Increasing the acceptance of façade-integrated PV (photo voltaic) is of great interest. Architects will often be opposed to integrate PV in their design based on visual aspects of available PV products. The project described in this paper addresses this topic by bringing together a known technology - sandblasting of glazing surfaces – and standard, off the shelf PV-modules. The final goal of the project is to provide architects with a catalogue of possible glass-surface visual design elements. Each design element will be given with approximate reduction values for radiation transmission. Thus, ideally a design that is desired can be estimated in regard to PV-performance-values to be expected. A first set of design elements is shown and corresponding radiation transmission reduction values are given. The design elements are differently sandblasted and coloured glass surfaces with various grades of opacity. The reduction in transmission as compared to a standard low iron glass is found to be in the range of 10 to 80 %, mainly depending on the glass colour. Some examples for possible designs are shown. The relative loss in performance compared to an untreated PV-module of the same type is found to be of the same order of magnitude as the accepted spread in module power according to manufacturer data. This is viewed to be an encouraging result.
