Outline of solar energy


The following outline is provided as an overview of and topical guide to solar energy:
Solar energy – radiant light and heat from the sun. It has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar energy technologies include solar heating, solar photovoltaics, solar thermal electricity and solar architecture, which can make considerable contributions to solving some of the most urgent problems that the world now faces.

Overview

Solar energy can be described as all of the following:
– the conversion of sunlight into electricity, either directly using photovoltaics, or indirectly using concentrated solar power.
– technology for harnessing solar energy for thermal energy.
– a system that uses mirrors or lenses to concentrate a large area of sunlight, or solar thermal energy, onto a small area. Electrical power is produced when the concentrated light is converted to heat, which drives a heat engine connected to an electrical power generator.
