This guidebook for managers and other decision makers analyses all important aspects that have to be considered when evaluating photovoltaics as a potential option in the power-supply industry and industrial development. Since such an analysis is quite complex and requires know-how from several scientific disciplines, the book draws upon the expertise of about 40 invited experts. Consensus statements on some of the controversial items such as cost development or energy pay-back time are given. In addition, the book is rounded out by an evaluation of the technological status of photovoltaics. The Photovoltaics Guidebook for Decision Makers enables readers to form their own opinions, particularly on the realistic potential and role of photovoltaics in energy policy, the power-supply industry and industrial development.
