The cell area is one of the important factors that affect the output power developed by the cell. The value of the output power can be determined for a given input power in (W/m2), cell’s conversion efficiency in (%), and area of the cell in (m2). The solar cell efficiency is given under STC and the input power (PIN) is taken as 1000 W/m2.
Electric power is the product of the voltage across a device and the current through that device. Engineers use the theoretical power to characterize a solar cell. The power provided by the sun per unit area, known as solar intensity, is approximately 1,000 Watts per meter squared.
A solar cell can also be characterised by its maximum power point, when the product Vmp × Imp is at its maximum value. The maximum power output of a cell is graphically given by the largest rectangle that can be fitted under the I-V curve. That is, ̈ ̈ 1 ̧ ̧
The solar cell efficiency is given under STC and the input power (PIN) is taken as 1000 W/m2. Thus, by using the formula given below we can determine the output power generated for different efficiencies. PM = (PIN × Area) × ƞ
The power of a solar cell is the product of the voltage across the solar cell times the current through the solar cell. Here’s how to calculate the power the solar cell delivers to the motor: The maximum theoretical power from our solar cell, Pmax, is the product of the Voc and Isc.
The maximum current that a solar cell can produce occurs when a wire is connected across the terminals. This is called the short-circuit current, or Isc. Like a wire, an ammeter has very low resistance, so will register a measurement similar to a short circuit. Note the Isc through the solar cell.
