Abstract

In this work, a Monte Carlo model has been developed to simulate the collimated solar irradiation energy harvest in a louver of silica glass filled with water. The full solar spectrum is divided into a number of discrete bands, and the solar irradiation intensity on each band is distributed among a huge number of independent energy bundles. Band-averaged spectral properties of media (silica glass and water) are considered for each band. Through comparison of the results of different band division approaches and different energy bundle numbers, a practical band-division model is found, which is both computationally efficient and accurate. The incoming direction influence of solar irradiation on energy harvest is also investigated.
