This translates to meaningfully higher energy yield per m² of roof area without the need to increase the number of modules. - **25-Year Product Warranty** - The manufacturer provides a 25-year product warranty and a 30-year power output warranty (≥87.4% Pmax after 30 years), with degradation ≤0.4% per year from year 2 onward. By comparison, the peer-comparable DAH Solar DHN-54R18/DG offers only a 15-year product warranty — a significant difference from an investment protection standpoint. - **Low Temperature Coefficient of -0.29%/°C** - The Pmax temperature coefficient of -0.29%/°C (N-type TOPCon) is more favorable than that of typical PERC modules (-0.34 to -0.36%/°C). Under Polish summer conditions, with a module temperature of 65°C (Δ40°C above STC), power loss is approximately 11.6% versus 13.6–14.4% for PERC — a real difference in annual energy production. - **Bifacial Double Glass with SMBB Technology** - The glass-glass construction (1.6+1.6 mm tempered glass) provides hermetic protection against moisture and UV degradation, while the bifacial design enables additional yield from reflected irradiance. The SMBB busbars reduce the risk of micro-cracks in the cells and optimize current flow compared to standard multi-busbar solutions. - **BNEF Tier 1 Manufacturer, Top 6 Globally** - Astronergy (Chint) holds bankable status according to BloombergNEF and ranked in the top 6 module manufacturers worldwide by production capacity in 2023 (56,000 MW/year). This translates to strong project financing accessibility and reliable long-term serviceability. ## Cons - **Series Discontinued (2025)** - The CHSM54RNs(DG)/F-BH series was discontinued in 2025 and superseded by the ASTRO N7s 2.0 with TOPCon 5.0 technology. Limited market availability, the inability to expand an existing installation with identical modules in the future, and potentially restricted access to replacement parts represent real risks for systems that may require scaling. - **Weight of 21.5 kg — Roof Structural Assessment Required** - The double glass construction (1.6+1.6 mm) results in a module weight of 21.5 kg, typically 8–12% heavier than equivalent glass-backsheet modules (~19–20 kg). For larger rooftop installations (e.g., 20+ modules), a structural assessment of the roof load capacity is required, along with selection of mounting hardware certified for this weight class. ## About this series The Astronergy ASTRO N7s CHSM54RNs(DG)/F-BH series is an advanced solution based on n-type TOPCon cells that redefines the concept of efficiency in rooftop installations. Thanks to the use of **bifacial technology** and double-glass construction, these modules generate additional energy from reflected radiation while exhibiting the highest resistance to corrosive factors. A key distinguishing feature is the use of innovative rectangular cells, which allows for record power density while maintaining compact dimensions. This solves the problem of limited mounting space, enabling investors to achieve higher yields from every square meter of the roof. **An exceptionally low temperature coefficient** guarantees stable system operation even in full sun, which directly translates into a faster return on investment. This series is dedicated to demanding residential users and commercial facilities where reliability and aesthetics matter. **The use of SMBB busbars** effectively reduces the risk of micro-cracks and optimizes electron flow, providing a clear advantage over traditional competitor panels. By choosing these modules, you gain **increased fire safety** and a guarantee of longevity provided by the hermetic double-glass casing, perfectly adapted to the variable climatic conditions in Poland. ## Notable figures - Efficiency of 23.0% matches the \*\*TOPCon 450-500W\*\* median - 230.2 W/m² power density - 5.0 W/m² more than \*\*TOPCon 450-500W\*\* median (225.2 W/m²), more power per roof area - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 450-500W\*\* panels - Weight of 21.5 kg (2.5 kg below \*\*TOPCon 450-500W\*\* median of 24.0 kg) allows easier transport and roof mounting - #1919 for efficiency, #2165 for temperature performance out of 14005 panels ## Questions ### Is the Astronergy ASTRO N7s CHSM54RNs(DG)/F-BH series still available for purchase? The ASTRO N7s CHSM54RNs(DG)/F-BH series has been discontinued and is no longer actively offered by distributors. Isolated units may still exist in warehouse stock; however, availability is extremely limited. If you are looking for n-type TOPCon bifacial modules with comparable specifications, it is worth considering newer Astronergy series such as the ASTRO N7s 2.0, which deliver even higher efficiency and are covered by full warranty support. ### What warranty is provided for the Astronergy ASTRO N7s CHSM54RNs(DG)/F-BH panels? The manufacturer provides a 25-year product workmanship warranty on the module and a 30-year linear power output warranty, under which the panel retains at least 87.4% of its nominal power. The Astronergy warranty is additionally insured by an independent international insurer, providing financial protection even in the event of potential manufacturer insolvency. ### How much additional energy does the bifacial Astronergy ASTRO N7s panel generate from its rear side? Bifacial technology allows the rear side of the module to harvest irradiance reflected from the ground or rooftop surface. In typical rooftop installations with a light-colored surface or ground-mounted systems with an albedo of approximately 0.25, the bifacial gain is generally 5–15% per year relative to a monofacial panel. The actual yield gain depends on the mounting tilt angle, surface color, and local solar irradiation conditions, and should therefore be factored into the system design. ### Are the Astronergy ASTRO N7s CHSM54RNs(DG)/F-BH panels suitable for pitched-roof installations in the Polish climate? Yes, modules measuring 1762 × 1134 × 30 mm with a weight of 21.5 kg perform well on typical pitched roofs in Poland. The double-glass construction using 1.6+1.6 mm tempered glass provides mechanical resistance of up to 5400 Pa on the front face, reliably handling the snow loads characteristic of Polish winters. The n-type TOPCon technology ensures low temperature-related losses, which is particularly relevant during summer months. ### How does the Astronergy ASTRO N7s panel perform in hot weather — does it lose a significant amount of power? The n-type TOPCon cells used in the ASTRO N7s series feature an exceptionally low temperature coefficient of power (Pmax), meaning they experience smaller losses compared to conventional PERC panels. As cell temperature rises above 25 °C, the module loses proportionally less power than older p-type technologies. In practice, during Polish summers this translates to higher daily energy yields in the warmest months of the year. ### What distinguishes the double-glass construction of the Astronergy ASTRO N7s series, and why does it matter for long-term durability? Instead of a standard polymeric backsheet, a second pane of tempered glass is used, which eliminates moisture ingress and significantly reduces the risk of cell delamination. The double-glass enclosure is resistant to corrosion and UV degradation throughout the entire 30-year power warranty period. For installations in the Polish climate — where modules are exposed to large diurnal temperature swings and precipitation — this is a meaningful advantage that directly translates into extended system longevity. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/445465ASTRO-N7s_CHSM54RNsDGF-BH_1762113430_EN_20240601-f2a561afddb8.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +50 W, cooler, +2.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +35 W, cooler, +1.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +45 W, cooler, +1.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +30 W, cooler, +1.5 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +40 W, cooler, +1.5 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +40 W, cooler, +1.5 pp | | [Astronergy CHSM48RN(DG)/F-BH-440](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm48rn-dg-f-bh-440) | 440 W | -20 W, heavier, -1.0 pp | | [Astronergy CHSM48RN(DG)/F-BH-445](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm48rn-dg-f-bh-445) | 445 W | -15 W, heavier, -0.7 pp | | [Astronergy CHSM48RN(DG)(BLH)/F-BH-450](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm48rn-dg-blh-f-bh-450) | 450 W | -10 W, heavier, -0.5 pp | --- Source: https://comparepv.com/panel/astronergy-chsm54rns-dg-f-bh-460w 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.
