In the summer, when the module temperature on the roof exceeds 60°C, this difference translates into a significantly higher daily energy yield. - **Efficiency up to 22.5% and power up to 580 W** - The performance range of 21.9–22.5% places the ASTRO N5 series in the top decile of the monofacial 182 mm segment available at its launch (2022). Comparable bifacial products from Emvee and ZNShine achieve a maximum of 22.44–22.45%, meaning that the ASTRO N5 does not lose efficiency even when compared to bifacial competitors. - **30-year linear warranty – 87.4% power** - The official datasheet (astronergy.com, April 2023) confirms that the module retains ≥87.40% of its nominal power after 30 years of operation. This is a more favorable threshold than the typical 25-year warranties offered for PERC modules, which guarantee approximately 84–85% performance, and it provides coverage for 5 additional years. - **Tier-1 BNEF – fully bankable** - Astronergy (Chint New Energy) has maintained its BNEF Tier 1 status consistently, including in Q1 2026 (56 GW of installed capacity). This means that for C&I and PV farm projects, financing is readily available without the need for additional technical due diligence to verify the manufacturer's credibility. - **SMBB architecture + half-cut (144 cells)** - The half-cut design reduces the working current in the cell halves, lowering resistive losses and improving performance under partial shading. The SMBB (Super Multi Busbar) technology reduces mechanical stress, which limits the risk of microcracks during transport and assembly – this is particularly important for modules with an area of approximately 2.58 m². ## Cons - **The product line has been discontinued.** - The ASTRO N5 CHSM72N-HC monofacial (182) series is designated as discontinued (introduced in 2022). This means that the availability of these modules on the secondary market is limited, there is a risk of not being able to find identical replacements in case of a single module failure, and there may be difficulties in fulfilling the 30-year warranty service in terms of power. - **Monofacial vs. Bifacial Equivalents** - All three bifacial modules (Emmvee Titanium Duo, Emmvee Titanium Clear, ZNShine ZXM7-UHLD144) have comparable efficiency rates of 22.44–22.45%. In utility-scale installations with a clear surface, bifacial modules typically generate 5–15% additional power from the rear side – an advantage that monofacial ASTRO N5 modules cannot provide. ## About this series The Astronergy ASTRO N5 / CHSM72N-HC Monofacial (182) series was designed for high energy yield from classic installations - without the need for bifacial modules. Key to this is the combination of **n-type TOPCon cells** and half-cut architecture, translating to more stable performance over time and reduced sensitivity to typical operational losses. In practice, this means greater output when rooftop or ground conditions aren't ideal, meeting investors' expectations for predictable results. Against the competition, the series stands out for its refined current collection thanks to the **SMBB construction**, improving performance under partial shading and minimizing risks of micro-cracking during transportation and installation. An additional advantage is its **low sensitivity to high temperatures**, which is crucial during summer months on roofs with limited ventilation. This is an excellent choice for C&I installations, PV farms, and larger rooftops, where **low LCOE and reduced BOS costs** matter, and investors seek cutting-edge technology without compromising on reliability. ## Notable figures - At 22.5% efficiency, this panel is on par with typical \*\*TOPCon 550-600W\*\* modules - At 224.5 W/m² power density, roof space requirements are typical for \*\*TOPCon 550-600W\*\* panels - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 550-600W\*\* panels - Weight of 26.9 kg (4.3 kg below \*\*TOPCon 550-600W\*\* median of 31.2 kg) allows easier transport and roof mounting - #4222 for efficiency, #2165 for temperature performance out of 14005 panels ## Questions ### Is the Astronergy ASTRO N5 CHSM72N-HC Monofacial series still available for purchase? The ASTRO N5 CHSM72N-HC Monofacial (182) series has been discontinued and is no longer actively offered by the manufacturer. Some residual stock may still exist with distributors; however, availability is severely limited. If you are planning a larger installation, it is advisable to consider currently manufactured Astronergy series featuring TOPCon technology, which deliver comparable or superior performance parameters. ### What warranty is provided for the Astronergy ASTRO N5 CHSM72N-HC