Solar panel TONGWEI - TWMNH-48HW - 465 Wp - NType Topcon

Tongwei TWMNH-48HW 465 Module Wp — N-Type TOPCon Dual Glass, Black Frame

Tier 1 module, TNC N-Type cell, Dual glass and anodized black frame: the Tongwei TWMNH-48HW delivers 465 Wp with a thermal coefficient among the best in its category.

TNC N-Type TOPCon technology: what changes for the installer

The TWMNH-48HW series is based on the TNC (Tunnel Oxide Passivated Contact) cell in N-Type technology, half-cell configuration 96 cells [6×16] , produced in Tongwei Solar (TW Solar) factories, a Bloomberg NEF Tier 1 manufacturer with world number 1 in PV cell production capacity.

Key performance indicators at STC:

• Power : 465 Wp — tolerance 0/+3%

• Module yield : 23.3%

• Maximum thermal coefficient Pmax : -0.28%/°C — actual gain in warm roof vs. standard P-type (-0.35 to -0.40%)

• Voc : 36.40 V | Isc : 15.92 A | Vmp : 30.56 V | Imp : 15.22 A

• Maximum system voltage : 1500 V DC — compatible with C&I parks and large multi-string residential installations

• Junction box : IP68, 3 diodes — full protection against moisture and partial shade

Dual Glass Construction, Black Frame: Durability and Aesthetics

The Dual glass construction — 2.0 mm AR semi-tempered front glass + 2.0 mm semi-tempered rear glass — combined with the black anodized aluminum frame positions this module on high-end projects and visible urban rooftops.

Differentiating constructive points:

• Certified hail resistance according to IEC 60068-2-68 — a strong specification argument for exposed markets (East, Alps)

• Static load : 6000 Pa front face / 4000 Pa rear face — tile, slate, zinc roofs

• 4 mm² cable (+/-1200 mm) — installation flexibility

• Dimensions : 1762 × 1134 × 30 mm | Weight : 23.7 kg — compact for roofs with low load-bearing capacity or stressed surfaces

• 36 modules per pallet, 936 pcs per 40' HC — optimized site logistics

Manufacturer's warranties:

• 25 years of equipment

• 30-year linear power guarantee (degradation year 1: 1%; then 0.4%/year — 87.4% at 30 years)

This module is available in variant 470 Wp — Tongwei TWMNH-48HW 470 Wp module — for installations with limited surface area requiring maximum power density.

Areas of application for professionals

This module covers three installation segments with a single module:

Individual residential

• Toiture pente, inclinée ou bac acier — format compact (23,7 kg, 1 762 mm) facilite la manutention mono-opérateur

• Integrated black frame at no extra cost — meeting the requirements of the French Heritage Buildings Authority (ABF) and urban condominiums

• Individual self-consumption with surplus: efficient thermal coefficient = production maintained on hot summer days

Small C&I — Low-rise office

• System voltage 1500 V DC: direct compatibility with the C&I string inverter ranges ( Huawei SUN2000 , Sungrow SG125CX )

• Tolerance 0/+3%: precise string sizing, no fleet downgrade

Flat roofs

• Static load 6000 Pa front face: compatible with steel portal structures

• Dual glass : superior chemical resistance to splashes, no aging backsheet

FAQ — Tongwei TWMNH-48HW 465 Module Wp

What is the difference between the TWMNH-48HW and a standard P-type module in terms of actual production?
N-Type TOPCon technology exhibits a maximum thermal coefficient (Pmax) of -0.28%/°C compared to -0.35% to -0.40% for P-type PERC modules. On a summer day with a cell temperature of 65°C, the power output advantage reaches 4% to 6% in favor of TOPCon—directly measurable in the annual production ratio (PR). The guaranteed linear degradation of 0.4%/year ensures 87.4% of the nominal power output at 30 years.

Is Dual Dual glass compatible with standard fixing structures?
Yes. The TWMNH-48HW module retains an anodized aluminum frame allowing for mounting with standard center/edge clamps ( Dome Solar (K2 Systems, GSE). Its 30 mm thickness and 23.7 kg weight are within normal ranges for residential and C&I structural applications. The certified static load of 6,000 Pa front / 4,000 Pa rear exceeds the requirements for most wind zones in mainland France.

Is this module eligible for the PPE2 scheme or for CRE tenders?
The TWMNH-48HW is certified to IEC 61215 and IEC 61730. The module has valid PPE2 and PPE2V2 certifications.

La boîte de jonction IP68 couvre-t-elle réellement les installations en zone côtière ?
L'IP68 garantit l'étanchéité à l'immersion temporaire. Pour les zones salines (bord de mer < 2 km), le module est certifié IEC 61701 (résistance à la brume saline), ce qui le rend eligible aux sites côtiers sans déclassement de garantie. À vérifier auprès de Tongwei Solar pour les zones d'embruns intensifs (< 500 m du littoral).
