Abstract—Solar energy has come into prominence due to its
sustainability, emission-free and ease of use considering the
harmful nature of fossil resources in recent years. Accurate
information on global radiation is essential to achieve the goal of
planning and projection of a solar power system. Global solar
radiation measurements provided by meteorology lack of
reliability and some of the data are missing. At this point, global
solar radiation estimation has an important role in designing
energy systems that are based on solar energy. In this study, six
different global radiation models are considered to estimate the
monthly average hourly global radiation from the daily value in
Çanakkale, which is located in the northwest of Turkey. The
models are validated with hourly global radiation measurements
provided by the Turkish State Meteorological Service. Based on
the analysis of mean absolute bias error (MABE), root mean
square error (RMSE), mean bias error (MBE) and t-statistical
test, accuracy of the existing models is obtained. The results
indicate that the Collares - Pereira and Rabl model modified by
Gueymard (CPRG) is the most accurate one, and this model is
proposed to obtain the hourly global radiation averaged over the
months in elsewhere that has the similar climate with the
northwest of Turkey.
