Tek ve Çift Yüzeyli Fotovoltaik Sistemlerde Yüzey Temizliğinin ve Panel Yerleşim Açılarının Enerji Üretim Performansına Etkisi

Öz

Son yıllarda fotovoltaik (FV) enerji üretiminde teknolojik gelişmeler hızla ilerlemektedir. Bu gelişmeler, modül hücre sayısının artırılması, gelişmiş cam teknolojilerinin uygulanması ve çift yüzeyli cam kullanılarak üretilen FV modüllerinin geliştirilmesi gibi önemli yenilikleri içermektedir. Ayrıca, bu ilerlemeler, FV modüllerinin enerji üretim verimliliğini artırmaya yönelik çeşitli saha uygulamalarının önünü açmıştır. Bu tür uygulamalar, kurulum maliyetinin amortisman süresini kısaltmanın yanı sıra FV modüllerinin verimliliğini de artırmaktadır. Özellikle çift yüzeyli modüller, her iki yüzeyden de güneş ışığını absorbe ederek enerji üretiminde önemli bir artış sağlamaktadır. Bu çalışmada, Ankara ili Polatlı ilçesinde belirlenen koordinatlarda, PVSyst ve PV*SOL benzetim programları kullanılarak tasarlanan 9.639,630 kWp üretim kapasiteli bir güneş enerjisi santrali analiz edilmektedir. Bu araştırmanın temel amacı, tek yüzeyli ve çift yüzeyli FV panellerin eğim açılarındaki değişimlerin enerji üretimine etkilerini incelemek ve tespit edilen optimum açı değerleri ile temizlik stratejilerini belirlemektir. Böylece, santralin enerji üretim kapasitesini en üst düzeye çıkarırken aynı zamanda işletme maliyetlerini düşürmek hedeflenmektedir. Bu araştırmanın bulguları, güneş enerjisi yatırımlarının hem yerel hem de ulusal düzeyde daha verimli hale getirilmesine önemli bir katkı sağlayacaktır. Ayrıca, güneş enerjisi sektörüne optimal sistem konfigürasyonları ve bakım uygulamaları konusunda kritik bilgiler sunarak sektöre önemli bir kaynak oluşturacaktır.

The Impact of Surface Cleaning and Panel Placement Angles on Energy Production Performance in Monofacial and Bifacial Photovoltaic Systems

Öz

In recent years, technological advancements in photovoltaic (PV) energy production have progressed rapidly. These developments include significant innovations such as increasing the number of module cells, implementing advanced glass technologies, and producing PV modules with double-sided glass. Furthermore, these advancements have facilitated various field applications aimed at enhancing the energy production efficiency of PV modules. Such applications not only shorten the amortization period of installation costs but also improve PV module efficiency. Bifacial modules, in particular, offer a notable increase in energy generation by capturing sunlight from both surfaces. In this study, a solar power plant with a production capacity of 9.639,630 kWp, designed using PVSyst and PV*SOL simulation programs at specified coordinates in the Polatlı district of Ankara Province, is analyzed. The primary objective of this research is to investigate the effects of variations in the tilt angles of unidirectional and bidirectional PV panels on energy production and to determine the optimal angles and cleaning strategies. By doing so, the study aims to maximize the power plant’s energy generation capacity while simultaneously reducing operational costs. The findings of this research will serve as a valuable resource for improving the efficiency of solar energy investments both locally and nationally. Moreover, they will contribute significantly to the solar energy sector by providing insights into optimal system configurations and maintenance practices.
