The demand for energy is growing day by day due to industrial urbanization. Renewable energy sources such as solar photovoltaic, wind, biomass, small hydropower and others are widely being deployed to reduce fossil fuels consumption and pollution level in the environment. In recent times, the cost of energy generation from renewable energy sources mainly by solar and wind has reached the state of competitiveness to the conventional energy sources i.e., coal, oil and natural gases, in some places it is even cheaper than conventional energy. Generating and providing reliable, uninterruptible power supply is a highly challenging task. To overcome the challenges, multiple renewable energy sources with an optimum size needs to be integrated. Integrated energy systems have various advantages such as efficient resource management, increased energy production, proper load balancing, less operational and maintenance cost and less emission release to the environment. There is a way to combine the positives of both solar and wind power generating devices to offset the drawbacks that they individually have. It is interesting to note that solar and wind power naturally complement each other and hence the hybrid setup can generate more reliable power than having either a solar or wind based power separately. A solar-wind hybrid system helps to improve not only the combined efficiency but also the working performance of batteries as the charge and discharge cycles are more uniform improving its life, thus reducing the cost of the batteries. The main advantages of the hybrid system are an increased efficiency, more energy density (energy per sq. meter), best suitable for decentralized energy supply and low installation cost compared to solar and wind energy systems if they are installed separately. The hybrid concept is unique, seamlessly utilizing both solar and wind energy generation in one single unit.Solar-wind hybrid system has become an affordable and reliable source of energy in recent times. This Book aims to describe about solar-wind hybrid system, components and research aspects of hybrid system. This book is an outcome of our experience of conducting research activities on hybrid systems.
