In this work, we investigate the effect of enhancing the heat loss from PV cell by way of altering the morphology of the assembly. The work is done on 9-cell mini-module. Specifically, the gaps between the cells of the module, the angle of the cells, and the plane in which individual cells are installed, are studied numerically used the finite element method. The modelling results is first validated using an existing physical module installed in the desert of Kuwait with data on wind, ambient temperature, radiation and power output taken every 30 seconds. Subsequent optimization is done using the same thermal and hydrodynamic conditions but with altered geometrical model. Preliminary results show that altering the structure of the flow around the module in a way that disturbs the boundary layer enhances the heat flow from the module. Results also show that these changes, which are investigated parametrically, seem to have an optimum. The maximum temperature of the module can be reduced by a good percentage simply by changing the shape of the module. These modifications at the design stages translate directly into higher efficiency of the PV module as a whole during the operation stage.
