This week during Intersolar Europe, Sunways has been demonstrating its latest technology advancements including its Eco-Line solar modules, roof solutions and new storage technology for private consumption. The company began by presenting its high-efficiency solar cells with P3 technology, which Sunways states holds an 18% efficiency rating.
The solar cells are said to achieve a high yield rate using an exact wafer specification, which is combined with Sunways’ processes for solar cell production, leading to the prevention of the LID effect: a light induced degeneration of monocrystalline solar modules. Sunways also notes that its P3 technology can suppress the voltage-induced performance degeneration of mono- and multicrystalline solar cells. Along with completing several validation tests, the solar modules come with a 10-year product warranty.
Sunways has also revealed its in-roof mounting system, which includes an in-roof laminate, using solar modules that sport 48 monocrystalline solar cells in a black design. The in-roof laminates are available in output classes of 187.5W, 190W, 195W and 200W. The company has additionally enhanced its product portfolio with a 60-cell solar module for output classes from 260Wp. Declared to have more than 16% module efficiency, the high-performance solar module will be available starting in 2011’s fourth quarter.
The company debuted its new product concept for a storage solution, which allows for private consumption of PV electricity above the usual 20% to 40%. Based on the 4.7kWh Li-Ion storage modules, which features an integrated battery management system for insertion into an existing PV system, the storage unit’s charging can be changed to fit individual energy-consuming appliances such as hot water tanks, washing machines or refrigerators. Sunways anticipates launching the storage solution into the market sometime in 2012.
Sunways is exhibiting at Intersolar Europe, booth A4.180.
