The value of current source is calculate on variable IL (current generate) on equ3 based on equation 9, the value of current saturation on diode is calculate on variable I0 on equ3 based on equation 10, the value of resistor series and parallel its calculate manually and indicate on eqn3. The equivalent circuit is formed by following components: current source ( dc current source on source library), diode ( diode on non linear components library) and resistors ( resistor on lumped components library). Therefore, in Section 4 are calculated parameters using data from the photovoltaic cell indicated in datasheets, for equivalent circuit on figure 1c.įinal result of the simulation Qucs photovoltaic cell The problem is the parameter values of circuit components. Then, this circuit has a simple and accurate model to simulate a photovoltaic cell. The circuit of figure 1c is the more commonly used, although in several simulations simplifies the parallel resistance value with a high value, using the series resistance to include effect of fill factor, gets a similar circuit of figure 1d and used Rp to avoid problem with simulation. Other models include two diodes as in figure 1d, and. There are several circuits that include resistors for real effects of a photovoltaic cell, for example, figure 1b includes a resistor in series,, figure 1c includes parallel and series resistance, and.

The equivalent circuit of an ideal cell is formed by a current source in parallel with a diode ( figure 1a). Then, can be use PV module study PV grid connection and energy production prediction.Ģ. The model PV module can use to study mismatch effects due to different electrical characteristics of PV cells and the use of pass diode to reduce loss due to partial shadows. The model of PV cell can be used to simulate a PV module, because PV module is an association of cells in series and parallel. Also, can be used to test circuit with photovoltaic solar cell as power supply, in applications such as: micropower systems for harvesting energy, stand alone PV system for control battery charge. Further, can be used an attractive presentation to the student with a real representation of PV cell. This model can be used for training in photovoltaic solar energy, using: subcircuits, curves, tables and equations.

QUCS is a multiplatform application that runs on Windows and Linux, this software is available in Linux distributions for electronics. Additionally, you can use equations to define the model of photovoltaic cell and represent the characteristic curves on the same page. QUCS uses a generic diode for adjust the current and voltage curve (IV curve) at photovoltaic cell.

Free software used is Quite Universal Circuit Simulator ( QUCS).

The model presented is based on an equivalent circuit implemented in free software. There are numerous studies that develop the mathematical modeling of photovoltaic cells and verified by software, for example or.
