TW Photo voltaic (Tongwei) has unveiled new shingled photo voltaic panels for rooftop purposes.
“The Tongwei Terra shingled panel adopts Thermal Laser Separation (TLS) expertise the place the entire cell is reduce into a number of cell strips and interconnected utilizing conductive adhesive to attain a versatile connection,” stated the corporate’s spokesperson. pv journal. “It might optimize the construction of the photo voltaic panel and obtain zero cell spacing, which successfully will increase the light-receiving space of the panel.”
Shingle panels have a busbar-free construction the place solely a small portion of the cells are usually not uncovered to daylight. The cells are sure to kind a shingled high-density string and the ensuing strips are linked by a conductive adhesive. Lowering the variety of busbars reduces shadow losses.
The monofacial monocrystalline panel is on the market in six variations with energy outputs from 400 W to 430 W and an influence conversion effectivity between 20.1% and 21.7%. The open-circuit voltage is between 41.2 V and 41.8 V and the short-circuit present is between 12.41 A and 13.05 A.
The modules measure 1,812 mm x 1,096 mm x 30 mm and weigh 20.8 kg. It’s made with 3.2 mm tempered glass, an anodized aluminum body, and a junction field with an IP 68 ranking.
The brand new product can work with a system voltage of 1,500 V and temperatures starting from -40 C and 85 C. It reveals a temperature coefficient of -0.34% per diploma Celsius. The producer presents a 25-year product guarantee and a 25-year energy output guarantee for 84.80% of the preliminary yield.
“Tongwei Terra meets the wants of European clients in some ways and is widespread within the high-end European market,” stated the Chinese language PV producer. “The shingled panels are all designed from an architectural perspective. With the aesthetic traits of the structure, they completely meet the buildings which are waterproof, windproof, fireproof, windproof, and half that’s proof against snow and gives further eco-friendly qualities to buildings.
