SRML Glossary — "N" Special thanks to NREL We'd like to thank the National Renewable Energy Laboratory for making available to us their glossary, which is the basis of ours. We've edited and reformatted it, and linked it to our Web pages, and we'll continue to add our own specialized terms, illustrations, and examples. Please note that the Solar Radiation Monitoring Laboratory takes full responsibility for any inaccuracies that may occur.

| A Normal
Incident Pyrheliometer,
used to determine the amount of solar irradiance emitted from the direction
of the sun. Below is a picture of two NIPs (silver) mounted on a sun-following
tracker (white) at the Solar
Radiation Research Laboratory. These thermopile-based
radiometers have a uniform spectral response
from 280 nm to 2800 nm and a 5.7° field of view.

There is no formal definition for this term. Typical usage defines it as any
energy source that is used faster than it is replenished. Standard examples are
petroleum products, natural gas, coal, and fissionable materials; the replenishment rates
of these energy sources are immensely slow, making it likely that they will become
depleted at some time.

| Radiation
striking a surface that is facing the sun. Mathematically, the word normal
is the vector (direction) that is perpendicular to a surface, and the direction
of a normal radiation source is perpendicular to a radiation
source. Global (total) normal solar irradiance is all radiation that
strikes a flat surface that faces the sun, while direct
normal solar irradiance excludes all radiation that does not come from
the direction of the sun in the sky.

in developing technologies and procedures for using renewable
energy sources.

The 1961-1990/ 1998-2015
National Solar Radiation Data Base, which supplies hourly
solar and meteorological data from 239 locations for 1961-1990 and satellite derived data from across the United States and its territories from 1998-2015.
