JinkoSolar is represented in stock by the JKM series — monocrystalline modules from 430 to 620 W at 21.5–23.0% efficiency. The number after JKM equals the nameplate rating, and the number before HL gives the whole-cell count: 54HL4R means 108 half-cells in a 1762×1134×30 mm frame, 72HL4 means 144 cells at 2278×1134, and 66HL4M means 132 cells at 2382×1134. Weight runs from 22 kg for the compact format to 32.5 kg for the largest module.
The BDV (and BDVP) suffix marks a bifacial module with rear glass. Six of the eleven items qualify: JKM430N-54HL4R-BDV, JKM555M-72HL4-BDVP, JKM565N, JKM585N, JKM590N and JKM620N-66HL4M-BDV. Monofacial units carry a B or V suffix and, in the large frame, weigh 3–4 kg less: JKM585N-72HL4-V is 27 kg against 31 kg for JKM585N-72HL4-BDV. In the compact 108-cell frame there is no weight penalty at all — both variants are 22 kg.
Open-circuit voltage across the range is 38.6–52.9 V and current at maximum power point 13.27–15.22 A. The current spread is narrow, which makes Jinko modules easy to combine within one frame size. When laying out a string, check Voc against the inverter maximum input voltage rather than against the MPPT operating window.
