New 635-660 W Module Series from Trina

Chinese solar manufacturer Trina Solar launched a more powerful Vertex solar modules series at the SNEC PV Power Expo in Shanghai.

According to the product sheet for the series, the 132-cell solar panel is available in six versions offering power outputs of 635-660 W and with efficiency of a solar panel ranging from 20.4-21.2%. The solar panels measure 2,384×1,303x35mm and weigh 33.9kg.

Open circuit voltage is reported at 44.7-45.7 V and maximum solar power voltage ranges from 36.8-37.8 V, according to Trina. Short circuit current is reportedly 18.30-18.53 ampere with power tolerance 0%/+5%.

The operating ambient temperature ranges from -40 to 85 degrees Celsius, according to the product sheet, and maximum system voltage is 1,500 V. The reported temperature coefficient of Pmax is -0.34%/degree Celsius.

The solar module features a white backsheet, a 35 MW anodized aluminum frame and 3.2mm of tempered glass with an anti-reflection coating. Its junction box has an IP 68 rating.

Trina unveiled a 600 W version of the Vertex panel in mid-July. Building on the company’s 210mm-wafer-based; multi-busbar; high-density-interconnection; 500 W-plus products, Trina said the innovation that ramped up the output of that model still further was the use of half-cut rather than trisection-cut solar cells. The string power available for solar power projects could rise to 41% for developers who use the Vertex, the manufacturer said last month, with the product offering balance-of-system savings of RMB0.10/W ($0.014), thanks to a need for fewer cables, foundations, racking and other infrastructure. That would drive levelized cost of energy reductions of 2-3%, said Trina at the time.
