“…Thus, the selection of nanofluid type in a PVT system is vital to ensure compatibility and meet the desired performance criteria. Table 6 summarizes studies involving PVT systems with nanofluids as coolant media, featuring different types and configurations [54,[137][138][139][140][141][142][143][144][145][146][147].…”

With the growing demand for photovoltaic (PV) systems as a source of energy generation that produces no greenhouse gas emissions, effective strategies are needed to address the inherent inefficiencies of PV systems. These systems typically absorb only approximately 15% of solar energy and experience performance degradation due to temperature increases during operation. To address these issues, PV–thermal (PVT) technology, which combines PV with a thermal absorber to dissipate excess heat and convert it into additional thermal energy, is being rapidly developed. This review presents an overview of various PVT technologies designed to prevent overheating in operational systems and to enhance heat transfer from the solar cells to the absorber. The methods explored include innovative absorber designs that focus on increasing the heat transfer contact surface, using mini/microchannels for improved heat transfer contiguity, and substituting traditional metal materials with polymers to reduce construction costs while utilizing polymer flexibility. The review also discusses incorporating phase change materials for latent heat absorption and using nanofluids as coolant mediums, which offer higher thermal conductivity than pure water. This review highlights significant observations and challenges associated with absorber design, mini/microchannels, polymer materials, phase change materials, and nanofluids in terms of PV waste heat dissipation. It includes a summary of relevant numerical and experimental studies to facilitate comparisons of each development approach.

“…In the absence of revenue, the economic analysis was performed using the annual worth (AW) method, which allows different technological alternatives to be evaluated. This method is most suitable for many engineering studies (Tian et al 2021;Guo-Yan et al 2008), unlike the net present value (NPV), which is preferred in accounting (Kelly and Leahy 2019). The AW considers all costs disbursed over time and converts them into a series of annual payments that can be compared between alternatives.…”

The removal of organic matter from Pisco production wastewater was evaluated using coagulation/flocculation, filtration as a pre-treatment and solar photo-Fenton, with the use of two types of photoreactors: compound parabolic collectors (CPC) and flat plate (FP), with and without utilising the ozonation process. The overall removal efficiency for COD was 63% and 15% using FP and CPC, respectively. Also, for the overall removal efficiency of polyphenols, a percentage of 73% and 43% were obtained using FP and CPC, respectively. When ozone was used in the solar photoreactors, the resulting trends were similar. COD and polyphenol removal, using an FP photoreactor in the solar photo-Fenton/O3 process, resulted in values of 98.8% and 86.2% after the process. COD and polyphenol removal, using solar photo-Fenton/O3 process in a CPC, resulted in values of 49.5% and 72.4%, respectively. The economic indicators of annual worth and economic treatment capacity established that FP reactors represent lower costs than CPCs. These results were corroborated by the economic analyses of the evolution of costs versus COD removed as well as by the cash flow diagrams projected for 5, 10 and 15 years.

“…This makes them a good potential to be used as a cooling fluid. In recent research, nanofluids such as Copper oxide, Aluminium oxide or Magnesium oxide as a cooling medium to cool down solar panels [10] [11]. The cooling efficiency increment of both the nanofluids, as shown by Amalraj and Michael [10], averaged around 18.2 %.…”

“…The cooling efficiency increment of both the nanofluids, as shown by Amalraj and Michael [10], averaged around 18.2 %. On the other hand, Tian et al [11] showed that the addition of 1% of nanoparticles results in an increment of the exergy efficiency by 0.45% when the nanofluid is flowing at 30 litres/hour. The cooling technique is similar to forced water circulation whereby they used copper tubes to pump the nanofluids onto the solar panels and remove the heat effectively.…”

Solar panel is used to harvest solar energy through the photovoltaic panels to generate electricity. Due to the different intensity of the sun, the panel may be getting overheated during the operation which affect the performance. The research was conducted to analyse the efficiency of liquid immersion cooling technique with water, measure the differences of water and nanofluids under the liquid immersion technique, and determine the efficiency increase of the cooling system with additional cooling. The apparatus was set up to test the cooling system performance throughout the most active part of the day with sunlight. The collected data has shown an increase in the power efficiency of 12.66% in favour of silver nanofluid compared to water when the cooling system is attached with additional cooling capabilities. However, without the additional cooling capabilities, the difference in power output between silver nanofluid and water shows around 2.42% in favour of silver nanofluid. The use of nanofluid in this experiment indicates a noticeable increase in power efficiency through the ability to keep the panel better cooled throughout the day. This allows nanofluids to be used as a cooling fluid to remove heat form the solar panel.
