25. The National Solar Radiation Database gives us TMY (typical meteorological year) radiation data for cities across the US

26. A computer simulation (TRNSYS) uses that data to give us the amount of radiation on a tilted surface.

27. Denver, 45 degree, 20.89 MJ/m2 day, which is Mega Joules (106) per square meter for a day (1839 BTU/ft2 day)

28. SRCC (Solar Rating and Certification Center)

29. Joule is the SI standard unit of energy (equivalent to a BTU)

30. A Watt is Power in the SI units system.

31. Also know as a Joule/Sec (BTU/hr)18
