Solar Radiation Modeling Using M5 Model Tree

Abstract

The study investigates the ability of M5 model tree in modeling monthly solar
radiation. Monthly data of maximum and minimum air temperatures, wind
speed, relative humidity and solar radiation from Antalya, Turkey were used in
the application. The effect of each climatic parameter on solar radiation is investigated. Periodic models are also developed to see the effect of periodicity
component on models’ accuracy. It was found that using periodicity as input to
the applied models significantly increases their accuracy in modeling monthly
solar radiation.
