It delivers \u003cstrong\u003e23 % module efficiency\u003c\/strong\u003e from 108 laser-traceable half-cut cells in a double-glass, full-black format measuring 1,762 × 1,134 × 30 mm and weighing 22 kg. N-type TOPCon cell technology gives this panel a significant advantage over standard P-type PERC panels: \u003cstrong\u003evirtually zero light-induced degradation (LID)\u003c\/strong\u003e, a superior temperature coefficient of \u003cstrong\u003e−0.29 %\/°C\u003c\/strong\u003e, and better energy yield in overcast and low-irradiance conditions — all of which matter in the UK climate.

There is no silver frame, no white backsheet and no visible silver interconnects. The result is a uniform, low-contrast appearance that blends with dark tile roofs (slate, anthracite concrete, dark clay) and suits architectural installations where the solar array should be visually unobtrusive. The all-black design also helps in snow shedding: the darker surface absorbs more heat, accelerating snow melt and reducing downtime from snow coverage in winter months.\u003c\/div\u003e\n\u003cdiv style=\"margin-top: 8px;\"\u003e\n\u003cspan style=\"display: inline-block; background: #008377; color: #fff; border-radius: 20px; padding: 3px 11px; font-size: 13px; font-weight: bold; letter-spacing: .02em; margin: 2px 4px 2px 0; white-space: nowrap;\"\u003eFull all-black\u003c\/span\u003e\u003cspan style=\"display: inline-block; background: #008377; color: #fff; border-radius: 20px; padding: 3px 11px; font-size: 13px; font-weight: bold; letter-spacing: .02em; margin: 2px 4px 2px 0; white-space: nowrap;\"\u003eBlack frame + cells + rear glass\u003c\/span\u003e\u003cspan style=\"display: inline-block; background: #008377; color: #fff; border-radius: 20px; padding: 3px 11px; font-size: 13px; font-weight: bold; letter-spacing: .02em; margin: 2px 4px 2px 0; white-space: nowrap;\"\u003eSnow shedding benefit\u003c\/span\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; gap: 14px; align-items: flex-start; padding: 14px 16px; background: #f8f8f8; border-left: 4px solid #008377; border-radius: 0 6px 6px 0; margin-bottom: 8px;\"\u003e\n\u003cdiv style=\"flex-shrink: 0; width: 28px; height: 28px; background: #008377; border-radius: 50%; display: flex; align-items: center; justify-content: center;\"\u003e\u003csvg width=\"13\" height=\"13\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"#fff\" stroke-width=\"3\"\u003e\u003cpolyline points=\"20 6 9 17 4 12\"\u003e\u003c\/polyline\u003e\u003c\/svg\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1;\"\u003e\n\u003cdiv style=\"font-size: 15px; font-weight: bold; color: #005c54; margin-bottom: 4px;\"\u003eLR Laser Traceability — Full Supply Chain Transparency\u003c\/div\u003e\n\u003cdiv style=\"font-size: 15px; color: #444; line-height: 1.6;\"\u003eThe ‘LR’ designation indicates that every individual cell in this module is \u003cstrong\u003elaser-marked with a unique traceable identifier\u003c\/strong\u003e.

