Today, the search for green energy to meet the never-ending demand for energy, rather than depleting conventional resources, is still ongoing. However, the steady increase in the contribution of solar energy to electricity generation over the last three decades has put solar energy on the agenda as a viable option. However, the power generated by photovoltaic (PV) systems is low due to low conversion efficiency. Therefore, some critical analyses need to be carried out on the factors that improve the efficiency of the photovoltaic system. The output power generated by a photovoltaic panel depends on many factors. Some of these factors are type of photovoltaic material, intensity of received solar radiation, panel temperature, clouds and other shading effects, inverter efficiency, dust pollution factor, panel orientation and tilt angle, weather conditions, geographical location, cable thickness. In the article, solar radiation, shading and tilt angle factors, which significantly affect the performance of photovoltaic systems, will be experimentally investigated.

FOTOVOLTAİK SİSTEMLERDE VERİMİ ETKİLEYEN PARAMETRELERİN DENEYSEL OLARAK İNCELENMESİ

Öz

Günümüzde, tükenmekte olan konvansiyonel kaynakların yerine sonsuz enerji talebini karşılayacak yeşil enerji arayışı hala devam etmektedir. Ancak son otuz yıldır güneş enerjisinin elektrik enerjisi üretimine katkısındaki istikrarlı büyüme, güneş enerjisini uygulanabilir bir seçenek olarak gündeme getirmektedir. Ancak, düşük dönüşüm verimliliği nedeniyle fotovoltaik (PV) sistemlerden elde edilen güç düşüktür. Bu nedenle, güneş PV sisteminin verimliliğini artıran faktörler üzerinde bazı kritik analizlerin yapılması gerekmektedir. Bir fotovoltaik panel tarafından üretilen çıkış gücü birçok faktöre bağlıdır. Bu faktörlerden bazıları, fotovoltaik malzemesinin türü, alınan güneş ışınımının yoğunluğu, panel sıcaklığı, bulut ve diğer gölgeleme etkileri, invertör verimliliği, toz-kirlilik faktörü, panel oryantasyonu ve eğim açısı, hava koşulları, coğrafi konum, kablo kalınlığıdır. Çalışmada, fotovoltaik sistemlerinin performansını önemli ölçüde etkileyen güneş ışınımı, gölgeleme, eğim açısı faktörleri deneysel olarak incelenmiştir.
