Özet
Bu tez çalışmasında fotovoltaik güneş panellerinde ısı kaynaklı kayıpları düşürmek ve panel verimini yükseltmek için panelin arka yüzeyine sıkıştırılmış buhar yardımı ile soğutulmaya çalışılmıştır. Panellerin alt yüzey sıcaklıklarının sıkıştırılmış buhar ile soğutulması ile elde edilen değerleri ölçüp elde edilen verilerin karşılaştırılması yapılmıştır. Dış ortamın zamana bağlı sıcaklık değişimleri, güneş radyasyon değerleri ve ortam koşulları ölçülmüştür. Elde edilen bulguların analiz sonuçları panel üzerindeki verim hareketliliği incelenmiştir. Deney için üç adet 105W’lık PV panel kullanılmıştır. Modül üç panelin arka yüzeyine sarmal Şekilde montajlanan bakır boru içinde kompresör yardımıyla sıkıştırılmış R600 gazı ile soğutulmuştur. Modül iki panelin arka yüzeyine sadece su olması durumunda soğutulma yapılmıştır, modül bir panel ise ortam koşullarında bulunun bir panelin durumunu gözetlemek ve referans amaçlı olarak boş bırakılmıştır. Panel yüzeyine yerleştirilen üç farklı yüzey sıcaklıkları, ortam sıcaklığı ve giriş çıkış sıcaklıkları yapılmış ve zamana bağlı olarak oluşan güç, akım ve volt değerleri kaydedilmiştir. Sonuçlara göre deney düzeneğinde kullanılan tüm panellerin maksimum güç oranları önceden belirlenmiştir. Deney analizleri sonucunda soğutma düzeneği kurulan panel ve boş panelin verileriyle kıyaslanma yapıldığında soğutma yapılan panelde %5,73 güç üretimi fazlalığı bulunmuştur. Boşken panellerin güç üretimlerini kıyasladığımızda soğutulan panelin tüm gün boyunca ortalama olarak 0,5W daha az güç üretmiştir. Her üç panellinde aynı özelliklerine sahip olmasına rağmen oluşan farklılıklar deney sonucunda etkisini göstermiştir. Hesaplamalar sonucunda elektriksel verimin %9 iken, soğutulan panelde verim %7,9 olarak bulunmuştur. Yapılan deneyde soğutma yapılan modül üç, tüm gün ortalama sıcaklık değeri 33ºC’ de iken referans panelin ortalama sıcaklık değeri ise 40ºC’ de kalmıştır. Yapılan çalışmada panel 14ºC soğutulmuş ve bu sıcaklık farkı istenildiğinde daha da arttırılabilir Şekildedir. İdeal çalışma sıcaklığına 25ºC yakın olarak soğutma yapılan modül üçün panel arka yüzey sıcaklık aralığı olarak 30ºC’ ye sabit tutularak panelin üreteceği güç miktarı gözlemlenmiştir. Soğutma elemanı olan kompresör toplamda üç saat boyunca tükettiği enerji miktarı 0,319 kWh olarak bulunmuştur. Tüketmiş olduğu bu enerji miktarını karşılamak için 40W panel yeterli olacaktır.
Yapmış olduğumuz çalışmada soğutulan modül 3 no’lu panelin arka yüzeyini su ile tamamen kaplayıp tüm yüzey alanını eşit bir Şekilde soğutulmuştur. Soğutulan bu yüzey alanın eşit olmasından kaynaklı olarak diğer çalışmalara nazaran soğutma borularının temas ettiği alanların dışında tüm yüzey alanı eşit bir Şekilde soğutulmuştur. Böylelikle panel verimli yükseltilmiştir.
In this thesis, it has been tried to cool the photovoltaic solar panels with the help of compressed steam on the back surface of the panel in order to reduce the heat-related losses and increase the panel efficiency. The values obtained by cooling the lower surface temperatures of the panels with compressed steam were measured and the data obtained were compared. Time-dependent temperature changes of the outdoor environment, solar radiation values and ambient conditions were measured. The results of the analysis of the obtained findings were examined in terms of yield mobility on the panel. Three 105W PV panels were used for the experiment. The module is cooled by compressed R600 gas with the help of a compressor in a copper pipe mounted spirally on the back surface of the three panels. The back surface of the module two panels was cooled only in case of water, while a module panel was left blank for reference purposes and to monitor the status of a panel in ambient conditions. Three different surface temperatures, ambient temperature and input and output temperatures placed on the panel surface were made and the power, current and volt values that occurred depending on time were recorded. According to the results, the maximum power ratios of all panels used in the experimental setup were determined beforehand. As a result of the test analysis, when the data of the panel with the cooling device and the empty panel are compared, it was found that there is an excess of 5.73% power generation in the panel where the cooling is done. When we compare the power output of the empty panels, the cooled panel produced 0.5W less power on average throughout the day. Although all three panels have the same characteristics, the differences have shown their effect as a result of the experiment. As a result of the calculations, while the electrical efficiency was 9%, the efficiency in the cooled panel was 7.9%. In the experiment, the cooling module three, the average temperature of the whole day was 33ºC, while the average temperature of the reference panel remained at 40ºC. In the study, the panel was cooled to 14ºC and this temperature difference can be increased if desired. For the module, which is cooled at 25ºC close to the ideal operating temperature, the panel back surface temperature range is kept constant at 30ºC, and the amount of power produced by the panel is observed. The amount of energy consumed by the compressor, which is a cooling element, for three hours in total was found to be 0.319 kWh. A 40W panel will be sufficient to meet this amount of energy consumed. In our study, the cooled module completely covered the back surface of the panel no. 3 with water and cooled the entire surface area equally. Due to the fact that this cooled surface area is equal, compared to other studies, the entire surface area is cooled equally, except for the areas where the cooling pipes come into contact. Thus, the panel has been increased efficiently.
