There are several terms associated with a solar panel and their ratings such as nominal voltage, the voltage at open circuit (Voc), the voltage at maximum power point (Vmp), open circuit current (Isc), current at maximum power (Imp), etc. All these parameters are crucial to know before purchasing or installation of solar panels.
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). As can be seen from table 1 and figure 2 that the open-circuit voltage is zero when the cell is producing maximum current (ISC = 0.65 A).
Most solar cells available in the market offer an efficiency of 17-19% and the highest efficiency of a commercial solar panel is about 23%. The fill factor (FF) denotes the efficiency of a solar cell. It is denoted by the ratio of maximum power point (MPP) to the product of short circuit current (Isc) and open circuit voltage (Voc).
The nominal power of the solar panel is measured under Standard Test Conditions (STC), i.e., at an irradiance of 1000W/m², cell temperature of 25°, and air mass of AM=1,5. These are standard test conditions. The actual performance of the solar panel would vary significantly compared to its performance in Lab conditions.
The most important characteristic of any solar panel is its power output and photovoltaic solar panels are available in a wide range of power outputs ranging from a few watts to more than 400 watts for the bigger panels and/or modules.
The article covers the key specifications of solar panels, including power output, efficiency, voltage, current, and temperature coefficient, as presented in solar panel datasheets, and explains how these factors influence their performance and suitability for various applications.
