  2. Solar energy - Wikipedia

    en.wikipedia.org/wiki/Solar_energy

    Solar energy is the radiant energy from the Sun's light and heat, which can be harnessed using a range of technologies such as solar electricity, solar thermal energy (including solar water heating) and solar architecture.

  3. Solar thermal collector - Wikipedia

    en.wikipedia.org/wiki/Solar_thermal_collector

    Solar air heating is a solar thermal technology in which the energy from the sun, solar insolation, is captured by an absorbing medium and used to heat air. Solar air heating is a renewable energy heating technology used to heat or condition air for buildings or process heat applications.

  4. Reflective surfaces (climate engineering) - Wikipedia

    en.wikipedia.org/wiki/Reflective_surfaces...

    A perfect roof would absorb no heat in the summer and lose no heat in the winter. To do this it would need a very high SRI to eliminate all radiative heat gains in summer and losses in winter. High SRI roofs act as a radiant barrier, providing a thermos-bottle effect. High emissivity cool roofs carry a climate penalty due to winter radiative ...

  5. 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

  6. Thermophotovoltaic energy conversion - Wikipedia

    en.wikipedia.org/wiki/Thermophotovoltaic_energy...

    Thermophotovoltaic (TPV) energy conversion is a direct conversion process from heat to electricity via photons.A basic thermophotovoltaic system consists of a hot object emitting thermal radiation and a photovoltaic cell similar to a solar cell but tuned to the spectrum being emitted from the hot object.

  7. The Biggest Draw of Solar Panels Isn’t Their Energy Bill Savings

    Solar panels absorb the sun's rays and turn the solar cells into functional energy. It's the future—just ask the Scott Brothers . So why don't you see more solar panels in your neighborhood?
