Improve The Electrical Output Power of Photovoltiac Modules by Using Different forms of pipes

Abstract

The Renewable energy especially photovoltaic panels (PV) is very important issue to produce the electricity at MENA region (The Middle East and North Africa). A continouse high performance for electrical output helps the outback area for home lighting or heating in winter season. Therefore, to improve a fixed photovoltaic performance by using different pipes cooling techniques (serpentine, & pancake shapes) attached on the backside of PV module. The paper reported the electrical performance (electrical output power) of a photovoltaic module by using water as a cooling fluid. Besides that, the thermal behavior analysis introduced by the difference temperatures of cooling water and the module temperature. The thermal results exposed that, for the PV module temperature with serpentine and pancake cooling pipes decreased about 11.6 % and 16.59 % compared with (STC) Standard Temperature Condition (PV without cooling). In addition, the differance water temperature increased about 3.8 % and 5.8 % for two differant forms. That leads to enhancement in the module daily output power up to 8.9 % by using the pancake compared with serpentine cooling shape.
