Solarmeter Design for High Solar Radiation Measurement and Experimental Validation

Abstract

In this study, a solar meter was designed to measure high solar radiation. The solar meter uses the characteristic properties of a solar cell in order to measure solar radiation. In this way, measurements can be carried out without any limitations. The solar radiation equation was entered into the ARDUINO microcontroller in the solar meter, and the results were compared through another commercial solar meter. These results were entered into STATGRAPHIC software and three different functions with high regression values were obtained. These three functions were entered into the Arduino microcontroller and the experiments were repeated. According to the comparisons made using commercial device, R² values were determined as 0.944, 0.936, 0.938, and 0.986 for the first equation and for three different functions, respectively. Based on the values obtained, it has been determined that the solar meter can make highly accurate measurements and after the development of appropriate functions, it can be employed especially in high solar radiation concentrated systems.

Yüksek Güneş Işınımı Ölçümü için Solar Metre Tasarımı ve Deneysel Doğrulanması

Abstract

Yapılan bu çalışmada, yüksek güneş ışınımını ölçmek için bir solar metre tasarlanmıştır. Solar metre bir solar hücrenin karakteristik özelliklerini kullanarak güneş ışınımı ölçebilmektedir. Bu sayede herhangi bir sınırlama olmadan ölçüm yapılabilmektedir. Güneş ışınımı eşitlikleri ARDUINO mikro kontrol kartı aracılığıyla tasarlanan solar metreye girilmiştir ve başka bir ticari solar metre ile karşılaştırılmıştır. Bu sonuçlar STATGRAPICH programına işlenerek yüksek regresyon oranına sahip 3 farklı fonksiyon elde edilmiştir. Bu 3 fonksiyon tekrar ARDUINO mikro kontrol kartına girilerek deneyler tekrarlanmıştır. Ticari cihaz ile karşılaştırıldığında elde edilen R² değerleri birinci eşitlik için 0.944 ve 3 farklı fonksiyon içinse sırasıyla 0.936, 0.939 ve 0.986 olarak tespit edilmiştir. Elde edilen değerlere dayanarak, tasarlanan solar metrenin oldukça hassas ölçümler yapabileceği ve uygun fonksiyonların geliştirilmesinden sonra, özellikle yüksek güneş radyasyonlu yoğunlaştırıcılı sistemlerde kullanılabileceği belirlenmiştir.
