Solar energy is one of the most promising forms of alternative energy because it has no adverse effects on the environment and is entirely free. Converting solar energy into thermal energy is the most common and straightforward method; the efficiency of solar thermal conversion is approximately 70 percent. The intermittent nature of solar energy availability affects the performance of solar water heaters (SWH), which lowers the usefulness of solar energy in residential and commercial settings, particularly for water heating. Even at low temperatures, the performance of a collector can be improved by using low-density polyethylene (LDPE) glazing instead of traditional glass because it is less expensive and lighter than glass. Using a comprehensive experimental-simulative study, the Glass Solar water heater (glass SWH) and the low-density polyethylene solar water heater (LDPE SWH) are analyzed, examined, and compared in this work. These solar water heaters have galvanized iron (GI) as their absorber material. The SWHs were operated in a closed loop at a constant mass flow rate of 0.013 kg/s, and a 4E analysis (which stands for energy, exergy, economics, and efficiency recovery ratio) was carried out. This analysis included a look at the dynamic time, uncertainty, weight reduction, carbon footprint, and series connection. An LDPE SWH has an energy efficiency that is 5.57% and an exergy efficiency that is 3.2% higher than a glass SWH. The weight of the LDPE SWH is 32.56% lower than that of the glass SWH. Compared to the price of a conventional geyser, installing our SWH results in a cost savings of 40.9%, and monthly energy costs are reduced by an average of 25.5%. Compared to October, September has the quickest dynamic time to reach the desired temperature, while October has the most significant dynamic time. The efficiency recovery ratio (ERR) of a glass SWH is 0.0239% lower than that of an LDPE SWH. LDPE SWHs had a carbon credit worth INR 294.44 more than glass SWHs. The findings of these tests demonstrate that the LDPE SWH is a practical replacement for traditional means of heating water, such as SWHs and geysers.

The flat plate solar collector (FPSC) is a well-known energy harvesting tool that minimizes the strain on the traditional energy production approach while also promoting the future use of renewable energy. Thus, Increasing the performance of this collector is worth the effort. As the world's energy consumption continues to grow, there has been an increased focus on the potential for nanotechnology improvements to reduce energy usage. Recent scientific research has shown that the application of nanotechnology can increase the efficiency of the traditional glass cover of FPSC. Antireflective and self-cleaning nanocoating has recently attracted a lot of attention for both its important aspects and wide practical applications. In the current study, there are many sections to the review as follows: (a) general overview of the fundamental theoretical frameworks of antireflection and self-cleaning technology; (b) detailed fabrication methods for both antireflection and self-cleaning coating; (c) A range of anti-reflection coating materials used to add new functionalities for glass cover of FPSC; (d) present the literature of the studies of anti-reflection and self-cleaning coating application in FPSC.

“…The study also notes that experimental and theoretical calculations had a discrepancy of typically below 20%, primarily attributed to measurement instrument uncertainties. Sekhar et al 13 studied the effectiveness of a flat-plate solar collector by analyzing factors like glazing material choice, solar irradiance, overall heat loss coefficient, and heat removal factor. Polyvinyl Fluoride showed the highest efficiency due to its favorable properties and high transmissivity.…”

A hybrid flat solar collector was manufactured from basic materials to combine the effects of both water and air solar heaters. The reason is to increase the amount of heat delivered to water by doubling the heat sources, one from the direct beam of sun and the other from the hot air delivered by the air solar heater. In addition, the flow of water inside the solar heater is made in a thin layer so that much heat can be gained by water per unit time. The outlet hot air of the solar air heater enters air ducts that pass through the solar water heater. With a constant water flowrate of 0.0167 kg/s, three different air velocities (1.7, 2.1, and 2.4 m/s) were applied to determine the optimum air velocity that results in the maximum outlet water temperature and the maximum removal factor FR for the solar water heater. The experiment was run from 10:00 a.m. to 2:00 p.m. every day during June 2023 and the data was recorded every 15 min. The data obtained from the experiment showed that the lowest air speed (1.7 m/s) results in the highest outlet water temperature (63°C) and heat removal factor FR (0.74).
