Definitions

- Solar energy

energy derived from the sun in the form of solar radiation.

- Energy

the capacity for vigorous activity; available power.

- Light

something that makes things visible or affords illumination.

- Heat

the state of a body perceived as having or generating a relatively high degree of warmth.

- Sun

the star that is the central body of the earth's solar system, around which the planets revolve and from which they receive light and heat: its mean distance from the earth is about 93 million miles (150 million km), its diameter about 864,000 miles (1.4 million km), and its mass about 330,000 times that of the earth; its period of surface rotation is about 25 days at its equator but longer at higher latitudes.


 

- Photovoltaics

a field of semiconductor technology involving the direct conversion

of electromagnetic radiation as sunlight, into electricity.


 

- Thermal

Also thermic. of, relating to, or caused by heat or temperature.

- Solar  architecture

an architectural approach that takes in account the Sun to harness clean and renewable solar power.


 

- Molten salt power plants

Molten salt is used as a heat transfer fluid (HTF) and thermal energy storage (TES) in solar power plants.


 

- Artificial photosynthesis

a chemical process that biomimics the natural process of photosynthesis to convert sunlight, water, and carbon dioxide into carbohydrates and oxygen.

- Grid

Electricity.

  1. a metallic framework employed in a storage cell or battery for conducting the electric current and supporting the active material.

  2. a system of electrical distribution serving a large area, especially by means of high-tension lines.


 

- Grid tied

A grid-tied electrical system, also called tied to grid or grid tie system, is a semi-autonomous electrical generation or grid energy storage system which links to the mains to feed excess capacity back to the local mains electrical grid. When insufficient electricity is available, electricity drawn from the mains grid can make up the shortfall.


 

- Off-Grid

Off-the-grid or off-grid is a characteristic of buildings and a lifestyle designed in an independent manner without reliance on one or more public utilities. The term "off-the-grid" traditionally refers to not being connected to the electrical grid, but can also include other utilities like water, gas, and sewer systems, and can scale from residential homes to small communities.

- Watt

the standard unit of power in the International System of Units (SI), equivalent to one joule per second and equal to the power in a circuit in which a current of one ampere flows across a potential difference of one volt.

- Volt

the standard unit of potential difference and electromotive force in the International System of Units (SI), formally defined to be the difference of electric potential between two points of a conductor carrying a constant current of one ampere, when the power dissipated between these points is equal to one watt.

- Wind turbine

a turbine powered by the wind.


 

- Generator

a machine that converts one form of energy into another, especially mechanical energy into electrical energy, as a dynamo, or electrical energy into sound, as an acoustic generator.


 

- Inverter

Electricity. a device that converts direct current into alternating current.


 

- Battery

Also called galvanic battery, voltaic battery. Electricity. a combination of two or more cells electrically connected to work together to produce electric energy.


 

- AC current

Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC) which flows only in one direction.


 

- Semiautonomous

partially self-governing.


 

- Mains electricity

Mains electricity (Commonwealth English), also known by the American English terms utility power, power grid, domestic power, and wall power, or in some parts of Canada as hydro, is a general-purpose alternating-current (AC) electric power supply. It is the form of electrical power that is delivered to homes and businesses through the electric grid in many parts of the world.


 

- Solar thermal collector

A solar thermal collector collects heat by absorbing sunlight. The term "solar collector" commonly refers to a device for solar hot water heating, but may refer to large power generating installations such as solar parabolic troughs and solar towers or non water heating devices such as solar air heaters.

- Heat pump

a device that uses a compressible refrigerant to transfer heat from one body, as the ground, air, or water, to another body, as a building, with the process being reversible.


 

- Electric vehicle

An electric vehicle (EV) is a vehicle that uses one or more electric motors for propulsion.

- Recycle

to treat or process (used or waste materials) so as to make suitable for reuse.


 

- Pellet

a small, rounded or spherical body.


 

- Pellet stove

burns compressed wood or biomass pellets to create a source of heat for residential and sometimes industrial spaces.
