The use of **N-type HJT cells** ensures very good operational stability and reduces long-term power degradation, which translates into predictable production performance in investment models. The **bifacial** design allows for the recovery of additional energy from reflected light, enabling the modules to better utilize illuminated surfaces, snow, or roof membranes. The rigid, **frame structure** facilitates installation on standard mounting systems and increases resistance to construction site conditions. In practice, this is a good choice for PV farms, carports, and industrial roofs, where reliability, high productivity, and compatibility with typical infrastructure are important. Compared to many TOPCon solutions, it stands out due to its **high bifaciality** and emphasis on low degradation, which realistically improves the energy balance throughout the entire lifespan of the installation. ## Notable figures - Efficiency of 22.5% matches the \*\*HJT 700-750W\*\* median - At 225.3 W/m², this panel generates 4.9 W/m² less per unit area than \*\*HJT 700-750W\*\* median (230.2 W/m²) - At -0.26%/°C, loses 0.02pp more power per degree than \*\*HJT 700-750W\*\* median (-0.24%/°C) - Bifacial design (95% factor) captures reflected light - adds 5-14% yield on ground-mount or white roof - Ranked #3982 out of 14005 panels for efficiency in the database ## Questions ### How does HJT cell technology in the Mysolar USA GOLD 700–720W series differ from TOPCon panels? HJT cells combine a thin amorphous silicon layer with an N-type monocrystalline wafer, delivering a temperature coefficient of just -0.26%/°C — better than most TOPCon designs. The GOLD HJT 700–720W series also eliminates LID (light-induced degradation), so output stays stable from the very first season. In real-world terms, that translates to higher yield on hot summer days and more predictable energy production across the full 30-year warranty period. ### What warranty comes with the Mysolar USA GOLD N-Type HJT Bifacial 700–720W panels? The manufacturer provides a 30-year product warranty and a 30-year linear power warranty. HJT cells degrade at approximately 0.25–0.35% per year, meaning the modules retain over 87% of rated power after 30 years. This is one of the strongest warranty packages available in this power class and a critical input when modeling ROI for utility-scale PV projects. ### Are the Mysolar USA GOLD HJT 700–720W panels suitable for utility-scale solar farms or carports? Yes, the GOLD HJT 700–720W series is purpose-built for large-scale installations: utility-scale PV farms, solar carports, and industrial rooftops. The rigid aluminum-framed design is compatible with standard racking systems — no custom profiles required. At 720 W peak, fewer modules are needed per megawatt of installed capacity, reducing labor time and overall BoS costs. ### What does 95% bifaciality mean in the Mysolar USA GOLD HJT series and how much additional energy can I expect? A bifaciality factor of 95% means the rear side of the module generates up to 95% of the power produced by the front side under equal irradiance. With a reflective surface below — white roofing membrane, gravel, or snow — the rear side can contribute an additional 5–25% energy yield annually. This is among the highest bifaciality ratings available, significantly outperforming many TOPCon panels rated at 70–80%. ### What are the dimensions of the Mysolar USA GOLD HJT N132 panels and are they compatible with standard mounting systems? The GOLD HJT N132 modules measure 2384×1303×35 mm and are based on 132 G12 (210 mm) half-cut HJT cells. The rigid framed construction is fully compatible with standard aluminum racking used in PV farms and industrial rooftops — no custom hardware needed. Module weight is approximately 33–35 kg, which typically requires a two-person crew during installation. ### How do Mysolar USA GOLD HJT 700–720W panels perform in winter and on overcast days? HJT technology has the lowest temperature coefficient in its class (-0.26%/°C), delivering excellent cold-weather performance: at -20°C these modules produce noticeably more power than comparable PERC or TOPCon panels. The bifacial design also captures energy reflected off snow-covered ground. In diffuse light conditions, the heterojunction structure responds better to low-irradiance environments, improving total annual energy yield. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/mysolar-gold-hjt-bifacial-700-720w-210mm-202202-2384x1303x35-1232c77a0b13.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | -50 W, lighter, +2.7 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | -20 W, lighter, +2.7 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | -25 W, lighter, +2.5 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Lighter, +2.5 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Lighter, +2.4 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | -30 W, lighter, +2.3 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | -30 W, lighter, +2.3 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | -30 W, lighter, +2.3 pp | | [Mysolar USA MS680N-DHBG](https://comparepv.com/panel/mysolar-usa-ms680n-dhbg) | 680 W | -20 W, hotter, -0.6 pp | | [Mysolar USA MS685N-DHBG](https://comparepv.com/panel/mysolar-usa-ms685n-dhbg) | 685 W | -15 W, hotter, -0.5 pp | | [Mysolar USA MS690N-DHBG](https://comparepv.com/panel/mysolar-usa-ms690n-dhbg) | 690 W | -10 W, hotter, -0.3 pp | | [Mysolar USA MS695N-DHBG](https://comparepv.com/panel/mysolar-usa-ms695n-dhbg) | 695 W | Hotter | | [Mysolar USA MS705N-HJTGB](https://comparepv.com/panel/mysolar-usa-ms705n-hjtgb) | 705 W | Very close match | | [Mysolar USA MS710N-HJTGB](https://comparepv.com/panel/mysolar-usa-ms710n-hjtgb) | 710 W | +10 W, +0.3 pp | | [Mysolar USA MS715N-HJTGB](https://comparepv.com/panel/mysolar-usa-ms715n-hjtgb) | 715 W | +15 W, +0.5 pp | | [Mysolar USA MS720N-HJTGB](https://comparepv.com/panel/mysolar-usa-ms720n-hjtgb) | 720 W | +20 W, +0.6 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +105 W, heavier, +2.6 pp | --- Source: https://comparepv.com/panel/mysolar-usa-ms700n-hjtgb 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.
