The panel uses **n-type TOPCon 4.0/5.0 cell technology**, combining high conversion efficiency with low power degradation over time, resulting in stable energy yield throughout the entire service life. Thanks to **bifacial power generation**, the module captures light reflected from the ground, increasing the overall energy yield of the installation without enlarging its footprint. A key advantage of the series is its **low Voc design**, which allows more modules to be connected in a single string, reducing wiring, mounting structure, and overall BoS costs, thereby lowering the system's LCOE. The design, based on 132 half-cut cells arranged in a 6x22 layout, provides better shading tolerance and lower resistive losses. The panel is backed by a **30-year linear power warranty** and a 15-year product warranty, and its low annual degradation (up to 0.4%) confirms the high durability of materials and manufacturing quality. This is a solution dedicated to commercial and utility-scale investors who expect maximum power density on limited roof or ground area. ## Notable figures - Efficiency of 23.0% matches the \*\*TOPCon 700-750W\*\* median - Power density of 230.2 W/m² matches the \*\*TOPCon 700-750W\*\* median - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 700-750W\*\* panels - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof - Ranked #1919 out of 14005 panels for efficiency in the database ## Questions ### What types of installations is the Astronergy CHSM66N(DG)/F-BH ASTRO N8 series designed for? This series is designed primarily for large ground-mounted installations, utility-scale power plants, agri-PV projects, and floating solar farms. Given its module format and bifacial technology, it performs best in utility-scale and commercial projects where maximizing power density on available land matters, rather than typical residential rooftop installations. ### What is n-type TOPCon technology and how does it differ from PERC? TOPCon (Tunnel Oxide Passivated Contact) is a newer-generation n-type cell technology offering higher energy conversion efficiency and lower power degradation over time compared to older p-type PERC cells. In practice, this means higher energy yield from the same panel area and more stable power output throughout the system's lifetime. ### How much extra energy does bifaciality provide in ASTRO N8 panels? Thanks to the double-glass bifacial design, the panel also captures light reflected off the ground beneath it, such as bright soil, gravel, or a reflective roof surface. The additional energy gain depends on the albedo of the surface and mounting height, typically ranging from a few to over ten percent more energy without increasing the installation footprint. ### What warranty comes with Astronergy ASTRO N8 modules? The panels come with a 30-year linear power warranty and a 15-year product warranty. Annual power degradation is limited to 0.4%, confirming the high durability of the TOPCon cells and the quality of materials used, which is important for long-term commercial and utility-scale projects. ### Why does low Voc voltage in this series matter to installers? Low Voc voltage allows more modules to be connected in a single string without exceeding inverter voltage limits. This reduces the number of strings, cable length, connectors, and combiner boxes required, lowering the cost of mounting structures and the overall balance of system (BoS), ultimately reducing the LCOE of the installation. ### What is the maximum power output and cell layout of this series? The module reaches a maximum power output of up to 735 Wp using 132 half-cut cells arranged in a 6x22 layout. Half-cut cell design reduces resistive losses and improves tolerance to partial shading, such as from clouds or debris, resulting in higher and more consistent energy production. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/710735ASTRO-N8_CHSM66NDGF-BH_2384x1303x33_EN_20260629-ac3cbcb05eb9.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | -35 W, lighter, +2.2 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | -40 W, lighter, +2.0 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Cooler, lighter, +2.0 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Cooler, lighter, +1.9 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | -45 W, lighter, +1.8 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | -45 W, lighter, +1.8 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | -45 W, lighter, +1.8 pp | | [Astronergy CHSM66N(DG)/F-BH-705](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm66n-dg-f-bh-705) | 705 W | -10 W, -0.3 pp | | [Astronergy CHSM66N(DG)/F-BH-710](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm66n-dg-f-bh-710) | 710 W | Very close match | | [Astronergy CHSM66N(DG)/F-BH-720](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm66n-dg-f-bh-720) | 720 W | Very close match | | [Astronergy CHSM66N(DG)/F-BH-725](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm66n-dg-f-bh-725) | 725 W | +10 W, +0.3 pp | | [Astronergy CHSM66N(DG)/F-BH-730](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm66n-dg-f-bh-730) | 730 W | +15 W, +0.5 pp | | [Astronergy CHSM66N(DG)/F-BH-735](https://comparepv.com/panel/astronergy-chsm66n-dg-f-bh-735) | 735 W | +20 W, +0.7 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +90 W, cooler, +2.1 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +85 W, cooler, +1.9 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +80 W, cooler, +1.8 pp | --- Source: https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm66n-dg-f-bh-715 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.
