Solar Energy

Solar energy schemes based on photovoltaic cells have attracted extensive interest in recent years due to their capabilities of clear and seemingly limitless generated energy. This chapter proposed a simple, cost effective and efficient system for solar photovoltaic applications. Solar energy is considered as an fastest growing renewable energy resource like wind energy for electricity generation. Solar energy is a free, clean abundant sun energy considered an inexhaustible source for electricity generation. The solar photovoltaic system is characterized by variable output power due to its operation dependency on solar irradiance and cell temperature. To maximize the energy generation potential of solar PV, a research effort is focused on solar cell manufacturing technology to increase its generation efficiency and explore advancements in power electronic devices for small and large scale deployment. The main aim is to find the unknown parameters of the nonlinear current–voltage (I-V) equations by adjusting the I-V curve at three remarkable points when the circuit is open (open circuit), when the circuit is delivering maximum power, and when it is short circuited. The data of these three studies are mentioned by all commercial PV module makers in their datasheets and with all these parameters of the adjusted I-V equation
