“…The surface of the central collector tube is coated with a dark-colored solar selective material that promotes maximum solar absorption, which in turn promotes higher temperatures in the working fluid. The working fluid flow rate is regulated by valves to optimize maximum energy transfer [ 32 ].…”

The global demand for energy is increasing and the detrimental consequences of rising greenhouse gas emissions, global warming and environmental degradation present major challenges. Solar energy offers a clean and viable renewable energy source with the potential to alleviate the detrimental consequences normally associated with fossil fuel-based energy generation. However, there are two inherent problems associated with conventional solar thermal energy conversion systems. The first involves low thermal conductivity values of heat transfer fluids, and the second involves the poor optical properties of many absorbers and their coating. Hence, there is an imperative need to improve both thermal and optical properties of current solar conversion systems. Direct solar thermal absorption collectors incorporating a nanofluid offers the opportunity to achieve significant improvements in both optical and thermal performance. Since nanofluids offer much greater heat absorbing and heat transfer properties compared to traditional working fluids. The review summarizes current research in this innovative field. It discusses direct solar absorber collectors and methods for improving their performance. This is followed by a discussion of the various types of nanofluids available and the synthesis techniques used to manufacture them. In closing, a brief discussion of nanofluid property modelling is also presented.

“…Side-by-side testing of prototypes resulted in a maximum temperature difference between the inlet and outlet of the cylindrical batch system of 27.8°C with a maximum efficiency of 41.8%. [7] Tripanagnostopoulos and Souliotis experimented on optimizing an integrated storage-collector batch solar water heater that contained two cylindrical tanks and a compound parabolic concentrator made of aluminum mylar glazed with an iron oxide and black matte absorbing surface [1] A simpler batch solar water heater has been investigated by Akuffo and Jackson in Ghana. The integrated storage-collector unit was a rectangular galvanized steel box with a total storage capacity of 90L.…”

This paper presents an overview of the use of solar energy for domestic water heating purposes. In addition, the results of a preliminary research to develop a low cost system for heating water using solar energy, a green energy source is also included. For the system presented herewith, the absorption of sunrays radiated heat is by means of a thermal collector. The heating and recirculation process are automatically controlled using sensors, actuators, and a Programmable Logic Controller (PLC). The results obtained indicates that the system presented have the potential to supply enough hot water to meet the requirements for domestic consumption.
