Sunpreme Demonstrates the World's First 500W Bifacial Double Glass Module

Publicado el 22 oct. 2014
Sunpreme announced that it has demonstrated the world's first Bifacial double glass module with a measured STC output of 503W. With a 15% bifacial power boost, the effective panel wattage can be enhanced to 575W with an effective module efficiency of 22.2%. A second performance bonus comes from a record low thermal coefficient of module efficiency of 0.28%/C. The product is designed to achieve an unsurpassed BOS (Balance of System) cost reduction for distributed power generation applications. 

Sunpreme's new 500W panel uses the same design and materials technology as its current line of Maxima GxB series. The underlying technology platform is Sunpreme's proprietary SmartSilicon® Hybrid Cell Technology (HCT) developed 5 years ago. The proven construction consists of 156.75mm AFS cells sealed between two panels of tempered glass. With a frameless design, there is no need for grounding. Such innovative double glass modules have proven easy to install and maintain even when deployed at multi-MW volumes. 

"I am delighted to see the rapid progress Sunpreme has made with its Bi-facial Hybrid Cell Technology packaged into double glass frameless panels. Both the Sunpreme HCT cell and its module are key elements of a high-tech product portfolio, that until recently included half a dozen different mainstream technologies spanning a module efficiency range from 14% to 21%," said Dr. Eicke Weber, Director of Fraunhofer ISE and a member of Sunpreme's Global Advisory Board. "With its record module efficiency of about 22% with bi-facial boost, Sunpreme HCT technology has moved right to the top of the class. And, it is able to do so in a cost effective manner even at a small scale volume. Going forward, Sunpreme clearly has room for an enormous upside in further cost reduction," added Dr Weber.

"We are proud to claim the Sunpreme GxB 500W(STC) as the world's new 'Heavy Watt' champion. An effective power of 575W, post Bifacial boost, equivalent to a 22.2% panel efficiency brings out unsurpassed BOS cost benefits for large Distributed Power Generation projects. At 34 kg, we are close to the weight two installers can do repetitive lifts," said Dr Ashok K Sinha, Chairman and CEO of Sunpreme. "With such a 'one-of-a-kind' product we are setting a new industry bench mark. Our innovative design exceeds the limits of STC and PVSyst standard. We help our customers achieve a lower LCOE with a higher energy yield. These add up over the 25 year life of these panels. Upon full market release, the product warranty will, like our other products, be backed by Munich Re. In the end, our intent is to provide our customers and investors an outstanding Internal Rate of Return (IRR)," added Dr Sinha.

Frank Pham, Sunpreme's Sr VP for Global Engineering and Operations said: "Rapidly demonstrating leading edge products such as the GxB500W was enabled by executing to our corporate values of continuous innovation and lean operations. By building on a tested and proven HCT platform with Bifacial double glass modules, we were able to demonstrate an STC flash power of 503W. These panels share the gene pool of the GxB product family, e.g. high Voc for efficient systems integration, the highest fire class A rating, a higher snow load and wind resistance." Because of its intended application and unique nature of the product, "We expect to work closely with selected customers on applications engineering matters, including compatible racking and tracker configuration," added Frank.
