Solar water heating systems and their market trends
TL;DR: An overview of various types of solar assisted water heating systems and their market potential is presented in this article, where the authors analyze the performances along with how unique they are of different types of SWH systems and the later part of the paper covers its economic aspects.

Integrated collector storage solar water heaters
TL;DR: The Integrated Collector Storage Solar Water Heater (ICSSWH) developed from early systems comprised simply of a simple black tank placed in the sun, by its combined collection and storage function suffers substantial heat losses to ambient, especially at night-time and non-collection periods as discussed by the authors.
Journal ArticleDOI
Technical assessment of solar thermal energy storage technologies
TL;DR: In this paper, the basic concepts, systems design, and the latest developments in (sensible and latent heat) thermal energy storage are reviewed. And the problems encountered during the systems operation are highlighted.

Modelling of an ICS solar water heater using artificial neural networks and TRNSYS
TL;DR: A study, in which a suitable artificial neural network (ANN) and TRNSYS are combined in order to predict the performance of an Integrated Collector Storage prototype, is presented and it is shown that this new method can be used effectively for such predictions.

Comparison of solar concentrators
TL;DR: In this paper, the authors compared a variety of solar concentrators in terms of their most important general characteristics, namely concentration, acceptance angle, sensitivity to mirror errors, size of reflector area and average number of reflections.

Theoretical and experimental studies on collector/storage type solar water heater
H.P. Garg,Usha Rani +1 more
TL;DR: In this article, the transient performance of a built-in-storage solar water heater is predicted by solving the mathematical models consisting of energy balance equations which are written on different collector nodes by considering their capacity effects and various heat loss effects.

Prospects for integrated storage collector systems in central Europe
A. Goetzberger,M. Rommel +1 more
TL;DR: In this article, the concept of an improved integrated storage collector is evaluated for Central European temperature and radiation conditions where integrated storage collectors have so far not been used, and it is found that the ISC is superior to active flat plate systems and thermosyphon systems.

Asymmetrical non-imaging cylindrical solar concentrators
David R. Mills,J.E. Giutronich +1 more
TL;DR: In this paper, both Parabolic and Non-Parabolic Asymmetrical Concentrators are examined and compared with symmetrical designs, and the advantages of asymmetrical systems are: (1) a concentration vs time-of-day relationship which can be designed to compensate for projected solar area fall-off in early morning and late afternoon, allowing more uniform output where this is desirable; (2) greater operational flexibility for accommodating unexpected fluctuations in demand; (3) easier adaptation to vacuum-insulated receivers in one configuration; (4) substantially increased concentration and energy collection per unit of
