In practice, this means better tolerance to partial shading and lower internal losses, particularly noticeable on rooftops with obstructions (chimneys, dormers, skylights) and in installations where maximum surface utilization is key. A key feature of this series is also the **optional Full Black finish**, which facilitates aesthetic matching with modern roofs and facades without compromising on the robustness of the structure. The modules are prepared for operation in installations with **high system voltage (1500 V)**, supporting commercial and utility-scale projects through greater flexibility in string selection. Additionally, anti-reflective glass and an **IP68 junction box** are used, enhancing reliability in challenging weather conditions in Poland. This series will perform well on large industrial rooftops and in investment projects where yield, consistency, and predictable performance are crucial. ## Notable figures - Efficiency of 20.7% is 0.6pp below the \*\*PERC 550-600W\*\* median (21.3%) - Power density of 206.7 W/m² is 6.2 W/m² below \*\*PERC 550-600W\*\* median (212.9 W/m²) - needs more roof space - At -0.34%/°C, hot weather performance is typical for \*\*PERC 550-600W\*\* panels - Weight of 35.0 kg is 4.2 kg above \*\*PERC 550-600W\*\* median (30.8 kg) - verify structural support - Ranked #10990 out of 14005 panels for efficiency in the database ## Questions ### Are ZNShine ZXM8-TPLD120 solar panels still available for purchase? The ZXM8-TPLD120 series has been discontinued by ZNShine Solar and is no longer in active production. Availability is now limited to remaining distributor stock, so it's worth checking current inventory with your supplier before planning a large installation, since matching batch numbers for future system expansion may not be possible. ### What is the maximum power output of the ZXM8-TPLD120 series? Modules in the ZXM8-TPLD120 series reach a maximum power output of up to 610 Wp. That's a high figure for a monocrystalline PERC half-cut panel, meaning fewer modules are needed to reach a target system capacity, which lowers costs for mounting structures and cabling. ### What warranty comes with ZNShine ZXM8-TPLD120 panels? The manufacturer provides a 12-year product warranty and a 30-year power output warranty. This means that even after three decades of use, the panel should retain the guaranteed percentage of its original output, a standard offering from established tier 1 manufacturers with long-term service support. ### How does the ZXM8-TPLD120 series differ from bifacial modules? The ZXM8-TPLD120 is a monofacial module, generating power only from its front side. Unlike bifacial panels, it doesn't capture reflected light from the ground or roof surface, making it well suited for sloped and flat roofs with dark surfaces, where the albedo effect would be minimal anyway. ### Are ZNShine ZXM8-TPLD120 panels suitable for high system voltage installations? Yes, the modules are rated for system voltages up to 1500 V, which matters for large commercial and utility-scale solar farms. Higher system voltage allows for longer strings, reducing the number of inverters, DC cabling, and conductor losses, which lowers overall cost per kilowatt installed. ### Does the Full Black version of the ZXM8-TPLD120 series have lower efficiency than the standard version? The Full Black finish is an aesthetic option designed for modern roofs and facades and doesn't significantly reduce module power compared to the standard version. The difference is mainly visual (black frame and backsheet), not electrical, though in extreme heat the darker surface may cause slightly higher panel temperatures. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/zxm8-tpld120-210-2172-1303-35-30nh-585-610w-350mm-20230105-e-f876b5cc7977.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +4.1 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +3.9 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | Cooler, lighter, +3.9 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +45 W, cooler, +3.7 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, 19 kg lighter, +3.7 pp | | [ZNShine ZXM8-TPLD120-590](https://comparepv.com/panel/znshine-zxm8-tpld120-590) | 590 W | Very close match | | [ZNShine ZXM8-TPLD120-595](https://comparepv.com/panel/znshine-zxm8-tpld120-595) | 595 W | +10 W, +0.3 pp | | [ZNShine ZXM8-TPLD120-600](https://comparepv.com/panel/znshine-zxm8-tpld120-600) | 600 W | +15 W, +0.5 pp | | [ZNShine ZXM8-TPLD120-605](https://comparepv.com/panel/znshine-zxm8-tpld120-605) | 605 W | +20 W, +0.7 pp | | [Gamko New Energy GKA210N120](https://comparepv.com/panel/gamko-new-energy-gka210n120) | 680 W | +95 W, lighter, +3.4 pp | | [Gamko New Energy GKA210N120-675](https://comparepv.com/panel/gamko-new-energy-gka210n120-675) | 675 W | +90 W, lighter, +3.2 pp | | [Q-SUN Solar QN-670HJT-01](https://comparepv.com/panel/q-sun-solar-qn-670hjt-01) | 670 W | +85 W, cooler, +3.0 pp | | [Gamko New Energy GKA210N120-670](https://comparepv.com/panel/gamko-new-energy-gka210n120-670) | 670 W | +85 W, lighter, +3.0 pp | | [Q-SUN Solar QN-665HJT-01](https://comparepv.com/panel/q-sun-solar-qn-665hjt-01) | 665 W | +80 W, cooler, +2.8 pp | | [Gamko New Energy GKA210N120-665](https://comparepv.com/panel/gamko-new-energy-gka210n120-665) | 665 W | +80 W, lighter, +2.8 pp | | [Sunpro Power SPDG660-N120M12](https://comparepv.com/panel/sunpro-spdg660-n120m12) | 660 W | +75 W, cooler, +2.6 pp | --- Source: https://comparepv.com/panel/znshine-zxm8-tpld120-585 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
