NType TOPCon technology: what it changes in real-world production

NTOPCon (Tunnel Oxide Passivated Contact) technology Jolywood — for which the company owns the intellectual property rights — is based on phosphorus-doped N-type silicon. Verifiable operational gains:

• Zero LID / zero LeTID : no risk of light-induced degradation, unlike P-type PERC cells

• Reduced degradation : −1.00% in year 1, then −0.40%/year — i.e. 87.4% of power guaranteed at 30 years (vs 80% standard on competing P-type modules)

• Thermal coefficient −0.30%/°C : over a day at a cell temperature of 45°C, the power loss is approximately 6%

• Low-light response : production maintained from 200 W/m² — a tangible advantage over installations with suboptimal orientation or exposed to episodes of morning fog

• Bifacial gain : up to +30% production on the back face depending on albedo and guard Ground — to be integrated into PVsyst simulations in structure-based configuration or Flat Roof left

Areas of application for professionals

The JW-HD144N 580 Wp is positioned for medium to high power projects where surface density and mechanical robustness are required:

Small tertiary sector

• Large pitched roofs require a reduced number of modules to achieve 9 to 15 kWp

• White membrane roofs (high albedo): maximized bifacial gain, compatible Mounting systems weighted

Tertiary / C&I

• Rooftop terraces of commercial buildings, logistics warehouses, EV charging platforms

• Structure Dual glass suitable for coastal, humid areas or areas subject to chemical environments (IEC 61701 salt mist, IEC 62716 ammonia)

• Parking canopies : dual-facility usable on light-colored concrete slabs or light-colored surfaces

• Native compatibility with 1500 Vdc multi-string inverters ( Huawei SUN2000, Sungrow SG125CX-P3, SMA ) — Isc 14.36 A to be verified according to MPPT tracker

Facilities at Ground / agrivoltaic

• Vertical bifacial configuration (BIPV or agricultural): wide bifaciality 80% and wind resistance 2400 Pa

• Snow-covered areas: snow load 5400 Pa, zero LID during spring restart

FAQ — Jolywood JW-HD144N 580 Wp

Is the JW-HD144N compatible with Huawei SUN2000 three-phase inverters?
Yes, subject to string validation. With Voc = 51.48 V per module, a string of 28 modules reaches 1441.4 V — below the 1500 Vdc limit. The Isc of 14.36 A should be compared with the maximum MPPT input current of the model Huawei targeted. For the SG125CX-P3 ( Sungrow ), same approach — MPPT channels generally support 2 × Isc in parallel.

What does 80 quote bifaciality mean in concrete terms for a quote?
It expresses the ratio of Pmax rear face to Pmax front face. On a flat roof installation with a white membrane (albedo ~0.6–0.7), the bifacial gain that can be simulated in PVsyst is between 5 and 12%, depending on the guard height and row spacing. This should be systematically integrated under the P50 assumption to refine the LCOE.

What is the warranty period for the JW-HD144N?
Product warranty (materials and labor): 12 years . Linear power warranty: 25 years — 97% at 1 year, 87.4% at 25 years. Guaranteed annual degradation of 0.40%/year after year 1.

Is the module suitable for BIPV or vertical installation?
Yes. The manufacturer's datasheet explicitly lists BIPV applications, vertical installation, snowy areas, high humidity areas, and windy/dusty areas. The structure Dual glass Double reinforced tempered glass is a prerequisite for these uses, and is satisfied here.
