Renewable energy becomes challenging field with the increasing of the energy demand in the world. For the last three Decades, copious researches have been done to make renewable energy (RE) more feasible. Shortage in fossil fuels and concerns over global warming due to greenhouse gases are some of the stimulating factors lead to rapid progress in alternatives and renewable energy (RE) research [1], [2]. RE sources are more sustainable due to their natural abundance and environmental friendly nature.
