Sun Direct is a joint venture between the Astro Group of Malaysia and the SUN Group of India. Sun Group entered into an MoU with the Astro group on 27 January 1997, when Aircel was not in existence. But, since the government of India did not allow the use of KU band transponders for DTH services, the project was put on hold, the firm said in a ...
Using this algorithm, if the month in question is notated month 0, a weighted average is formed of months −6 to 6, where months −5 to 5 are given weightings of 1, and months −6 and 6 are given weightings of 0.5. Other smoothing formulas exist, and they usually give slightly different values for the amplitude and timings of the solar cycles.

When 1361 W/m 2 is arriving above the atmosphere (when the Sun is at the zenith in a cloudless sky), direct sun is about 1050 W/m 2, and global radiation on a horizontal surface at ground level is about 1120 W/m 2. [36] The latter figure includes radiation scattered or reemitted by the atmosphere and surroundings.
World map showing the areas of Earth receiving daylight around 13:00 UTC in April. Daylight is the combination of all direct and indirect sunlight during the daytime.This includes direct sunlight, diffuse sky radiation, and (often) both of these reflected by Earth and terrestrial objects, like landforms and buildings.
Sun path, sometimes also called day arc, refers to the daily (sunrise to sunset) and seasonal arc-like path that the Sun appears to follow across the sky as the Earth rotates and orbits the Sun. The Sun's path affects the length of daytime experienced and amount of daylight received along a certain latitude during a given season.
The shading coefficient (SC) is a measure of the radiative thermal performance of a glass unit (panel or window) in a building.It is defined as the ratio of solar radiation at a given wavelength and angle of incidence passing through a glass unit to the radiation that would pass through a reference window of frameless 3 millimetres (0.12 in) Clear Float Glass.

Greenhouse gas emissions per energy source. Solar power is one of the sources with the least greenhouse gas emissions. Part of the Senftenberg Solarpark, a solar photovoltaic power plant located on former open-pit mining areas close to the city of Senftenberg, in Eastern Germany. The 78 MW Phase 1 of the plant was completed within three months.
