$689

Hot Water from the Sun: A Consumer Guide to Solar Water Heating

$16.86

This guide has been written by experts in the field to provide you, a consumer, with information about the use of solar energy to heat the water you use in your home. It is no secret that energy costs have been rising rapidly in the past several years, and that conventional sources of energy are in short supply. As more and more people feel the impact of the rising cost and limited availability of some types of energy, increasing attention is being given to the energy available in sunlight. No longer just a fad for some individual experimenters, no longer only a subject for scientific and engineering studies, solar energy applications are now a matter of intense interest to almost everyone. Of all of the ways in which we can capture and use solar energy to meet our needs, providing hot water is perhaps the simplest and most economical for the homeowner. Many manufacturers now make equipment and systems to provide solar-heated water, and many firms around the country are qualified to install, maintain, and service them. The Federal government and several states even provide tax credits to help cover the cost of solar energy systems. But deciding to buy and install a solar hot water system still requires you to consider a number of factors—whether the system will save you money now or in the future, what kind of system to buy and from whom to buy it, whether to install it yourself or have it installed, and similar matters. This guide is designed to provide some of the information you will need to make these decisions, and to tell you where to get the rest of the information you may need to install or have installed a satisfactory solar hot water system.

In order to facilitate detailed solar system simulations and to make such simulations readily available to solar engineers in their daily practice of system dimensioning and performance calculations, user friendly software for personal computers has been developed as a system specific simulation program for a frequently installed group of water based solar system types. The program package has been developed as part of the OPSYS R&D-program of the Commission of the European Communities and has been named EURSOL. The set of system configurations considered includes different types of thermal solar systems for space heating and hot water production. The simulations are based on validated physical system models. The program offers complete freedom with regard to all parameters describing the systems and includes on-line help, economic evaluations and graphical output. This book describes the system considered in EURSOL, the mathematical algorithm, the physical model of each component used, the processing of solar radiation data and the economic evaluation criteria. Although the book is mainly a manual for the use of the simulation program, it is also a guide for the development of simplified simulation models for solar systems.
