Concentrated Solar Power Overview

Introduction to Concentrated Solar Power

Concentrated Solar Power (CSP) is a technology that harnesses the power of sunlight to generate electricity. It uses mirrors or lenses to concentrate sunlight onto a receiver, which converts the solar energy into heat. The heat is then used to drive a steam turbine or heat engine, producing electricity. CSP systems offer a renewable and sustainable approach to large-scale power generation.
