Solar Resource Assessment and Economics

2.8 Discussion Activity


I want you to question why we do all of these time conversions for solar energy in this Discussion Activity. I have already stated that we use the conversions to relate time and angles together as solar energy specialists. Now, I would like you each to contribute your questions and perspective on the following topics:

  1. Solar time vs. clock time (What is the difference?)
  2. Analemma vs. time correction for longitude (What is the analemma in the sky representing? What is the connection between longitude and time?)
  3. Daylight savings (What insight have you gained about the use of daylight savings in society - useful, not so much, meh?)
  4. Equinox and solstice's role in SECS (These are key, critical points in time. What makes each special?)

This discussion will take place in the Lesson 2 Discussion Activity board in Canvas.

This is an open-ended discussion, and you may ask questions or raise your concerns with things that might still remain confusing.
