ABSTRACT: The
global sustainability plan for future development relies on solar radiation
which is the main source of renewable energy. Thus, this work studies the
performance of six models to estimate global solar radiation on a horizontal
surface for the Abeche site in Chad. The data used in this work were collected
at the General Directorate of National Meteorology of Chad. The reliability and
accuracy of different models for estimating global solar radiation were
validated by statistical indicators to identify the most accurate model. The
results show that among all the models, the Sabbagh model has the best
performance in estimating the global solar radiation. The average is 6.354
kWh/m2 with an average of -3.704%. This model is validated against
NASA data which is widely used.
