Shadovoltaic photovoltaic solar shading louvre system

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.

Features and benefits:

  • A wide range of louvres – Shadovoltaic louvres are available in various colours, surface finishes and coatings to meet specific design requirements. The type of glass, frit, film or cells can be varied. The louvre spans depends on structural considerations and the kind of louvre blade selected.
  • A wide range of carrier systems.
  • Flexible controls - Shadovoltaic shading systems can be operated by linear actuators that have the capability to operate complete facades. A series of louvres are attached to a system of levers and push rods which link them to a control system. The louvres may be fixed at any angle and can rotate under motorised control within a range of up to 90⁰.
  • Robust - Shadovoltaic is made from high grade aluminium and stainless steel. The system is designed to compensate for thermal expansion.
  • Potential to reduce installation time – Shadovoltaic can be provided in modular pre-assembled form.

Product Options

Shadovoltaic has four basic carrier systems:

- Shadovoltaic LS-1:

  • 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:

  • 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

  • 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:

  • 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.

Control method:

There are two control methods available:

  • ICS 4-Link: Provides accurate solar control and is particularly suited to larger projects. The system continually calculates the position of the sun and together with internal temperature and lighting sensors, controls the position of the louvres. Remote operation is also available via an internal modem interface.
  • Soltronic: A simplified version of ICS 4-Link, suitable for smaller projects.
