An algorithm to accurately calculate solar panel parameters
(Nanowerk News) Researchers have designed an algorithm that allows users to calculate online the parameters of a model that emulates the behaviour of a solar panel. The algorithm has made it possible to create the first website of these characteristics in the world.
Researchers from the University Institute for Research (CIO) of Alicante’s Universidad Miguel Hernández (UMH), Elche Javier Toledo, the Group of Industrial Electronics (IE-g) of the UMH José Manuel Blanes, and the Architectural and Computer Technologies Group of the UMH (GATOM), Vicente Galiano, have designed an algorithm that allows users to calculate online, on the website pvmodel.umh.es, the parameters of a model that emulates the behaviour of a solar panel.
The algorithm has made it possible to create the first website of these characteristics in the world by working completely independently, and is able to function with the figures of voltage and intensity of any solar panel.
The algorithm, which runs on the website, is explained in full in an article that UMH researchers have published in the international magazine IEE Transactions on Industrial Electronics (a magazine which has a 7,168 JCR impact factor, ranking first place in the categories of Automation & Control Systems and Instruments & Instrumentation). This algorithm obtains its results from a single-diode model, which has been studied for over 40 years for the optimum production of solar panels, among other uses.
Named “Two-Step Linear Least-Squares method” (TSLLS), the algorithm provides the best results to date in two case studies in this area of research as well as, on average, in over a million curves of a repository of the National Renewable Energy Laboratory (NREL) in the USA.
The website is free of charge for the time being for the scientific community and companies interested in obtaining the relevant parameters for their solar panels.
