This translates into higher and more stable energy yield in high-temperature conditions and over the module's long service life. - **Bifacial dual-glass construction** - The module captures light reflected from the ground (albedo), potentially boosting output by 8-15% over monofacial panels on high-albedo surfaces. The dual-glass build is also less susceptible to moisture ingress and laminate degradation than standard backsheet panels. - **30-year product and power warranty** - The manufacturer offers 30 years of coverage on both the product and power output - a premium-tier level exceeding the typical 25/25 or 25/30-year standard offered by most N-type module manufacturers. - **Frameless module design** - The absence of an aluminum frame reduces dirt and water buildup at the module edges and eliminates frame corrosion risk, making it easier to maintain high system efficiency over time. ## Cons - **Production discontinued (2020-2023)** - The series was manufactured from 2020 to 2023 and has since been discontinued. This means limited availability of warranty service, replacement parts, and matching modules for future repairs or claims. - **Manufacturer outside Tier-1 segment** - MY Solar is not included on Tier-1 bankable manufacturer lists, which can complicate securing bank financing or favorable insurance terms for larger projects - PV farms, carports, and commercial installations. - **Efficiency trails top-tier peers** - The series' maximum efficiency (22.1%) lags comparable N-type HJT/TOPCon modules at the same 480 W power class - Gamko's GKA96N-PRO reaches 24.02% and Sunket's SKT460~480M10-120D3 reaches 22.24%. This means lower yield per unit of roof or ground area. ## About this series The MY Solar PLATI N-type HJT Bifacial (Dual-glass, frameless) series is designed for maximum energy yield in environments where stability and real-world environmental resistance are crucial. The use of **N-type solar cells in HJT technology** ensures excellent module performance at high temperatures and high parameter repeatability over a long period - this is particularly important in installations aimed at predictable returns. A key advantage is the **bifacial design**, which allows for the utilization of reflected light from the ground, increasing production without expanding the surface area. The **dual-glass** module offers better resistance to moisture, temperature fluctuations, and mechanical loads compared to many standard panels with backsheets. Furthermore, the **frameless design** reduces the risk of dirt accumulation at the edges and facilitates maintenance, ensuring optimal efficiency. This solution is particularly suitable for PV farms, carports, and commercial installations, where yield, durability, and reduced downtime are important factors. ## Notable figures - Efficiency of 21.9% is 0.9pp below the \*\*HJT 450-500W\*\* median (22.8%) - At 220.4 W/m², this panel generates 7.3 W/m² less per unit area than \*\*HJT 450-500W\*\* median (227.7 W/m²) - -0.26%/°C temperature coefficient - 0.02pp worse than \*\*HJT 450-500W\*\* 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 - Ranked #6783 out of 14005 panels for efficiency in the database ## Questions ### Is the MY Solar PLATI N-type HJT Bifacial series still available for purchase? The MY Solar PLATI N-type HJT Bifacial (Dual-glass, frameless) series has been discontinued and is no longer offered as a new product. If you need modules with similar specs — HJT technology, bifacial design, and dual-glass construction — contact your distributor for a current alternative with comparable performance characteristics. ### How does HJT technology in the MY Solar PLATI series compare to standard PERC cells? HJT (Heterojunction Technology) cells combine a monocrystalline silicon wafer with thin amorphous silicon layers, resulting in a lower temperature coefficient than PERC cells. In practice, the PLATI series experiences less power loss on hot days, maintaining higher output during summer months compared to standard PERC modules with a similar nameplate power rating. ### What warranty does the MY Solar PLATI series carry? The MY Solar PLATI series comes with a 30-year product warranty and a 30-year power output warranty. This means the manufacturer covers both material and workmanship defects and guarantees a specified minimum power output for three decades — one of the longest combined warranty packages available in the residential and commercial PV module market. ### Does the MY Solar PLATI 480 Wp bifacial module actually generate more energy than a monofacial panel? Yes. The bifacial design allows the module to generate electricity from light reflected off the ground surface — soil, gravel, white roofing membranes, or snow. Real-world energy gain depends on the albedo of the surface and mounting height, but in typical ground-mount and carport installations it ranges from a few to over ten percent compared to an equivalent 480 Wp monofacial module. ### Why does the PLATI series use dual-glass frameless construction — does that complicate installation? Dual-glass construction (two glass layers instead of glass and a backsheet) improves resistance to moisture, UV exposure, and thermal cycling, extending module service life. The frameless design eliminates dirt and water accumulation at the edges, reducing shading losses over time. Installation requires clamps specifically rated for frameless modules, which is a standard solution for utility-scale and carport mounting systems. ### What types of installations are MY Solar PLATI N-type HJT Bifacial modules best suited for? The PLATI series is designed primarily for utility-scale PV farms, solar carports, and large commercial installations. HJT and bifacial technology deliver the greatest benefit where long-term yield predictability matters and where reflected irradiance can be captured. The frameless dual-glass construction also performs well in high-humidity or corrosive environments. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/mysolar-plati-hjt-frameless-144-module-460-480-2088x1032x5mm-3e892c50375e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +35 W, cooler, +3.1 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +20 W, lighter, +2.9 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +30 W, cooler, +2.8 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +15 W, lighter, +2.6 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +25 W, cooler, +2.6 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +25 W, lighter, +2.6 pp | | [MY Solar MS460NC-HJTPBFT](https://comparepv.com/panel/my-solar-ms460nc-hjtpbft) | 460 W | -15 W, -0.7 pp | | [MY Solar MS465NC-HJTPBFT](https://comparepv.com/panel/my-solar-ms465nc-hjtpbft) | 465 W | -10 W, -0.5 pp | | [MY Solar MS470NC-HJTPBFT](https://comparepv.com/panel/my-solar-ms470nc-hjtpbft) | 470 W | -0.3 pp | | [MY Solar MS480NC-HJTPBFT](https://comparepv.com/panel/my-solar-ms480nc-hjtpbft) | 480 W | +0.2 pp | | [Horay Solar HS530TC-MHG-D](https://comparepv.com/panel/horay-solar-hs530tc-mhg-d) | 530 W | +55 W, hotter, heavier | | [Horay Solar HS525TC-MHG-D](https://comparepv.com/panel/horay-solar-hs525tc-mhg-d) | 525 W | +50 W, hotter, heavier | | [Horay Solar HS520TC-MHG-D](https://comparepv.com/panel/horay-solar-hs520tc-mhg-d) | 520 W | +45 W, hotter, heavier | | [Horay Solar HS515TC-MHG-D](https://comparepv.com/panel/horay-solar-hs515tc-mhg-d) | 515 W | +40 W, hotter, heavier | --- Source: https://comparepv.com/panel/my-solar-ms475nc-hjtpbft Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
