on ST and temperature coefficient for maximum power (\gamma)is presented.
