Trina Honey 290W transparent bifacial solar panel
The Trina Honey 290W TSM-290NEG9M4C.26 is an N-type i-TOPCon bifacial dual-glass monocrystalline solar panel. Its transparent rear glass and compact format make it suitable for projects where light can reach both sides of the module, including solar carports, canopies, pergolas, façades and specialist mounting structures.
The module can generate from the rear as well as the front when reflected light reaches the rear glass. Actual bifacial gain depends on mounting height, roof or ground reflectivity, spacing, shading and array layout, so this should be assessed for every project.
Key features
- 290 W rated output: A compact module option for specialist solar applications and projects with restricted installation space.
- N-type i-TOPCon bifacial cells: 56 monocrystalline cells with 80 ± 7% stated power bifaciality.
- Transparent dual-glass construction: 2 mm heat-strengthened glass on both sides, allowing rear-side light access in suitable installations.
- Robust loading specification: Rated for 5,400 Pa positive load and 2,400 Pa negative load.
- Long-term performance cover: Five-year product workmanship warranty and 15-year power warranty, with stated 2% first-year degradation and 0.85% annual power attenuation.
Where to use
The Trina Honey 290W transparent bifacial solar panel is suitable for solar carports, canopies, pergolas, balconies, façades, agricultural structures, lightweight roofs and specialist commercial solar installations. It is particularly useful where a bifacial module is needed in a compact 1,650 × 992 mm size.
For best use of the bifacial design, install the panel where the rear surface can receive reflected light. The final mounting arrangement must allow for the module size, 21.0 kg weight, glass-glass construction, drainage, approved clamping zones and site-specific structural loads.
Energian can help with mounting selection, inverter compatibility, bifacial layout design, cable selection and complete system planning. Where the installation is not suitable for self-installation, we can support delivery through trusted installation partners.
