Modeling the Incident Solar Radiation of the City of N’Djamena (Chad)‎ by the Capderou Method

الملخص EN

Chad is like many African countries with no meteorological station at the moment to measure solar radiation throughout the country.

Thus, theoretical models are used to estimate incident solar radiation.

These models are established in correlation form.

Our objective was to present a model, which allows the determination of the solar component on two surfaces (horizontal and inclined).

This model allowed us to determine, over time, the component of global, direct, and diffuse solar radiation over a period that will cover the different seasons of the year.

The calculation is done according to Klein’s days over all the months of the year.

The hourly results of the global, direct, and diffuse radiation obtained for all the planes going from January to December are satisfactory compared to the results of the other authors quoted in the literature, which give the maximum and minimum values very close to theirs.

These results allowed us to validate the applicability of this model in a climate other than the desert climate.
