4. Passive solar building design - Wikipedia

   en.wikipedia.org/wiki/Passive_solar_building_design

   In a thermal storage wall system, often called a Trombe wall, a massive wall is located directly behind south-facing glass, which absorbs solar energy and releases it selectively towards the building interior at night. The wall can be constructed of cast-in-place concrete, brick, adobe, stone, or solid (or filled) concrete masonry units.

5. Photovoltaic mounting system - Wikipedia

   en.wikipedia.org/wiki/Photovoltaic_mounting_system

   A solar cell performs the best (most energy per unit time) when its surface is perpendicular to the sun's rays, which change continuously over the course of the day and season (see: Sun path). It is a common practice to tilt a fixed PV module (without solar tracker ) at the same angle as the latitude of array's location to maximize the annual ...

6. Sun-synchronous orbit - Wikipedia

   en.wikipedia.org/wiki/Sun-synchronous_orbit

   Special cases of the Sun-synchronous orbit are the noon/midnight orbit, where the local mean solar time of passage for equatorial latitudes is around noon or midnight, and the dawn/dusk orbit, where the local mean solar time of passage for equatorial latitudes is around sunrise or sunset, so that the satellite rides the terminator between day ...

7. Solarwall - Wikipedia

   en.wikipedia.org/wiki/SolarWall

   The SolarWall technology can also be installed as a hybrid solar system that generates both heat and electricity from the same surface area. By combining photovoltaics with the air heating technology, the heat produced by the solar panels is removed and drawn into the collector, helping to cool the solar panels and preheat the building's ...
