These modules feature a **half-cut** architecture and **Multi-Busbar (MBB)** technology, enhancing current collection and enabling stable performance even under partial shading and challenging operating conditions. The manufacturer also highlights **enhanced resistance to hotspots and high temperatures**, contributing to more predictable performance during the summer season and reducing the risk of performance degradation over time. A key advantage of this series is the high power output per module, which minimizes the number of panels required in a project-thereby reducing installation time, decreasing the number of DC connections, and optimizing the structure and logistics. The TSM-DE19R is particularly suitable for **C&I and utility-scale PV projects**, where lower BOS costs, more efficient maintenance, and maximum energy yield from available space are top priorities. ## Notable figures - At 20.9% efficiency, this panel is on par with typical \*\*PERC 550-600W\*\* modules - At 209.2 W/m², this panel generates 3.7 W/m² less per unit area than \*\*PERC 550-600W\*\* median (212.9 W/m²) - Temperature coefficient of -0.34%/°C matches the \*\*PERC 550-600W\*\* median - At 28.1 kg, this panel is 2.7 kg lighter than \*\*PERC 550-600W\*\* median (30.8 kg) - easier handling during installation - In the top 72% for efficiency among all PERC panels ## Questions ### Is the Trina Solar Vertex TSM-DE19R series still available for purchase? The TSM-DE19R series has been discontinued from Trina Solar's current production lineup and replaced by newer models using TOPCon cells. Modules from this series may still be available through distributor stock or clearance offers, but buyers should verify current inventory and warranty coverage, as service support for discontinued series can be more limited. ### What warranty comes with the Trina Solar Vertex TSM-DE19R panels? Trina Solar backs the TSM-DE19R modules with a 12-year product warranty and a 25-year linear power warranty, guaranteeing at least 84.8% of nominal output after 25 years. This is a standard protection level for Tier 1 panels, though buyers purchasing a discontinued series should confirm with the seller that manufacturer warranty coverage is still fully honored. ### Are the Vertex TSM-DE19R panels bifacial? No, the TSM-DE19R series consists of monofacial modules built with half-cut PERC cells. Unlike bifacial panels, they generate power only from the front side, which is sufficient for standard rooftop or ground-mount installations without rear-side light reflection. If additional rear-side yield matters, consider Trina's bifacial series, such as Vertex N. ### How many TSM-DE19R panels are needed for a 10 kWp system? With a unit power of up to 585 Wp, roughly 17 modules are needed for a 10 kWp system, depending on the chosen power bin within the 565-585W range. The high per-panel output reduces the module count compared to older series, shortening installation time, cutting the number of DC connections, and lowering mounting structure costs. ### Are Vertex TSM-DE19R panels suitable for a residential sloped roof? At 2382x1134 mm and 28.1 kg, TSM-DE19R modules are fairly large and heavy, making them best suited for commercial (C&I) installations and PV farms where maximizing yield per available surface is the priority. Installation on a residential sloped roof is possible but requires an adequately reinforced structure and careful handling of the larger module size during rooftop transport. ### How does the TSM-DE19R series perform in high summer temperatures? Trina Solar states enhanced hot-spot resistance and a power temperature coefficient of -0.34%/°C, a strong figure for PERC technology. This means the module loses relatively less power under intense heat on sunny summer days compared to older designs, resulting in more predictable energy yield during the season. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/dt-m-0033-f-datasheet-vertex-de19r-en-2024-b-6417eba15dc9.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, +3.9 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, +3.7 pp, +5 yr warranty | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, lighter, +3.5 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | Cooler, +3.5 pp, +5 yr warranty | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | Cooler, +3.5 pp, +5 yr warranty | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | Cooler, +3.4 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | Cooler, +3.3 pp, +5 yr warranty | | [Trina Solar TEB-NEGA6ND.48-420 (Silver Grey, RAL9018)](https://comparepv.com/panel/trinasolar-evergreen-shanghai-pv-tech-co-ltd-teb-nega6nd-48-420-silver-grey-ral9018) | 420 W | -145 W, cooler, -5.4 pp | | [Trina Solar TEB-NEGA6ND.48-425 (Silver Grey, RAL9018)](https://comparepv.com/panel/trinasolar-evergreen-shanghai-pv-tech-co-ltd-teb-nega6nd-48-425-silver-grey-ral9018) | 425 W | -140 W, cooler, -5.2 pp | | [Trina Solar TEB-NEGA6ND.48-430 (Silver Grey, RAL9018)](https://comparepv.com/panel/trinasolar-evergreen-shanghai-pv-tech-co-ltd-teb-nega6nd-48-430-silver-grey-ral9018) | 430 W | -135 W, cooler, -5.0 pp | | [Trina Solar TEB-NEGA6ND.48-545 (Green, RAL6001)](https://comparepv.com/panel/trinasolar-evergreen-shanghai-pv-tech-co-ltd-teb-nega6nd-48-545-green-ral6001) | 545 W | Cooler, heavier, -0.7 pp | | [Trina Solar TEB-NEGA6ND.48-550 (Green, RAL6001)](https://comparepv.com/panel/trinasolar-evergreen-shanghai-pv-tech-co-ltd-teb-nega6nd-48-550-green-ral6001) | 550 W | Cooler, heavier, -0.6 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +115 W, cooler, +4.3 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +110 W, cooler, +4.1 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +135 W, cooler, +4.1 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +130 W, cooler, +4.0 pp | --- Source: https://comparepv.com/panel/trina-solar-co-ltd-tsm-de19r-565 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
