The SPC is the identity card of a photovoltaic module. In it contains the main technical features that define the performance of the module. Often it is a description of the module, its components, cells and the material that constitutes it.
concentrate on the technical characteristics.
usually shows the ratings, that is the power measured in terms standard set by international standards (Standard Test Conditions, STC). But perhaps the most important feature of all is the tolerance on power. What is the meaning of this switch? This indicates the manufacturer's warranty as to the reproducibility over the years, the performance of the module, as indicated in the technical, with a consistency that has
deviations, according to a range more or less wide.
A little 'complicated, right? We express the same idea in different ways. The higher the value of tolerance Power, the lower the reproducibility of the module performance over the years, because the greater the deviation of performance respect to the parameters specified in the technical and, consequently,
lower the quality of the module.
