What distinguishes these modules from traditional solutions is, above all, the **use of a graphene coating** with unique hydrophilic and self-cleaning properties. Thanks to it, the panels handle organic contaminants and dust much better, which directly limits power drops and system maintenance costs. The **bifacial double glass** design guarantees not only higher energy production through the efficient use of light reflected from the ground, but also exceptional resistance to extreme weather phenomena and chemical degradation processes. This series was designed for investors looking for uncompromising quality for large-scale projects, ground-mounted farms, and industrial roofs. The use of **multi-busbar cell technology** effectively minimizes the risk of micro-cracks and optimizes current flow within the module. By choosing ZNShine ZXM8-TPLDD132, you gain the certainty of stable system operation for decades, even in demanding environments with high humidity or salinity, making these panels one of the most reliable products in their class. ## Notable figures - Efficiency of 21.6% matches the \*\*PERC 650-700W\*\* median - At 215.7 W/m² power density, this panel generates 3.2 W/m² more per unit area than \*\*PERC 650-700W\*\* median (212.5 W/m²) - Temperature coefficient of -0.34%/°C matches the \*\*PERC 650-700W\*\* median - Weight of 38.5 kg is 4.0 kg above \*\*PERC 650-700W\*\* median (34.5 kg) - verify structural support - Bifaciality factor of 70% can add 4-10% extra yield with reflective mounting surface ## Questions ### What is the warranty on ZNShine ZXM8-TPLDD132 solar panels? The manufacturer covers the ZXM8-TPLDD132 series with a 12-year product warranty and a 30-year linear power output warranty. This means that after three decades of operation the panel should still deliver a guaranteed percentage of its rated power. This level of coverage is typical for Tier 1 manufacturers and gives investors confidence in the long-term profitability of the installation. ### What is the graphene coating on ZNShine ZXM8-TPLDD132 panels, and does it really make a difference? The graphene coating is a layer with hydrophilic, self-cleaning properties applied to the front glass of the module. It causes rainwater to spread evenly and wash away dust and organic soiling instead of leaving streaks. In practice this results in smaller power losses between cleanings and lower maintenance costs, especially in utility-scale installations where manual panel washing is expensive. ### Is the bifacial double glass construction of the ZXM8-TPLDD132 suitable for ground-mounted solar farms? Yes, bifacial double glass panels in this series are a strong choice for ground-mounted farms. The rear side of the module captures light reflected off the ground surface, which over bright surfaces like white gravel or snow can boost energy yield by up to several percent compared with monofacial panels. The all-glass construction also improves resistance to moisture, corrosion, and chemical degradation in demanding field conditions. ### What is the maximum power output of panels in the ZXM8-TPLDD132 series? The highest-power variants in the ZXM8-TPLDD132 series reach up to 670 Wp. This reduces the number of modules needed to achieve a target system capacity, lowering the cost of mounting structures, cabling, and installation labor — particularly valuable for utility-scale projects and industrial rooftops. ### What does multi-busbar cell technology bring to these panels? Multi-busbar technology increases the number of electrical connections across the cell surface, shortening current flow paths and reducing mechanical stress at any single soldering point. The result is a lower risk of microcracks during transport and operation, plus more stable performance even under partial shading or damage to an individual cell. ### Is ZNShine a reliable manufacturer to rely on for a large-scale investment? ZNShine holds Tier 1 manufacturer status, indicating financial stability and a proven bankability track record for projects using its modules. The company is headquartered in China with many years of experience producing PV panels for global markets. Tier 1 status matters for bank financing of large installations, since lenders and insurers are more willing to back equipment from established, financially stable manufacturers. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ZXM8-TPLDD132-210-2384-1303-35-30NH-645-670W-350mm-20220926-5e04d0ce29d5.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +3.6 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | Cooler, lighter, +3.6 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | Cooler, lighter, +3.4 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +3.4 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Cooler, lighter, +3.4 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Cooler, lighter, +3.3 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | Cooler, lighter, +3.2 pp | | [ZNShine ZXM8-TP132-645W](https://comparepv.com/panel/znshine-zxm8-tp132-645w) | 645 W | Lighter, -0.8 pp, -5 yr warranty | | [ZNShine ZXM8-TP132-650W](https://comparepv.com/panel/znshine-zxm8-tp132-650w) | 650 W | Lighter, -0.6 pp, -5 yr warranty | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +135 W, cooler, +3.5 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +130 W, cooler, +3.3 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +125 W, cooler, +3.2 pp | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | +120 W, cooler, +3.0 pp | | [Trina Solar TSM-NEG21C.20Q-760](https://comparepv.com/panel/trina-solar-tsm-neg21c-20q-760) | 760 W | +90 W, cooler, +2.9 pp | | [AIKO AIKO-A785-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a785-grh78dw) | 785 W | +115 W, cooler, +2.8 pp | | [Gokin GK-4-78HGBD-780M](https://comparepv.com/panel/gokin-gk-4-78hgbd-780m) | 780 W | +110 W, cooler, +2.7 pp | --- Source: https://comparepv.com/panel/znshine-zxm8-tpldd132-670 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.
