Thanks to **monocrystalline N-type cells in TOPCon technology**, the panels maintain their parameters over time and are less susceptible to typical operational losses, translating to more stable energy production year after year. The application of **double-sided power** allows utilizing reflected light from the ground - this advantage is particularly relevant for installations on light-colored roofs, carports, flat roofs, and ground-mounted structures. Another key feature is the **double glazing with anti-reflective coating**, which enhances resistance to atmospheric factors and facilitates maintaining high efficiency in challenging conditions. For installers, the **compatibility with 1500V systems** simplifies designing larger strings in commercial projects. This is the series for clients who wish to combine the aesthetics of modern modules with predictable yield and longevity clearly distinguishing them from standard single-sided panels. ## Notable figures - Efficiency of 22.3% matches the \*\*TOPCon 400-450W\*\* median - At 222.8 W/m² power density, roof space requirements are typical for \*\*TOPCon 400-450W\*\* panels - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 400-450W\*\* median - At 24.5 kg, this panel is 2.5 kg heavier than the \*\*TOPCon 400-450W\*\* median (22.0 kg) - more demanding for installation crews - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface ## Questions ### How does TOPCon technology in ZNShine ZXM7-UHLDD108 panels differ from standard PERC cells? TOPCon (Tunnel Oxide Passivated Contact) cells use N-type monocrystalline silicon with an additional passivation layer that reduces electron recombination. This results in higher efficiency (up to 22.5%), lower power degradation over time, and better performance at high temperatures compared to cheaper P-type PERC panels. For customers, this means higher energy yield from the same roof area over the panel's lifetime. ### How much extra energy do the bifacial glass-glass ZXM7-UHLDD108 modules actually generate? These panels use a glass-glass design, so the rear side also generates electricity from light reflected off the mounting surface. Depending on the albedo of the surroundings (light-colored roofing, gravel, white membrane), the additional energy gain can range from a few percent up to 25%. Flat roofs, carports, and ground-mounted installations with bright surroundings benefit the most. ### What warranty comes with ZNShine ZXM7-UHLDD108 panels, and how much power do they retain after 30 years? The manufacturer provides a 12-year product warranty and a 30-year linear power output warranty. After 30 years of operation, the panel is guaranteed to retain at least 87.4% of its original rated power. This is a standard benchmark for the latest generation of TOPCon panels and noticeably longer than typical PERC modules, which usually cap power warranties at 25 years. ### Are ZXM7-UHLDD108 panels compatible with 1500V inverter systems? Yes, the ZXM7-UHLDD108 series is designed for installations using a 1500V DC system voltage, which is the standard for large commercial and utility-scale solar farms. This allows for longer panel strings with fewer inverters and less wiring, reducing upfront costs and simplifying electrical design for larger projects. ### Can the double-glass construction of ZNShine panels withstand harsh weather and snow loads? Yes, the glass-glass modules with anti-reflective coating withstand front-side loads of up to 5400 Pa and rear-side loads of up to 2400 Pa, meeting standards suitable for regions with heavy snow and wind loads. The dual-glass structure also protects the cells against moisture ingress and microcracks better than a standard backsheet, extending the panel's lifespan in demanding climates. ### How much does the ZNShine ZXM7-UHLDD108-435 panel weigh, and does it require a reinforced roof structure? The 435Wp panel weighs approximately 24.5 kg with dimensions of 1722x1134x30 mm, due to the double-glass construction instead of a lightweight backsheet. This is a few kilograms heavier than standard one-sided panels, so on older or lighter roof structures it's worth having an installer verify the roof's load capacity before proceeding with the installation. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ZXM7-UHLDD108-182-1722-1134-30-28-415-435W-350mm-20230120-E-6010e674f9c3.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +50 W, lighter, +2.0 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +50 W, cooler, +2.0 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +50 W, cooler, +2.0 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +50 W, cooler, +2.0 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +50 W, cooler, +2.0 pp | | [ZNShine ZXM7-SH108-395W](https://comparepv.com/panel/znshine-zxm7-sh108-395w) | 395 W | Hotter, -2.1 pp, -5 yr warranty | | [ZNShine ZXM7-SH108-400W](https://comparepv.com/panel/znshine-zxm7-sh108-400w) | 400 W | Hotter, -1.8 pp, -5 yr warranty | | [ZNShine ZXM7-SH108-405W](https://comparepv.com/panel/znshine-zxm7-sh108-405w) | 405 W | Hotter, -1.5 pp, -5 yr warranty | | [ZNShine ZXM7-SH108-410W](https://comparepv.com/panel/znshine-zxm7-sh108-410w) | 410 W | Hotter, -1.3 pp, -5 yr warranty | | [ZNShine ZXM7-SH108-415W](https://comparepv.com/panel/znshine-zxm7-sh108-415w) | 415 W | Hotter, -1.0 pp, -5 yr warranty | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +75 W, cooler, +2.7 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +60 W, cooler, +2.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +70 W, cooler, +2.4 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +55 W, cooler, +2.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +65 W, cooler, +2.2 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +65 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/znshine-zxm7-uhldd108-435 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
