Shadovoltaic photovoltaic solar shading

Colt Shadovoltaic is an external fixed or moveable photovoltaic solar shading louvre system, designed to reduce heat gains and glare whilst maximising the use of natural daylight, and generating electricity by means of integrated photovoltaic (PV) cells.

PV cells are integrated into the glass of the shading louvres, either by attaching them to the reverse side of the glass panels or by laminating them between two sheets of glass.

Like Shadoglass, Shadovoltaic may be installed either vertically or horizontally in front of the façade or on the roof. It can be either fixed or controllable.

System types (for sizes, see bottom of this page)

  • Shadovoltaic LS-1 is centrally pivoted, intended for wide spans, and incorporates a central aluminium torsion tube incorporating the louvre brackets along the length of the louvre for additional support.
  • Shadovoltaic LS-2 is primarily intended for small spans or where frequent anchor points are available. It provides minimum obstruction to the glass area, thereby maximizing daylight and enhancing the view to the outside.
  • Shadovoltaic LS-3 is centrally pivoted, intended for very wide spans. An aluminium clamping system is fixed along to the short edges of the louvre blades.
  • Shadovoltaic LS-4 is a back hinged system with hidden control mechanisms integrated within the main vertical supports. This enables a seamless continuous appearance when viewed from the outside, since the supports are installed to the back of the louvres
