The Jinko Solar 72+ Series has been designed for installations where maximizing energy production from a limited area is crucial - particularly on the roofs of warehouses, storage facilities, and commercial buildings, as well as in larger ground-mounted systems. The use of more advanced module construction techniques - such as half-cut cell layouts and multi-busbar connections - effectively improves performance under partial shading and reduces losses due to microcracks or differences between cells. This translates to more predictable energy yields in the Polish climate, even on cloudy days.

In practice, it stands out due to: improved performance in low-light conditions, higher resistance to degradation and thermal stress, more stable performance under shading, and greater compatibility with modern inverters and optimization systems. The 72+ Series is a good choice for investors who want to minimize the risk of power loss over time and achieve a solid energy balance without paying a premium for typical high-end solutions.

What owners get
Jinko Solar – BNEF #1 bankability

JinkoSolar is the only PV manufacturer to achieve 100% bankability in BloombergNEF's survey for 10 consecutive years (2025 data). In 2025, the company shipped 86.8 GW of modules, ranking first in global sales for the seventh consecutive time. For bank-financed and institutionally funded projects, this is one of the most critical supplier selection criteria.

Certified mechanical durability

The 72+ Series modules carry IEC 61215 and IEC 61730 certifications, with verified resistance to wind load (2,400 Pa) and snow load (5,400 Pa). The IP67-rated junction box provides robust weatherproofing. These ratings meet the requirements of installations across Central European climates, including high-snowfall zones.

PERC half-cut cells + multi-busbar

Half-cut cell architecture reduces per-cell current by approximately 50%, lowering resistive losses and mitigating the impact of microcracks. Multi-busbar interconnection further improves performance under partial shading conditions — a meaningful advantage in frequently overcast climates.

25-year linear power warranty

The manufacturer guarantees linear power degradation over 25 years — consistent with top-tier market standards during the production period (2014–2019). For systems sourced from original deliveries, several years of active power output warranty coverage remain in effect.

Trade-offs
Discontinued series (since 2019)

JinkoSolar ended production of the 72+ Series in 2019. Module availability is limited to remaining distributor stock or the secondary market. Active manufacturer technical support for this series is no longer provided, and sourcing replacement modules in the event of a failure is significantly constrained.

Efficiency well below peer comparables

Maximum efficiency of 19.23% trails direct peers at the same 375 Wp rating by 0.77–2.07 percentage points: Boviet Solar VEGA (20.00%), ENCOR EC (20.59%), and JS Solar JSHC166M120 (21.30%). Achieving the same peak power output requires proportionally more roof or ground area.

Monofacial only — no bifacial gain

The 72+ Series has no bifacial variant available. Modern bifacial modules in the same power class generate 5–15% additional annual yield from ground-reflected irradiance, representing a tangible loss in annual energy production compared with current market alternatives.

10-year product warranty — below current standard

The workmanship warranty is 10 years. Since approximately 2022, the dominant Tier-1 market standard has shifted to 12–15 years (e.g., Jinko Tiger Neo: 12 years). For modules from original 2018–2019 deliveries, the effective product warranty expires as early as 2028–2029.

Common questions

6 answered
Is the Jinko Solar 72+ Series still available for purchase?
The Jinko Solar 72+ Series has been discontinued and is no longer actively distributed by Jinko Solar. Limited stock may still be found at some distributors, but availability cannot be guaranteed. Buyers are advised to consider newer Jinko Solar series based on TOPCon technology, which offer higher efficiency and longer warranties.
What warranty does Jinko Solar offer on the 72+ Series panels?
Jinko Solar provided a 10-year product warranty covering defects in materials and workmanship, along with a 25-year linear power output warranty. After 25 years the module is guaranteed to retain approximately 80–83% of its rated power. The warranty remains valid even after series discontinuation, provided proof of purchase is retained.
Does the PERC cell technology in the Jinko 72+ panels improve performance on overcast days?
Yes. PERC (Passivated Emitter and Rear Cell) technology adds a passivation layer on the rear side of each cell, reflecting unabsorbed photons back for a second absorption attempt. This improves low-light performance under diffuse irradiance conditions common in Central European climates, yielding measurably higher energy output on cloudy days compared to standard BSF cells.
What are the dimensions and weight of the Jinko Solar 72+ 375 Wp panel, and can it be installed on a pitched roof?
The 72+ Series 375 Wp modules measure approximately 1755 × 1038 mm and weigh around 20–21 kg. This is a standard commercial 72-cell format compatible with typical rafter spacing. Pitched-roof installation is technically feasible, but given the panel size and weight a dedicated aluminum racking system and a minimum two-person crew are strongly recommended.
Do the half-cut cells in the Jinko 72+ Series improve shading tolerance?
Yes. The half-cut cell design splits each cell in two, effectively dividing the module into two electrically independent strings. Partial shading on one string — from a chimney or dormer, for example — reduces output only in that section rather than across the entire module. Combined with multi-busbar interconnection, this minimizes shading losses and reduces the impact of microcracks on overall system performance.
Are Jinko Solar 72+ 375 Wp panels compatible with string inverters available on the Polish market?
Yes. The open-circuit voltage (Voc) of the 72+ Series modules is approximately 45–49 V, which falls within the MPPT input range of string inverters from brands commonly available in Poland, including SMA, Fronius, Huawei, and Sofar. Always verify the exact Voc and short-circuit current (Isc) values from the datasheet against the inverter's maximum input specifications before sizing the system.