A \u003cstrong\u003ebifacial\u003c\/strong\u003e panel has a transparent rear face that also captures reflected light from behind the panel. For a \u003cstrong\u003epitched UK roof\u003c\/strong\u003e, where the rear of the panel faces the roof surface with very little reflected light, bifacial rear-side gain is negligible — typically less than 2 % in most residential pitch-roof conditions. Bifacial panels are most beneficial in ground-mounted systems on light-coloured ground or elevated racking where reflected albedo light can reach the rear. For a standard UK rooftop installation, the monofacial double-glass version offers the same front-side performance with full-black aesthetics.\u003c\/div\u003e\n\u003c\/details\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"border: 1px solid #cde3e1; border-radius: 8px; margin-bottom: 10px; overflow: hidden;\"\u003e\n\u003cdetails\u003e\n\u003csummary style=\"padding: 14px 18px; font-size: 15px; font-weight: bold; color: #005c54; cursor: pointer; list-style: none; display: flex; align-items: center; justify-content: space-between; background: #f5fbfa;\"\u003e\u003cspan\u003eWhat is ‘LR traceable’ and does it affect panel performance?\u003c\/span\u003e\u003csvg width=\"18\" height=\"18\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"#008377\" stroke-width=\"2.5\"\u003e\u003cpolyline points=\"6 9 12 15 18 9\"\u003e\u003c\/polyline\u003e\u003c\/svg\u003e\u003c\/summary\u003e\n\u003cdiv style=\"padding: 14px 18px 16px; font-size: 15px; color: #444; line-height: 1.65; border-top: 1px solid #cde3e1; background: #fff;\"\u003eLR stands for \u003cstrong\u003eLaser-traceable\u003c\/strong\u003e. Each individual cell in the module has a unique laser-etched identifier that allows it to be traced back through the manufacturing supply chain. This does not affect electrical performance. Its importance is in supply chain transparency: it enables verification of cell origin and quality history, and supports compliance with ethical sourcing and modern slavery policies that are increasingly required by commercial project developers and councils. For residential customers, LR traceability is a quality indicator rather than a performance feature.\u003c\/div\u003e\n\u003c\/details\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"border: 1px solid #cde3e1; border-radius: 8px; margin-bottom: 10px; overflow: hidden;\"\u003e\n\u003cdetails\u003e\n\u003csummary style=\"padding: 14px 18px; font-size: 15px; font-weight: bold; color: #005c54; cursor: pointer; list-style: none; display: flex; align-items: center; justify-content: space-between; background: #f5fbfa;\"\u003e\u003cspan\u003eWill this panel work well on a south-facing UK roof in overcast conditions?\u003c\/span\u003e\u003csvg width=\"18\" height=\"18\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"#008377\" stroke-width=\"2.5\"\u003e\u003cpolyline points=\"6 9 12 15 18 9\"\u003e\u003c\/polyline\u003e\u003c\/svg\u003e\u003c\/summary\u003e\n\u003cdiv style=\"padding: 14px 18px 16px; font-size: 15px; color: #444; line-height: 1.65; border-top: 1px solid #cde3e1; background: #fff;\"\u003eYes — and this is one of the primary reasons to choose N-type TOPCon over standard PERC. N-type cells have an enhanced infrared (IR) spectral response, which means they continue to generate power more efficiently when irradiance is low (overcast skies, early morning, late afternoon). In a UK context, a significant proportion of annual energy yield comes from these low-irradiance conditions, particularly from October to March. The \u003cstrong\u003e−0.29 %\/°C temperature coefficient\u003c\/strong\u003e also means less power is lost on hot summer days, boosting performance in the warm months relative to PERC panels.\u003c\/div\u003e\n\u003c\/details\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"border: 1px solid #cde3e1; border-radius: 8px; margin-bottom: 10px; overflow: hidden;\"\u003e\n\u003cdetails\u003e\n\u003csummary style=\"padding: 14px 18px; font-size: 15px; font-weight: bold; color: #005c54; cursor: pointer; list-style: none; display: flex; align-items: center; justify-content: space-between; background: #f5fbfa;\"\u003e\u003cspan\u003eWhat is the difference between the JAM54D40 and JAM54D41 series?\u003c\/span\u003e\u003csvg width=\"18\" height=\"18\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"#008377\" stroke-width=\"2.5\"\u003e\u003cpolyline points=\"6 9 12 15 18 9\"\u003e\u003c\/polyline\u003e\u003c\/svg\u003e\u003c\/summary\u003e\n\u003cdiv style=\"padding: 14px 18px 16px; font-size: 15px; color: #444; line-height: 1.65; border-top: 1px solid #cde3e1; background: #fff;\"\u003eBoth are JA Solar DeepBlue 4.0 series N-type TOPCon modules in the same physical format.

Each panel is 1.762 m × 1.134 m = 2.0 m². In portrait orientation (1.762 m tall), two columns of two panels (4 panels) fit comfortably with standard mounting clearances. In landscape orientation (1.134 m tall), three rows of two panels (6 panels) is a common configuration. Six panels × 460 W = 2,760 W peak — a typical UK residential 2.76 kWp system.
