Technologies that can contribute to the reduction of greenhouse gases are mandatory, and those based on solar energy are good candidates to achieve this. In this sense, massive solar thermal collectors are suitable technologies for supplying the primary energy demand of buildings. To design these devices, it is necessary to fully understand the physics of the problem before proposing any new optimized solution. This review aims to briefly summarize significant aspects regarding the current state of development of these solar technologies. Attention is paid to works devoted to experimental studies to analyze the behavior of these systems, as well as numerical models to predict the physics of the problem. Furthermore, the future directions and prospects in the field of massive collectors are briefly described. The main novelty of this review is to provide a comprehensive overview that summarizes the works done so far in the field over the past 30 years, which allows the reader to delve deeper into the topic. According to the reviewed works, it can be concluded that these technologies can contribute to the reduction of greenhouse gases while at the same time being excellent examples of the integration of solar energy devices with buildings.

“…The water heating system enhance the efficiency to transfer heat rate to open environment when come in contact with barriers, pipe in helping to decrease the speed of the liquid [3]. Generally the roof system produces hot water with capacity of 25litre/day with 60degree temperature in hot days of summers with 28degree ceiling temperature [4]. If we heat the water by covering the system with phase change material than 5-7 degree of benefit in prolonged stored water [5].…”

As the study proposed an appraisal for the working of Solar Water Heater System on tribal of Himalayan Areas is important to keen learn the power of nature. Our nature blessed us with so many blessings and one of them is sun. The continous change in climate that affects the ambient temperature and water in so many ways. So its our time to take an action to save our nature's earth by utilising different locally available materials, techniques to stop such activities that harm us and our surrounding. As water is one of the important and basic requirements for everyone. And in hilly areas where the temperature is low , the basic requirement is hot water. As the basic source of income for the local residents at these areas are mostly depend on tourist visits . So their restful environment and needs must be a provision. As the Solar water Heater system is costly way as one time investment but later it helps in several ways. Solar energy is one the best alternative way to replace the traditional requirement to heat the water like coal, gas, diesel etc. This system is designed to meet the energy demands. The size of the system depend upon the availability of the solar radiation, temperature and the orientation of the building. The given comprehension helps to understand the requirement and its working

In the realm of renewable energy, the optimization of solar water heating (SWH) systems stands paramount for addressing the escalating energy demands. This investigation delves into the pivotal role of design configurations in augmenting the efficiency of SWH systems, with a focus on diverse climatic and locational contexts. Employing the k-omega turbulence model within the ANSYS software framework, a meticulous evaluation of three distinct design configurations, namely, tube-over-plate, tube-under-plate, and tube-in-line-with-plate, is presented. The essence of this study lies not merely in delineating the intrinsic characteristics of these configurations but in a comparative assessment of their efficiencies to ascertain the most efficacious design for superior SWH performance. The adoption of the k-omega turbulence model is instrumental in capturing the intricate fluid dynamics that significantly influence SWH efficiency. The findings reveal that the tube-under-plate configuration exhibits remarkable efficiency, while the tube-in-line-with-plate arrangement demonstrates comparably effective performance. These insights represent a substantial contribution to the advancement of water heating technology, paving the way for more effective and sustainable energy solutions.
