Eurener 400W Terracotta TOPCon N-Type Double Glass Bifacial Solar Panel
- 400W N-type TOPCon solar panel with a terracotta-coloured finish for roofs and façades where visual integration matters.
- Double-glass bifacial construction, designed to generate from both the front and reflected light at the rear where installation conditions allow.
- Compact 2.00m² module format with an IP68 junction box and 1,500V maximum system voltage.
Eurener 400W Terracotta Bifacial Solar Panel
The Eurener MEPV Terracotta Double Glass Bifacial 400W is a coloured N-type TOPCon solar panel for projects where a standard black or silver-framed module would not suit the building. Its terracotta anodised aluminium frame and coloured front finish make it a practical option for tiled roofs, heritage-sensitive properties and architectural solar installations.
The module uses bifacial monocrystalline N-type cells within a double-glass structure. Where the rear of the panel receives reflected light, such as on elevated roof systems, canopies or suitable ground-mounted arrays, it may contribute additional generation. Actual rear-side yield depends on mounting height, spacing, shading and surface reflectivity.
Key features
- 400Wp front-side rated output with module efficiency of up to 20.02%.
- Terracotta anodised aluminium frame for a more sympathetic match with terracotta roof finishes.
- N-type bifacial monocrystalline cell technology with a quoted bifaciality factor of 80 ± 5%.
- 2mm anti-reflective tempered front glass and 2mm tempered rear solar glass.
- IP68 junction box, three bypass diodes and original MC4-Evo 2 connectors.
Where to use
Use this Eurener 400W Terracotta solar panel on tiled domestic roofs, commercial buildings, agricultural buildings, canopies and building-integrated solar projects where colour coordination is important. It is particularly suitable where planning, conservation context or architectural design calls for a less visually prominent alternative to conventional solar panels.
For bifacial performance, avoid mounting methods that fully cover or heavily shade the rear glass. A suitable mounting system, string design and inverter configuration are required. If you need help selecting compatible rails, roof hooks, clamps, optimisers or an inverter, contact Energian’s UK expert support team. We can also introduce trusted installation partners for projects that require professional design and installation.
