the airflow energy modelling in a spiral absorber in static and dynamic situations

The absorption of sunlight causes solar panels to heat up, and the resulting temperature plays a crucial role in determining the amount of output voltage. in this study, a novel spiral geometry was developed behind the tedlar layer of photovoltaic panels (pvs) to regulate the dissipation of heat by air. dynamic and static numerical modelling was conducted using open-source matlab software. the first step involved determining and simultaneously solving mathematical equations to obtain the desired geometry. a comparison of static modelling revealed that in identical environmental conditions, the electrical efficiency of the system (temperature of the cell) was approximately 7.5% and 10% (58 ºc and 53 ºc), without and with the use of a heat absorber, respectively. in the subsequent phase, a variable speed fan with a maximum power of 2 watts was employed behind the panel to cool the system. dynamic modelling showed that the system efficiency and cell temperature were 7.4% and 58.5 ºc, respectively. by using a spiral thermal absorber, under similar environmental conditions, the cell temperature decreased to 54 ºc, and the system efficiency was improved to 9.2%. according to dynamic modelling, a reduction of 8% in panel temperature could be achieved.
