The book "Effective Energy Metering of Solar Domestic Hot Water Systems" by Thomas Cleveland provides a comprehensive analysis and validation of methods for accurately and reliably measuring the electrical energy saved through the use of solar thermal energy in domestic hot water systems. It addresses the challenges associated with the current availability of thermal energy metering devices and emphasizes the need to develop a widely accepted method for measuring the thermal energy gain provided by solar thermal collectors. By closely monitoring energy flows in a residential system and testing various measurement methods, an experimentally validated approach is presented that enhances the confidence of consumers, policymakers, and utilities. This technical book is a valuable resource for anyone involved in the integration of solar thermal energy into national renewable energy standards.
