These are **bifacial** modules in **double glass** construction, capable of harnessing reflected light from the ground surface, thereby enhancing annual production. The application of **half-cut technology** minimizes losses and supports stable operation under partial shading, while multi-string wiring facilitates a uniform energy flow and higher reliability. In practice, this series addresses typical challenges faced by large-scale projects and industrial roofs: reduced yield during weaker light conditions, increased risk of micro-cracking, and faster aging in harsher environments. These modules are engineered for operation in areas with elevated humidity, dust exposure, or near agricultural installations-hence, they perform exceptionally well in PV farms, warehouses, industrial facilities, and commercial projects where **external resistance** and predictable operation are crucial. ## Notable figures - At 21.4% efficiency, this panel is on par with typical \*\*PERC 600-650W\*\* modules - Power density of 213.8 W/m² matches the \*\*PERC 600-650W\*\* median - Temperature coefficient of -0.34%/°C matches the \*\*PERC 600-650W\*\* median - At 35.0 kg, weight matches the \*\*PERC 600-650W\*\* median - Bifacial design (70% factor) captures reflected light - adds 4-10% yield on ground-mount or white roof ## Questions ### How much extra energy do the bifacial ZNShine ZXM8-TPLDD120 panels actually generate? Thanks to the double glass construction and bifacial technology, ZXM8-TPLDD120 modules capture additional light reflected from the ground surface beneath the array. With a bright surface such as gravel or a white roof membrane, annual energy yield can increase by several to over ten percent compared to a monofacial module of the same 610 Wp rating. The actual gain depends on mounting height and ground albedo. ### Are ZXM8-TPLDD120 panels suitable for large industrial roofs and solar farms? Yes, this series is primarily designed for commercial and utility-scale installations. Dimensions of 2172x1303 mm and a weight of about 35 kg require a sturdy mounting structure, typical of industrial roofs and ground-mounted solar farms. Resistance to humidity and dust makes these modules well suited for use near agricultural and production facilities as well. ### What warranty does ZNShine offer on power output and product quality for the ZXM8-TPLDD120 series? The manufacturer provides a 12-year product warranty and a 30-year linear power warranty, guaranteeing at least 84.95 percent of initial output after 30 years of operation. This is a standard typical of Tier 1 manufacturers, confirming the maturity of the technology and the financial stability of ZNShine as a supplier. ### How does half-cut cell technology in the ZXM8-TPLDD120 differ from full-cell modules? Half-cut cells are split in half, reducing electrical resistance and power losses under partial shading, for example from a chimney or antenna. If one half of the panel is shaded, the other half continues operating efficiently, and the multi-busbar (12BB) design further improves current flow and reduces the risk of performance loss from microcracks. ### What is the efficiency and maximum power output of the ZNShine ZXM8-TPLDD120 series? This series delivers up to 610 Wp with module efficiency reaching around 21.5 percent, placing it among the top-performing monocrystalline PERC panels on the market. Combining PERC cells with bifacial technology and a double glass build allows for high power density per unit area, which matters when roof or ground space is limited. ### Do ZXM8-TPLDD120 panels perform well in cold climates and low temperatures? Yes, the temperature coefficient of power is -0.34 percent per degree Celsius, meaning smaller power losses as panel temperature rises compared to many lower-cost modules. In cooler climates, where cell temperatures less often exceed reference test conditions, these modules achieve relatively higher production efficiency than during hot summer days. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ZXM8-TPLDD120-210-2172-1303-35-30NH-585-610W-350mm-20220830-f94617133f8a.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +3.8 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +3.6 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +3.4 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, lighter, +3.4 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +3.2 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | Cooler, lighter, +3.2 pp | | [ZNShine ZXM8-TPLD120-585](https://comparepv.com/panel/znshine-zxm8-tpld120-585) | 585 W | -20 W, -0.7 pp | | [ZNShine ZXM8-TPLD120-590](https://comparepv.com/panel/znshine-zxm8-tpld120-590) | 590 W | -15 W, -0.5 pp | | [ZNShine ZXM8-TPLD120-595](https://comparepv.com/panel/znshine-zxm8-tpld120-595) | 595 W | -10 W, -0.4 pp | | [ZNShine ZXM8-TPLD120-600](https://comparepv.com/panel/znshine-zxm8-tpld120-600) | 600 W | Very close match | | [Gamko New Energy GKA210N120](https://comparepv.com/panel/gamko-new-energy-gka210n120) | 680 W | +75 W, lighter, +2.7 pp | | [Gamko New Energy GKA210N120-675](https://comparepv.com/panel/gamko-new-energy-gka210n120-675) | 675 W | +70 W, lighter, +2.5 pp | | [Q-SUN Solar QN-670HJT-01](https://comparepv.com/panel/q-sun-solar-qn-670hjt-01) | 670 W | +65 W, cooler, +2.3 pp | | [Gamko New Energy GKA210N120-670](https://comparepv.com/panel/gamko-new-energy-gka210n120-670) | 670 W | +65 W, lighter, +2.3 pp | | [Q-SUN Solar QN-665HJT-01](https://comparepv.com/panel/q-sun-solar-qn-665hjt-01) | 665 W | +60 W, cooler, +2.1 pp | | [Gamko New Energy GKA210N120-665](https://comparepv.com/panel/gamko-new-energy-gka210n120-665) | 665 W | +60 W, lighter, +2.1 pp | --- Source: https://comparepv.com/panel/znshine-zxm8-tpldd120-605 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.
