AB  - Calculation of theamount of energy from the sun as the energy source of the world is veryimportant in terms of determining the efficiency of photovoltaic (PV) systems.At air mass zero solar spectral irradiance values have received a great deal ofattention in recent years and are given in the wavelength range 0.2-4.0µm. The amount of incoming sunlight canbe calculated with different mathematical models. In this study, a mathematicalmodelling using SPCTRL 2 program will be discussed. The model has manyvariables in determining the quantity of sunlight coming in the atmosphere.With this model, the amount of solar energy falling on any on spot on theEarth’s surface can be calculated and graphically modelled. In this study,direct, indirect and total (global) solar energy amounts coming from horizontaland sloping surfaces for Mugla were calculated depending on the wavelength.Horizontal and 30° inclined surfaces were calculated separately for winter,spring, summer and autumn seasons for Muğla Province. Asa result, the amount of solar radiance for Muğla province was determined bymathematical modelling and the general conditions for the establishment ofsuitable photovoltaic system were determined.

N2  - Güneş ışınımı, yeryüzüneelektromanyetik dalgalar şeklinde gelir. Güneşten gelen enerji miktarınınhesaplanması, fotovoltaik sistemlerin (PV) verimliliğinin belirlenmesiaçısından çok önemlidir. Fotovoltaik sistemler (PV) güneş enerjisini elektrikenerjisine dönüştürür. Bu dönüşümde, gelen güneş ışığı miktarı matematikselmodellerle ile hesaplanabilir. Son yıllarda büyük bir ilgi gören ve 0.2-4.0 µmdalga boyunda aralığında gelen spektral ışınım değeri hava kütlesiparametresine bağlı olarak hesaplanır. Bu çalışmada SPCTRL 2 programıkullanılarak matematiksel modelleme tartışılacaktır. Model, atmosferdeki güneşışığının miktarını belirlemede birçok değişkene sahiptir. Bu model ile herhangibir yüzeye düşen güneş enerjisi miktarı hesaplanır ve grafiksel olarakmodellenir. Çalışmamızda, Muğla ili için yatay ve eğimli yüzeylerinden gelendoğrudan, dolaylı ve toplam (küresel) güneş enerjisi miktarları dalga boyunabağlı olarak hesaplanmıştır. Muğla ili için kış, ilkbahar, yaz ve sonbaharmevsimlerinde yatay ve 30° eğimli yüzeyler ayrı ayrı hesaplanmaktadır. Burada,yüzeydeki radyasyon miktarlarının eğim açısı ve mevsimsel değişimleri incelenmiştir.Sonuç olarak, Muğla ili için güneş ışığı miktarı matematiksel modelleme ilebelirlenmiş ve uygun fotovoltaik sistemin kurulması için genel şartlarbelirlenmiştir.
