Bürkle has developed a new three-step single-opening laminator focusing on a number of key process parameters to reduce costs and increase productivity. The e.a.sy-Lam SL machine is claimed to reduce unit costs per solar module by up to 25%. 

Problem

Uptime and overall reliability in the lamination process has been a critical factor in high-volume applications. Overall cost reduction requirements are pushing for higher throughput. The need to address both aspects is now a priority for a competitive, high quality finished product. Increasing operating temperature reliably could reduce process times.

Solution

The e.a.sy-Lam SL laminator has been designed to reliably enable the temperature for laminating glass-foil modules to be increased to improve the cross-linking speed. Depending on the foil type, an increase of the operating temperature by 10ºC to for example 160 degrees can double the cross-linking speed. Combined with a higher pressure and a reduction of the evacuating time, it is possible to reduce the process time to a claimed 3 ½ minutes. The use of one three-step e.a.s.y-Lam SL system could replace up to four single-opening laminators, according to the company.

Applications

Laminating glass-foil modules.

Platform

The laminator ensures the same overall temperature is achieved of the thermal oil so that the module quality is not affected by local temperature deviations in the heating platen by being separated. Conventional heating elements are integrated into the heating platen so that a failure can damage the modules in the affected area. It is anticipated that most existing systems can be upgraded to the new SL technology at extra cost.

Availability

September 2011 onwards.

The rooftop solar PV market is set for significant growth, but installers are being held back by complicated design software that is slow, cumbersome and fails to take into account rooftop shading, module compatibility and energy storage. Huawei’s SmartDesign 2.0 is a web-based PV and energy storage system tool that promises to solve all of those issues, and much more. This webinar will provide a live demonstration of the SmartDeisgn 2.0 tool, showing how installers can quickly complete Huawei PV & ESS system designs and assemble a professional report with 3D site view for potential customers, streamlining the design and sales service.
