This represents the lowest counterparty risk for project financing and is a critical factor for both institutional investors and residential buyers seeking long-term warranty coverage. - **Half-cut cells + 5-busbar architecture** - Splitting cells in half reduces internal resistance and limits shading losses - in a half-cut layout, a partially shaded section only disables half the module rather than the entire string. The 5-busbar design shortens current paths, lowering resistive losses and improving long-term contact reliability. - **1500 V system voltage** - IEC/UL certification for 1500 V DC allows more modules per string compared to standard 1000 V installations. This reduces the number of strings, DC wiring runs, and MPPT inputs required, directly lowering BoS costs and simplifying the DC side of utility-scale and ground-mount system designs. - **Up to 21.17% efficiency - top of PERC segment** - The upper efficiency bound of 21.17% outperforms the peer comparable MWG Mono (19.32%) by nearly 2 percentage points and DMEGC GH400M10T-B48HST (15.48%) by over 5.5 pp. The only peer exceeding this value is Meyer Burger White (21.7%), which occupies a significantly higher price tier as a European-manufactured premium panel. ## Cons - **P-type PERC - higher LID and degradation vs N-type** - PERC cells on a boron-doped P-type substrate exhibit Light-Induced Degradation (LID): PVEL 2025 testing shows 1.5-2.5% power loss in the first 200-500 operating hours. Annual degradation for PERC is 0.6-0.8%/yr versus 0.4-0.5%/yr for N-type TOPCon; after 25 years, PERC retains approximately 82-84% of initial power vs ~85-87% for TOPCon. Jinko's own Tiger Neo (TOPCon) line offers a temperature coefficient of -0.29%/°C vs -0.35%/°C for this series, translating to measurably higher annual yield in high-temperature climates or on heat-absorbing rooftops. - **Monofacial only - no bifacial albedo gain** - The series is monofacial - the rear surface generates no power from reflected irradiance. Modern bifacial modules of the same power class achieve 5-25% additional yield on bright surfaces (white TPO membrane, gravel, concrete), making bifacial alternatives meaningfully more competitive on LCOE for ground-mount and flat-roof applications. ## About this series The Jinko Solar 72 Series has been designed for installations where stable energy production is crucial, even under challenging conditions. The modules utilize a **half-cut** construction and **Mono PERC** monocrystalline technology, which helps to minimize losses and perform better in partial shading - for example, from chimneys, trees, or building elements on the roof. The use of a **multi-busbar architecture** supports more efficient current collection and improves reliability during operation. Another key feature of this series is the **high operating voltage of the system**, which makes it easier to design longer strings and can simplify the DC side of the installation, resulting in a more organized assembly. In practice, this is a solution for investors who want predictable yields throughout the year, even in less sunny conditions and at higher module temperatures. The Jinko Solar 72 Series is suitable for larger residential installations, commercial rooftop installations, and ground-mounted systems, where durability, weather resistance, and easy compatibility with standard inverters are important. ## Notable figures - Efficiency of 19.7% matches the \*\*PERC 0-400W\*\* median - Power density of 196.7 W/m² matches the \*\*PERC 0-400W\*\* median - At -0.37%/°C, hot weather performance is typical for \*\*PERC 0-400W\*\* panels - At 23.5 kg (3.0 kg above \*\*PERC 0-400W\*\* median of 20.5 kg), requires checking roof load capacity - In the top 89% for efficiency among all PERC panels ## Questions ### What is the warranty on Jinko Solar 72 Series panels? The Jinko Solar 72 Series comes with a 10-year product warranty covering material and workmanship defects, along with a 25-year linear power warranty. The manufacturer guarantees that after 25 years the panel will retain at least 80.7% of its rated output. As a Tier 1 manufacturer, Jinko Solar has the financial stability to back these long-term warranty commitments. ### Do Jinko Solar 72 Series panels perform well under partial shading from a