The uniformity of the radiation flux profile along the focal line of a linear parabolic concentrator is typically dependent on factors such as the mirror shape accuracy, gaps between mirrors and shading due to receiver supports. For a photovoltaic trough concentrator, small regions of low radiation flux can have a large impact on the entire system performance. Radiation flux profiles have been ...

In this talk, starting with some earlier results, we propose and analyze an alternate approach of optimal L2error estimates for semidiscrete Galerkin approximations to a second order linear parabolic initial and boundary value problem with rough initial data. Our analysis is based on energy arguments without using parabolic duality. Further, it follows the spirit of the proof technique used for...
