Abstract
Three photo-voltaic commercial panels based on poly-crystal (two panels) and amorphous (one panel) solar cells are analyzed. The behavior of the panels under transients, arising due to instantaneous load changes, is investigated. Two types of transients are analyzed: an instantaneous short-circuiting and an instantaneous open-circuiting. It is observed that the solar cell panels behave differently under transients arising due to their short-circuiting and open-circuiting. The transients arising due to instantaneous short-circuiting from an open circuit condition have a character of damped oscillations for all analyzed solar cell panels. The transients arising due to instantaneous open-circuiting from a short circuit condition have a character of exponential growth for all analyzed solar cell panels. The processes developed under above transients are determined by the solar cell panel parameters only, therefore the results obtained cannot be explained by the currently used equivalent diagrams.
