Solar panel TONGWEI - TWMNH-48HW - 470 Wp - NType Topcon

Tongwei TWMNH-48HW 470 Module Wp — N-Type TOPCon, Maximum Power on Constrained Area

Same dimensions 1762 × 1134 mm, 10 Wp Furthermore: the TWMNH-48HW 470 Wp is the installer's choice when every square centimeter counts on the construction site.

470 Wp In a compact format: the figures that make the difference

With the same surface area, the TWMNH-48HW 470 Wp delivers 23.5% module efficiency — or 5 Wp Additional features compared to the 465 Wp variant on the same footprint. This module is the ideal solution for optimizing the layout and structural costs.

STC electrical parameters (470 Wp ) :

• Peak power : 470 Wp — tolerance 0/+3% (no underpowered modules at factory exit)

• Module yield : 23.5% — in the top quartile of residential modules on the market in 2025

• Voc : 36.55V | Isc : 15.95 A | Vmp : 30.80 V | Imp : 15.26 A

• Maximum thermal coefficient Pmax : -0.28%/°C — stable thermal behavior, production maintained on days with strong sunshine

• Maximum system voltage : 1500 V DC — up to 17 modules in series depending on the inverter (calculation to be confirmed by the inverter manufacturer)

• TNC N-Type cell : 96 half-cells [6×16], Tunnel Oxide Passivated Contact technology — world's No. 1 PV cell manufacturer by volume

Priority application areas for the 470 Wp

The power/surface area ratio directs this module towards specific use cases:

Résidentiel surface contrainte (< 30 m²)

• Urban roofs with dormer windows, skylights, or partial shades reduce the usable surface area.

• Rénovation sur combles : nombre de modules limité par la charpente existante — chaque Wc compte

• Self-consumption objective with battery storage ( ATMOCE , FOX ESS , HUAWEI , etc.): maximum power = optimized daily charging

High energy performance houses (NZEB / RE2020)

• Tight sizing imposed by the design office: the 470 Wp allows us to achieve the required kWp/m² ratio without oversizing the surface area

• Combination with a heat pump or thermodynamic water heater ( Thaleos ): the additional power covers peak consumption

Small C&I roof — Commercial premises such as showrooms or low-rise warehouses

• Roof area often reduced by technical equipment (air handling units, vents)

• Construction site carbon footprint: fewer modules for the same power = less transport, less waste

FAQ — Tongwei TWMNH-48HW 470 Module Wp

Is the TWMNH-48HW 470 Wp compatible with micro-inverters or is a string inverter required?
The voltage (Voc) is 36.55 V and the power is 470 Wp are within the compatibility range of recent residential microinverters . For string installations, a Vmp of 30.80 V allows for strings of 16 to 17 modules under 1500 V voltage with Huawei SUN2000-15/20KTL or Sungrow inverters.

What is the maximum number of modules per pallet and what are the transport conditions?
The standard pallet contains 36 modules ; a 40' HC holds 936 pcs (26 pallets). For orders less than one pallet, POwR Connect Delivered in secure packaging on a partial pallet. The weight per module is 23.7 kg — allow for two operators or a pallet jack for unloading.

Is this module suitable for areas with high summer heat (PACA, Occitanie)?
Yes. The maximum thermal coefficient (Pmax) of -0.28%/°C is more favorable than that of P-type PERC modules (-0.35%/°C). At a cell temperature of 70°C (a typical August day in the Provence-Alpes-Côte d'Azur region), the power loss is -12.6% for the TOPCon N-Type compared to -15.75% for PERC—a 3-point increase in efficiency maintained under the most unfavorable conditions. For a 9.4 kWp installation, this represents up to 300 kWh of additional energy saved per year.