chimney or trees? Yes, the 72 Series is specifically designed to handle these conditions. The half-cut cell design splits each cell in two, so shading on one part of the module has a smaller impact on overall output. The multi-busbar architecture further improves current collection and reduces losses. This makes it a strong choice for rooftops with chimneys, dormers, or nearby vegetation. ### What is the wattage of a Jinko Solar 72 Series panel, and is it enough for a home? The maximum rated power of modules in this series is 400 Wp. For a typical single-family home consuming 4,000-6,000 kWh per year, you would generally need 10-16 panels, resulting in a system of 4 to 6.4 kWp. The 72 Series suits both residential rooftop systems and larger commercial roofs where high per-module power output matters. ### Do Jinko Solar 72 Series panels stay efficient in summer when they heat up significantly? The Mono PERC technology combined with the half-cut cell structure helps minimize power losses caused by elevated module temperatures. These panels have a low temperature coefficient, meaning their output degrades less on hot days compared to older polycrystalline modules. The 72 Series is designed for predictable year-round energy yields, including during peak summer irradiance. ### Are Jinko Solar 72 Series panels compatible with standard inverters, and can they be configured in long strings? Yes, one of the key advantages of this series is its high system operating voltage, which allows longer DC strings. This means more panels can be connected to a single MPPT input on the inverter, simplifying wiring and reducing BoS costs. The modules are compatible with standard grid-tied inverters from major brands available on the European market. ### Is Jinko Solar a reliable manufacturer, and where are the 72 Series panels made? Jinko Solar is one of the world's largest PV module manufacturers and holds Tier 1 status according to independent rating agencies. The company is headquartered in China, where the 72 Series modules are produced. Tier 1 classification reflects the manufacturer's financial stability and adherence to strict quality standards - an important factor when considering a 25-year power warranty. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/JS158M72-400W-34e95a85f2e3.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Luxor Solar LX-440M/182-108+GG](https://comparepv.com/panel/luxor-solar-lx-440m-182-108-gg) | 440 W | +50 W, cooler, +3.4 pp | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | -50 W, lighter, +3.3 pp | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | Lighter, +3.3 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | Lighter, +3.3 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/2\*4\*20)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-2-4-20) | 400 W | Lighter, +3.3 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/4\*4\*40)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-4-4-40) | 400 W | Lighter, +3.3 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/2\*4\*19)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19) | 380 W | Lighter, +3.3 pp, +5 yr warranty | | [Jetion JT440SYK(B)](https://comparepv.com/panel/jetion-jt440syk-b) | 440 W | +50 W, cooler, +3.2 pp | | [Jinko Solar JS380M](https://comparepv.com/panel/jinko-solar-js380m) | 380 W | -10 W, -0.5 pp | | [Jinko Solar JS385M](https://comparepv.com/panel/jinko-solar-js385m) | 385 W | -0.3 pp | | [Jinko Solar JS395M](https://comparepv.com/panel/jinko-solar-js395m) | 395 W | +0.2 pp | | [Jinko Solar JS400M](https://comparepv.com/panel/jinko-solar-js400m) | 400 W | +10 W, +1.5 pp | | [Maxeon SPR-MAX7-475](https://comparepv.com/panel/maxeon-spr-max7-475) | 475 W | Cooler, +4.3 pp, +15 yr warranty | | [Maxeon SPR-MAX7-470](https://comparepv.com/panel/maxeon-spr-max7-470) | 470 W | Cooler, +4.0 pp, +15 yr warranty | | [Maxeon SPR-MAX7-465](https://comparepv.com/panel/maxeon-spr-max7-465) | 465 W | Cooler, +3.8 pp, +15 yr warranty | | [Lina Energy LEPV 132 ULTRA PREMIUM BLACK 440Wp (LEPV 440)](https://comparepv.com/panel/lina-energy-lepv-132-ultra-premium-black-440wp-lepv-440) | 440 W | +50 W, cooler, +2.7 pp | --- Source: https://comparepv.com/panel/jinko-solar-js390m Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
