Özet
In design of solar energy systems, solar radiation data's accuracy is very important. When we survey present studies in literature, because of the expensiveness of system installations that measure solar radiation and sunshine duration, it appears that relations are developed for the area where there will be study by using measured values at the nearest area to chosen area. The most known and commonly used of these formulas is Angstrom formula. Received instantaneous, hourly and daily solar radiation values in the earth surface are measured in some meteorological stations. Furthermore, at some of our areas these measurements still can not be performed. Received instantaneous, hourly and daily solar radiation values in the earth surface can be measured with the help of relations which are developed for solar energy applications at these areas. In this study, total solar radiation change measured by DMI (State Meteorological Services) for the estimation of monthly average daily solar radiation in Konya province has been researched. Based on the measured values, statistical analysis of the calculation methods that are used in monthly average total solar radiation and sunshine duration has been done. Root mean-square error (RMSE), for performance assessment of equation, has been compared by mean bias error (MBE) and t-statistic methods. By comparing measured and obtained values from equations, the right equation has been found.
