Modeling the solar irradiation on flat plate collectors augmented with planar reflectors

摘要: An analytical model has been developed and used to determine solar irradiation on flat collectors augmented with planar reflectors. The uses measured insolation data from the NREL National Solar Radiation Data Base. In addition accounts for direct reflected components of beam, diffuse ground insolation, considers finite length systems, shading collector by reflector, different configurations reflector relative collector. Thus represents an extension refinement many previous models. Computer simulations have carried out over time spans assess effects including these features. general, reflectors enhances radiation received Reflected beam is major contributor enhancement, although sky can be significant in instances. To optimize effectively design system respect selecting tilt angles specifying a reflector-above or below-collector configuration requires proper modeling energy system. Finite analysis enables optimization size that presented basis tool optimizing variety reflector-enhanced collection systems.
