Clear-sky irradiance predictions for solar resource mapping and large-scale applications: Improved validation methodology and detailed performance analysis of 18 broadband radiative models
TL;DR: In this article, the intrinsic performance of 18 broadband radiative models is assessed, using high-quality datasets from five sites in widely different climates, and the results show that the inferior performance of models requiring little or no atmospheric inputs suggests that large scale solar resource products derived from them may be inappropriate for serious solar applications.

The absorption of radiation in solar stills
TL;DR: In this article, a method of calculating the fraction of incident solar radiation which is productively used in solar stills is presented, and the number of variables which can influence this make it necessary to standarize on set values of glass thickness and extinction coefficent and liner reflectance.

The Astronomical Almanac's algorithm for approximate solar position (1950 - 2050).
TL;DR: In this paper, an algorithm for the calculation of solar position that has a stated, and partially demonstrated, accuracy of 0.01 deg until the year 2050 is presented, using the same approach as an earlier paper by Walraven, but has a more simplified form.

Calculating the position of the sun
TL;DR: In this paper, the procedure for calculating the position of the sun by computer is discussed, and the equations used to generate the values in The American Ephemeris and Nautical Almanac are presented in a simplified form that allows the sun to be calculated rapidly to an accuracy of 0.01°.
