1600 PowerWall® — More Information
Photovoltaic laminates replace spandrel panels, glass or other materials in vertical curtain wall or sloped glazing systems. Fully compatible with select customized Kawneer 1600 Wall Systems®, the PV laminates can be glazed conventionally or with two-sided structural silicone glazing (SSG), utilizing standard glazing procedures and equipment. Inverters convert the direct current (DC) energy generated by the PV laminates into usable alternating current (AC). PV laminates are available in a range of sizes to help balance energy, cost and aesthetic requirements.
The polycrystalline PV laminates consist of solar PV cells set between two layers of ethyl vinyl acetate (EVA) and are laminated between layers of glass. Overall thickness of a glass/ glass PV laminate ranges approximately 1/4 to 1/2 inch. PV laminates can also be incorporated in insulating glass units.
Thin film PV technology creates solar cells by depositing semiconductor materials in thin layers on glass. The thin film can be etched to provide various levels of transparency (typically to about 10%). Thin film laminates provide a uniform appearance and blend easily into almost any architectural design.
The amount of peak generating capacity installed can vary from 4 up to more than 10 Watts DC per square foot, depending on the system design and the PV technology used. The polycrystalline and thin film PV laminates used in 1600 PowerWall® are typically guaranteed by their manufacturer to provide at least 90 percent of rated power for 10 years and 80% for 20 years. 1600 Wall Systems® have demonstrated compliance with the following performance standards:
Air Infiltration ASTM E-283
Static Water Penetration ASTM E-331
Dynamic Water Penetration AAMA 501.1
Structural Performance ASTM E-330
Seismic Performance AAMA 501
1600 PowerWall® enables building owners and architects to make their buildings stand out while reducing both energy purchase requirements and carbon and overall environmental footprints. Significant incentives are also often available to help reduce the net initial cost of a building integrated PV system.
The output of 1600 PowerWall® depends upon several project-specific characteristics including laminate design, PV technology used, project location and available solar resource, laminate tilt and orientation, and shading. 1600 PowerWall® reduces the amount of electricity that a building might otherwise need to purchase from its utility at retail prices. Solar PV systems generally provide the most electricity when energy demand and energy prices are highest, and they do so without any emissions.
For the Finishing Touch
Permanodic® Anodized finishes are available in Class I and Class II in seven different colors.
Painted Finishes, including fluoropolymer that meet or exceed AAMA 2605, are offered in many standard choices and an unlimited number of specially-designed colors.
Solvent-free powder coatings add the “green” element with high performance, durability and scratch resistance that meet the standards of AAMA 2604.
