  2. Rooftop solar power - Wikipedia

    en.wikipedia.org/wiki/Rooftop_solar_power

    An electrical power system containing a 10% contribution from PV stations would require a 2.5% increase in load-frequency control (LFC) capacity over a conventional system [jargon] —an issue which may be countered by using synchronverters in the DC/AC-circuit of the PV system. The break-even cost for PV power generation was in 1996 found to ...

  3. Building-integrated photovoltaics - Wikipedia

    en.wikipedia.org/wiki/Building-integrated...

    Because BIPV systems generate on-site power and are integrated into the building envelope, the system’s output power and thermal properties are the two primary performance indicators. Conventional BIPV systems have a lower heat dissipation capability than rack-mounted PV, which results in BIPV modules experiencing higher operating temperatures.

  4. Reflective surfaces (climate engineering) - Wikipedia

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

    The albedo of several types of roofs (lower values means higher temperatures). Reflective surfaces, or ground-based albedo modification (GBAM), is a solar radiation management method of enhancing Earth's albedo (the ability to reflect the visible, infrared, and ultraviolet wavelengths of the Sun, reducing heat transfer to the surface).

  5. Passive solar building design - Wikipedia

    en.wikipedia.org/wiki/Passive_solar_building_design

    These systems require good drainage systems, movable insulation, and an enhanced structural system to support a 35 to 70 lb/ft 2 (1.7 to 3.3 kN/m 2) dead load. With the angles of incidence of sunlight during the day, roof ponds are only effective for heating at lower and mid-latitudes, in hot to temperate climates.

  6. External floating roof tank - Wikipedia

    en.wikipedia.org/wiki/External_floating_roof_tank

    There is a rim seal system between the tank shell and roof to reduce rim evaporation. The roof has support legs hanging down into the liquid. At low liquid levels the roof eventually lands and a vapor space forms between the liquid surface and the roof, similar to a fixed roof tank. The support legs are usually retractable to increase the ...

  7. Solar heat collector and radiator for building roof - Wikipedia

    en.wikipedia.org/wiki/Solar_heat_collector_and...

    It was built to be used in conjunction with solar energy and uses a system of air circulation for increased efficiency. [1] A solar heat collector, or solar thermal collector , is used today to capture solar radiation through electromagnetic radiation with the use of solar hot water panels , solar parabolic troughs , or solar towers .

  8. Membrane roofing - Wikipedia

    en.wikipedia.org/wiki/Membrane_roofing

    Membrane roofing is a type of roofing system for buildings, RVs, ponds, and, in some cases, tanks. It is used to create a watertight covering to protect the interior of a building. It is used to create a watertight covering to protect the interior of a building.

  9. Retractable roof - Wikipedia

    en.wikipedia.org/wiki/Retractable_roof

    A retractable roof is a roof system designed to roll back the roof of a structure so that the interior of the facility is open to the outdoors. [1] Retractable roofs are sometimes referred to as operable roofs or retractable skylights. The term operable skylight, while quite similar, refers to a skylight that opens on a hinge, rather than on a ...
