Solar PV - Solar PV Glass - Thin Film Solar
Solar PV Glass provides architects with components that can be integrated into buildings, making it possible to create renewable electricity while producing a variety of exciting design solutions
Solar PV Glass
Solar PV Panels can be used to replace a number of architectural elements that are commonly manufactured from glass. Using Solar PV Cells in building facades and rooflight systems can result in an economical use of solar energy and creative architectural design.
Solar PV Glass Design
Solar PV Glass design consists of Solar PV Cells that are built into transparent double and triple glazing units. Solar PV Glass can easily be integrated into roofs and building facade systems. It is generally available as a comprehensive package, complete with all the necessary electrical components and equipment.
Transparent Solar PV Glass
Transparent Solar PV is so called to differentiate it from the commonly available crystalline Solar PV Panels which are opaque. The word transparent refers to the background material e.g. glass and not the Solar PV Cells themselves, which are opaque.
Semi-Transparent Solar PV Glass
Solar PV Glass is assembled by placing Solar PV Cells on a panel of glass. By adjusting the distance between Solar PV Cells, it is possible to regulate the light transmission and consequently the level of shading provided inside the building. When Solar PV Cells are positioned widely apart, the panels become more transparent. When the cells are positioned closely together, they are semi-transparent and produce a dappled effect, or as one architect described them 'like sunlight filtered through trees'.
Solar PV Thin Film on Glass
Solar PV Thin Film cells can be printed on glass in several thin layers in order to produce the desired modules. Manufacturing them requires less material than is required for crystalline cells because no cutting is needed. In addition, they only require laminating on one side as they are already bonded to a glass panel during the manufacturing process.
Solar PV Glass - Insulating
Solar PV Glass is available in a variety of combinations of glass types, thicknesses and strengths. Double and triple glazing assemblies provide improved thermal insulating performance. Additionally, the use of laminated safety glass offers architects and builders a choice of design possibilities while improving safety and technical performance.
Solar PV Glass Bonding
Laminated glass used in architectural products incorporates a protective resin bonding layer, typically Polyvinyl Butyral (PVB), positioned between two panels of glass. The bonding process takes place under heat and pressure. When laminated under these conditions, the Polyvinyl Butyral interlayer becomes optically clear. When sealed together the glass sandwich behaves as a single unit and looks like ordinary glass.
Solar PV Glass Sheets
The photovoltaic circuit is formed on a sheet of glass using thin film deposition and patterning techniques. Polyvinyl Butyral and a second sheet of glass are then placed directly on the circuit.
The lamination of this sandwich encapsulates the circuit, protecting it from the external environment. Electric current is extracted from the module at a sealed terminal box that is attached to the circuit and then converted to alternating current (AC) by an inverter.
Solar PV glazing is generally available in large panels, typically up to sizes of 2.4 metres in length by 5.1 metres in height
