Photo Voltaic (PV) Cell Characteristics Design Using M.File In Matlab

Abstract

Solar energy is an emergent trend suitable for power production in both industrial and household appliances. The distributed renewable resource like solar energy is projected to act as a major responsibility in the forthcoming smart grid applications and technology. For the generation of electricity from solar power, it is essential to analyze the performance characteristics of the solar Photo Voltaic (PV) module, for instance, the power output of a PV panel and the prominent conversion efficiency. The performance of the electrical characterisation of a Photo Voltaic (solar) cells or module delivers the bond among the generated current and voltage on a typical solar PV cell which is termed as a V-I characteristic curve of solar cells. In this paper, a single diode correspondent circuit has been considered to inspect Voltage (V-I) and Power (P-V) characteristics for different insolation levels of a typical 100 W polycrystalline solar PV module. In order to validate the graphical depiction of the solar cell or module operation, M.file in MATLAB software was used. The generated characteristic curves summarise the connection between the current (I) and voltage (V) at the existing state of temperature with different irradiance. The obtained Power-Voltage (P-V) characterisation grant the essential information for building a solar electric power system to drive close up to its maximum peak powerpoint while feasible. The resulted graphs reveal that while considering the single diode model, the level of insolation varies with series resistance and by the generation of photo-current which in turn delivers the rapport of efficiency of solar cells. The proposed system is the initial step to learn a hybrid power system where some other renewable sources can be combined along with a solar power generation system.
