A Solar Photovoltaic Module is available in a range of 3 WP to 300 WP. But many times, we need powerin a range from kW to MW. To achieve such a large power, we need to connect N-number of modules in series and parallel. A String of PV Modules When N-number of PV modules are. .
Sometimes the system voltage required for a power plant is much higher than what a single PV module can produce. In such cases, N-number of PV modules is connected in series to deliver the required voltage level. This. .
Sometimes to increase the power of the solar PV system, instead of increasing the voltage by connecting modules in series the current is increased by connecting modules in parallel.. .
When we need to generate large power in a range of Giga-watts for large PV system plants we need to connect modules in series and parallel. In large PV plants first, the modules are. The number of cells to be connected in series depends on the voltage at maximum power point i.e. VM of the individual cell and the voltage drop that occurs due to an increase in the temperature of the cell above STC.
