At a cell temperature of 70°C, that difference translates to approximately 2.1% more power output relative to PERC. - **30-Year Linear Power Warranty with Low Degradation** - The manufacturer guarantees degradation of ≤1.0% in Year 1 and ≤0.4%/year in Years 2–30, retaining ~84.95% of nominal power after 30 years. While peers such as Huasun and JA Solar offer comparable warranty terms in this segment, the warranty being backed by a third-party insurer — as confirmed in the official datasheet — adds meaningful credibility to the claim. - **Zero-Busbar Technology with 20 Ribbons** - The zero-busbar (ZBB) design using 20 ribbons — versus 16 in standard SMBB configurations — shortens current paths and improves micro-crack resistance by 25% according to Astronergy's data. This directly translates to higher reliability under installation stresses and mechanical loading conditions such as snow and wind. - **Up to 85% Bifaciality and 23.8% Module Efficiency** - TOPCon 5.0 cells increase the bifaciality factor by more than 5 percentage points over TOPCon 4.0, reaching up to 85%. Module efficiency reaches 23.8% — closely competitive with peers such as the Huasun Everest G12R and JA Solar JAT60S41 LR (both at 23.9%), placing this series firmly among the top performers in the 54-cell segment. - **BNEF Tier 1 Status and KIWA TOP PERFORMER 2025 Certification** - Astronergy maintains BNEF Tier 1 bankable manufacturer status (56 GW of production capacity as of Q2 2025 data) and has received the independent KIWA TOP PERFORMER 2025 designation for the N7s 2.0 series. Both factors carry significant weight in project financing processes and investor quality due diligence. ## Cons - **Weight of 26.9 kg — Glass/Glass Construction** - The glass-glass build weighs 26.9 kg (module dimensions: 1961×1134×30 mm), which is substantially heavier than comparable glass-backsheet modules (typically 21–24 kg). For rooftops with limited load-bearing capacity or installations without contractor support, an additional structural assessment may be required. ## About this series The Astronergy ASTRO N7s 2.0 Bifacial (CHSM54RN(DG)/F-BH) series was designed for maximum yield from the same rooftop surface - without compromising on durability and aesthetics. These bifacial glass-glass modules feature **n-type TOPCon 5.0 cells**, which better withstand high operating temperatures and experience slower degradation over time, translating to more stable energy production year after year. A key highlight is the **ZBB (zero busbar) technology**, which minimizes shading on the cells and resistive losses while enhancing resistance to microcracking. In practical terms, this ensures reliable performance in real-world installation conditions and under mechanical stress. Compared to competitors, the series stands out thanks to the **Light Redirecting black film**, which optimizes light distribution and helps better utilize sunlight, and the **format facilitating transportation and installation** on roofs with limited space. This is a smart choice for residential and premium segments, where performance, appearance, and long-term reliability are key. ## Notable figures - 23.8% module efficiency - 1.1pp better than the \*\*TOPCon 500-550W\*\* median of 22.7% - Power density of 238.3 W/m² packs 10.9 W/m² more into the same footprint vs \*\*TOPCon 500-550W\*\* median (227.4 W/m²) - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 500-550W\*\* median - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces - Ranked #433 out of 14005 panels for efficiency in the database ## Questions ### What warranty does the Astronergy ASTRO N7s 2.0 Bifacial series carry and what does it cover? The ASTRO N7s 2.0 Bifacial series comes with a 25-year product warranty and a 30-year linear power output warranty. First-year degradation does not exceed 1%, and from year two through year thirty the annual degradation cap is 0.4% — meaning the module retains at least 87.4% of its nominal power after 30 years. The product warranty is backed by an international insurance underwriter, which significantly strengthens its credibility and enforceability. ### What is ZBB technology in the ASTRO N7s 2.0 panels and does it genuinely improve performance? ZBB (zero busbar) eliminates conventional busbars from the cell surface; current is collected through an alternative interconnection scheme that reduces shading of the active cell area and lowers resistive losses. Astronergy reports a module efficiency gain of 0.4–0.55% and an increase of more than 5% in rear-side power contribution compared to conventional busbar designs. An additional benefit is a more uniform stress distribution across the cell, which reduces the risk of microcracks. ### How do the ASTRO N7s 2.0 panels perform at high temperatures during summer? The power temperature coefficient is -0.29%/°C, which ranks among the best in its class. By comparison, older p-type modules typically exhibit coefficients of -0.35 to -0.45%/°C. In practical terms, this translates to lower losses on hot days — at a module surface temperature of 70°C, the ASTRO N7s 2.0 loses approximately 13% of its rated power, versus the typical 17–20% loss seen with BSF or PERC technology. ### Are the Astronergy ASTRO N7s 2.0 panels suitable for a pitched roof with limited space? Yes. Modules in the CHSM54RN(DG)/F-BH series measure 1961×1134×30 mm and weigh approximately 26.9 kg, which falls within the standard envelope for rooftop installations. This form factor was designed with ease of transport and installation on space-constrained roofs in mind. The glass-glass bifacial construction also provides superior mechanical resistance under wind and snow loads. ### Does the bifacial design of the ASTRO N7s 2.0 make sense for a typical residential rooftop installation? Yes, although the gain depends on the surface beneath the modules. Light-colored surfaces — white roofing membrane, light-colored tiles, gravel — reflect more irradiance onto the rear side of the panel and can increase energy yield by 5–15% compared to a monofacial module. Even on darker roofs, the glass-glass rear pane extends service life and improves moisture resistance, which justifies selecting this series in the premium segment. ### Is Astronergy a reliable panel manufacturer and can I count on warranty claims being honored 20 years from now? Astronergy (Chint New Energy) is listed on the Bloomberg NEF Tier 1 ranking and holds certifications from TÜV Rheinland, CE, ISO 9001/14001/45001, as well as the KIWA TOP PERFORMER 2025 distinction. The product warranty is underwritten by an independent international insurer — meaning that even if issues arise with the manufacturer, claims can be filed directly with the insurer. This represents a significant advantage over warranties that depend solely on the financial standing of the manufacturing company. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/510530astro-n7s-2-0-chsm54rndgf-bh-1961-1134-30-en-20250902-f78d37174cb9.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +1.2 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | -35 W, lighter, +1.0 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +30 W, cooler, +1.0 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +0.9 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +25 W, cooler, +0.8 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | -40 W, lighter, +0.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +0.7 pp | | [Astronergy CHSM54RN(DG)/F-BH-510](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm54rn-dg-f-bh-510) | 510 W | -20 W, -0.9 pp | | [Astronergy CHSM54RN(DG)/F-BH-515](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm54rn-dg-f-bh-515) | 515 W | -15 W, -0.6 pp | | [Astronergy CHSM54RN(DG)/F-BH-520](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm54rn-dg-f-bh-520) | 520 W | -10 W, -0.4 pp | | [Astronergy CHSM54RN(DG)/F-BH-525](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm54rn-dg-f-bh-525) | 525 W | Very close match | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, lighter, +0.6 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | Cooler, lighter, +0.6 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | Cooler, lighter, +0.6 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | +15 W, cooler, +0.5 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | Cooler, lighter, +0.4 pp | --- Source: https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm54rn-dg-f-bh-530 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.
