Drawing on the authors’ extensive research and project implementation around the globe, this book provides detailed knowledge for converting solar radiation into a suitable energy supply. It presents technical fundamentals to give a clear understanding of how solar energy can be captured for later use. The authors examine thermosolar collectors, photovoltaics modules, and other important types of solar receivers as well as cover typical cost-effective applications, including water pumping, residential electrification, lighting, small-scale irrigation, and more. Examples, case studies, and lessons learned from technical failures illustrate how to best implement solar energy projects.
