Jinko 450 W vs 500 W Solar Panel: Frame Length, Weight and String Voltage
The 450 W and the 500 W are the two rooftop sizes in the Jinko range, and they are closer relatives than the fifty watts suggest. Both are N-type bifacial dual-glass modules of the same width; the 500 W simply carries one more row of cells. This page compares the JKM450N-48HL4M-BDV-Z2 with the JKM500N-54HL4M-BDV-F1 from their two records. The efficiency is practically the same, so the decision is not about which panel is better engineered. It is about which length fits the roof, which weight the installer wants to carry and which voltage suits the inverter.

Power and efficiency
The 48HL4M-BDV-Z2 is rated 450 W at a module efficiency of 22.52 %. The 54HL4M-BDV-F1 is rated 500 W at a module efficiency of 22.48 %. Both records give a power tolerance of 0 to +3 %. The two efficiencies are within a few hundredths of a point of each other, which says the extra fifty watts come from extra area and not from a different cell.
Size and weight
The 48HL4M-BDV-Z2 has 96 cells (48×2) in a 1762×1134×30 mm frame and weighs 24.0 kg. The 54HL4M-BDV-F1 has 108 cells in a 1961×1134×30 mm frame and weighs 27.0 kg. The width and the frame depth are the same, so the two use the same rail spacing across the panel; only the length changes. Both records list 2.0 mm anti-reflection front glass and 2.0 mm heat-strengthened back glass, and both pack 37 panels to a pallet.
String voltage
The 48HL4M-BDV-Z2 has a Voc of 36.19 V and a Vmpp of 30.53 V, with an Impp of 14.74 A and an Isc of 15.65 A. The 54HL4M-BDV-F1 has a Voc of 40.38 V and a Vmpp of 33.95 V, with an Impp of 14.73 A and an Isc of 15.63 A. The currents are the same to within a few hundredths of an amp; the voltage is what grows with the extra cells. An inverter input that takes one of them on current takes the other, and the number of panels per string is set by the voltage.
Which one for which roof
A roof face cut up by a water tank, a parapet or a stair core often takes a shorter panel where a longer one would overhang, and the 48HL4M-BDV-Z2 is the shorter of the two. It is also the lighter to lift. A long uninterrupted face is quicker to fill with the 54HL4M-BDV-F1, because each panel placed, clamped and connected carries more power. Measure the clear length available before choosing; the width is not a deciding factor because it is shared.
Warranty and price
The 48HL4M-BDV-Z2 record states 15 years of product warranty and 30 years of performance warranty, and the 54HL4M-BDV-F1 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. The bigger panel therefore costs more per piece and the same per watt.
The models in this comparison
Winner
The 450 W 48HL4M-BDV-Z2 for short or interrupted roof faces and lighter handling; the 500 W 54HL4M-BDV-F1 for long clear runs where fewer panels are wanted.
Conclusion
Neither panel is the more efficient one in any way a roof would notice. The 450 W 48HL4M-BDV-Z2 is shorter and lighter, and suits a roof broken up by obstacles or one where each panel is carried up by hand. The 500 W 54HL4M-BDV-F1 puts more power behind each set of clamps and each connector pair. Both cost USD 0.169 per watt of rated power on this store, so a kilowatt of either costs the same, and the same warranty covers both.
