“…This ideal model is completed with resistors to represent the losses and sometimes with additional diodes that takes into account other phenomena [10,11]. The most popular circuit equivalent to a solar cell/panel is shown in Figure 1, it includes a current source, one diode and two resistors: one in series and one in parallel [12][13][14][15][16][17][18][19]. Each element included in the equivalent circuit implies one parameter that has to be determined (two in the case of the diode whose behavior is represented by the Shockley equation [20]).…”

Due to the high dependence of photovoltaic energy efficiency on environmental conditions (temperature, irradiation...), it is quite important to perform some analysis focusing on the characteristics of photovoltaic devices in order to optimize energy production, even for small-scale users. The use of equivalent circuits is the preferred option to analyze solar cells/panels performance. However, the aforementioned small-scale users rarely have the equipment or expertise to perform large testing/calculation campaigns, the only information available for them being the manufacturer datasheet. The solution to this problem is the development of new and simple methods to define equivalent circuits able to reproduce the behavior of the panel for any working condition, from a very small amount of information. In the present work a direct and completely explicit method to extract solar cell parameters from the manufacturer datasheet is presented and tested. This method is based on analytical formulation which includes the use of the Lambert W-function to turn the series resistor equation explicit. The presented method is used to analyze commercial solar panel performance (i.e., the current-voltage-I-V-curve) at different levels OPEN ACCESSEnergies 2014, 7 4099 of irradiation and temperature. The analysis performed is based only on the information included in the manufacturer's datasheet.

“…[23] three methods for extracting the parameters of a solar cell are discussed. One method, based on Lambert W-function, has been proposed by authors while the other two methods have been proposed in [24,25]. The models were tested on a single crystalline solar cell.…”
