A solar water heater (SWH) converts solar radiation into thermal energy for various purposes, and its technology has experienced numerous developments. Many studies have focused on developing, optimizing, and analyzing the technological configurations of SWH to improve its thermal efficiency, but they rarely achieve 80% efficiency. This review aims to provide a broad overview of SWH, including the energetic and exergetic approaches and analyses, technological development, and examines advantages, disadvantages, and further developments. Various collectors of the SWH and related studies are also highlighted, and the results identify the technical and policy challenges of the implementation. Suggested potential solutions to these challenges are presented with further directions. Furthermore, this study also discusses the limitations of the current SWH technology by presenting the specifications and characteristics. It also presents the mathematical equation model often used, the technology potential, and the results of the latest studies and developments regarding SWH technology. The prospects for further development of the most promising SWH should be analyzed.

Solar thermal energy was utilized to heat water for its useful applications. Moreover, solar water heaters have become essential in our lives, and using renewable energy sources is becoming more popular. The current effort is to test and find the effectual solar water heating system. Solar water heater designs have been suggested and produced within two methods whereas forced circulation using a mechanical pump and natural circulation without the use of a pump also recognized as thermosiphon solar water heater. This research was to analyse most efficient Flat Plate Collector (FPC) in terms of heat absorption on Thermosiphon Effect due to energy collection by different colour, material, and glazing. This experiment uses Solar Energy Trainer and MATLAB software to compare the impact of several forms FPC on heat absorption of thermosiphon effect in solar water heater. The most efficient FPC in terms of colour is black collector with higher efficiency of 9.3% compared to white while most efficient FPC in terms of material and glazing are copper and double-glazing collector with 10.86% and 11.15% respectively. The experiment and analysis show that various types of FPC with good heat absorber have higher efficiency.

“…The increase in nanoparticle concentrations enhanced the thermal energy gain and led to an increase in the fluid outlet temperature. Shamsul Azha et al [12] presented a study that includes a review of ten methods for improving the heat transfer using vibration and its possible application to flat plat solar collector. These include: the use of nanofluids, absorbent coatings, (PCM), thermal performance enhancers, FPSC design modifications, the use of polymeric materials, heat loss reduction, mini-channel and micro-channel, and enhanced heat transfer using vibration.…”

The air solar collectors are one of the necessary equipment for heating by increase the induced air temperatures. The thermal analysis of the solar air collector for the three different absorbers, flat and double slope (15, 30) degrees was studied numerically by employing a FORTRAN 90 program. The 3D steady-state forced convection turbulent technique was used to solve the Navier-Stokes with energy equations. The turbulence effect was modeled by using k-ε two equation model. The discretization of governing equations was done by finite volume technique. The test is carried out under the weather conditions of the Baghdad-Iraq region during the month of Jun. The results exhibit that the air temperatures increase when used the double slope collector, also the performance of air solar collector is enhanced thermally. The average 15° angle plate is higher than the flat and the 30° angle plates from 8am to 11am and from 1pm to 6pm, it is best slope angle.
