Abstract

Photovoltaic systems, which is one of the subjects that many developed countries are working on, are used to obtain electrical energy from solar energy. Photovoltaic systems have emerged as one of the most reliable and affordable alternatives to meet energy needs. In case of meeting this energy need, examining the conditions such as partial shading depending on the time is vital for meeting the energy. The shading situation causes the power obtained to decrease significantly. As the shading rate increases, the efficiency decreases. Therefore, for different conditions, the effect of the shading situation on the power obtained must be investigated. This study was done in a laboratory environment by using solar simulator. The distance between the artificial light source and the panel is set at 0.8 m and 1.4 m, and the angle is 0 °, 20 ° and 40 °. In case of shading to the all cells and shading to 1/36, 2/36 cells, in terms of panel characteristic and change of maximum power are compared. The results showed that the maximum power obtained decreases as the distance and angle between the artificial light source and the panel increases.

Abstract

Birçok gelişmiş ülkenin üzerinde çalışmalar yaptığı konulardan biri olan fotovoltaik sistemler, güneş enerjisinden elektrik enerjisi elde etmek için kullanılır. Fotovoltaik sistemler enerji ihtiyacını karşılamak için en güvenilir ve en hesaplı alternatiflerden biri olarak ortaya çıkmıştır. Bu enerji ihtiyacı karşılama durumunda zamana bağlı olarak kısmi gölgelenme gibi durumların incelenmesi, enerjiyi karşılama açısından hayati önem taşımaktadır. Gölgeleme durumu, elde edilen gücün önemli ölçüde azalmasına neden olmaktadır. Gölgeleme oranı arttıkça verim azalmaktadır. Dolayısıyla farklı şartlar için, gölgeleme durumunun elde edilen güç üzerindeki etkisinin araştırılması gerekmektedir. Bu çalışma laboratuvar ortamında solar simülatör kullanılarak yapılmıştır. Yapay ışık kaynağı ve panel arasındaki uzaklık 0.8 m ve 1.4 m, açı ise 0°, 20° ve 40° olacak şekilde ayarlanmıştır. Hücrelerde gölgeleme olmaması durumu ile 1/36 ve 2/36 gölgeleme durumu, panel karakteristiği ve maksimum gücün değişimi açısından karşılaştırılmıştır. Sonuçlar yapay ışık kaynağı ve panel arasındaki mesafe ve açı arttıkça elde edilen maksimum gücün azaldığını göstermiştir.
