In the study, the photovoltaic thermal system using nanofluid as coolant is validated using numerical approach by comparing the experimental results and simulation results. Due to high cost and difficulty in preparing nanofluid, it is more practical to perform the study using numerical approach which is convenient and saves plenty of time. The photovoltaic thermal system is investigated numerically through Computational Fluid Dynamics Approach using Ansys 19.0 Fluent Software. The numerical study is based on different solar irradiation at different hours. The coolant that is selected in the study is aluminum oxide () water nanofluid. The validation study between the experimental results and simulation results are achieved by examining the photovoltaic (PV) surface temperature and nanofluid outlet temperature. The maximum percentage of error between experimental and simulation results of PV surface temperature and nanofluid outlet temperature are 12.66% and 7.89%. Also, the mean average percentage error (MAPE) are computed for PV surface temperature and nanofluid outlet temperature. The results for PV surface temperature and nanofluid outlet temperature are 10.31% and 6.67%. Since the MAPE results are within 10% or error, it proved that there is good accuracy between the simulation and experimental results.

“…Traditionally, fuel or other traditional energy sources have been used to heat the air for drying agricultural and industrial goods, making the process energy-intensive (Hasan, Togun, et al 2023). However, solar energy is a potential renewable energy source for drying, which can significantly reduce energy consumption and carbon footprint(Kamaruzzaman Sopian et al 2018). Sun drying is a natural and plentiful resource that is environmentally sustainable and cost-effective compared to traditional drying methods (A-dulaimi et al 2023).…”

The use of a V-corrugated plate absorber in a sun drying system (SDS) under the weather in Baghdad is the subject of this study's original investigation. Analysis of the effects of this novel design is the main goal of the research. To investigate temperature fluctuations inside the drying chamber, experimental tests were run. Initial temperatures for the V-shaped and flat plate designs were 47 °C and 43 °C, respectively, at 8:00 am. At 1:00 pm, when the sun's beams are vertically aligned and the solar radiation reaching the glass collector is at its highest, both arrangements experience temperature peaks. The sun's rays' shifting angles caused temperature drops after this peak, which reached minimums of 47 °C and 41 °C for the V-shaped and flat collector configurations, respectively. It's interesting to note that, compared to the flat plate design, the V-corrugated plate absorber continuously maintained higher temperatures throughout the day. Notably, the absorber showed improvements of 11.6 %, 19.2 %, and 14.6 % at the appropriate times. The study also emphasised the enhanced heat transfer efficiency of the V-shaped absorber, which was attributable to its capacity to withstand greater temperature differences between the input and output. Surprisingly, the V-shaped absorber outperformed efficiency values at 8:00 am and 5:00 pm by 73 % and 82 %, respectively, and reached a maximum thermal efficiency of 71% at 1:00 pm. The investigation focused on a significant 29 % performance differential between the two systems at 1:00 pm, when heat extraction is at its best. This finding highlights the effectiveness of the V-corrugated plate absorber in increasing energy efficiency. The study's findings emphasise the creativity and practicality of V-corrugated plate absorbers in enhancing the efficacy of sun drying systems, particularly in adverse weather situations.

“…For example, Cappelletti mentions that mono-crystalline PV cells have higher efficiency compared to poly-crystalline PV cells [18]. In terms of the working fluid, air is considered to be less efficient than water which itself is less efficient compared to various nanofluids [5,[19][20][21][22][23][24][25]. In terms of absorber configurations, the most common absorbers are serpentine, parallel, spiral, cross-fined absorbers amongst which, the spiral absorber is found to be the most efficient [2,[26][27][28][29][30][31][32].…”

Although, the effect of mass flow rate and solar irradiance variation is present in literature, it is still of significant interest to investigate the extent of the effect especially when utilizing a custom absorber design. In this paper, the effect of changing the mass flow rate and solar irradiance on the performance and temperature uniformity of a PVT using a custom spiral absorber design is simulated using ANSYS CFD software. By increasing the mass flow rate, the temperature uniformity and the performance parameters such as the average PV temperature, water outlet temperature, thermal and electrical efficiency all increase. By increasing the irradiance level, performance and temperature uniformity drop albeit at a smaller degree compared to change observed in mass flow rate variation. Amongst the tested range, the optimum mass flow rate and solar irradiance levels for best performance are 40 kg/h and 800 – 1000 , respectively.
