Trina Solar's Colored Dual Glass Module series was designed with building roof and facade integration in mind - where standard black panels mar the architectural design. Its greatest advantage is the ability to choose the color, thanks to the use of colored glass, allowing the PV installation to match the building's style, rather than the other way around. This solution is particularly valued by investors who must balance aesthetic, conservation, or design requirements with actual energy production.

The dual-glass construction increases resistance to material aging and harsh environmental conditions, and also supports fire safety in BIPV applications. In practice, this means more stable performance and a lower risk of operational issues on roofs and facades exposed to wind, humidity, and temperature fluctuations. The modules are based on N-type TOPCon technology, highly regarded for its low degradation and good performance at high temperatures, translating to a more predictable yield over time.

This is the choice for architects, developers, and companies implementing BIPV - from premium rooftops to commercial facades, where both appearance and energy matter.

Common questions

6 answered
Does the colored glass in Trina Solar Colored Dual Glass Module panels reduce their power output?
Colored glass causes a slight drop in light transmission compared to standard black panels, but N-type TOPCon cells keep this loss to a minimum. The modules still reach a maximum power output of up to 560 Wp, so investors get a color-matched facade or roof without giving up real energy yield - which is the whole point of this series.
What warranty applies to Trina Solar Colored Dual Glass Module panels?
As a Tier 1 manufacturer, Trina Solar provides a 10-year product warranty and a 25-year linear power output warranty. This is standard for modern N-type TOPCon modules and gives investors confidence in stable performance over a quarter century.
Are Colored Dual Glass series panels suitable for building facades (BIPV)?
Yes, that's one of the series' primary applications. The dual-glass construction improves resistance to weathering and supports fire safety required in BIPV installations, while the choice of glass color lets you integrate the panels into a facade without the contrasting black surfaces typical of standard modules.
How does the dual-glass construction differ from a standard panel with a backsheet?
In a dual-glass module, cells are laminated between two glass panes instead of glass and a polymer backsheet. This increases rigidity, protects against moisture and micro-cracks, and extends service life on roofs and facades exposed to wind and temperature swings, at the cost of slightly higher panel weight.
Does TOPCon technology in these panels handle heat better than older PERC cells?
Yes, N-type TOPCon cells have a lower temperature coefficient and slower degradation over time than older P-type PERC cells, so on hot days they lose less power and maintain a more predictable energy yield throughout the system's operating life.
Are Colored Dual Glass modules bifacial?
No, this series uses a monofacial design - the colored glass on the back limits light transmission from the rear side, so the panel generates energy only from its front surface. This is a deliberate trade-off: giving up bifacial gain in favor of the aesthetics required in BIPV and facade projects.
