Greenagenda.gr — the first energy autonomous greenhouse in the country

Transparent solar panels seen from below

29.09.2020

Greenagenda.gr reported on the first greenhouse in the country covered with solar glass, which produces and consumes clean energy from sunlight.

The installation was developed at the facilities of a winery in Agios Pavlos, Halkidiki. The article describes the ecological construction of the greenhouse and the way the glazing both shelters the vines and carries the photovoltaic layer.

More coverage is collected under press; the technology itself is described on the project page.

How the glass is built

The panel is a laminate: an active layer carried between sheets of architectural glass, sealed at the edges and mounted in the same profiles a greenhouse or facade already uses. Nothing about the installation asks the builder to learn a new trade, which matters more for adoption than any laboratory figure.

Transparency is the design parameter that everything else follows from. A pane that passes most of the visible light leaves the crop unaffected but generates modestly; one that passes less produces more current and starts to shade. The specification is chosen per project, against the crop and the latitude it will grow at.
