Effect of Environmental Parameters on Solar PV Performance with MPPT Techniques on Induction Motor Driven Water Pumping System
A photovoltaic cell produces electrical energy directly from visible light but their efficiency is fairly low and hence is expensive as compared to other available energy resources. Various factors affect pv system efficiency. This paper presents the important environmental factors which affect working of pv system by using MPPT techniques .These affects are solar Irradiation, temperature, humidity and wind speed . The variation of these factors at different condition has been studied to improve working of MPPT techniques for more reliable applications. In India there is a huge demand of energy due to various reasons like industrial development and increasing population. The main drawback in replacing conventional energy sources with new and more environmentally friendly alternative sources such as solar and wind energy, is how to capture them for maximum energy and how to deliver the maximum power at a minimum cost for a given load. The output power of photovoltaic cells or solar panels has nonlinear characteristics which are affected by temperature, light intensity and other environmental conditions and hence it is necessary to study them and rectify them for maximum and output.. To assess the overall performance with varying weather conditions, a PV model based on the Shockley diode equation has been used to predict the electrical characteristics of the cell with regard to changes in the environmental conditions of irradiation, temperature, humidity and wind speed.
