Analytical Modeling and Optimization of a Heat Sink Design for Passive Cooling of Solar PV Panel

High temperature is the primary challenge in development of solar photovoltaic (PV) systems an arid climate. A rise diminishes performance PV and shortens their lifespan. The goal this manuscript to develop analytical model predict panels under a passive cooling system for environment. Taking into consideration link between panel its conversion efficiency, Kirchhoff’s Ohm’s laws complex circuit were applied calculate heat flux system, hence obtain temperatures each layer system. Closed-form expressions temperature, output power, efficiency deduced presented as functions irradiance, ambient emissivity, wind velocity, tilt angle, dimensions fins. Comparison results literature those predicted by developed validated model. Moreover, length fins required safe thermal operation harsh desert environment also obtained from analysis. Furthermore, effect using such on was verified real conditions Dammam city during summer winter seasons. showed that optimized sink could raise power 8.7% 6.5% winter.
