Middle of its segment, weak in heat
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.

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.
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.
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.
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.
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.
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.
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.
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.
- Efficiency of 18.7% is 0.7pp below the PERC 0-400W median (19.4%)
- Power density of 188.1 W/m² is 6.3 W/m² below PERC 0-400W median (194.4 W/m²) - needs more roof space
- -0.42%/°C temperature coefficient - 0.06pp worse than PERC 0-400W median (-0.36%/°C), expect higher hot weather losses
- At 23.5 kg (3.0 kg above PERC 0-400W median of 20.5 kg), requires checking roof load capacity
- In the top 93% for efficiency among all PERC panels
