A solar power tower is a system that converts energy from the Sun - in the form of sunlight - into electricity that can be used by people by using a large scale solar setup. The setup includes an array of large, sun-tracking mirrors known as heliostats that focus sunlight on a receiver at the top of a tower. In this receiver, a fluid is heated and used to generate steam.
Solar thermal power generation is a technology that harnesses the sun''s energy to produce electricity. Unlike photovoltaic (PV) systems, which convert sunlight directly into electricity, solar thermal plants convert sunlight to heat using various mirror configurations. ...
