Résumé

A Monte Carlo model is developed to simulate the solar radiation transfer through a water-filled prismatic louver for solar energy harvesting. Solar irradiation includes both collimated and diffuse components. The full solar spectrum is divided into different discrete bands for better treatment of the spectral properties of solar irradiation and glass and water absorption. In particular, we considered 1 full band, 3, 7, 10, 20 and 40 bands, respectively. The influences of band division, photon number, and element number on solar energy absorption in the louver are discussed. The energy absorption efficiency utilizing different ratios of collimated and diffuse components is analyzed. For the trade-off of balance between the computational efficiency and accuracy, the 7-band model is generally adopted in most calculations. The effect of mesh division was found to be less sensitive for analyzing the overall solar energy absorption in the louver.
