Subsequent years: 0.4% per year (linear degradation). This translates to approximately 150-200 kWh more per year for a 10 kWp installation, compared to typical PERC modules. - **Favorable temperature coefficient** - The efficiency of -0.29%/°C (data from the CHSM54N-HC datasheet) is significantly better than the standard PERC (-0.35%/°C). At a typical operating temperature of 60°C, this translates to approximately 7W more power per module compared to a comparable PERC module – which is particularly important in the Polish climate, where roofs can get very hot in the summer. - **30-year linear warranty + insurance** - The manufacturer guarantees >87.4% power output after 30 years, and the warranty is protected by an external insurance company (Lloyd's of London / Astronergy reinsurance program), which means that claims can be pursued even in the event of the manufacturer's bankruptcy – a rare feature in the mid-range segment. - **Bankability Tier 1 – BNEF's ranking of the top 6 globally** - Astronergy is listed on the BNEF Tier 1 list (confirmed for Q2 2025) and ranked 6th in the Bloomberg Bankability ranking in 2023, with an annual production capacity of 56 GW. For projects requiring bank financing, it is one of the few Tier B manufacturers with full market acceptance. - **Efficiency of 21.5–22.5% in a compact format** - The 54-cell format (1722×1134 mm) with efficiency up to 22.5% achieves a power density of approximately 227 W/m² – comparable to KDM Kingdom Solar (22.5%) and Lina Energy LEPV 132 (22.37%) in the same 440 Wp power range, while maintaining convenient installation logistics on rooftops. ## Cons - **Product warranty is only 15 years.** - The standard product warranty is 15 years, while some competitors in the TOPCon segment (including certain Astronergy and Luxor Solar variants on premium markets) offer 25 years. For prosumer installations with an expected lifespan of 25+ years, this difference is significant in the event of any mechanical issues. - **Performance below segment leader** - The maximum efficiency of 22.5% is lower than Luxor ECO LINE N-TYPE NON-REFLECT (22.86%) with the same power rating of 440 Wp and similar TOPCon technology. The difference of 0.36% in efficiency per panel with an area of approximately 1.95 m² translates to roughly 7 W per module – which, with 20 panels, results in approximately 140 Wp less without compromising on price. ## About this series The Astronergy ASTRO N5s (Monofacial Series) was designed for maximum energy production from limited roof space, without compromising on aesthetics and durability. These modules feature a compact structure, often chosen where convenient installation and a cohesive system appearance matter - such as on single-family homes, segment roofs, small businesses, or premium projects. A key advantage is the use of **n-type TOPCon cells**, which help maintain high efficiency over a long operational lifespan and reduce typical losses seen in standard technologies. In practice, this translates to a more reliable yield in real-world conditions, even at higher temperatures and varying sunlight exposure. Additionally, **SMBB technology** enhances current flow and improves resistance to micro-cracking, contributing to dependability. The ASTRO N5s features an **all-black design**, making it an excellent fit for modern roofs, where appearance is key. This series is for investors seeking **higher power density on the roof**, easier logistics, and a sensible cost-yield balance for years to come. ## Notable figures - Efficiency of 22.5% matches the \*\*TOPCon 400-450W\*\* median - At 225.3 W/m² power density, this panel generates 5.1 W/m² more per unit area than \*\*TOPCon 400-450W\*\* median (220.2 W/m²) - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 400-450W\*\* median - #4222 for efficiency, #2165 for temperature performance out of 14005 panels ## Questions ### What warranty coverage applies to Astronergy ASTRO N5s panels? The ASTRO N5s series comes with a 15-year product warranty covering manufacturing defects and material failures, along with a 30-year linear power output warranty. Under this warranty, Astronergy guarantees that the modules will retain at least 87.4% of their original rated power after three decades of operation. This represents one of the longest power warranty standards available on the market and reflects Astronergy's confidence in the long-term durability of its n-type TOPCon technology. ### What is TOPCon technology and why does it matter in the ASTRO N5s series? TOPCon (Tunnel Oxide Passivated Contact) is an n-type cell technology in which an ultra-thin silicon oxide interlayer suppresses charge carrier recombination at the contact interface. In practice, this translates into higher module efficiency (above 22%), a low temperature coefficient of approximately -0.29%/°C, and slower long-term degradation compared to mainstream p-type PERC cells. For a residential rooftop installation, this means more energy harvested from the same surface area over the system's lifetime. ### Are Astronergy ASTRO N5s panels suitable for a small residential rooftop? Yes, the ASTRO N5s series is specifically designed with prosumer and residential installations in mind. Modules rated up to 440 Wp feature compact dimensions of approximately 1722 × 1134 mm, making them well-suited for standard gabled and pitched roofs. The high power density allows more energy to be generated from a limited roof area, while the all-black design gives the installation a uniform, aesthetically consistent appearance on modern facades and dark roofing materials. ### Does the ASTRO N5s series generate power on overcast days or during high summer temperatures? Yes, although every panel experiences some efficiency loss under heat, the ASTRO N5s performs better than older p-type technologies in both scenarios. The low temperature coefficient of approximately -0.29%/°C means reduced power losses when module temperature rises above 25°C during summer. In addition, n-type TOPCon technology offers superior response to diffuse irradiance, resulting in a more stable energy yield under the variable solar conditions characteristic of the Polish climate. ### What does the all-black design of the ASTRO N5s mean, and does it affect performance? All-black refers to the configuration in which both the aluminum frame and the backsheet are finished in black, and the cells carry no visible white gaps between them. Aesthetically, the modules blend seamlessly into dark roofs, making them a popular choice for premium residential projects and semi-detached housing segments. The impact on electrical performance is minimal and practically imperceptible under real operating conditions, as the N5s series maintains a module efficiency above 22% regardless of the color variant selected. ### Is Astronergy a reliable manufacturer, and is the ASTRO N5s series available in Poland? Astronergy, part of the CHINT Group, is listed on Bloomberg's Tier 1 module manufacturer ranking, confirming both financial stability and consistent production quality. The company has earned the Top Performer designation in PVEL reliability testing on multiple occasions. ASTRO N5s panels are actively distributed in Poland through photovoltaic wholesale networks. The series remains in active production, so module availability and warranty service should not be concerns for purchases made in 2025. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/426222820661dc5a68df01-8584553d75e9.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +50 W, cooler, +2.0 pp | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +50 W, cooler, +2.0 pp | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +45 W, cooler, +1.8 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +45 W, cooler, +1.8 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +45 W, cooler, +1.8 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +45 W, cooler, +1.8 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +45 W, cooler, +1.8 pp | | [Astronergy CHSM54N(BL)-HC / CHSM54N(BLH)-HC (420W class)](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm54n-bl-hc-chsm54n-blh-hc-420w-class) | 420 W | -20 W, -1.0 pp | | [Astronergy CHSM54N(BL)-HC / CHSM54N(BLH)-HC (425W class)](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm54n-bl-hc-chsm54n-blh-hc-425w-class) | 425 W | -15 W, -0.7 pp | | [Astronergy CHSM54N(BL)-HC / CHSM54N(BLH)-HC (430W class)](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm54n-bl-hc-chsm54n-blh-hc-430w-class) | 430 W | -10 W, -0.5 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +70 W, cooler, +2.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +55 W, cooler, +2.3 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +65 W, cooler, +2.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +60 W, cooler, +2.0 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +60 W, cooler, +2.0 pp | --- Source: https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm54n-bl-hc-440w 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.
