Simulation of a photovoltaic solar module for the study of the effects of random changes of solar radiation

The present work is based on the simulation of the interconnection of 36 solar cells in a photovoltaic solar module (MS), of the Solar Shell brand, model Shell Power Max 85-P, by means of a mathematical simulator MATLAB, which offers swiftness and easiness of use. Relating the percentage of shade in given conditions of radiation to the point of maximum transference of power is intended, in order to be able to analyze the effects of random changes in solar radiation, on the production of energy, in outdoor conditions. The simulator provides the parameters of an open circuit tension (Voc)), the short circuit current (Isc), the maximum power (Pmax), and the characteristic curves of the solar module, depending on the shade effect that can hover on it, enabling the random study of changes of solar energy, in energy production. The experimental segment for attestation, as well as some of the trials carried out in different conditions of solar radiation are shown.
