The 210R-120 is a full black bifacial module built for roofs that are seen as well as used. 120 half-cut cells from 182×93.4mm N-type TOPCon wafers sit in a 6×20 layout inside a 1955×1134×30mm frame, giving 21.20% to 22.55% module efficiency across seven power bins from 470W to 500W. Half-cut cells cut resistive loss and hold output stable under partial shading. Colourless embossed glass on the front and black mesh semi-tempered glass on the rear create the uniform black finish, and the double glass construction carries a 1500V DC system rating. MC4-compatible connectors and symmetrical 4mm² cables keep field wiring fast.

All-black finish: black frame, black rear glass and black cell surface for a uniform look on visible roofs and facades.
N-type TOPCon cells: 120 half-cut 182×93.4mm cells, 21.20% to 22.55% module efficiency.
Double glass construction: 2.0mm glass on both faces, no polymer backsheet to degrade.
1500V DC maximum system voltage, 30A maximum series fuse rating.
MC4-compatible IP68 connectors and symmetrical 4mm² cables, 1100mm per side.
Seven power bins (470W to 500W, 5W steps) on one 1955×1134×30mm footprint.
Higher yield per square metre: up to 22.55% efficiency means more power from the same limited roof area, which is usually the binding constraint on hotel and commercial buildings.
Extra energy from the rear face: on elevated, high-albedo installations the bifacial rear adds up to 15% to total production.
Less shading loss: half-cut cell layout keeps the unaffected strings producing when part of the module is shaded.
Better high-temperature behaviour: N-type TOPCon cells hold output steadier than P-type PERC through midday heat; NMOT data is published for all seven bins.
Aesthetic payback: full black modules command a premium on visible architecture, so the array sells the building as well as powering it.
Hotel and resort rooftops, where the array is visible from upper floors and terraces.
Commercial building facades and visible roof planes in city-centre projects.
High-end residential and villa installations where roof aesthetics drive approval.
Carports, pergolas and canopy structures where the rear face is exposed and bifacial gain can be captured.
Clean the glass with soft water and a non-abrasive brush in the early morning or evening; avoid thermal shock on hot glass.
Inspect connectors, cables and clamps annually for abrasion, water ingress and loosening.
Keep vegetation and new construction away from the array edge — shading losses compound across a string.

LCSOLAR has manufactured PV modules since 2005 and runs a 3GW fully automated module line in Qingyang, Jiangyin. The line runs under ISO 9001, ISO 14001 and ISO 45001 management systems, and modules are type-tested to TUV and CE requirements. Every full black module ships with factory flash test data, and OEM labelling, packaging and frame colour are available for distributor programmes. Technical support and container-load shipping are handled from the same factory, so the team that builds the module also answers the question.
Q:What power bins does the 210R-120 come in?
A: Seven bins — 470 W, 475 W, 480 W, 485 W, 490 W, 495 W and 500 W. All seven share one 1955 × 1134 × 30 mm footprint and the same electrical layout, so a single racking and stringing design covers the whole range.
Q:How efficient is it?
A: 21.20% at 470 W rising to 22.55% at 500 W, from 120 half-cut 182 × 93.4 mm N-type TOPCon cells. That is roughly one efficiency class above the PERC modules in the same footprint, which matters when roof area is the constraint. See the full N-type TOPCon solar module range for other formats.
Q:Does the full black finish reduce output compared with a standard module?
A: No. The finish changes the frame and the rear glass, not the cells or their efficiency. The 470-500 W rating and 21.20-22.55% efficiency are measured under the same STC conditions as any other 210R-120 module.
Q:What is the warranty?
A: 15-year product and workmanship warranty and a [[30]]-year linear performance warranty, with maximum 1.0% first-year degradation and 0.4% per year thereafter. Current certificate wording is being standardised across the range — ask for the warranty sheet with your quotation.
Q:It is bifacial — what happens if my roof has a dark membrane and the rear is enclosed?
A:The module works as a standard monofacial module at nameplate power. The up-to-15% rear-side gain applies when the rear face is exposed to reflected light — typically on elevated structures, carports, canopies and ground mount with light-coloured ground cover. On an enclosed roof the full black finish is the main benefit, not the bifacial gain.
