Completely Free

We offer completely FREE to the scientific community and to the PV panels manufacturers a Website which provides: 1) the five parameters of the single-diode PV model just from a set of experimental I-V data; 2) all possible combinations of five parameters of the single-diode model from manufacturer's datasheet.

Scientific Methods

The parameters of the single-diode model can be computed with two methods: TSLLS or Reduced Form. By other hand, all possible combinations of five parameters from manufacturer's datasheet is obtained with a novel methodology developed in a recent paper. If anybody is interested, please contact us.

Best results

The parameters provided by the TSLLS and Reduced Form methods are the best ones obtained in the literature in the case studies considered in the corresponding papers. All possible combinations of five parameters from manufacturer's datasheet is a very new find. Comments and suggestions are very welcome. Please, contact us.

Input your I-V curve or your datasheet values

The TSLLS and Reduced Form methods work with experimental I-V data from almost any kind of PV panel in any environmental condition. The datasheet method just needs the well-known remarkable I-V curve points (open circuit, short circuit points and maximum power point). To be able to save your simulations and manage them whenever you want on our website, you can make an easy and free registration.
