“…The joint (4) allows the fFPSC to rotate around the E-W axis, while the threaded rods (5) are used to precisely adjust the angle of inclination to the horizontal (the optimal angle β=34° for the desired location is determined according to the recommendations by [33]. The upper water tank (6), with a diameter of 800 mm and a volume of 250 l, has a built-in float inside to maintain the desired water level, which is read on the water level meter (7) on the outside. The tank (6), which stands on a tank truss (8) with a height of 1800 mm, has two manual safety valves at the outlet (at the bottom): discharge valve (9)for emergency draining and stop valve (10)for emergency use to prevent unwanted delivery of water to the fFPSC.…”

To improve solar collector (SC) efficiency, a variety of designs and materials have been introduced into production practice. Studies describing SC specifics, therefore, are particularly valuable to the scientific community as they contribute to the overall body of knowledge and constant improvement the in the scientific field. In that regard, the study presented in this paper analyses the thermal performance of the fixed flat-plate collector (fFPSC) with an Sn-Al2O3 selective absorber. The fFPSC design utilizes gravity water flow in an open loop system. A two-month study was conducted to perform the analysis. The experiment was based on measurements of water flow in the fFPSC, the water temperature at the fFPSC inlet and outlet, and solar radiation intensity on a horizontal surface. Results for three randomly selected measurement days have shown that fFPSC can achieve relatively satisfactory values for average daily specific heat power, thermal efficiency, and inlet-outlet water temperature gradient, respectively: June 29 (381.78 W/m2, 60.67%, and 9.06 ?C), June 30 (364.33 W/m2, 59.43%, and 7.46 ?C), and July 15 (373.06 W/m2, 59.85%, and 8.69 ?C). Apart from the relatively good measurement results, this type of SC does not require circulating pumps for operation, which brings a double advantage: energy saving and energy production.

“…However, it has low efficiency compared to concentrating solar collectors. Flat plate collectors are most suitable for hot water at a low demand temperature of about 30-70 [61]. Based on Figure 9a, high-frequency solar radiation penetrates the collectors via glass cover, reducing heat loss by convection.…”

The rising energy demand necessitates a rapid transition to renewable energy and efficient technologies. The Nigerian household sector consumes enormous energy to meet domestic needs such as water heating. Furthermore, rising electricity costs hinders the commercial use of electric water heaters. As a result, energy users rely on conventional methods of heating water. In general, over-reliance on traditional water-heating systems have resulted in envi-ronmental degradation and public health crises. Adopting energy-efficient technologies may improve energy security, mitigate energy crises, reduce costs, and further optimize household energy consumption. This paper provides a comprehensive review of existing and emerging water-heating systems with a summary of recent innovations in water- heating systems. Var-ious types of hybrid and renewable water heating systems, as well as their configurations, are examined. In addition, relevant studies on different water-heating technologies are reviewed and classified according to their contribution, study type, and technology. The review findings are well articulated, and policy recommendations for solar water heating systems are made. This review's findings identify research gaps in the hybrid water-heating technology in Nige-ria. This survey provides insight into solar and hybrid solar systems as an alternative solution to fossil-fuel-based water heating systems.

“…Energy demands and global warming are increasing as a consequence of the use of conventional energy sources (fossil fuel, gasoline, gas and charcoal) that satisfy around 80% of the global demand for energy [ 1 ]. During the last few years, the total carbon dioxide emissions have increased by 54% demonstrating the dominance of fossil fuels worldwide [ 2 , 3 ].…”

A Highly Stable and Sustainable Low-Temperature Selective Absorber: Structural and Ageing Characterisation

et al. 2022

View full text Add to dashboard Cite

Solar absorbers in a three-layer configuration have been prepared by dip-coating onto aluminium substrates. They are constituted by two spinel layers with one silica layer on the top and values of solar absorptance above 0.950 and thermal emittance below 0.04 were obtained. The effects of using different sintering conditions of the upper silica layer on the optical behaviour and durability tests have been studied. Results obtained in accelerated ageing methods, such as thermal stability tests and condensation tests, clearly show that the proposed selective absorber exhibits excellent thermal stability and very good humidity resistance. The results show that the protective action is due not only to the silica layer but also to the alumina layer produced during the absorber preparation. The phase composition of the individual layers was independently confirmed using X-ray diffraction and corroborated by X-ray Photoelectron Spectroscopy. Spinel-like phases were obtained in both the first and second layers. The ageing study shows that the three-layer configuration proposed has a very high potential, in terms of both durability and optical behaviour, for solar thermal low-temperature applications.
