The plate has a structure formed by photovoltaic coatings, varnishes or directly from solar cells for production of electric energy. The plate is hung at conducting cables that feed power into a power line. The plate is manually or automatically adjustable according to a solar radiation angle, synchronized with a plate-visual cover, and mounted at walls. A portion of the electric energy is provided as an energy source for adjusting the plate. The plate is combined as an advertising surface and an advertising message in coordination with an advertising slogan and a solar altitude. |
