Su Soğutmalı Fotovoltaik Sistemin Performans Analizi

Bu çalışma ile FV panellerin çalışma sıcaklıklarını harici soğutma düzenekleri ile azaltmak suretiyle verimliliklerinin artırılması Osmaniye yöresi için gerçeklenmiştir. Güneş enerjisinden elektrik üretirken panelin sıcaklığı artmakta ve bu da panel verimini azaltmaktadır. Fotovoltaik(FV) panelin ısısı, panelin arka yüzeyine yerleştirilen bakır plaka üzerine yerleştirilmiş bakır boru sistemi ile panel ısısının düşürülmesi böylelikle verimliliğin artırılması sağlanmıştır. Ayrıca, soğutmalı ve soğutmasız panel ısıl ve elektriksel verimliliklerinin Osmaniye bölgesi şartlarında karşılaştırılması yapılmıştır. Her iki panel için aynı anda güneş ışınımı, hava / FV panel sıcaklığı, güç, akım ve gerilim gibi FV panel karakteristik değerleri ölçülmüştür. FV panellerin termal ve elektriksel enerji performansı karşılaştırmalı olarak analiz edilmiştir. Genel verim için, su soğutmalı FV sisteminin % 5.9 ile soğutmasız FV panelinden daha iyi olduğu gözlenmiştir.

Performance Analysis of Water Cooled Photovoltaic Power Systems

The aim of this study consists of two stages. The first purpose is to increase the efficiency of photovoltaic (PV) panels by reducing their operating temperatures with external cooling devices to generate electricity from solar energy. The temperature of the photovoltaic panel (PV) is lowered by circulating water through the copper pipe system placed on the copper plate which is mounted on the rear surface of the panel, thus increasing the efficiency of the panel. The second objective is to compare the thermal and electrical efficiency of the refrigerated and normal panels under Osmaniye region conditions. PV panel characteristic values such as solar radiation, air/PV panel temperature, power, current and voltage were measured for both panels simultaneously. The thermal and electrical energy performance of PV panels was analyzed comparatively. For overall efficiency, it was observed that the water-cooled PV system was better than the normal PV panel with 5,9%.
