Currently, the use of renewable energy is a major necessity due to the rapid increase in energy consumption, along with the limited non-renewable energy resources. Photovoltaic (PV) modules, which convert sunlight into useful electrical energy, offer a sustainable alternative. One possible way of increasing the power generation of the PV module is the use of low-concentrator photovoltaic (LCPV). However, the high levels of concentrated solar radiation cause a significant increase in the temperatures of LCPV modules, resulting in a significant reduction in LCPV electrical power generation. To address this, the present study introduces a novel converging cooling channel designed for attachment to the rear side of monocrystalline LCPV modules. In this research, the response surface methodology (RSM) serves as the design of experiments tool to investigate the impact of six factors on the LCPV module temperature. These factors are fluid velocity (Vin), inlet temperature (Tin), channel outlet height (Hout), solar concentration ratio (CR), solar radiation, and wind speed. A computational fluid dynamics model is developed and simulated using ANSYS Fluent to evaluate the LCPV module temperature across 86 runs generated by RSM. Analysis of variance identifies the statistically significant factors and interactions. Subsequently, the study determines the optimal values of critical control factors to minimize the LCPV module temperature. The results reveal that the most significant factors affecting the LCPV module temperature are Vin, Tin, solar radiation level and CR, whereas wind speed and the converging channel outlet height represent less significance on the LCPV module temperature. Furthermore, at a wind speed of 0 m/s, solar radiation of 1100 W/m2 and CR of 3 suns, the minimum achievable module temperature of 316.191 K can be attained with Vin at 9.342 mm/s, Tin at 298.15 K and Hout at 3 mm.
