The modules utilize an N-type architecture based on TOPCon technology and a half-cut structure, which translates into better performance under partial shading and lower connection losses. The multi-busbar structure improves current collection from the cells, and **double glass (glass-glass)** enhances resistance to moisture, microcracks, and challenging operating conditions. An additional advantage is **bifaciality** - the module can also operate from the rear side, enabling energy gains in areas with reflected light (light-colored roofs, gravel, concrete). In practice, this solution is ideal for PV farms, larger commercial roofs, and projects where high durability, better performance in low light, and predictable energy production over the long term are priorities. ## Notable figures - At 21.6% efficiency, this panel is on par with typical \*\*PERC 650-700W\*\* modules - Power density of 215.7 W/m² packs 3.2 W/m² more into the same footprint vs \*\*PERC 650-700W\*\* median (212.5 W/m²) - At -0.34%/°C, hot weather performance is typical for \*\*PERC 650-700W\*\* panels - At 33.5 kg, weight matches the \*\*PERC 650-700W\*\* median - #7734 for efficiency, #8778 for temperature performance out of 14005 panels ## Questions ### What is the maximum power output of the ZNShine ZXM8-TP132 panel and what installations is it suited for? The ZXM8-TP132 series reaches up to 670 Wp with efficiency above 21%. With 132 half-cut cells and a multi-busbar design, it works well for large commercial and industrial rooftop installations as well as utility-scale PV farms where maximizing energy yield per square meter matters most. ### What warranty comes with the ZNShine ZXM8-TP132 Series? The manufacturer provides a 12-year product warranty and a 25-year linear power warranty, standard for premium-grade PERC modules today. Annual power degradation is around 0.55%, so the panel retains a high performance level close to the guaranteed output even after 25 years of operation. ### Is the ZNShine ZXM8-TP132 bifacial and can it generate power from the rear side? No, the ZXM8-TP132 series is a mono-facial module, optimized for standard rooftop mounting facing one direction toward the sun. If you want extra energy gain from reflected light, consider the bifacial variant from the same product family - the ZXM8-TPLDD132 with double glass. ### What is PERC technology and what advantages does it bring to the ZXM8-TP132 panels? PERC (Passivated Emitter and Rear Contact) is a cell technology that adds a reflective passivation layer on the rear side, bouncing unused light back into the cell to increase absorption. In practice this means higher module efficiency, better performance under low-light conditions, and a lower temperature coefficient compared to older silicon cell technologies. ### Is ZNShine a reliable solar panel manufacturer? Yes, ZNShine is a China-based manufacturer with Tier 1 status, indicating financial stability, in-house production lines, and a long-standing presence on the global market. The modules meet IEC 61215, IEC 61730, and IEC 61701 standards, and Tier 1 status also makes it easier to secure bank financing for installations. ### How do the half-cut cells in the ZXM8-TP132 differ from traditional full-size cells? Half-cut cells are standard silicon cells cut in half, reducing resistive losses across busbar connections and improving module behavior under partial shading, such as from a chimney or neighboring building. In practice, a half-cut panel delivers higher energy yield and is less prone to output drops when sunlight exposure is uneven throughout the day. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/zxm8-tp132-210-2384-1303-35-30nh-645-670w-350mm-20220830-e-c7b342f3f533.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, +3.6 pp, +5 yr warranty | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | Cooler, +3.4 pp, +5 yr warranty | | [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, +3.4 pp, +5 yr warranty | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Cooler, +3.3 pp, +5 yr warranty | | [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 | -25 W, -0.8 pp | | [ZNShine ZXM8-TP132-650W](https://comparepv.com/panel/znshine-zxm8-tp132-650w) | 650 W | -20 W, -0.6 pp | | [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-tp132-670w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
