Jinko Bifacial vs Monofacial Solar Panel: Two 460 W Modules, One Frame
A bifacial panel collects light on both faces; a mono-facial panel collects it on the front only. Buyers ask which to choose, and the fair way to answer is to compare two modules that differ in nothing else. Jinko lists exactly that pair: the bifacial JKM460N-48HL4M-BDV-Z2 and the mono-facial JKM460N-48HL4M-DV-Z4, both N-type, both 460 W, both in the same frame. This page reads their two records side by side. The front-side figures turn out almost identical, which is the useful finding: at this size the choice is about where the panel is mounted, not about what the label says.

What is identical on the two records
The bifacial 48HL4M-BDV-Z2 is rated 460 W at a module efficiency of 23.02 %, and the mono-facial 48HL4M-DV-Z4 is rated 460 W at a module efficiency of 23.02 %. Each has 96 cells (48×2) of N-type mono-crystalline silicon in a 1762×1134×30 mm frame. Each weighs 24.0 kg. Both records list 2.0 mm anti-reflection front glass, 2.0 mm heat-strengthened back glass, an anodized aluminium alloy frame and an IP68 junction box, and both give a temperature coefficient of Pmax of -0.29 %/°C.
The electrical rows that differ
The bifacial 48HL4M-BDV-Z2 has a Voc of 36.53 V and a Vmpp of 31.00 V, with an Impp of 14.84 A and an Isc of 15.75 A. The mono-facial 48HL4M-DV-Z4 has a Voc of 36.25 V and a Vmpp of 30.51 V, with an Impp of 15.08 A and an Isc of 15.83 A. The gaps are small, but a string is sized from the exact module, so take the figures of the one you order rather than assuming the other's.
What the bifacial record does not state
The 48HL4M-BDV-Z2 record we hold gives no bifaciality coefficient and no rear-side power figure, so this page states none. How much the rear face adds depends on the surface below the array and the height of the mounting, and neither is a property of the panel. Treat the rated 460 W as the figure to design with, and any rear-side contribution as a result of the site.
Which one for which roof
Mounted flat against a pitched roof or a few centimetres above a membrane, the rear face of a panel receives almost no light, and the mono-facial 48HL4M-DV-Z4 does the same job. Its record also states a 30 A maximum series fuse rating, a 1500 VDC maximum system voltage and an operating range of -40 to +70 °C. On a raised frame, a ground mount, a pergola or a carport above pale gravel, concrete or sand, the bifacial 48HL4M-BDV-Z2 has a rear face to put to work.
Warranty and price
The bifacial 48HL4M-BDV-Z2 record states 15 years of product warranty and 30 years of performance warranty; the mono-facial 48HL4M-DV-Z4 record states 15 years of product warranty and 30 years of performance warranty. Both are priced at USD 0.169 per watt of rated power, and both are 460 W, so the two cost the same. Neither the warranty nor the price is a reason to prefer one face over the other.
The models in this comparison
Winner
The bifacial 48HL4M-BDV-Z2 for raised, ground-mounted or carport arrays over a bright surface; the mono-facial 48HL4M-DV-Z4 for panels fixed close to a roof.
Conclusion
On the front face these are the same panel: 460 W, 23.02 % module efficiency, 24.0 kg, the same frame, the same glass and the same warranty, at the same price. The bifacial 48HL4M-BDV-Z2 adds a rear face that can work when light reaches it; the mono-facial 48HL4M-DV-Z4 is the plain choice when nothing reaches the back. Decide from the mounting, and read the electrical rows of the one you pick when sizing strings, because they are close but not equal.
