  23. 23. Solar Radiation<br /><ul><li>Is Radiant energy from the sun (electromagnetic radiation) produced by a nuclear fusion reaction. Half of this radiation is in the Visible spectrum, the other half is mostly in the near infra-red spectrum of light.</li></ul>17<br />
  24. 24. <ul><li>Thermal systems use Diffuse and Direct Normal Light
  25. 25. The National Solar Radiation Database gives us TMY (typical meteorological year) radiation data for cities across the US
  26. 26. A computer simulation (TRNSYS) uses that data to give us the amount of radiation on a tilted surface.
  27. 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. 28. SRCC (Solar Rating and Certification Center)
  29. 29. Joule is the SI standard unit of energy (equivalent to a BTU)
  30. 30. A Watt is Power in the SI units system.
  31. 31. Also know as a Joule/Sec (BTU/hr)</li></ul>18<br />
  32. 32. Solar Thermal Collectors<br /><ul><li>Collect the suns radiation and transfer that to a fluid as it runs through them.
  33. 33. Water, Propylene Glycol, Oil, Air
  34. 34. High Temperature (Concentrating Systems), Industrial Power Generation
  35. 35. Medium Temperature (Evacuated Tubes)
  36. 36. Residential and Commercial
  37. 37. Low Temperature (Flat plates)
  38. 38. Unglazed (Pool Panels)</li></ul>19<br />
