A new method to simulate photovoltaic performance of crystalline silicon photovoltaic modules based on datasheet values


The new method is proposed to simulate photovoltaic performance.

The new method requires no iteration techniques and no additional mandatory information.

The new method requires only datasheet values.

The new method is fast, accurate and easy to employ on crystalline silicon based module.

The new method is developed especially for photovoltaic designers and small-scale users.


Determination of photovoltaic performance based on single diode model and various methods requires iterative techniques, additional mandatory information and users with a certain level of knowledge. Further, the most of reported methods suffer from lack of details that make them non-repeatable. In this study, a new method based on single diode model is presented. This new method utilizes a new empirical relation that allows calculating the initial value of series resistance and thus extracting the reference model parameters solely from datasheet values provided by manufacturers. Validity of the new empirical relation has been tested through examining the 50 commercially available crystalline (poly and mono) silicon based photovoltaic modules. Simulation accuracy of the new method was tested for using experimental data from back contact mono crystalline silicon photovoltaic module, deployed outdoor and for published current-voltage curves of poly crystalline silicon photovoltaic module. The new method was compared also with other similar methods. The new method that is accurate and easy to employ requires no iterative techniques, no additional mandatory information and no users having special knowledge but only datasheet values given in technical catalogue of photovoltaic modules as simulating photovoltaic performance.

Graphical abstract

In this paper, a new method is presented to compute single diode model parameters that described the I-V curve and the photovoltaic performance. Using no additional information of I-V data, iteration techniques and users with a certain level of knowledge are main advantages of the proposed method. The new method will enable researchers, photovoltaic designers and small-scale users to simulate the real time performance of crystalline silicon based photovoltaic modules in most straightforward way.
