Middle of its segment, modest efficiency
JS Solar JS210MC150 photovoltaic panels are a high-performance solution based on 210 mm cell technology, which redefines the approach to designing large-scale and rooftop installations. The use of next-generation silicon wafers in combination with an advanced 1/3-cut system allows for exceptional efficiency while simultaneously lowering the module's operating temperature. As a result, this series effectively eliminates the problem of energy losses on hot days, ensuring stable power production throughout the year. A key benefit for the investor is a significant reduction in BOS costs - higher power from a single panel means less demand for mounting structures and faster investment completion time. Innovative Multi-busbar (MBB) technology shortens the electron flow path and increases light absorption, which, combined with high cell packing density, makes these modules some of the most efficient in their class. The JS210MC150 series also stands out for its full resistance to the PID effect and reinforced mechanical structure, which protects the installation against micro-cracks and degradation in harsh weather conditions. This solution is dedicated to professional solar farms and modern enterprises seeking maximum power density and uncompromising durability that goes beyond market standards.

Signals from the data
Commercial, shaded-installations and hot-climate.
Tight roof space, roofs where every square metre has to count and owners who want a long output guarantee.
Bottom 9% of the 390-590 W band, against a median of 21.76%. Ranked 11,769th in the whole database.
Bottom 10% of the 390-590 W band, against a median of 217.6. Ranked 11,712th in the whole database.
Bottom 15% of the 390-590 W band, against a median of 30 yrs.
210mm wafers sliced into thirds (1/3-cut) reduce the working current per sub-cell, lowering resistive losses and operating temperature. The Multi-busbar (MBB) layout shortens electron path length and captures more reflected light, delivering higher energy yield than older half-cut designs.
Higher per-module wattage directly reduces the number of modules, racking structures, DC wiring, and connectors required per kWp. On utility-scale projects ≥1 MWp, this can cut BoS costs by 8–12% compared to prior-generation 380–400 W panels.
The top-bin variant reaches 21.2% module efficiency, exactly matching the peer comparable Trina Solar Vertex Backsheet Monocrystalline Module (510 W, 21.2%). This places the series at the upper end of the M10/G12 PERC market segment.
The manufacturer declares 100% resistance to Potential Induced Degradation — a critical feature in 1500 V DC systems and high-humidity climates. IEC 61215 and IEC 61730 certifications confirmed via the ENF Solar panel directory.
A standard 25-year linear performance warranty aligns with the market norm set by Tier-1 manufacturers such as Trina and JA Solar, providing investors with a predictable degradation curve throughout the entire project financing period.
Yixing JS Solar Co. (est. 2011) does not appear on the BloombergNEF Tier-1 solar module list as of Q1 2026. For project-financed or leased installations, lenders typically require modules from BNEF Tier-1 manufacturers, which may restrict or complicate external financing for projects using this series.
Peer comparable JA Solar JAM60S40 LR (510 W) achieves 23% module efficiency, and Sunlike Solar SKT490~510M12-108D4 reaches 22.93%, while the JS210MC150 tops out at 21.2%. The 1.7–1.8% absolute gap means that, for the same roof or ground footprint, a JS Solar installation will generate measurably less energy than competing N-type TOPCon options.
The series is strictly monofacial (is_bifacial: false), offering no albedo gain from the module's rear side. Bifacial counterparts such as the Trina Vertex S+ Bifacial report 5–20% additional yield depending on ground albedo, making the JS210MC150 less competitive for ground-mount and agrivoltaic installations.
- At 20.3% efficiency, this panel is 1.5pp below the database median of 21.8%
- Power density of 203.3 W/m² is 14.8 W/m² below database median (218.1 W/m²) - needs more roof space
- Temperature coefficient of -0.34%/°C is 0.04pp worse than database median (-0.30%/°C) - higher losses in summer heat
- In the top 84% for efficiency among all N-type panels
