  2. Nanofluids in solar collectors - Wikipedia

    en.wikipedia.org/wiki/Nanofluids_in_solar_collectors

    An ideal solar collector will absorb the concentrated solar radiation, convert partially that incident solar radiation into heat and transfer the heat to the heat transfer fluid. Higher the heat transfer rate to the fluid leads to higher outlet temperature and higher temperatues leads to improved conversion efficiency in the power cycle ...

  3. Solar thermal collector - Wikipedia

    en.wikipedia.org/wiki/Solar_thermal_collector

    The collector absorbs the incoming solar radiation, converting it into thermal energy. This thermal energy is then transferred to a heat transfer fluid circulating within the collector. [32] The heat transfer fluid can be air, water, oil, or a mixture including glycol (an antifreeze fluid), especially in forced circulation systems. [32]

  4. Solar energy - Wikipedia

    en.wikipedia.org/wiki/Solar_energy

    Heat pumps are designed to move thermal energy opposite to the direction of spontaneous heat flow by absorbing heat from a cold space and releasing it to a warmer one. A solar-assisted heat pump represents the integration of a heat pump and thermal solar panels in a single integrated system.

  5. 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 ...

  6. Selective surface - Wikipedia

    en.wikipedia.org/wiki/Selective_surface

    The surface absorbs sunlight nearly completely, and emits very little of the solar heat as thermal radiation. Ordinary black surfaces are also efficient absorbers, but they emit thermal radiation copiously. In solar thermal collectors, a selective surface or selective absorber is a

  7. Photovoltaics - Wikipedia

    en.wikipedia.org/wiki/Photovoltaics

    Usually solar panels are exposed to sunlight for longer than this in a given day, but the solar irradiance is less than 1000 W/m 2 for most of the day. A solar panel can produce more when the Sun is high in Earth's sky and produces less in cloudy conditions, or when the Sun is low in the sky. The Sun is lower in the sky in the winter.
