**N-type TOPCon cells** - TOPCon technology reduces LID/LeTID degradation and improves high-temperature performance compared to older PERC cells, resulting in more stable energy yield over a 25-30 year installation lifetime. - **Bifacial + dual-glass construction** - The module captures light reflected off the ground (bifacial) combined with a glass-glass (dual-glass) build, increasing resistance to moisture and micro-cracking - especially relevant for ground-mount systems, bright rooftops, and elevated racking. - **30-year power warranty** - The manufacturer offers a 30-year linear power warranty alongside a 25-year product warranty - longer than the standard 25 years typical of many peer comparables in the 680-700 Wp N-type bifacial segment. - **Efficiency up to 22.53% in the premium class** - Peak efficiency of 22.53% matches the VSUN N-132BMH-DG (22.53%) and exceeds the Sunket SKT680~700M12-132D5 (22.5%), placing the module in the upper half of comparable products in the 680-700 Wp segment. - **Framed version simplifies installation** - Unlike many frameless dual-glass modules, the Framed N132 version allows the use of standard, widely available mounting systems common in Poland, without requiring specialized clamps for frameless modules. ## Cons - **No confirmed BNEF Tier 1 status** - Mysolar USA does not appear on BloombergNEF's Tier 1 lists for Q1/Q2 2026 (which include manufacturers such as JinkoSolar, Trina, JA Solar, ZNShine Solar, and Phono Solar), which could complicate financing for commercial projects requiring Tier 1-level bankability. - **Efficiency trails segment leader** - Peak efficiency of 22.53% falls short of the Luxor Solar ECO LINE HJT Glass-Glass Bifacial series (22.74%) by about 0.21 percentage points, translating to a slightly lower power yield per m² at equal module area. ## About this series The Mysolar USA GOLD N-Type TOPCon Bifacial (Dual-glass Framed N132) series is designed for high energy production under real-world conditions, even when the installation doesn't have ideal sunlight. The use of **N-type cells in the TOPCon technology** helps minimize losses due to degradation and maintain stable performance for a long time, which is important for investments that span decades. The module is **bifacial**, meaning it can utilize reflected light from the ground, which is a significant advantage in ground-mounted installations, on bright roofs, and with modern mounting structures. The **glass-glass (dual-glass) construction** makes the panel more resistant to moisture, temperature changes, and heavy use, while the **framed version** simplifies installation in typical systems used in Poland. This series is particularly well-suited for PV farms, commercial installations, and projects where long-term predictability and resistance to harsh conditions are important. ## Notable figures - At 22.1% efficiency, this panel is on par with typical \*\*TOPCon 650-700W\*\* modules - 220.5 W/m² power density is 3.2 W/m² below \*\*TOPCon 650-700W\*\* median (223.7 W/m²) - requires larger installation area - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 650-700W\*\* panels - Weight of 38.5 kg is 3.9 kg above \*\*TOPCon 650-700W\*\* median (34.6 kg) - verify structural support - 85% bifaciality enables rear-side power generation, boosting yield by 4-13% on reflective surfaces ## Questions ### What is the maximum power output of the Mysolar USA GOLD N-Type TOPCon Bifacial N132 panel and how many cells does it have? The GOLD N-Type TOPCon Bifacial N132 series reaches a maximum power output of 700 Wp under STC conditions. The N132 designation refers to 132 N-type TOPCon cells per module. The combination of high wattage and bifacial design allows for greater energy yield per square foot compared to standard monofacial modules of a similar footprint. ### What is TOPCon technology and why does the GOLD N132 series degrade less than older PERC panels? TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell architecture featuring an ultra-thin silicon oxide interlayer that minimizes carrier recombination. In practice, this means lower Light Induced Degradation (LID) and an annual power loss of approximately 0.4%, well below typical PERC modules. Over a 25–30 year system lifetime, this translates into a measurably higher cumulative energy yield and a lower LCOE. ### What warranty does the Mysolar USA GOLD N-Type TOPCon Bifacial N132 come with and what does it cover? The manufacturer provides a 25-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. The extended power warranty is a premium-tier commitment for N-type modules, guaranteeing that the panel retains at least the manufacturer-specified percentage of its rated power after 30 years. This is a key factor in ROI calculations for utility-scale PV farms and commercial installations. ### When does it make sense to choose the bifacial Mysolar USA GOLD N132 over a standard monofacial panel? Bifacial modules deliver the highest energy gains in ground-mount installations with high-albedo surfaces (sand, concrete, white gravel), flat roofs with white TPO or PVC membranes, and single-axis tracker systems. Under those conditions the rear side captures reflected irradiance, boosting output by several percentage points over a monofacial equivalent. On dark pitched roofs the bifacial gain is minimal, though the dual-glass construction still enhances long-term durability. ### Does the framed dual-glass design of the GOLD N132 series work with standard racking systems? The framed dual-glass GOLD N132 is compatible with mainstream racking systems such as Renusol, K2, Schletter, and Esdec. The aluminum frame simplifies grounding and fits standard mid and end clamps without adapters. The glass back-sheet adds some weight compared to film-backed modules, so load-bearing capacity of the roof structure should be verified before a pitched-roof installation. ### Do the Mysolar USA GOLD N-Type TOPCon Bifacial N132 panels perform well in cold climates with frequent overcast conditions? N-type TOPCon cells feature a lower temperature coefficient of power than PERC cells, which limits losses on hot days and maintains good output in cold weather. The dual-glass construction provides robust protection against moisture ingress and freeze-thaw cycling. Under diffuse and overcast irradiance, N-type modules also retain a favorable current characteristic compared to older cell technologies, making them a solid choice for northern European climates. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/mysolar-gold-topcon-n132-framed-bifacial-module-680-700w-202-8ee898cab5c6.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +3.1 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | Cooler, lighter, +3.1 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | Cooler, lighter, +2.9 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | -40 W, lighter, +2.9 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Cooler, lighter, +2.9 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Cooler, lighter, +2.8 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | Cooler, lighter, +2.8 pp | | [Mysolar USA MS680N-DHBG](https://comparepv.com/panel/mysolar-usa-ms680n-dhbg) | 680 W | Very close match | | [Mysolar USA MS690N-DHBG](https://comparepv.com/panel/mysolar-usa-ms690n-dhbg) | 690 W | Very close match | | [Mysolar USA MS695N-DHBG](https://comparepv.com/panel/mysolar-usa-ms695n-dhbg) | 695 W | +10 W, +0.3 pp | | [Mysolar USA MS700N-DHBG](https://comparepv.com/panel/mysolar-usa-ms700n-dhbg) | 700 W | +15 W, +0.5 pp | | [Mysolar USA MS705N-HJTGB](https://comparepv.com/panel/mysolar-usa-ms705n-hjtgb) | 705 W | +20 W, cooler, +0.6 pp | | [Mysolar USA MS710N-HJTGB](https://comparepv.com/panel/mysolar-usa-ms710n-hjtgb) | 710 W | +25 W, cooler, +0.8 pp | | [Mysolar USA MS715N-HJTGB](https://comparepv.com/panel/mysolar-usa-ms715n-hjtgb) | 715 W | +30 W, cooler, +1.0 pp | | [Mysolar USA MS720N-HJTGB](https://comparepv.com/panel/mysolar-usa-ms720n-hjtgb) | 720 W | +35 W, cooler, +1.1 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +120 W, cooler, +3.1 pp | --- Source: https://comparepv.com/panel/mysolar-usa-ms685n-dhbg Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
