Harlan H. Bengtson, Ph.D., P.E.
Course Outline
This two-hour, on-line course describes the basic nature of solar energy (electromagnetic radiation) and how it behaves when it strikes an object. Solar variables such as declination, altitude angle, and hour angle are discussed and methods for determining their value are given. Methods of utilizing solar energy and means of estimating extraterrestrial and terrestrial solar energy are discussed.
This course includes
a multiple-choice quiz at the end, which is designed to enhance the understanding
of the course materials.
Learning Objective
At the conclusion of this material the student will:
- Know the different types of electromagnetic radiation and which are included in solar radiation;
- Be able to calculate wavelength if given frequency and frequency if given wavelength for specified electromagnetic radiation;
- Know the meaning of absorbance, reflectance and transmittance as applied to a surface receiving electromagnetic radiation and be able to make simple calculations with those parameters;
- Be able to obtain an estimated value for monthly averaged extraterrestrial radiation on a horizontal surface for a specified month and latitude between 20 and 65 degrees;
- Be able to obtain or calculate values for solar declination, solar hour angle, solar altitude angle, sunrise angle, and sunset angle and use them in calculations; and
- Know the major methods by which solar radiation is converted into other useable forms of energy.
Intended

Course Summary
Solar energy reaches the earth in the form of electromagnetic radiation. It can be absorbed by an object that it strikes and thus be converted to thermal energy (heat). Typical methods of utilizing solar energy include, space heating, water heating and generation of electricity. Several parameters that are used in solar energy calculations were presented and discussed. Means of estimating monthly average extraterrestrial and terrestrial solar radiation rates at a specified location were discussed.
Quiz
Once you finish studying the above course content, you need to take a quiz to obtain the PDH credits.
