The diagram illustrates the conversion of sunlight into electricity via semiconductors, highlighting the key elements: layers of silicon, metal contacts, anti-reflective coating, and the electric field created by the junction between n-type and p-type silicon. The solar cell diagram showcases the working mechanism of a photovoltaic (PV) cell.
The array’s direct current is approximately 1000 VDC. Fig. P20 – Diagram showing a photovoltaic array consisting of several groups An alternate solution to DC system is to closely link the inverter to the PV module, in that case the PV module become an AC power source.
Array: A group of panels that comprises the complete PV generating unit. This array is made up of 8 panels, consisting of 3 modules each, for a total of 24 modules in the array. If the PV system has more than one grouping of PV modules, we call each grouping a sub-array. The total of all the sub-arrays is then called the complete PV array.
The cell is a part of a “circuit” (Latin for ”go around”), where the same electrons just travel around the same path, getting energy from the sunlight and giving that energy to the load. Cell: The basic photovoltaic device that is the building block for PV modules. All modules contain cells.
The Solar Cell Array The array is composed of solar modules connected according to certain configuration to satisfy the voltage, the current, and the power requirement. If the array voltage is Va, the array current is Ia, and the array power is Pa, one can determine the number of the modules required and their circuit configuration.
Configuration of PV arrays depends on required rated voltage and current of a power plant. If Ns cells are connected in series and Np cells are connected in parallel then equation of Ipv can be expressed as:
