The section covers:
- Design tables that allow you determine the benefit of reflectors of various sizes and to optimize the placement of the reflector.
- An easy to build earth-sun simulator that allows you to see how a reflector of a given size and shape will perform for any location at any time of the year at any hour of the day.
- Examples of the use of reflectors to improve collector performance.
Reflectors offer a uniquely effective way to increase the energy produced by a collector in that they increase the solar energy incident on the collector without increasing the heat losses from the collector -- so, you get both an increase in solar input and an increase in collector efficiency -- see the new section for more on this.

| This earth-simulator allows reflector performance to be seen for any location and for any time of year and for any time of day. A quick spin of the turntable shows the reflector light pattern for a full day. Can also be used for shading and lighting studies. Lots of fun! |
