Solar Engineering

Solar energy comes to the earth as electromagnetic radiation. It has  properties in common with all other forms of electromagnetic radiation, as for example, in the relationship among its wavelength, its frequency and the speed of light. When electromagnetic radiation strikes an object it must be absorbed, reflected and/or tranmitted through the object. Extraterrestrial solar radiation is that reaching the earth’s outer atmosphere. The average monthly extraterrestrial solar radiation rate on a horizontal surface can be found for any month, for any latitude between
20o and 65o, from a table provided in this course. Solar declination, solar hour angle, and solar altitude angle are solar parameters, which can be used to describe the sun’s position at any location, at any time of the year and time of day. These parameters were discussed and means of calculating them were presented. Sunrise hour angle and sunset hour angle were also discussed and equations were given for their calculation. Beam radiation and diffuse radiation as two components of terrestrial radiation were described and discussed. The use of
Solar Radiation Data Manual for Flat-Plate and Concentrating Collectors, a publication of the National Renewable Energy Laboratory, was discussed as a source for a wide range of solar radiation data for various solar collector configurations
