Bethesda, Maryland [RenewableEnergyAccess.com] Photovoltaic Systems - the first comprehensive guide to the installation of commercial and residential solar energy systems has been published by the National Joint Apprenticeship and Training Committee for the Electrical Industry (NJATC). Authored by Jim Dunlop, the textbook covers the principles of photovoltaics (PV) -- the direct conversion of solar energy into electricity -- and how to incorporate it into stand-alone or utility-connected electrical systems. Illustrations clarify concepts, photographs show how components are integrated to form complete PV systems. A CD-ROM provides interactive worksheets, quizzes, calculators, video clips and animated graphics depicting PV principles and operation and links to additional resources. NJATC is a joint program of the International Brotherhood of Electrical Workers (IBEW) and the National Electrical Contractors Association (NECA) that has been training journeymen in the design and installation of solar energy systems for more than a decade.
