2. Solar energy - Wikipedia

   en.wikipedia.org/wiki/Solar_energy

   Solar energy is the radiant energy from the Sun's light and heat, ... Socrates' Megaron House is a classic example of passive solar design. [74]

3. Outline of solar energy - Wikipedia

   en.wikipedia.org/wiki/Outline_of_solar_energy

   Active solar – technologies are employed to convert solar energy into another more useful form of energy (for example, to heat or electrical energy). Heliostat – a device that includes a mirror, usually a plane mirror, which turns so as to keep reflecting sunlight toward a predetermined target, compensating for the Sun's apparent motions in ...

4. Photovoltaic system - Wikipedia

   en.wikipedia.org/wiki/Photovoltaic_system

   A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics.It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and ...

5. Photovoltaics - Wikipedia

   en.wikipedia.org/wiki/Photovoltaics

   The efficiency of the solar cells used in a photovoltaic system, in combination with latitude and climate, determines the annual energy output of the system. For example, a solar panel with 20% efficiency and an area of 1 m 2 produces 200 kWh/yr at Standard Test Conditions if exposed to the Standard Test Condition solar irradiance value of 1000 ...

6. Renewable energy - Wikipedia

   en.wikipedia.org/wiki/Renewable_energy

   The two most important forms of renewable energy, solar and wind, are intermittent energy sources: they are not available constantly, resulting in lower capacity factors. In contrast, fossil fuel power plants, nuclear power plants and hydropower are usually able to produce precisely the amount of energy an electricity grid requires at a given ...

7. Solar cell - Wikipedia

   en.wikipedia.org/wiki/Solar_cell

   Application of solar cells as an alternative energy source for vehicular applications is a growing industry. Electric vehicles that operate off of solar energy and/or sunlight are commonly referred to as solar cars. [citation needed] These vehicles use solar panels to convert absorbed light into electrical energy that is then stored in batteries.
