This publication contains student and teacher instructional materials for a course in residential solar systems. The text is designed either as a basic solar course or as a supplement to extend student skills in areas such as architectural drafting, air conditioning and refrigeration, and plumbing. The materials are presented in four units covering the following topics: fundamentals of solar systems; active solar heating systems; load calculations and solar cooling; and passive solar and other solar concepts. Each unit contains a unit objective, specific objectives, suggested activities, and instructional materials, such as an objective sheet, information sheet, transparency masters, assignment sheets, answers to assignment sheets, job sheets, a unit test, and answers to the test. Suggested references are listed, and the units are liberally illustrated. (KC)
