Fuel supply and inflationary prices have forced us to'consider alternate energy sources as a means of preserving our standard of living, industrial society, and economic stability. One sucli alternative is solar. Presently, foreign crude oil provides the raw material for about one-half the liquid fuel production in the U.S. Political instability in foreign - oil-producing countries underscores the need to decrease our ever-growing dependency on foreign energy sources and to lessen our vulnerability to such imports. Solar energy as an alternate can be used as a renewable domestic energy source and to supplement our increasing appetitefor oil. To help bring about the potentia/ for solarenergy,'tfiere must be a cadre of trained technicians to design, install, troubleshoot, and market solar energy so that the consumer can feel comfort-Able in the market's ability to service and react to his/her solar energy needs. With the support of the National Science Foundation, NavarroCollege, . in consortium with North Lake College, Brevard Community College, Cerro Coso Community College, and Malaspina College, has developed andpilot tested a two-year associate degree curriculum to train 'solartechnicians. It can be duplicated or replicated by othereducational institutions for their training needs. The two-year technician program prepares a person to: 1) apply knowledge to science and mathematics extensively and render direct technical assistance to s,pientists and engineers engaged in solar gnergy research and experimentation; 2) design, plan, supervise, and assist in installation of both simple and complex solar systems and solar control devices; 3) supervise, or execute, the operation, maintenance andrepair of simple and comple2 solar systems and solar controlsYstems; 4) design, plan, and estimate costs as a field representative or salesperson for a manufacturer ordistributor of solar equipment; 5) prepare or interpret drawings andsketches and write specifications or procedures for work related to solar systems; and 6) work with and communicate with both the public and other employees regarding the entire fiel4 of solar energy. ' This curriculum consists of nine volumes: 1) an Instructor's Guide for the elevensolar courses, to include references, educational objectives, transparency wasters, pre-tests and post-tests, and representative student labs; 2) an Implementation Guide addressingequipment, commitment, and elemaits to'be considered before setting up asolai' program; 3) Student Material for each of seven of the coresolar courses: a) Materials, Materials Handling, and Fabrication Processes; ,b) Sizing, Design, and Retrofie; c) Collectors and Energy Seorage; d) Non-Residential Applications; e) Energy Conservation and Passive Design; f) Codes, Legalities, Consumerism, and Economics; g) Operational Diagnosis. V ACKNOWLEDGMENTS Throughout this project, many people and institutions have contributed greatly to the development:, pilot test, and completion of the solar technology curriculum. First, this project owes a debt of gratitude to the National Science Foundation whose support and encouragement have made this project possible. Specifically, two individuals formerly with the National Science Foundation deserve recognition: Dr. Bill Aldridge and,Dr: Gregg Edwards. 4 Appreciation is extended to thos members who served on the Advisory Committee and provided valuable input to module content, text format, and the pilot test plan and evaluation: Tom Hindes, (Chair for Phase II and III), Ohio State University. Dr. Phil DiLavore, (Chair for Phase I), Indiana State University. Dr. David Gavenda, University of Texas at Austin. Dr. Milton E. Larson, Colorado State University. Dr. Jeff Morehouse, Science Applications, Inc. Glenn Meredeith, President, Ham-Mer Consulting Engineers, Inc. Pearley Cunningham, Community College of Allegheny County. Dr. Max Jobe, (Eveluator), East Texas State, University. It would have been impossible to complete this project and all the curriculum materials if it had not been for the Technical Coordinators and the Cooperating Institutions in this Consortium: William Everet Bolin, North Lake College, Dallas,-Texas. Ray Mudrak, Brevard Community College, Titusville, Florida. Stephen Pomroy, Navarro College, Corsicana, Texas. Jeff Jacobs, Cerro Coso Community College, Ridgecrest, California. Dr. Jim Slater, Malaspina College, Nanaimo, British Columbia. A special thanks is sent to Dr. Pete Signell and his staff, Tom Burt and Jodee Fortino, and the resources at Michigan State University for their help in providing computer assistance to produce the printed masters for the project and permanently store the curriculum in their data bank. There are others who have contributed to the content, technical authority, and clericaltasks of the project who have made this a learning
