Abstract

Fotovoltaik hücrelerin enerji üretiminin sınırlı olması, bu cihazların en iyi çalışma koşullarında çalıştırılmasının önemli olduğunu gösterir. Ayrıca, güneş ışığının daha düşük olması ve hücre sıcaklığının daha yüksek olması, bunların tümü güç üretimini olumsuz yönde etkileyen değişkenlerdir. Bu makalede, alternatif ısıl kontrol tekniklerinden biri olan faz değişim malzemesi kurulumu ile hücre sıcaklığının azaltılması tartışılmaktadır. Fotovoltaik panel sıcaklığını düşürmek için böyle bir yöntemde geniş sıcaklık aralığının üstesinden gelmek için önerilen sistemde üç tip faz değişim malzemesi (RT15, RT35 ve SP25E2) birlikte kullanılır. Önerilen şema MATLAB kullanılarak simüle edilmiştir. Simülasyon sonuçları, yüksek sıcaklıklı PCM’nin etkisinin genel etki olduğunu göstermektedir. Sıcaklık PCM erime sıcaklığından daha düşük olduğunda PCM’nin kullanılması bir dezavantaj oluşturur. Bu dezavantaj, panelin sıcaklığının ortam sıcaklığından daha fazla artmasıdır.

Phase Change Material (PCM) Effect on Photovoltaic Performance of Solar Panels

Abstract

Photovoltaic (PV) cells energy production limitation leads to make its important to operate those panels in the best operating conditions. In addition, sunlight is lower and cell temperature is higher, all of which are variables that adversely affect power generation. The potential reduction of cell temperature by one of the alternative thermal control techniques, phase change material (PCM) installation is discussed in this article. Three types of PCM (RT15, RT35, and SP25E2) are used together in the proposed system to overcome wide temperature range, in such method to reduce the PV panel temperature. The proposed scheme is simulated using MATLAB. Simulation results shows that the effect of high temperature PCM is the overall effect. If the temperature is smaller than the PCM melting point, the use of PCM is disadvantage. This disadvantage is that the temperature of the panel increases more than the ambient temperature.
