<p>The principle of the invention is to get the coordinates of this maximum maximorum point (MMP) of a solar panel composed of n paralleled strings in working conditions, what ever are the string temperatures, their ageing and their sun illumination. The processes are two: The first one is a mathematical process conducting to a rapid, accurate and reproducible result. The second method calls for a voltage sweep. The mathematical process comprises a first step of the identification of the 3 parameters defining the electrical characteristics of each string, a second one the knowledge of the analytical forms of the solar array characteristics, formula (2.14). And finally computation of the MPP of the solar array, which corresponds to the voltage which makes the first derivative of the power function equal to zero: formula (2.15).</p> |
