Description

	Radiation components over a horizontal surface: D is the Diffuse component of the radiation flow, and represents the part reflected by the atmosphere and the clouds, B is the Beam component, i.e. the part of the radiation which directly comes from the sun, G is the Global component corresponding to the sum of the two previous components.
	Radiation components over a horizontal surface: D: Diffuse B: Beam R: Reflected, i.e. the portion of the sun radiation reflected by the ground and visible by the tilted plane, G: Global
	Radiation components over a horizontal surface: D: Diffuse, B: Beam, R: Reflected, G: Global.

GHI	standard fixed-pv installations environment: for crops or forest to evaluate how much radiation they receive Hot water: for the black panels (hot water)
BNI	The plane is following the sun to maximize the amount of radiation received on the sensor. As a consequence, this parameter is more dedicated to concentrating solar thermal installations concentrating solar photovoltaic installations
GNI	If the radiation flux is not concentrated but the plane is still tracking the sun, the GNI must be considered.
