Trina Solar uses split-cell technology in their production, where they replace all their full cells with half-cut solar cells. The two half-cell pieces are then arranged in a series formation. This helps reduce the power loss due to ribbon resistance to just a ¼ of that in full cells and improves their efficiency by 2%.
This technology also comes with a string cell design that ensures every cell string works independently. The cell design is excellent at reducing the impacts of module shading and overall power loss.
Additionally, the monocrystalline technology used gives your roof a uniform and aesthetically pleasing look.
Trina Solar’s emphasis on cell efficiency ensures that its panels’ output is at least 90% of its initial output after the first 10 years and around 80% after 25 years. After the first year, its degradation rate stands at 0.5% annually.
The solar panels come with an extended 25-year linear power warranty and a 12-year product workmanship warranty.
The TallMax 345-385W – TSM-DE14H(II), however, still has a 10-year product workmanship warranty.
Depending on the panel you choose, the TallMax 9BB, 390-415W – DE15M(II) solar panel can achieve a 415W output with a 20.4% module efficiency. The TallMax 5BB, 385-410W – TSM-DE15H(II) can achieve up to 410W with a 20.2% efficiency, and the TallMax 345-385W – TSM-DE14H(II) can attain a 385W output with a 19.9% efficiency.
Panels needed for 6.6kW solar system

The Vertex Prime solar panels adopt Trina’s game-changing multi-busbar technology alongside the 210mm side wafer, non-destructive cutting, and the high-density interconnected tech to achieve a high 600W output and up to a 21.4% efficiency. This new cell string setup also helps in reducing the BOS (Balance of the system) costs.
The panels also use the double glass ‘bifacial’ technology that maximizes power generation by almost 30%.
The use of 1/3-cut solar cells instead of the half-cut solar has also proven to be critical in reducing power losses and increasing the power generated per watt.
After 10 years, the panels generate around 92% of their initial power output, and after 25 years, the efficiency goes slightly lower to 84 – 85%. The panels have a slow degeneration rate which is great as it ensures your solar panels last longer and pays back faster.
Contrary to Trina’s standard 10-year workmanship warranty, most Vertex solar panels come with a 12-year warranty and 25 – 30 years power warranty.
The Vertex 550W TSM-DE19 MBB / 535 – 555W has a max output of 555W on a 110-cell module, with a 21.2% module efficiency.
Their Vertex 550W TSM-DEG19C.20 MBB / 530 – 550W has a max output of 550W on a 110-cell module with a 21.0% efficiency. The Vertex 600W TSM-DEG20C.20 MBB / 580 – 600W generates a max of 600W under optimum conditions, with a 120-cell module and a 21.2% module efficiency.
The Vertex TSM-DE18M(II) 1/3-cut, MBB, 480-505W, has a max output of 505W on a 150-cell solar panel and 21.0% module efficiency.
Panels needed for 10kW solar system
For a 10kW solar system, you’ll only need 16 Vertex solar modules to get the most of your system. But due to the high output of each solar module, these panels are suitable for solar farms and large-land solar installations.
