Trina Vertex 390 W: In-Depth Review

Cell Technology

Trina has introduced ground-breaking technologies in recent years with its R&D team. The company has managed to produce effective solar panels with half-cell technology.  It is available at cost-effective prices when combined with its bifacial technology.

The company recently manufactured its 1/3 cut solar cell technology for its Vertex cells. This has helped increase the total light absorption along with higher output generation.

The multi-bar solar module technology has helped limit any ribbon resistance. It has also aided in reducing cell-based power loss. For the Trina Vertex 390W, the cell technology used is multi-busbar. This combined with a side wafer of 210mm, helps it produce 600W high output. It also has an efficiency that scales up by 21.4 percent.

The panels use bifacial technology with a double glass system. This helps maximize solar power generation by going as high as 30 percent. The 1/3 cut cells also help reduce major power loss with higher power generated for each watt.

Warranty/Guarantee

The Vertex 390 W solar panel comes with a 15-year warranty on the workmanship.

Efficiency

The Trina Vertex 390 W uses high-density square-mono cells and encapsulation technology.  This drives the panel to 21 percent efficiency. After ten years, the efficiency goes down to 92 percent, which is still an excellent number for a solar panel. After twenty-five years, this efficiency ranges from 84-85 percent mark.

 This brings the degeneration rate to 2 percent for the very first year. The range is 0.45 to 0.55 percent for the following years up until 25 years.

Peak Performance

With high panel efficiency, the 390 W panels would perform at their best for 10 years. Next comes a slow yet steady degeneration that isn't as much as other panels in the market. Under the right conditions, the panels provide a peach performance. This includes max power generation going as high as 600W.

Pros:

  • Outstanding aesthetics and visual appearance
  • Thinner wires that aren’t as noticeable
  • Small size with improved power generation properties
  • Easy mounting design
  • Improved resistance & current collection
  • 15-year manufacturer warranty

Cons:

  • POE encapsulant (Polyolefin elastomer-based encapsulant) required in humid & hot climates for added protection
