Quality issues for photovoltaic-sound barriers

Photovoltaic sound barriers derive their peculiarity from the primary function to reduce noise emission from high-traffic transportation infrastructures. They also gather some characteristics typical of large PV plants as well as several features of building integrated PV. Quality characteristics of PV sound barriers are not only set by electrical and acoustical functionality, but it also depends on safety, ease of maintenance, visual impact. The definition of widely accepted quality standards for PV sound barriers is important for designers and builders. It is particularly relevant for customers too, who could find in the standards a support for definition of the technical specifications to be used for different activities related to commissioning of the plants and for acceptance tests.
