The Jinko Solar 72 Series polycrystalline modules are 72-cell modules designed for stable energy production in typical rooftop and ground-mounted conditions, even when weather is unfavorable. The use of multi-busbar cells (multi-busbar technology) improves current flow and reduces losses, resulting in better performance in real-world installations. A key feature is the high PID resistance, which makes it easier to maintain parameters over the long term, especially in demanding system configurations. The modules utilize high-transmittance glass with an anti-reflective coating, which supports energy generation in low-light conditions and during transitional periods. In practice, this series solves the problem of reduced production on cloudy days and in harsh environments - this is confirmed by resistance to saline fog and ammonia. Furthermore, the design is designed to withstand wind and snow loads, making it a good choice for investors who expect mechanical durability in Polish conditions. This series is suitable for homes, businesses, and smaller farms, where reliability is important without paying a premium for high-end solutions.

What owners get
TÜV NORD certified: salt mist & ammonia resistance

Modules passed independent TÜV NORD testing confirming resistance to salt mist and ammonia corrosion, making them suitable for coastal and agricultural installations without risk of corrosion-induced degradation in aggressive environments.

PID-free (85°C/85% RH)

The series is certified PID-free under 85°C/85% RH conditions — the manufacturer confirms zero power loss from potential-induced degradation, a key advantage in high-voltage string configurations (1000 V DC).

Mechanical loading: 2400 Pa wind / 5400 Pa snow

Certified mechanical resistance to 2400 Pa wind load and 5400 Pa snow load ensures long-term structural integrity under harsh climatic conditions, including heavy-snowfall mountain regions.

JinkoSolar #1 Bloomberg BNEF bankability 2026

JinkoSolar holds the #1 position in the Bloomberg BNEF Bankability Report (Q1 2026) as the only manufacturer achieving 100% bankability, minimizing investment risk and facilitating project financing from lending institutions.

Positive power tolerance 0/+3%

A guaranteed positive power tolerance of 0/+3% ensures every delivered module meets or exceeds its nameplate rating (e.g., minimum 310 Wp for JKM310P-72), eliminating the risk of undersized system design.

Trade-offs
Series discontinued since 2020

The series has been officially out of regular distribution since approximately 2020. Availability of spare parts (junction boxes, frames), service support, and compatible modules for system expansion is severely limited or unavailable.

Efficiency 17% — lowest among peer comparables

Maximum efficiency of 17% is 2.8–6.2 percentage points below peer comparables at equivalent power ratings: Waaree ARKA (19.81%), Techwise Micro Sun (21.12%), and JA Solar Monocrystalline80 (23.15%). On the same roof area, the system delivers 16–36% less peak power.

Legacy polycrystalline cell technology

Poly-PERC has been superseded by mono-PERC, half-cut, and TOPCon cell technologies since approximately 2018–2020. A higher temperature coefficient and weaker low-irradiance performance versus mono result in an estimated 3–5% lower annual energy yield at the same Pnom, directly increasing system LCOE.

Common questions

6 answered
Is the Jinko Solar 72 Series Polycrystalline still available for purchase?
The Jinko Solar 72 Series Polycrystalline has been discontinued and is no longer in regular production. Some units may still be available through distributors with existing inventory, but consistent supply cannot be expected. Customers planning a new PV installation are advised to consider current Jinko Solar module lines with active production, full manufacturer support, and up-to-date certifications.
What warranty does the Jinko Solar 72 Series Polycrystalline come with?
Jinko Solar offered a 10-year product warranty covering material and workmanship defects, plus a 25-year linear power output warranty. The power warranty guarantees that modules retain a specified minimum percentage of their 330 Wp rated output over time. Both warranties remain valid provided the modules are installed and operated in accordance with Jinko Solar's technical documentation and mounting guidelines.
What is multi busbar technology and why does it matter in the Jinko Solar 72 Series?
Multi busbar (MBB) technology replaces a few wide busbars with multiple thinner ones across each PERC cell. In the 72 Series, MBB shortens the current path, reduces resistive losses, and improves cell resistance to microcracks. The practical result is a higher energy yield for the same module footprint and better long-term reliability compared to conventional 3- or 4-busbar designs.
How does the Jinko Solar 72 Series perform in overcast and low-light conditions?
The 72 Series uses high-transmission glass with an anti-reflective coating, which improves light absorption at low irradiance angles and under diffuse lighting. This enables meaningful power output on cloudy days — an important factor in Poland and Central Europe, where a significant portion of annual energy yield comes from overcast sky conditions during spring and autumn months.
Can the Jinko Solar 72 Series modules handle heavy snow loads and strong winds in Polish conditions?
Yes. The 72 Series frame and glass construction is engineered to withstand the mechanical loads from wind pressure and snow accumulation typical of rooftop and ground-mount installations in Central European climates. The reinforced aluminum frame and tempered glass maintain structural integrity under winter conditions common in Poland, making these modules a reliable choice for year-round outdoor deployment.
Are the Jinko Solar 72 Series Polycrystalline modules bifacial or monofacial?
The Jinko Solar 72 Series Polycrystalline modules are monofacial — they generate power only from the front surface and do not incorporate bifacial technology. For installations where reflected irradiance from a light-colored surface (white gravel, roofing membrane) could be captured, newer Jinko Solar bifacial modules would deliver a higher energy yield and improved LCOE. The 72 Series remains well-suited for standard rooftop and small ground-mount systems.
