Computations of Daily Solar Radiation on Inclined Surfaces


Book Description

The quantity of solar radiation impinging on the surface of materials is of extreme importance to scientists concerned with outdoor weathering of materials. Forecasting this solar radiation load and its effects is difficult because of the many factors (astronomical, atmospheric, and material surface conditions) that may alter the quality and quantity, and hence the effects of the incoming radiation. This report deals with the theoretical computation of the angle at which samples of materials should be exposed if they are to receive maximum solar radiation, taking into consideration only the uniqueness of the astronomical and surface position factors. Data summaries are presented that show the amount of radiation impinging on the surface of materials inclined at different angles for worldwide locations.




An Introduction To Solar Radiation


Book Description

An Introduction to Solar Radiation is an introductory text on solar radiation, with emphasis on the methods of calculation for determining the amount of solar radiation incident on a surface on the earth. Topics covered include the astronomical relationship between the sun and the earth; thermal radiation; the solar constant and its spectral distribution; and extraterrestrial solar irradiation. This book is comprised of 12 chapters and begins with an overview of the trigonometric relationships between the sun-earth line and the position of an inclined surface, followed by a discussion on the characteristics of blackbody radiation. The next chapter focuses on the solar constant and its spectral distribution, paying particular attention to extraterrestrial solar spectral irradiance and the sun's blackbody temperature. Subsequent chapters explore extraterrestrial and radiation incident on inclined planes; the optics of a cloudless-sky atmosphere; solar spectral radiation and total (broadband) radiation under cloudless skies; and solar radiation arriving at horizontal surfaces on the earth through cloudy skies. The ground albedo and its spectral and angular variation are also described, along with insolation on inclined surfaces. The last chapter is devoted to instruments for measuring solar radiation, including pyrheliometers and pyranometers. This monograph will serve as a useful guide for energy analysts, designers of thermal devices, architects and engineers, agronomists, and hydrologists as well as senior graduate students.







Solar and Infrared Radiation Measurements, Second Edition


Book Description

The rather specialized field of solar and infrared radiation measurements has become increasingly important due to the increased demands by the renewable energy and climate change research communities for data with higher accuracy and increased temporal and spatial resolutions. Recent advances in radiometry, measurement systems, and information dissemination also have increased the need for refreshing the literature available for this topic. This book provides the reader with an up-to-date review of the important aspects of solar and infrared radiation measurements: radiometer design; equipment installation, operation, maintenance, and calibration; data quality assessment parameters; and the knowledge necessary to properly interpret and apply the measured data to a variety of topics. Each of the authors has more than 40 years of experience with this subject, primarily as the result of developing and operating multiple measurement stations, working with the industry to improve radiometry, and conducting various research projects. The book’s scope and subject matter have been designed to help a wide audience gain a general understanding of this subject and to serve as a technical reference. A student new to the field will benefit from the review of terminology and the historical perspective for radiometry before addressing more detailed topics in radiometry that we hope will be of interest to the more experienced reader.  Describes the strengths and weaknesses of irradiance instruments  Provides detailed information on how to assess uncertainty in measurements  Offers comprehensive background information needed to understand the use of solar instrumentation  Discusses design concepts for shadowband radiometers, sky imagers, and satellite-based estimates of solar irradiance at the Earth’s surface  Includes chapter-end questions, references, and useful links










Modeling Solar Radiation at the Earth's Surface


Book Description

Solar radiation data is important for a wide range of applications, e.g. in engineering, agriculture, health sector, and in many fields of the natural sciences. A few examples showing the diversity of applications may include: architecture and building design, e.g. air conditioning and cooling systems; solar heating system design and use; solar power generation; evaporation and irrigation; calculation of water requirements for crops; monitoring plant growth and disease control; skin cancer research.




European Solar Radiation Atlas


Book Description

This atlas is a revised and updated version of the European Solar Radiation Atlas published in 1984. The revised version contains tables and maps displaying monthly means of global, diffuse and beam solar radiation as well as sunhours for a large number of represenative sites in Europe. Tables show radiation on both horizontal and inclined surfaces. The revisions reflect the political developments in the European Union and within neighbouring countries. The presentation of the tables has been improved and additional information is included. An enlarged text section provides an introduction to the systematics of solar radiation measurement and calculation. The solar data presented in this book is a useful source of information for the estimation of the energy harvest potential for solar systems. The data base is provided on two 3 1/2" disks for more ease in computer assisted design work.
