Solar Collectors Energy Storage And Materials

Solar Collectors, Energy Storage, and Materials covers the materials and basic components needed for solar thermal energy systems. Using thermal performance and durability as the major criteria, the twenty six chapters emphasize the modeling and assessment of devices rather than their application or cost. Each part begins with an overview and concludes with an assessment of current issues and opportunities. The contributors have been careful to document failures as well as successes in materials research. This is the fifth volume in a series that distills the results of the intensive research on and development of solar thermal energy conversion technologies from 1975 to 1986. Francis de Winter is President of the Altas Corporation, Santa Cruz, California and a member of the Santa Cruz Energy Advisory Committee. Contents: Solar Collectors. Collector Concepts and Designs.

Energy Storage not only plays an important role in conservinq the energy but also improves the performance and reliability of a wide range of energy systems. Energy storagp. leads to saving of premium fuels and makes the system morA cost effective by reducing the wastage of energy. In most systems there is a mismatch between the energy supply and energy demand. The energy storage can even out this imbalance and thereby help in savings of capital costs. Enerqy storage is all the more important where the enerqy source is intermittent such as Solar Energy. The use of jntermittent energy sources is likely to grow. If more and more solar energy is to be used for domestic and industrial applications then energy storage is very crucial. If no storage is used in solar energy systems then the major part of the energy demand will be met by the back-up or auxiliary energy and therefore the so called annual solar load fract]on will be very low. In case of solar energy, both short term and long term energy storage systems can be used whjch can adjust the phase difference between solar energy supply and energy demand and can match seasonal demands to the solar availability respectively. Thermal energy storage can lead to capital cost savings, fuel savjngs, and fuel substitution in many application areas. Developing an optimum thermal storaqe system is as important an area of research as developinq an alternative source of energy.

Solar Energy Harvesting, Conversion, and Storage: Materials, Technologies, and Applications focuses on the current state of solar energy and the recent advancements in nanomaterials for different technologies, from harnessing energy to storage. The book covers different aspects of advanced nanomaterials for solar energy, rapid developments in solar thermal and hot water systems, and PV and CSP technologies. In addition, sections cover storing harnessed solar/heat energy using different available energy storage technologies, including phase change materials (PCMs), batteries, and supercapacitors. Various applications such as agriculture and aquaculture, desalination, domestic appliances, and transport are also explored. Provides an overview of solar energy harvesting technologies, energy storage technologies, and the role of advanced nanomaterials in solar energy Explores applications of technology in the fields of agriculture, aquaculture, desalination and transport Includes discussion of current policies, strategies and socioeconomic analysis and challenges

The main objective of writing the three volume 'Advances in Solar Energy Technology' is to consolidate all the relevant latest information available in the field of solar energy (applied and theoretical in nature) and to as sist both the students ( i. e. undergraduate, postgraduate, research scholars etc.) and the professionals (i.e. consulting, design and contracting firms). I have discussed each and every topic in depth rather than a cursory overview. All the material required on a particular topic is included in the chapter and I have wherever possible given useful relationships in equation, graphical and tabular form. It is hoped that this completed Solar Energy Technol ogy will serve the best source material in this field. The first chapter deals with the evacuated tubular col lecors suitable to operate at a temperature of about 150°C with a daily energy collector efficiency in excess of 40 per cent. These collectors thus would be useful for efficient operation of Solar Airconditioning System, Power Generation and Process Heat System. Various advanced features like vacuum insulation, selective black coating, anti-reflective coating, heat pipe, cusp reflector, etc., used in designing this advanced type of collector are discussed separately in this chapter. Transient mathematical model for its perfor mance prediction and different designs of evacuated tubular collectors commercially produced in different countries of the world are described in brief to give the reader a good picture about their scopr and working.

Drawing on the experience of some of the foremost experts in the field, this easy-to-use and affordable pocket reference includes a wealth of information relating to solar energy and solar energy technologies. Topics covered range from solar angles, sun path diagrams, solar radiation and radiative properties of materials through to thermal collectors, thermal energy storage, photovoltaics and daylighting. The book also includes conversion factors and constants and is peppered throughout with helpful illustrations, equations and explanations. Anyone with an interest in solar energy, including professional architects and engineers, home builders, academic researchers, students and energy consultants will find a host of answers in this book – a practical assimilation of data, fundamentals and guidelines for application.
