The use of **dual-glass technology** provides them with exceptional mechanical rigidity and longevity, effectively eliminating the risk of micro-cracks or degradation caused by chemical factors. Crucially, these modules utilize an **innovative color coating**, which allows for precise matching of the installation to the color of the facade or roofing without significantly limiting light absorption. They solve the problem of restrictive conservation requirements and the high expectations of architects, for whom traditional panels are often too contrasting. Thanks to the use of advanced **n-type i-TOPCon cells**, the TEG series guarantees excellent efficiency and a low temperature coefficient, which clearly distinguishes it from less effective BIPV solutions. These modules are dedicated to premium segment investors and public utility buildings, where maintaining **high architectural aesthetics** while ensuring maximum system durability is key. This solution eliminates the compromise between the building's appearance and its energy independence, focusing on modern design and the highest fire safety standards. ## Notable figures - Efficiency of 20.3% is 2.1pp below the \*\*TOPCon 550-600W\*\* median (22.4%) - At 203.4 W/m², this panel generates 21.0 W/m² less per unit area than \*\*TOPCon 550-600W\*\* median (224.4 W/m²) - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 550-600W\*\* panels - At 33.0 kg, this panel is 1.8 kg heavier than the \*\*TOPCon 550-600W\*\* median (31.2 kg) - more demanding for installation crews - In the top 84% for efficiency among all TOPCon panels ## Questions ### Do colored Trina Solar TEG Colored Dual Glass Modules lose a lot of power compared to standard black panels? Conventional colored PV coatings can reduce cell efficiency by as much as 15-30%, but the TEG series uses an advanced color coating engineered to minimize light absorption losses. Combined with high-efficiency n-type i-TOPCon cells, the modules still reach up to 560 Wp, allowing facade aesthetics to be preserved without a drastic sacrifice in energy yield. ### What warranty comes with the Trina Solar TEG Colored Dual Glass Module? Trina backs the TEG series with a 10-year product warranty covering material and workmanship defects, plus a 25-year linear power output warranty. The dual-glass construction further boosts mechanical durability, meaningfully lowering the risk of performance degradation over the module's lifetime-particularly relevant for premium projects and public buildings. ### How does the TEG Colored Dual Glass Module differ from a standard PV module? The key difference is the innovative color coating, which lets the panel be color-matched to a facade or roof covering-something standard black modules can't offer. In addition, the dual-glass build replaces the typical backsheet, increasing rigidity and resistance to micro-cracks and chemically induced degradation, making TEG a dedicated solution for premium architecture and heritage-restricted sites. ### Is the TEG Colored Dual Glass Module bifacial? No, the TEG Colored Dual Glass Module series is monofacial despite using dual-glass construction. Here, the dual-glass build is primarily used to improve mechanical durability and integrate the color coating, rather than to generate energy from the rear side of the panel as bifacial modules do. ### What cell technology does the TEG series use, and how does it compare to typical BIPV solutions? The TEG series uses advanced n-type i-TOPCon cells, which deliver higher efficiency and a lower temperature coefficient than the standard PERC cells found in many BIPV products. This means the modules handle high operating temperatures on facades and roofs better, maintaining stable energy output even in summer conditions where typical BIPV panels lose more power. ### What kind of buildings are Trina Solar TEG Colored Dual Glass Modules best suited for? TEG modules are designed primarily for premium-segment projects and public buildings where visual consistency with the surroundings matters, such as heritage facades or conservation-protected zones. They work well anywhere standard black panels would clash with the architecture, while still giving investors the durability and fire safety standards expected from a modern PV installation. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/datasheet-teg-colored-dual-glass-module-1-a42401aa079e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Lighter, +4.7 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Lighter, +4.5 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Lighter, +4.4 pp, +5 yr warranty | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | Lighter, +4.4 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Lighter, +4.3 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | -50 W, lighter, +4.2 pp | | [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 | -130 W, -4.8 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 | -125 W, -4.6 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 | -120 W, -4.4 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 | Very close match | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +130 W, +4.9 pp, +5 yr warranty | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +125 W, +4.7 pp, +5 yr warranty | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +150 W, +4.7 pp, +5 yr warranty | | [WINAICO WST-675BKX72-A2](https://comparepv.com/panel/winaico-wst-675bkx72-a2) | 675 W | +125 W, +4.7 pp, +5 yr warranty | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +145 W, +4.6 pp, +5 yr warranty | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +120 W, +4.5 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/trina-solar-teb-nega6nd-48-green-550w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
