A part of the global solar irradiance G incident on the PV module front surface is converted into electric power [P.sub.el] depending on the instantaneous efficiency [[eta].sub.PV] of the PV module.
More recently, however, these operating reserves are being appropriately managed with accurate solar forecasts, as energy costs can be strategically minimized with knowledge of the short- and long-term variations in solar irradiance (Curtright and Apt 2008).
During the test, while measuring the characteristics I-V and P-V, the solar irradiance was also simultaneously measured alongside.
This comprehensive expansion work, based on various studies [21-23], considers nine design properties (i.e., mass sizing, aerodynamics, performance, stability and control, mission profile, solar irradiance, electric propulsion, sensitivity studies, and trend analysis) to improve the current design model.
In the system, the PV array transforms the solar irradiance into electrical power, and then this power is boosted up by Maximum Power Point Tracker.
Based on the above analysis, it is noted that when the solar irradiance increases, both the voltage and the current are increased.
The change in the output of a PV module is resulting from changes in temperature and solar irradiance. To maximize the efficiency of the solar cell, it is important to extract the maximum power output.
The clear-sky calculations reported in this work utilize a one-dimensional model which solves the radiative transfer equations for the downward scattered solar irradiance incident on the ground as a function of wavelength.
There are a number of sources for energy harvesting, for example, solar irradiance, wind, thermoelectric, piezoelectric, and vibration [5,6].
Figure 5 shows an increase in the PV array output power due to the increase in the solar irradiance. Figure 6 shows V-I curves for the PV array.
