Abstract

Artan enerji ihtiyacı arzına karşı oluşturulan önlemlerin en başında enerji verimliliği gelmektedir. Dahası küresel iklim krizi, çevrenin korunması ve ekonomik kazancın iyileştirilmesi de ancak aktif enerjili sistemlerin optimize edilmesiyle mümkün olmaktadır. Bu amaçla, güneş enerjili sistemlerin verimini en üst düzeye çıkarılmasında güneş panellerinin uygun eğim açılarına ve doğru konumlara sahip olması bir gerekliliktir. Bu çalışmada güneş enerjisi potansiyeli Türkiye ortalamasının üstündeki Van ili (43°38’ E-38°50’ N) için aylara göre optimum panel açısı güney konumuna bakan yöne göre belirlenmiştir. Yıllık panel eğim açısı 30.540 olduğu tespit edilmiş ve panel açılarının aylık değişimi durumunda yıllık verim yatay düzleme göre %14 ‘e kadar artarak yıllık ortalama 5090 Wh/m2-day ışınım değerine ulaşmaktadır. Bölgenin sahip olduğu enleme özgü optimum açı değerinin tahmine yönelik 4 farklı değişkenden 8 farklı matematiksel model geliştirilmiştir. Bu modellerin istatiksel olarak belirlilik katsayısı (R2) aralığı 0.9068 ile 0.9964 aralığında değişkenlik göstermektedir. Bu bulgular neticesinde uygulanabilirliğini ve güvenilirliğini kanıtlanan regresyon modeli aynı enlemdeki farklı koordinatlardaki konumlara örnek teşkil edebilir. Ayrıca sonuçlar, önerilen modelin mühendislik tasarımı, eko-enerji analizi ve optimum tasarım süreçlerinde kullanım açısından akademik ve sanayicilere örnek teşkil etmektedir.

A Regression Model for Finding Optimal Solar Panel Inclination Angles

Abstract

Energy efficiency is at the top of the measures created against the ever-increasing energy need for supply. Moreover, the global climate crisis, the protection of the environment, and the improvement of the economy are only possible by optimizing active energy systems. For this purpose, it is a requirement that the solar panels have the appropriate tilt angles and correct positions in order to maximize the efficiency of solar energy systems. In this study, for the province of Van (43°38’ N-38°50’ E), whose solar energy potential is higher than the average of Turkey, the optimum solar panel angle according to the months of the year was determined for the south-facing solar panels. It has been determined that the annual panel inclination angle is 30.540 and in the case of monthly change of panel angles, the annual yield increases up to 14% compared to the horizontal plane, reaching an average annual radiation value of 5090 Wh/m2-day. 8 different mathematical models have been developed from 4 different variables for estimating the optimum angle value specific to the latitude of the region. The statistical coefficient of certainty (R2) range of these models varies between 0.9068 and 0.9964. As a result of these findings, the regression model, whose applicability and reliability have been proven, can serve as examples of locations at different coordinates in the same latitude. Furthermore, the results set an example for academics and industrialists in terms of the proposed model's engineering design, eco-energy analysis, and use in optimal design processes.
