HOME / The effect of photovoltaic bracket on perforation - CAPTURED ENERGY SOLAR (PTY) LTDThe simulations of photovoltaic panels with aluminum and copper fins, both perforated and non-perforated, followed a rigorous methodology. For validation, the simulation results were compared with field data, yielding a mean absolute percentage error of 1.71%.
The temperature reduction observed in configurations with perforated fins was due to not only increased contact between the photovoltaic panel and the environment but also significant changes in the airflow dynamics that these perforations generated.
An analysis of the flow field showed that the perforations in the fins acted as disruptors of the laminar flow, allowing air to enter through the holes and generating vortices near the perforations.
Additionally, the perforations not only increased the contact surface with the air but also allowed for better convective flow through the fins. This improved ventilation around the heat sink, reducing heat accumulation points and promoting more homogeneous cooling.
