The initial installation covered 950 m² and during the latter part of 2017 the solar panel installation was increased to a total of 1155 m2. Villiera currently produces a large portion of its own energy requirements from this completely sustainable source and the increased capacity provides sufficient energy to power pumps for the dams. . In addition, the cellar receives its lighting requirements through solar domes which were installed to further reduce Villiera’s reliance on carbon-based energy production.
