Abstract: Nowadays the non-renewable energy sources, their availability and consumptions have become the areas of concern due to people’s growing needs and utilizations. The current status of the society and environment is to find an energy source which should be an alternative for the depleting fuels and ecofriendly. Further to add to our worries are the harmful effects of these fuels. These have resulted in ending up with the choice of solar energy utilization. Sometimes the industries have to go for the design of economic hybrid systems. The remedies for the international issues like oil crisis, global warming, ozone depletion and harmful emissions are the applications of the renewable solar energy. The current work is about the investigation of different types of drying systems and solar dryers. The aim of the study is to design a heat exchanger system using solar energy for drying processes and enhancing their performances. Advanced nanotechnology applications like the utilization of the nanoparticles and fin profiles for heat transfer enhancements are found to be one of the areas of research and improvement in this field. Solar energy has been finding its hopeful and promising applications nowadays.
