The Concentrated Solar Thermal Industry is revolutionizing the renewable energy sector by offering a highly efficient method to generate electricity from solar energy. Unlike conventional solar photovoltaic (PV) systems that convert sunlight directly into electricity, concentrated solar thermal (CST) systems use mirrors or lenses to focus sunlight onto a receiver, generating high-temperature heat. This heat is then converted into electricity using turbines or stored for later use. As Per Market Research Future, the industry is witnessing substantial growth due to increasing demand for renewable energy, technological advancements, and global initiatives to reduce carbon emissions.
