Abstract
This paper aims to give an overview of the solar tower technology and its consequences along with a new concept of mini solar towers using Fresnel lens. Fresnel lens are used to concentrate the solar radiation falling on the aperture to a particular point. It contributes to update the economic status and technical status of molten salt solar tower technology. It has aspired to explain the solar power tower with an overview of energy, renewable energy, solar energy, solar photovoltaic, solar thermal and Fresnel Lenses.
