Trina 405W Solar Panel 144 Cell PERC TSM-405-DE15M(II) Wholesale 30 panels per pallet

TSM-405-DE15M(II) is Trina Solar's TALLMAX M mono PERC monofacial module, built on 144 half-cut monocrystalline cells (6x24), with a white backsheet and standard aluminum frame. Its design pairs multi busbar technology with mono PERC cells for reliable performance suited to general rooftop and ground-mount installations.

Half-cut cell design brings higher efficiency, optimizing power output under inter-row shading conditions and reducing interconnection losses. The module is PID resistant, and every unit undergoes 2x 100% inline EL inspection, helping the panel maintain a strong output curve over its full service life.

Given its compact size and weight, the TSM-405-DE15M(II) efficiency of 20.2% is quite impressive. Reduced BOS costs come from higher power bins and 1,500V system voltage. Trina Solar backs this module with a 10-year product workmanship warranty and a 25-year linear performance warranty guaranteeing at least 83.1% output retention.

Higher efficiency of up to 20.2%

TSM-405-DE15M(II) guarantees outstanding power output. Multi busbar technology combined with mono PERC cells and high-transmission, AR-coated front glass results in 20.2% module efficiency, among the highest in its class at the time of release.

Better performance at high temperatures

Low thermal coefficients allow for higher energy yield at elevated operating temperatures. Every 1.8°F hike above 77°F will decrease your panel's efficiency by only -0.36%.

High quality standards

Every module undergoes over 30 in-house tests, including UV and thermal cycling, well beyond certification requirements, guaranteeing the reliability of the solar system. Certifications include IEC61215, IEC61730, UL1703, IEC61701 salt mist corrosion, IEC62716 ammonia corrosion, IEC60068 blowing sand, ISO9001, ISO14001, and OHSAS18001.

Low degradation for increased longevity

From the 2nd year to the 25th year, the average annual power decline will be no more than 0.6%. Guaranteed power starts at 97.5% and, after 25 years, the modules will retain more than 83.1% of their initial output.

Certified for standard wind and snow conditions

TSM-405-DE15M(II) is certified to withstand 5400 Pa of snow load and 2400 Pa of wind load. Such resistance is mainly due to the 35mm anodized aluminum alloy frame and 3.2mm AR-coated heat-strengthened front glass, with an IP68-rated junction box ensuring long-term weatherproof performance.
