SRML Glossary — "K" 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.

 The temperature
unit based on the theoretical minimum temperature, used in many physical
calculations. The relationship between Kelvin and Celsius
is
K = C + 273.16  
 The ratio
between diffuse sky radiation and
extraterrestrial radiation,
used as a normalization of the diffuse sky radiation because K_{D}
removes the effect of low sun angle and reduces the scale of values to between
0 and 1.
K_{T} = K_{N} + K_{D}  
 The ratio
between direct normal irradiance
and tracking extraterrestrial
radiation, used as a normalization of the direct normal irradiance because
K_{N} removes the effect of low sun angle and reduces the scale
of values to between 0 and 1.
K_{T} = K_{N} + K_{D}  
 The ratio
between global horizontal radiation
and extraterrestrial radiation,
used as a normalization of the global horizontal radiation because K_{T}
removes the effect of low sun angle and reduces the scale of values to between
0 and 1.
K_{T} = K_{N} + K_{D}  
 Kilowatt,
or 1000 Watts, a unit of power.
 
 Kilowatthour,
a unit of energy equivalent to (1000 = kilo) x (3600 seconds) = 3,600,000
Joules, or 3.6 MJ; the amount of energy a kilowatt
source produces in one hour
