Suppose, terminal voltage of a solar cell is 0.5 V under operating conditions (shown in Figure 4.3) and two such identical cells are connected in series, so the terminal voltage of string of two solar cells will be 0.5 + 0.5 = 1 V.
The power of a solar cell is the product of the voltage across the solar cell times the current through the solar cell. Here’s how to calculate the power the solar cell delivers to the motor: The maximum theoretical power from our solar cell, Pmax, is the product of the Voc and Isc.
The maximum voltage, on the other hand, is fixed by the material the solar cell is made of. Solar cells also have an internal resistance, which reduces the voltage available at the terminals when current flows. Electric power is the product of the voltage across a device and the current through that device.
EXAMPLE 4.11 A solar PV module’s maximum power output at 300 W/m2 and 700 W/m2 is 42 watt and 98 watt respectively. What will be the PV Wp rating of the module under STC. Assume the temperature of the cells module remain the same in both conditions.
Under STC the corresponding solar radiation is equal to 1000 W/m2 and the cell operating temperature is equal to 25oC. The solar cell parameters are as follows; Short circuit current is the maximum current produced by the solar cell, it is measured in ampere (A) or milli-ampere (mA).
Open Circuit Voltage: The voltage across the solar cell’s terminals when there is no load connected, typically around 0.5 to 0.6 volts.
