The Trina TSM-290NEG9M4C.26 Dual Glass Transparent Bi-facial Silver frame is a compact and versatile bifacial solar panel for renovation, replacement and complex rooftop projects. Thanks to its 290W output and 17.7% efficiency, this module is especially suitable as a modern replacement for legacy 60-cell panels. Its transparent dual-glass construction, low weight and compact format make installation easier in space-limited layouts, multi-angle roofs and partially shaded areas.

  • 290W output: a practical replacement module for older 60-cell panels.
  • 17.7% module efficiency: solid yield in a compact 1650 × 992 mm format.
  • Transparent bifacial dual-glass: around 20% light transmittance and potential 10–20% rear-side gain.
  • N-type i-TOPCon technology: improved temperature behaviour, low degradation and dependable energy yield.
  • Ideal for off-grid cabins and boats: its specifically compact format combined with N-Type quality makes this module a strong choice for smaller autonomous energy systems.

Why choose the Trina TSM-290NEG9M4C.26?

This module is designed for projects where compact dimensions, easy replacement and reliable performance are essential. It features a maximum system voltage of 1500V DC, a maximum series fuse rating of 20A, a 2.0 + 2.0 mm glass structure and a mechanical load rating of 5400 Pa positive and 2400 Pa negative. The module uses N-type i-TOPCon monocrystalline cells, a silver anodized aluminium frame and an IP68 junction box. This makes it a strong option for installations where space saving, replacement compatibility and long-term durability matter.

Please note: this panel weighs 21.0 kg and must be installed by qualified professionals. Mounting hardware, grounding components and other installation accessories are not included. Trina states in the manual that grounding materials must be supplied by third parties. Use only suitable UV-resistant PV cable of at least 4 mm² (12 AWG), keep at least 100 mm clearance from the roof or wall, and do not mate connectors from different brands or connector types.

What is this module especially suitable for?

This model is particularly suitable as a replacement module for older 60-cell panels and for roofs with limited space, multiple roof angles or partial shading. Thanks to its compact 1650 × 992 mm footprint and 21.0 kg weight, it is easier to handle than larger utility-style modules. It can also be an attractive option for off-grid cabins and boats when the system is electrically designed correctly.

What installation requirements are important?

Trina requires installation by qualified professionals. Use UV-resistant copper cable of at least 4 mm², ensure correct grounding, keep at least 100 mm rear clearance for ventilation, and only use compatible mating connectors. During installation, the module should preferably be covered to reduce unintended DC generation.
