Typically, the I-V characteristics curve is drawn at one sun radiation (1000 W/m 2) however, variation in solar radiation value predominantly changes the current output from the solar panel and subsequently the power output. The output voltage from solar panel is highly dependent on the operating temperature of the solar cells.
The Solar IV (Current-Voltage) Curve is the characteristic curve of a solar cell, which is essential for understanding the performance of a solar cell. It is also used to determine important parameters such as the open-circuit voltage (Voc), the short-circuit current (Isc), the maximum power point voltage (Vmpp), and more.
Elements such as irradiation levels, ambient temperature, shading, soiling on the panels, and inherent resistances within the cell (shunt and series resistance) can all impact the curve’s configuration and, by extension, the cell’s efficiency. It’s crucial to distinguish between a solar IV curve and a solar power curve.
The most crucial of all is the maximum power point (MPP), where the product of current and voltage reaches its apex, indicating optimal power output. The maximum power point on a solar power curve is identified through a process that involves maximizing the product of current and voltage.
Solar PV cells convert sunlight into electricity, producing around 1 watt in full sunlight. Photovoltaic modules consist of interconnected cells, and their output characteristics are represented in an I-V curve. Parameters like open circuit voltage, short circuit current, and maximum power point are crucial for system design.
Figure 2: Power Curve for a Typical PV Cell Figure 3: I-V Characteristics as a Function of Irradiance PV cells are typically square, with sides ranging from about 10 mm (0.3937 inches) to 127 mm (5 inches) or more on a side. Typical efficiencies range from 14% to 18% for a monocrystalline silicon PV cell.
