Abstract: Solar energy is an important source of renewable energy. It is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as photovoltaic, solar heating, molten salt, solar thermal energy, solar architecture, power plants and artificial photosynthesis. We use the solar energy to heat the air for various applications such as food drying, air conditioning, preheating, etc.

Keywords: Solar energy, parabolic solar collectors, parabolic solar reflector.
