Annual degradation of around 0.25% after the first year enables roughly 90-92% power retention after 30 years of operation. - **Low temperature coefficient** - A temperature coefficient of about -0.24%/°C (an advantage over TOPCon, typically around -0.30%/°C) translates into 4-6% higher energy yield during hot days, which matters for Polish rooftop installations in summer. - **Full 30/30-year warranty – matches segment leaders** - The manufacturer offers a 30-year product warranty and a 30-year linear power warranty, matching top-tier peer comparables such as Luxor Solar Eco Line HJT and exceeding the typical 25-year warranties of TOPCon modules (e.g. Trina Vertex N). - **High bifaciality** - The glass-glass HJT construction achieves a bifaciality factor of roughly 85-95%, which, depending on ground albedo and mounting height, can boost total array yield by an additional 5-25% compared to monofacial modules. - **Wide power range of 620-720 Wp** - 10 power variants from 620 to 720 Wp with efficiency up to 23.17% give installation designers flexibility to match module output to a specific roof area or PV farm without switching technology. ## Cons - **Production discontinued** - The series has been discontinued (launched in 2022, now marked as discontinued), meaning limited availability of warranty service and replacement parts, and potential difficulty sourcing identical modules for future array expansions. - **Manufacturer outside the Tier-1 bracket** - MY Solar is not listed among Tier-1 bankable manufacturers, unlike comparable series from DMEGC or Trina Solar. This can make it harder to secure bank financing or favorable insurance terms for larger commercial projects. - **Efficiency below top HJT competitors** - Maximum efficiency of 23.17% trails Luxor Solar Eco Line N-Type HJT (23.39%) and comparable DMEGC and Trina Vertex N modules (23.2%) at the same 720 Wp power class, yielding slightly less output per square meter. ## About this series The MY Solar GOLD N-Type HJT BIFACIAL series is a breakthrough solution combining heterojunction technology with N-type cells, which translates into unrivaled efficiency in real weather conditions. Thanks to the use of **advanced HJT technology**, these modules are characterized by minimal degradation and exceptional thermal stability, allowing for the generation of maximum energy even on hot summer days. A key advantage of this series is **full bifaciality**, which enables effective absorption of light reflected from the ground, significantly increasing the total yield from the installation compared to commonly used monofacial panels. This design effectively eliminates problems related to LID and LeTID effects, guaranteeing investors long-term security and a much faster return on investment. These panels are dedicated to the most demanding commercial projects and modern energy-efficient homes, where the priority is the highest yield from a limited mounting area. This solution stands out from the competition with its **extremely high bifaciality factor** and excellent sensitivity in low sunlight, which makes the system work efficiently from early dawn until late dusk. Choosing this series is a direct investment in **the highest energy efficiency**, which sets new standards for durability and reliability in the Polish renewable energy sector. ## Notable figures - Efficiency of 23.0% matches the \*\*HJT 700-750W\*\* median - At 230.2 W/m² power density, roof space requirements are typical for \*\*HJT 700-750W\*\* panels - -0.26%/°C temperature coefficient - 0.02pp worse than \*\*HJT 700-750W\*\* median (-0.24%/°C), expect higher hot weather losses - Bifacial design (95% factor) captures reflected light - adds 5-14% yield on ground-mount or white roof - In the top 14% for efficiency among all HJT panels ## Questions ### Is the MY Solar GOLD N-Type HJT BIFACIAL series still available for purchase? The MY Solar GOLD N-Type HJT BIFACIAL series has been discontinued and is no longer actively produced. If you require HJT or N-type bifacial technology with similar specifications, consider currently available series from MY Solar or alternative manufacturers. Contact your distributor to check whether any warehouse stock remains. ### What warranty does the MY Solar GOLD N-Type HJT BIFACIAL series come with? MY Solar provides a 30-year product warranty and a 30-year power output warranty for the GOLD N-Type HJT BIFACIAL series. This extended coverage is possible because of the inherently low degradation rate of HJT cells, which maintain high efficiency throughout the system's entire planned service life, directly supporting long-term return on investment. ### What is HJT technology and why do MY Solar GOLD panels perform better in hot weather? HJT (Heterojunction Technology) combines a thin amorphous silicon layer with a crystalline N-type substrate, resulting in a very low temperature coefficient. In practice, MY Solar GOLD modules lose significantly less power on hot summer days compared to standard PERC or monoSi panels. Higher summer output translates into a faster payback period for the system owner. ### What is the peak power output of the MY Solar GOLD N-Type HJT BIFACIAL panel and what does it mean for system design? The top variant in the MY Solar GOLD N-Type HJT BIFACIAL series reaches 720 Wp under STC conditions — among the highest power ratings on the market. This allows installers to achieve significant system capacity on a relatively small roof or ground-mount footprint, making it ideal for space-constrained commercial and residential projects. ### How much extra energy do the bifacial MY Solar GOLD panels generate compared to monofacial modules? The MY Solar GOLD N-Type HJT BIFACIAL series captures irradiance from both the front and rear surfaces of the module. Reflected light from high-albedo ground covers — white geomembrane, sand, or snow — can boost annual energy yield by several percentage points over monofacial panels. The bifacial gain is most pronounced in ground-mount systems and on light-colored rooftops. ### Are MY Solar GOLD HJT panels susceptible to LID and LeTID degradation that affects P-type modules? No. N-type HJT cells virtually eliminate Light-Induced Degradation (LID) and Light and Elevated Temperature Induced Degradation (LeTID) — phenomena that reduce output in P-type PERC modules during the first years of operation. MY Solar GOLD panels deliver their rated power from day one, shortening the system payback period and reducing long-term performance risk. ## 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-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | -35 W, lighter, +2.2 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | -40 W, lighter, +2.0 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | -15 W, lighter, +2.0 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | -20 W, lighter, +1.9 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | -45 W, lighter, +1.8 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | -45 W, lighter, +1.8 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | -45 W, lighter, +1.8 pp | | [MY Solar MS400N-HJTPB](https://comparepv.com/panel/my-solar-ms400n-hjtpb) | 400 W | -315 W, lighter, -10.1 pp | | [MY Solar MS405N-HJTPB](https://comparepv.com/panel/my-solar-ms405n-hjtpb) | 405 W | -310 W, lighter, -10.0 pp | | [MY Solar MS410N-HJTPB](https://comparepv.com/panel/my-solar-ms410n-hjtpb) | 410 W | -305 W, lighter, -9.8 pp | | [MY Solar MS415N-HJTPB](https://comparepv.com/panel/my-solar-ms415n-hjtpb) | 415 W | -300 W, lighter, -9.7 pp | | [MY Solar MS420N-HJTPB](https://comparepv.com/panel/my-solar-ms420n-hjtpb) | 420 W | -295 W, lighter, -9.5 pp | | [MY Solar MS680N-DHBG](https://comparepv.com/panel/my-solar-ms680n-dhbg) | 680 W | -35 W, hotter, -1.1 pp | | [MY Solar MS685N-DHBG](https://comparepv.com/panel/my-solar-ms685n-dhbg) | 685 W | -30 W, hotter, -1.0 pp | | [MY Solar MS690N-DHBG](https://comparepv.com/panel/my-solar-ms690n-dhbg) | 690 W | -25 W, hotter, -0.8 pp | | [MY Solar MS695N-DHBG](https://comparepv.com/panel/my-solar-ms695n-dhbg) | 695 W | -20 W, hotter, -0.6 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +90 W, heavier, +2.1 pp | --- Source: https://comparepv.com/panel/my-solar-ms715n-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.
