Kalzip® solar solutions The synthesis of design and function 2 Kalzip solar solutions

Freedom of creativity for environmentally conscious designers and architects Our partner for triple-junction technology: Environmental responsibility is a key driver in contemporary architecture. The creation of sustainable buildings is a practice which must benefi t future generations. Today the inclusion of on-site microgeneration technologies such as solar photovoltaic (PV) panels can make a signifi cant contribution to reducing carbon dioxide emissions to the environment. The introduction of PV systems onto the building envelope is no longer achievable through the installation of...

Kalzip solar solutions were developed in the interests of environmental protection and conservation of resources. Kalzip standing seam roof sheets are the ideal substrate for PV systems used for economical solar power generation on new buildings and renovated roofs, as well as when retrofi tting. A further alternative of power generation is the integration of PV systems into the façade as brise soleil. Under diffuse light conditions, the silicon thin-fi lm solar cells in the innovative triple-junction technology developed by our partner Uni-Solar, produce a greater energy yield than...

When referring to PV systems, a distinction should be made between in-plane and roof mounted systems. Corus Building Systems offers solutions for both options, which are optimised for the type of Kalzip roof being installed. For individual freedom of design, and simultaneous use of solar energy, Kalzip AluPlusSolar offers excellent benefi ts by means of a combination of extremely robust solar PV laminates and Kalzip profi led sheets, even making convex and concave constructions possible. Kalzip SolarClad is suitable for the design and installation of PV laminates on existing structures. The...

The new Kalzip AluPlusSolar solar panels are the fi rst to enable truly roof-integrated renewable power generation using fl exible PV laminates, while providing maximum freedom of creativity for challenging architecture. A wide variety of designs can be accommodated, as the solar laminate is permanently attached to aluminium Kalzip standing seam sheets. This integrated system allows individually designed roof elements with straight, convex, or concave shapes. Without the need for mounting frames, the solar cells are in-plane with the roof surface and convey a unique expressive character....

Kalzip® SolarClad: design fl exibility and low weight New possibilities for sustainable construction Kalzip SolarClad is a variation of AluPlusSolar optimised for overcladding metal roofi ng. Its fl exibility and versatility enable solar panels to be integrated into any Kalzip standing seam profi le. SolarClad provides a retro-fi t solution for installations on existing structures or for new new-build developments. PV laminates consist of extremely robust amorphous silicon thin-fi lm modules attached to aluminium carrier panels, which can be installed on any Kalzip standing seam system...

Kalzip® AluPlusSolar Roof-integrated, renewable power generation for aesthetic solar architecture The combination of thin-fi lm solar laminates with the benefi ts of the Kalzip standing seam roof sheet provides architects and designers of photovoltaic systems maximum freedom of design whilst making effi cient use of solar energy. PV laminates are factory-bonded to polyester or PVDF paint coated aluminium. Dimensions of Kalzip AluPlusSolar AF 65/537 mm Sheet thickness 1.0 mm Surface RAL 9006 Weight Approx. 7.0 kg/m2 (inc. solar modules) An overview of the product’s advantages • Aesthetic,...

Kalzip® SolarClad The retrofi t solution for all metal roofs – light and fl exible Kalzip SolarClad is suitable for all roof geometries with a pitch of up to 60°. Its low weight means only minor additional structural checks are required for the roof. Kalzip SolarClad is offered with PV laminates of two lengths, factory bonded to carrier trays ready for connection. Product advantages • Amorphous thin-fi lm laminates for lasting effi cient utilisation • Up to 20% higher energy yields than crystalline modules due to triple-junction technology • High shading tolerance due to tight bypass...

Strong partners: off-site construction using light steel framing combined with Kalzip® solar solutions Every year, large sums of money are spent on the repair and maintenance of poor quality fl at roofs, without providing a long-term solution. The Corus Hi-Point concept using lightweight steel construction, pre-fabricated off-site, is a system developed to ensure sustainable building protection. Providing numerous and signifi cant benefi ts in terms of safety, cost and design fl exibility, Hi-Point is ideally suited to fast track building projects. Complete roof modules can be quickly and...

Location and orientation The average annual solar irradiation in Europe ranges from 1,752 kWh/m² in southern Spain to 876 kWh/m² in the north of Scotland. Photovoltaic cells When PV laminates absorb light, they produce an electrical voltage, which results in the generation of a direct current. Solar cells are composed of layers of semiconductor materials which continuously convert light energy into electrical energy. This occurs by means of different silicon alloys which are specifi cally doped to absorb different regions of the visible spectrum. Solar electric systems Every grid-connected...
