Bu
çalışmada, fotovoltaik modüllerin iç ve dış ortamda elde edilen sıcaklık
katsayılarının karşılaştırılması için yeni bir yöntem ortaya konmuştur.
Fotovoltaik modüllerin/örgülerin gerçek performanslarının doğru bir şekilde
simüle edilebilmesi için doğru sıcaklık katsayılarının kullanılması oldukça
önemlidir. Bu yüzden, gerçek performansın simülasyonunda hangi tip sıcaklık
katsayılarının (iç veya dış) daha doğru sonuçlar vereceği belirlenmelidir. Kısa
devre akımı, açık devre gerilimi, 
maksimum çıkış gücü ve üretilen enerji gerçek performans parametreleri
olarak kabul edilmişlerdir. Bu çalışmada ortaya konan yeni yöntem, gerçek
performansı iç ve dış ortam sıcaklık katsayıları için simüle etmekte ve hangi
tip sıcaklık katsayılarının daha doğru olduğunu belirleyebilmek için dış
ortamda ölçülen gerçek performansla karşılaştırmaktadır.

New Method to Compare Indoor and Outdoor Temperature Coefficients of Photovoltaic Modules

Öz

In this study, a new method is presented to compare the indoor and
outdoor temperature coefficients of photovoltaic module. Precise input of
temperature coefficients introduced in the simulation is very essential to
obtain accurate results about the actual performance of photovoltaic
module/array. Thus, it is important to specify which type (indoor or outdoor)
of the temperature coefficient is more accurate in simulating the actual
performance. The short circuit current, the open circuit voltage, the output
peak power and produced energy are considered as actual performance indexes.
New method proposed in this study, simulates the actual performance for both
indoor and outdoor temperature coefficients and compares with actual
performance measured at field to decide which type of temperature coefficient
is more accurate.
