This book provides a technical overview of low-costparabolic trough collector (PTCs) prototypes for low-temperature heat demand.It begins with a comprehensive but concise summary of the state-of-the-art inPTCs, and presents a detailed mathematical model of such systems. Subsequentchapters describe the construction and materials used in the manufacture of PTCprototypes, and offers technical solutions to overcome design problems.Finally, it provides an accessible guide to the standards used to test andevaluate the performance of PTCs. Offering a valuable resource to engineeringresearchers and practitioners, it is also suitable for students of solarthermal systems, renewable energy and applied physics.
