CHAPTER 6<br />
RESULTS<br />
6.1. Results for Global Solar Radiation<br />
In the analysis, the data measured at the IZTECH Campus between 2005 <strong>and</strong><br />
2007 were used. The equations mentioned in Chapter 1 were calculated in order to<br />
estimate the total monthly-average daily global <strong>radiation</strong>.<br />
Starting from Eq. (1.5), δ values were calculated <strong>and</strong> varied between -23.44°<br />
<strong>and</strong> 23.44°. In order to estimate Sₒ, Eqs. (1.6) <strong>and</strong> (1.2) were used respectively. In Table<br />
3, Sₒ can be seen for 3-yr period.<br />

Table 4 showed the monthly average daily bright sunshine hours for Izmir,<br />
Turkey that was derived from measured data in the Solar-Meteorological Station <strong>of</strong><br />
Solar Energy Institute in Ege University.<br />
