2. Skylight - Wikipedia

   en.wikipedia.org/wiki/Skylight

   Solar tubes, sun tunnels, or tubular skylights consist of a roof-mounted fixed unit skylight element, condensing sunlight, distributed by a light conveying optic conduit to a light diffusing element. [3] Being small in diameter, they can be used for daylighting smaller spaces such as hallways, and bounce light in darker corners of spaces. TDDs ...

   Skylights admit harsh direct overhead sunlight and glare [27] either horizontally (a flat roof) or pitched at the same angle as the roof slope. In some cases, horizontal skylights are used with reflectors to increase the intensity of solar radiation (and harsh glare), depending on the roof angle of incidence .

6. Building-integrated photovoltaics - Wikipedia

   Between the five categories, BIPV products can be applied in a variety of scenarios: pitched roofs, flat roofs, curved roofs, semi-transparent façades, skylights, shading systems, external walls, and curtain walls, with flat roofs and pitched roofs being the most ideal for solar energy capture. [8]

7. Photovoltaic mounting system - Wikipedia

   en.wikipedia.org/wiki/Photovoltaic_mounting_system

   Building-integrated photovoltaics (BIPV) are photovoltaic materials that are used to replace conventional building materials in parts of the building envelope such as the roof (tiles), skylights, or facades. They are increasingly being incorporated into the construction of new buildings as a principal or ancillary source of electrical power ...

8. Daylighting (architecture) - Wikipedia

Roof lanterns serve as both an architectural feature and a method of introducing natural light into a space, and are typically wooden or metal structures with a ...
