Beskrivning

The bible of solar engineering that translates solar energy theory to practice, revised and updatedThe updated Fifth Edition of Solar Engineering of Thermal Processes, Photovoltaics and Wind contains the fundamentals of solar energy and explains how we get energy from the sun. The authors—noted experts on the topic—provide an introduction to the technologies that harvest, store, and deliver solar energy, such as photovoltaics, solar heaters, and cells. The book also explores the applications of solar technologies and shows how they are applied in various sectors of the marketplace.The revised Fifth Edition offers guidance for using two key engineering software applications, Engineering Equation Solver (EES) and System Advisor Model (SAM). These applications aid in solving complex equations quickly and help with performing long-term or annual simulations. The new edition includes all-new examples, performance data, and photos of current solar energy applications. In addition, the chapter on concentrating solar power is updated and expanded. The practice problems in the Appendix are also updated, and instructors have access to an updated print Solutions Manual. This important book: • Covers all aspects of solar engineering from basic theory to the design of solar technology• Offers in-depth guidance and demonstrations of Engineering Equation Solver (EES) and System Advisor Model (SAM) software• Contains all-new examples, performance data, and photos of solar energy systems today• Includes updated simulation problems and a solutions manual for instructorsWritten for students and practicing professionals in power and energy industries as well as those in research and government labs, Solar Engineering of Thermal Processes, Fifth Edition continues to be the leading solar engineering text and reference.
