What is the JAM54D41-430-455/LB (Black Module, ฉบับประกัน 25 ปี)?
- Power per panel: 430 / 435 / 440 / 445 / 450 / 455 W at 0~+3% tolerance — the residential power band
- Module efficiency: 21.5–22.8%, with the 455W bin at 22.8%, which is high for a 108-cell format
- Cell technology: n-type TOPCon (n-Bycium+ 16BB, MBB half-cell, mono), 108 cells in a 6×18 layout, cell efficiency up to 26%
- Size and weight: 1762±2 × 1134±2 × 30±1 mm at just 22 kg — noticeably easier to carry up a villa roof than project-scale modules
- Warranty per the 25y datasheet: 25-year product warranty plus 30-year linear output warranty (1% first year, then 0.4% per year)
The JA Solar JAM54D41 LB Black 455W is the full-black, dual-glass n-type TOPCon module in the DeepBlue 4.0 Pro series, built for houses and pool villas where the owner cares about how the roof looks as much as what it produces. What separates it from its siblings is the warranty: the 25y datasheet states a 25-year product warranty alongside the 30-year linear output warranty. It is the module our engineering team reaches for when designing arrays on Phuket villa roofs, which usually consist of several short planes facing different directions. This page explains what each datasheet line actually means once the panels are on your roof. To size a system first, use the calculator, then see what our services include.
What is the JAM54D41 LB Black, and how does it differ from the project-scale models?
This module uses n-type TOPCon n-Bycium+ 16BB half-cells — 108 of them in a 6×18 layout — on a 1762 × 1134 × 30 mm frame weighing 22 kg, rated 430–455 W with module efficiency of 21.5–22.8%. The 1762 mm length is the whole point: most villa and house roofs are made of short planes at several orientations, and a shorter module lays out more cleanly, wastes less edge space, and sometimes yields more total installed capacity than forcing long panels into the same area. The all-black finish also sits far better against dark tile roofs and resort-style architecture than a silver-framed module. Electrically, the 455W bin gives Voc 40.50 V and Isc 14.42 A; the lower per-panel voltage of a 108-cell module usually lets you place more panels in a string before reaching the inverter's voltage ceiling. Note that bifaciality here is specified as 80% ±10%, a wider tolerance than the project models carry, so rear-side gain should be treated as a bonus rather than a guaranteed number in a yield estimate. Compare it with the rest of our hardware on the equipment page, and if you also want power during outages, read about a hybrid with battery backup. Every figure here comes from the Global-EN datasheet, which the manufacturer states is subject to technical change, so we re-verify the current revision before designing.
Highlights from the datasheet
- 25-year product warranty on the 25y datasheet: this is the genuine selling point — product cover that matches the lifespan most owners expect from a solar system, where the project-oriented models in the same series state a shorter product term
- 22.8% module efficiency on a 108-cell panel: you are not trading away output to get a shorter, better-looking, easier-to-install module
- Full-black finish: frame and surface in the same tone give a flat, uninterrupted roof appearance against dark tiles — which matters to villa owners and to estates with visual guidelines
- 22 kg per module: significantly lighter than project modules, which makes handling on pitched roofs and narrow access routes safer and reduces the added load on an existing roof structure
- Temperature coefficient of −0.290 %/°C: identical to the large modules in the series, so choosing the residential format costs you nothing in hot-roof behaviour — the normal condition in Phuket almost every day
- 1% first-year and 0.4% annual degradation over 30 years: this is what determines output in the later years of the system, and it is a far better basis for judging value than day-one wattage
- Bifaciality of 80% ±10%: a wider tolerance band than the project models, so we exclude rear-side gain from the guaranteed yield figure in a residential proposal and treat it as upside where the site allows

Why this model suits Phuket
- Villa roofs have many short planes: at 1762 mm the module lays out more cleanly on small roof faces, wastes less edge space, and gives more flexibility when planes face different directions
- Owners who care how the house looks: a full-black array blends with dark tiles and resort architecture, which for villa clients matters as much as the electricity bill
- Hot, humid conditions all year: the −0.290 %/°C coefficient limits hot-roof losses, and the dual-glass construction suits the island's permanently high humidity
- Real-world handling on a house roof: at 22 kg per module, crews work more safely on pitched roofs and narrow access routes than they can with project-scale panels
Who it suits
- Pool villa owners: want a full-black array that does not spoil the look of the property, with the longest product warranty term of the models we document
- Standard family homes: modest roof area where the goal is to fit as much capacity as possible using a module that lays out flexibly
- Holiday rental villas: air-conditioning and pool pumps run through daylight hours, and owners usually want an installation that photographs well for listings
- Roofs with limited load capacity: at 22 kg per module the added structural load is clearly lower than with project-scale panels
- Buyers for whom warranty term is the deciding factor: if product warranty length drives the decision, this is the model in the range that answers it directly
Summary
The JAM54D41 LB Black 455W is a full-black n-type TOPCon module that suits Phuket houses and pool villas well: up to 22.8% module efficiency, just 22 kg per panel, a −0.290 %/°C temperature coefficient, and a 25-year product plus 30-year linear output warranty per the 25y datasheet. Good panels only deliver their full value with correct orientation planning, string design and inverter matching — work our engineers and installers handle, including the PEA permits.
