V-I characteristic and PV characteristic of solar cell at nominal temperature and irradiance are evaluated by using simulink model shown in fig 2. Varying resistive load is connected at the output and output power is depends on the parameter value of load.
The output power of the PV cell is voltage times current, so there is no output power for a short-circuit condition because of VOUT or for an open-circuit condition because of IOUT = 0. Above the short-circuit point, the PV cell operates with a resistive load.
The results show that the proposed model presents good versatility and sensitivity, can quickly and accurately reflect the output characteristics of PV array under various complex irradiations, it can be used for modeling and simulation of large-scale PV power generation systems, proved foundation for the PV array optimal layout.
Other important characteristics include how the current varies as a function of the output voltage and as a function of light intensity or irradiance. The current-voltage (I-V) curve for a PV cell shows that the current is essentially constant over a range of output voltages for a specified amount of incident light energy.
The photovoltaic cell's power-voltage characteristic is non-linear. The maximum power point (MPP) must be constantly monitored to achieve the maximum performance power from the photovoltaic device. Solar cell implementations have been challenging in recent years.
The presence of the diode changes the path of the current, and also changes the circuit topology of PV array, which can affect the output power of PV array and produce multiple power extremes, and cause the traditional MPPT algorithm to fall into local extremes values.
Parameters of a Solar Cell and Characteristics of a PV Panel
Let''s take an example to understand the decrease in one of the parameters (i.e. voltage). A cell is having an output voltage of 0.9 V at STC. The operating temperature of the cell is 50 o C.
