Support for the Chinese Megaproject: Solar Glass Production with Grenzebach Pattern Glass Lines

19.07.2021 - Environmental protection: With support of Grenzebach, pattern glass production facilities, specially to manufacture solar panels, are being built in China.

“We listened to the market and learned from the experience. So we optimized and right-sized our pattern glass production facilities 100 percent in accordance with our customers’ needs.”

This involves a brand-new design of the pattern glass production line. The complete plant is designed for performance, cost-efficiency, and the specific demands of the Chinese solar glass market.

All these demands are not easy to reconcile. The manufacturing process requires a great deal of know-how and equipment that is guaranteed to work reliably. For example: In order to supply high-quality base glass for the solar module, the edges have to be precisely cut to a specific format and the sheets then stacked neatly. At Grenzebach, customers can rely on everything working smoothly. The company supplies both hot and cold end technology – in other words, the complete production line with all components from the annealing lehr to cold end with conveyor, cutting and stacking technology. High efficiency and flexibility are ensured by reliable equipment, such as robots with high stacking accuracy. Downstream of the cutting line, Grenzebach also supplies conveyor and automation technology to transport the raw glass for further processing. In this step, for example, edges are ground and prepared for later use in the solar module. At this point, cutting precision pays off again by increasing grinding efficiency and cycle time and reducing the cost of expensive grinding material.

James Shang underlines the company’s good standing in the Chinese market: “We have a really good relationship with all our Chinese customers; we know the demands of the market and are happy to support our customers with our new pattern glass lines now.”

A wide Range of Pattern Glass Variants can be delivered

With Grenzebach’s pattern glass lines, glass thicknesses from 1.5 to 6 mm are possible. Manufactured glass plates range from 1,200 mm x 2,400 mm to 2,650 mm x 2,800 mm – matches perfect for Chinese solar panels. The capacity of one line varies typically from 125 to 300 tons per day.

The customer demand is definitely impressive: A large number of lines have already been ordered and will be delivered in the course of the year. The first customer has purchased twenty lines at once, which will be installed in spring 2021. As standard, the schedule of customer projects from idea to completion is around eight months. Standardization and series production have enabled Grenzebach to shorten delivery times and support customers with even better in their ambitious projects. But that is far from the end: Grenzebach also takes care of maintenance and service, and this over the entire lifecycle of the line. The experts at Grenzebach's manufacturing site in Jiashan close to Shanghai support Chinese plant operators in making optimum use of the pattern glass lines and furthermore, can also supply spare parts at short term.

A big Win for the Environment

With its solar glass lines for China, Grenzebach is not only making a major contribution to the use of "green" energy in East Asia, but is also helping to avoid additional energy demand elsewhere: Local production means fewer overseas and overland transports are required - and that in turn means a further, significant reduction in climate-damaging emissions. This makes these plants an investment in the future in the best sense of the word.
