Modeling Solar Energy Transfer through Roof Material in Africa Sub-Saharan Regions

Table 2

Ambient temperature (𝑇_a), solar irradiance (SR), wind speed (V) and the galvanized ion sheet roof room temperature (𝑇_r), the roof inner wall temperature measured (𝑇_pim), and simulated (𝑇_pis) and energy flux entering the room were reported.
