In this study, PV panels; By calculating the instantaneous total radiation values; The monthly, seasonal and annual optimum tilt angles were found, and the effects of parameters such as environmental temperature and wind speed on panel efficiency and panel electrical power were investigated. In the different method of optimum tilt angle calculation used in this study; The sum of instantaneous total radiation values coming on the titled surface during the day was calculated and this calculation was made separately for 365 days. Thus, daily, monthly, seasonal and annual radiation calculations were made and optimum tilt angle values that maximize these radiation values were obtained. The results obtained were found to be 3-5 degrees different from the optimum tilt angle values obtained by using monthly average radiation values. These calculations were made for 6 different provinces and optimum tilt angles were found. In case the PV panels are placed with the optimum tilt angle, the instantaneous radiation on the panel, instantaneous panel efficiencies and generated electrical power values were calculated. In these calculations, the effect of environmental temperature and wind speed is also taken into account.
Bu çalışmada PV panellerinin; anlık ışınım şiddeti değerlerinin hesabıyla; aylık, mevsimlik ve yıllık optimum eğim açıları bulunmuş, çevre sıcaklığı ve rüzgar hızı gibi parametrelerin panel verimleri ve panel elektrik gücü üzerinde etkileri incelenmiştir. Bu çalışmada kullanılan farklı optimum eğim açısı hesaplama yönteminde; eğik düzlem üzerine gelen anlık ışınım değerlerinin gün boyunca toplamı hesaplanmış ve bu hesaplama 365 gün için ayrı ayrı yapılmıştır. Böylece günlük, aylık, mevsimlik ve yıllık ışınım hesaplamaları yapılarak bu ışınım değerlerini maksimum yapan optimum açı değerleri elde edilmiştir. Elde edilen sonuçlar, aylık ortalama günlük ışınım değerleri kullanılarak bulunan optimum eğim açısı değerlerinden 3-5 derece daha farklı bulunmuştur. Bu hesaplamalar 6 farklı il için yapılarak optimum eğim açıları bulunmuş, PV panellerinin optimum eğim açısı ile yerleştirilmesi durumunda panel üzerine gelen anlık ışınım, anlık panel verimleri ve üretilen elektrik gücü değerleri hesaplanmıştır. Bu hesaplamalarda çevre sıcaklığı ve rüzgar hızının etkisi de dikkate alınmıştır.