Monofacial panels? The manufacturer offered a 12-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty. Astronergy's power warranty was backed by an independent insurance provider, which offered investors an additional layer of protection against potential financial difficulties on the manufacturer's part. ### What is TOPCon technology in the ASTRO N5 panels, and how does it differ from the older PERC technology? TOPCon (Tunnel Oxide Passivated Contact) is an n-type cell architecture featuring a passivating contact layer that minimizes charge carrier recombination. In practice, this translates to higher module efficiency, a lower temperature coefficient (approximately -0.29%/°C versus approximately -0.35%/°C for PERC), and slower long-term degradation. The CHSM72N-HC series built on TOPCon technology generates more energy throughout the day, especially during hot summer conditions when legacy PERC panels exhibit a pronounced power drop. ### What is the maximum power output of the Astronergy CHSM72N-HC panels, and are they suitable for large commercial installations? The top variant of the series achieves a peak power of 580 Wp under STC conditions. The large module format (182 mm cells, 72-cell half-cut layout) and high unit power output translate directly into lower BoS costs — installing fewer panels means fewer MC4 connectors, less cabling, and fewer mounting structures. This makes the CHSM72N-HC series a well-suited choice for utility-scale PV plants, industrial rooftops, and C&I installations where LCOE is the primary decision criterion. ### Why is the CHSM72N-HC series monofacial rather than bifacial, and when does that distinction matter? Monofacial modules harvest light from the front surface only, which simplifies the design and reduces the unit cost. Bifacial technology is most advantageous on high-albedo surfaces such as light-colored gravel ballast, snow, or bright concrete. On typical dark rooftops or grass-covered ground, the rear-side energy gain is minimal, making a monofacial module like the CHSM72N-HC the more economically optimal choice — one that also imposes no special mounting requirements regarding tilt angle or installation height. ### Do the Astronergy ASTRO N5 CHSM72N-HC panels perform well under partial shading or on overcast days? Yes. Thanks to the half-cut cell architecture and SMBB (Super Multi Busbar) construction, the series handles shading significantly better than older full-cell modules. Splitting each cell in half reduces resistive losses and limits the impact of shading on one string section from propagating through the rest of the array. The n-type TOPCon technology also provides superior low-irradiance response — performing well under diffuse light and overcast skies — which meaningfully increases real-world energy yield in a climate such as Poland's. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ASTRO-N5-565-585W-182-72-Monofacial-Module-8c2080dc0db0.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -20 W, cooler, +2.3 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -25 W, cooler, +2.1 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +50 W, heavier, +1.9 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | -30 W, lighter, +1.9 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | -40 W, lighter, +1.9 pp | | [Astronergy CHSM72M-HC-545](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm72m-hc-545) | 545 W | Hotter, -1.4 pp, -5 yr warranty | | [Astronergy CHSM72M-HC-550](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm72m-hc-550) | 550 W | Hotter, -1.2 pp, -5 yr warranty | | [Astronergy CHSM72M-HC-555](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm72m-hc-555) | 555 W | Hotter, -1.0 pp, -5 yr warranty | | [Astronergy CHSM72M-HC-560](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm72m-hc-560) | 560 W | Hotter, -0.8 pp, -5 yr warranty | | [Astronergy CHSM72N-HC-565](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm72n-hc-565) | 565 W | -15 W, -0.6 pp | | [Astronergy CHSM72N-HC-570](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm72n-hc-570) | 570 W | -10 W, -0.4 pp | | [Astronergy CHSM72N-HC-575](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm72n-hc-575) | 575 W | Very close match | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +70 W, cooler, +2.7 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +65 W, cooler, +2.5 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +60 W, cooler, +2.3 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +55 W, cooler, +2.1 pp | --- Source: https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm72n-hc-580 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
