For electrical and mechanical connections, a solar power generation plant has many parts, namely arrays and modules of solar cells and means of controlling systems. Immense research is done in the area of power generation using solar energy at the practical level to evaluate the efficiency, lifespan, cost and durability of such power plants or even small‐scale grid systems. For the fulfilment of energy demand of people, use of hybrid power systems (Parida et al. 2011) is suggested where PV panels cannot generate regular electricity for consumption. In hybrid systems, PV systems are combined with hydro or wind turbines and sometimes with diesel or petrol‐driven generators for uninterrupted power supply. This hybrid system reduces the usage of fossil fuels.

For power generation using solar energy, different combinations are evaluated from time to time such as hybrid wind/PV or fuel cell power generation systems, wind/PV/battery system and wind/PV/fuel cell electrolyser system. In one of the studies researchers have developed a system by combining PV, wind and fuel cells to transfer maximum power to a fixed direct current voltage bus (El‐Shatter et al. 2006). In this study, fuzzy logic control was used to obtain maximum power tracking of PV and wind energy. Recently, this fuzzy scheme was used by different researchers to track the wind and PV energy so that maximum available solar and wind energy can be extracted.
