  1. Photovoltaic Panel Efficiency Optimization Using Forced Convection Cooling In Porous Media Enclosure Master’s Degree Project Bradley Fontenault

  2. Problem Definition • Photovoltaic cells lose efficiency as operating temperature increases (~-0.54%/deg. C for single crystalline Si cell) • The objective of this study is to investigate a method of cooling PV panels as to increase their electrical output efficiencies

  3. Various Methods Have Been Explored to Cool PV Cells to Improve Efficiency • Various methods have been developed to cool PV Cells • Heat extracted from cells is typically used for other purposes (heat potable water, radiant floor heating, heat swimming pool water, operate a heat pump, etc.) while increasing electrical efficiency of cells • Bakker – geothermally cooled cells, coolant water used for potable water • Chen – used refrigerant R134a to cool cells, heat energy used in heat pump

  4. Project Objective • Pump water through porous media in enclosure on back of PV panel to cool panel • Will analyze various water flow rates • Will analyze various porous materials • Will analyze various porosity and permeability parameters • Calculate thermal energy extracted and temperature decrease of solar cell exposed to constant sun irradiance • Can determine increase is solar panel efficiency using public solar panel efficiency data • Yang et. al.
