Development and Advantages of Renewable Energy Hybrid Systems (REHS)

Abstract

Solar power is a demand of our planet in coming days due to the depletion of non-renewable sources of energy. The renewable sources of energy are responsible for 80 % of world’s power and we all are directly dependent on non-renewable source which will only last in coming decades. Due to increase in power demands new development in renewable sources of energy are going on due to which on commercial level solar cell achieved an efficiency of 15 – 20 % and improving day by day. At a panel inclination of 22 oC, the effect of panel temperature and relative humidity on photovoltaic are studied. A precision digital hygrometer and thermometer, and a digital clamp meter were used in the process. Results obtained show that the effect of relative humidity on current, voltage, power of single and 10 panels combined together. The results also show that voltage and current remain fairly stable between 15 % to 35 % relative humidity. Panel’s temperature also plays a significant role on performance after 55 ºC, the voltage started dropping in both cases. Output from the wind turbine has also been measured on a working condition day, and different readings have been recorded with an interval of 15 mins at different wind speeds. It works by converting the kinetic energy in the wind first into rotational kinetic energy in the turbine and then electrical energy that can be supplied. The output energy comes directly depend on speed of wind and the blades swept area. Renewable Energy Hybrid System (REHS) is a system that utilizes two sources or more of renewable energy. As an advantage, it will produce continuous source of energy and utilizing one source in the absence of other source(s). The aim of this study is to enhance the energy output of renewable energy system which is the wind turbine by incorporating solar panels.
