“…For the conversion of sunlight into electricity, solar photovoltaic cells and panels are employed. The most trustworthy information on a solar cell's efficiency at transforming sunlight into electricity is provided by its IV properties [7]. The most practical and extensively used way of directly generating electricity from sunlight for solar energy production is photovoltaic (PV) power generation, which may be used in both home and business settings [8][9][10][11].…”

“…Controlling the current produced by the solar cells or modules between the zero-current point (Voc) and the shortcircuit point (Isc) is the basic notion underlying assessing the I-V curve [18,19]. The I-V curve of solar photovoltaic modules can be measured in many ways, such as with variable resistors, electronic loads, capacitive loads, bipolar power configurations, and four-quadrant power supplies [20,22].…”

The electrical performance of photovoltaic (PV) cells or arrays is greatly influenced by the ambient temperature and the solar radiation intensity (irradiation) as well. The effect of temperature and solar irradiance on the main characteristics of solar panels and photovoltaic modules is investigated in this paper. The primary parameters are identified and extracted using the capacitive load approach. These parameters are Short Circuit Current (Isc), Maximum Power Point Current (Impp), Open Circuit Voltage (Voc), Maximum Power Point Voltage (Vmpp), Maximum Power Point (Pmax), Fill factor (FF) and Efficiency (η). The PV cell used in this study is poly-crystal silicon. Its commercial name is Kyocera solar KC130GT. MATLAB Simulink is used to assess the capacitive load method in the investigation of I-V and P-V curves. These two curves are derived based on the effects of varying temperatures (30, 35, 40, and 45 o C) at a constant irradiance (1000 W/m 2 ) on the PV cell performance and the effect of varying irradiance (250, 500, 750, and 1000 W/m 2 ) at constant temperature (25 o C) as well. It is concluded that by increasing the irradiance at constant temperature, Isc and Voc are increasing. As a result, η increases from 13.9% at 250 W/m 2 to reach 14.7% at 1000 W/m 2 . In the case of increasing temperature at constant irradiance, η decreases from 13.5% at 30 o C to reach 12.8% at 45 o C. This is due to the large drop in Voc compared to the small increment in Isc.
