The application of heterojunction cell architecture and a multi-string conduction structure translates to lower internal losses and better performance under partial shading - a key consideration for roofs with flashing, chimneys, or ventilation systems. The **bifacial** option harnesses reflected light from the ground, effectively boosting energy yield in ground-mounted and light-colored roof installations. A key feature of this series is also the **double glass** construction, which enhances material aging resistance and environmental resilience, enabling the modules to withstand moisture and temperature fluctuations effectively. Furthermore, the **low temperature coefficient** helps maintain efficiency during hot days, and **compatibility with 1500 V systems** facilitates the design of larger installations. This is a sensible choice for PV farms, C&I objects, and demanding investors seeking to minimize risk and operational costs. ## Notable figures - Efficiency of 20.6% matches the \*\*PERC 450-500W\*\* median - At 206.3 W/m² power density, roof space requirements are typical for \*\*PERC 450-500W\*\* panels - At -0.35%/°C, hot weather performance is typical for \*\*PERC 450-500W\*\* panels - Weight of 29.0 kg is 4.5 kg above \*\*PERC 450-500W\*\* median (24.5 kg) - verify structural support - 70% bifaciality enables rear-side power generation, boosting yield by 4-10% on reflective surfaces ## Questions ### What is the maximum power output of the ZNShine ZXM7-SHLDD132 panel? Panels in the ZXM7-SHLDD132 series reach a maximum power output of up to 510 Wp. This high yield comes from half-cut PERC cell architecture and a multi-busbar current-carrying design, which reduce internal losses. This makes them attractive for both utility-scale PV farms and large C&I rooftop installations where maximizing output per square meter matters. ### How does the bifacial variant of the ZXM7-SHLDD132 series differ from a standard panel? The bifacial variant is active on both sides of the module, allowing it to capture light reflected from the ground, roof, or surroundings. In practice this means additional energy yield, especially in ground-mounted systems on light-colored surfaces or bright rooftops. With proper mounting, such as east-west racking, the energy gain can be noticeably higher than with a standard one-sided module. ### What advantage does the double glass construction offer in ZNShine ZXM7-SHLDD132 panels? The double glass construction replaces the rear backsheet with a glass layer, significantly improving resistance to moisture, corrosion, and material aging over time. Panels better withstand temperature fluctuations and harsh weather conditions, resulting in longer, more stable system performance. This is especially valued in projects where low failure rates over many years of operation are a priority. ### What warranty comes with ZNShine ZXM7-SHLDD132 panels? The manufacturer provides a 12-year product warranty along with a 30-year power output warranty. This offers long-term protection against both material and manufacturing defects, as well as excessive power degradation over time. For investors in commercial installations and PV farms, this is a key factor when calculating project profitability over a 25-30 year horizon. ### Do ZNShine ZXM7-SHLDD132 panels perform well in hot climates? Yes, the series features a low temperature coefficient for power, meaning a smaller drop in efficiency during high module operating temperatures. In practice, the panels maintain their rated power better on hot, sunny days compared to modules with weaker thermal parameters. This is an important feature for ground-mounted systems and rooftops exposed to sunlight for most of the day. ### Are ZNShine ZXM7-SHLDD132 panels compatible with 1500 V inverter systems? Yes, modules in this series are designed to be compatible with 1500 V systems, making it easier to design longer strings and larger installations with fewer wiring and BoS components. This helps lower the cost per megawatt of installed capacity, which is significant for large-scale PV farms and C&I projects. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ZXM7-SHLDD132-182-2094-1134-30-32NH-485-510W-350mm-20220823-6846f818347e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +4.4 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +4.2 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +4.1 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +3.9 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +3.9 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | Cooler, lighter, +3.9 pp | | [ZNShine ZXM7-SHLDD132-485](https://comparepv.com/panel/znshine-zxm7-shldd132-485) | 485 W | -0.2 pp | | [ZNShine ZXM7-SHLDD132-495](https://comparepv.com/panel/znshine-zxm7-shldd132-495) | 495 W | +0.2 pp | | [ZNShine ZXM7-SHLDD132-500](https://comparepv.com/panel/znshine-zxm7-shldd132-500) | 500 W | +10 W, +0.4 pp | | [ZNShine ZXM7-SHLDD132-505](https://comparepv.com/panel/znshine-zxm7-shldd132-505) | 505 W | +15 W, +0.6 pp | | [Gamko New Energy GKA120N-PRO-590W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-590w) | 590 W | +100 W, cooler, +3.2 pp | | [Gamko New Energy GKA120N-PRO-585W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-585w) | 585 W | +95 W, cooler, +3.0 pp | | [Bisol BGO 580](https://comparepv.com/panel/bisol-bgo-580) | 580 W | +90 W, cooler, +2.9 pp | | [Gamko New Energy GKA120N-PRO-580W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-580w) | 580 W | +90 W, cooler, +2.8 pp | --- Source: https://comparepv.com/panel/znshine-zxm7-shldd132-490 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.
