Solar electricity is a viable, environmentally sustainable alternative to the worlds energy supplies. In support, Dr. Krauter thoroughly examines the various technical parameters of photovoltaic systems. Study of performance and yield (including optical, thermal, and electrical parameters and interfaces) are analyzed. The net energy balance of photovoltaic systems from production, operation and maintenance, to recycling is explored. Professor Krauter demonstrates how the importance of accurate yield calculations, optimal system performance, and new prototypes aid in cost reductions. The potential of solar electric power generation as a means to significantly reduce CO2 emissions is also detailed. In addition, various locations for the production and installation of photovoltaic power plants are considered with surprising results. Examples, tables and figures are included.
