Prediction of total solar irradiance on tilted greenhouse surfaces CIGR Journal
Ronoh, Erick K..
Solar radiation is the driving force for the surface energy balance in buildings such as greenhouses.  The greenhouses are generally tilted towards the sun in order to maximize the solar irradiance on the surfaces.  Precise computation of the solar radiation received on these surfaces assumes an important role in the energy simulation.  It is practical to calculate the total solar irradiance on the tilted surfaces based on the solar global and diffuse radiation intensities on horizontal surfaces.  In this work, a south-facing thermal box inclined at 26.5° from the horizontal was used for solar radiation measurements.  Additionally, the recorded solar radiation data were retrieved for the study location and used to develop an empirical correlation.  The...
