Abstract
In the present study, transients—rises and falls of the value of solar irradiance in the conditions of alternating Cumulus humilis and Cumulus fractus clouds—are studied to find their main characteristics, that is, the scope of their duration, magnitude, frequency, and shape. Of course, all these variables have a stochastic character and have been calculated using statistical analysis of ten automatic recordings. The results of the study characterize these clouds and show the degree of problems in generating PV electricity.
