The following are some important parameters in solar panel installations under standard test conditions (STC). These conditions include a cell temperature of 25°c, solar irradiation of 1000W/m 2, and atmospheric density of 1.5. Fig. 1 shows the power, current, and voltage curves.
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).
PV cell parameters are usually specified under standard test conditions (STC) at a total irradiance of 1 sun (1,000 W/m2), a temperature of 25°C and coefficient of air mass (AM) of 1.5. The AM is the path length of solar radiation relative to the path length at zenith at sea level. The AM at zenith at sea level is 1.
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).
The quality of materials is a crucial factor in the performance of solar panels. Panels made with higher quality photovoltaic cells tend to have better energy efficiency, resulting in higher electricity production per square metre.
The properties of a solar panel tell you the capacity of the module, its efficiency, and its suitability. In readymade panels, these properties are provided as ratings, and they vary from module to module. However, if you intend to build your own module, these properties would act as guidelines.
