temperature of 25 ☌ and radiation of 1000 W/m 2. The PV module parameters are mentioned by the manufacturers under the Standard Test Condition (STC) i.e. Then the total current producing capacity of the cell will be 2 A × 5 = 10 A. For example, if a cell has a current producing capacity of 2 A and 5 such solar cells are connected in parallel.

Unlike the series connection, the total voltage of the string in parallel connection remains unchanged. The anode terminal of one cell is connected to the anode terminal of the next cell and similarly, the cathode terminal is connected to the cathode terminal of the next cell as shown in figure 2. Similarly, when the cells are connected in parallel the current of the individual cells is added. It is important to note that when the cells are connected in series the voltage gets added while the current remains the same. If 40 cells of 0.6 V are connected in series than the total voltage would be 0.6 V × 40 = 24 Volts.
#SOLAR CELL EFFICIENCY CALCULATION PC1D HOW TO#
When we connect N-number of solar cells in series then we get two terminals and the voltage across these two terminals is the sum of the voltages of the cells connected in series. The negative terminal of one cell is connected to the positive terminal of the other cell as shown in figure below. To increase the potential for the required power N-number of cells are connected in series. anode is the positive terminal and cathode is the negative terminal). When solar radiation falls on a single solar cell potential is produced across it two terminals anode and the cathode (i.e. These PV modules make it possible to supply larger demand than what a single cell could supply. Such a connection and arrangement of solar cells are called PV modules. So, to meet these high demands solar cells are arranged and electrically connected. Thus, a single PV cell is not capable of such high demand. In the case of grid-connected and industrial power plants, we require power in the range of Mega-watts or even Giga-watts.
A single solar cell cannot produce enough power to fulfill such a load demand, it can hardly produce power in a range from 0.1 to 3 watts depending on the cell area.
The power required by our daily loads range in several watts or sometimes in kilo-Watts.
