Landscape impacts of photovoltaic plants on the ground: a case-study through the application of rendering techniques

摘要

In recent years, among the renewable energy sources, the photovoltaic plants (PVs) along with wind power plants experienced a remarkable growth rate. If the visual impact assessment of wind turbines is already object of an extensive scientific literature, the effects of PVs on landscape have been few analyzed. A real case-study has is proposed where, with appropriate rendering techniques, a three dimensional simulation of the ground with insertion of PVs pictures has been compared, at different spatial scales, to the bare landscape. In particular, the work is based on the analysis of two parameters affecting negatively the landscape: the visibility and the colour of the plants. The visibility, accompanied by an opportune three-dimensional design stage, and the colour, with the appropriate chromatism of the panels, are mitigation measures for the reduction of the visual impact, and they could play a key role in achieving a virtuous landscape compatibility.
