In discussing solar energy, the solar savings fraction or solar fraction (f) is the amount of energy provided by the solar technology divided by the total energy required.

Solar radiation pressure is due to the Sun's radiation at closer distances, thus especially within the Solar System.

The gradual loss of flux intensity through a medium. For instance, dark glasses attenuate sunlight, lead attenuates X-rays, and water and air attenuate both light and sound at variable attenuation rates.

Solar radiation closely matches a black body radiator at about 5,800 K. As it passes through the atmosphere, sunlight is attenuated by scattering and absorption; the more atmosphere through which it passes, the greater the attenuation.

The solar power tower, also known as 'central tower' power plants or 'heliostat' power plants or power towers, is a type of solar furnace using a tower to receive the focused sunlight.

A body of saline water several metres deep with increasing salinity with depth.

Panels contructed of photovoltaic cells in order to capture sunlight energy and convert it into electricity.

A solar mirror contains a substrate with a reflective layer for reflecting the solar energy, and in most cases an interference layer.

A solar micro-inverter, or simply microinverter, is a plug-and-play device used in photovoltaics, that converts direct current generated by a single solar module to alternating current.

A solar map, in general, is a map of a city, state, country, or any piece of land that illustrates information about how much a certain piece of land, building, or home experiences a certain amount of sunlight.

A solar lamp also known as solar light or solar lantern, is a lighting system composed of a LED lamp, solar panels, battery, charge controller and there may also be an inverter.

Solar irradiance is the power per unit area received from the Sun in the form of electromagnetic radiation as measured in the wavelength range of the measuring instrument.

A type of electrical converter which converts the variable direct current output of a photovoltaic solar panel into a utility frequency alternating current that can be fed into a commercial electrical grid or used by a local, off-grid electrical network.

Solar insolation is made up of direct, diffuse, and reflected radiation.

Solar hybrid power systems are hybrid power systems that combine solar power from a photovoltaic system with another power generating energy source.

Solar hot water is water heated using only energy from the Sun.

Solar guerrilla (or the guerrilla solar movement) is a term originated by Home Power Magazine and is applied to someone who connects solar panels without permission or notification and uses monthly net metering without regard for law.

Solar gain is the increase in thermal energy of a space, object or structure as it absorbs incident solar radiation.

A concentrated solar power structure that is used to produce high temperatures for use in power generation.

A synthetic chemical fuel produced from solar energy. Solar fuels can be produced through photochemical, photobiological, thermochemical, and electrochemical reactions.
