This performance is close to that of the GCL SIROT NT10/72GDF (23.42%), placing the series at the top of the 605 W segment. - **Low temperature coefficient of Pmax: -0.29%/°C** - n-type TOPCon cells exhibit a temperature coefficient of -0.29%/°C, compared to the typical -0.35%/°C for PERC technology. Under Polish conditions (module temperatures of 60-75°C during the summer), this translates to approximately 1.5-2.5% lower power losses at high solar irradiance compared to older technologies. - **30-year linear warranty on power output, degradation ≤0.40%/year** - The manufacturer guarantees ≥87.4% power output after 30 years, with an annual degradation of ≤0.40% (years 2-30). Solar panels with PERC technology typically offer 25-year warranties with a power output of approximately 84.8% after that period. Therefore, the ASTRO N5 offers both a longer lifespan and a higher final power output. - **Glass-glass + bifaciality: higher efficiency and durability** - The dual-layer construction (2 mm + 2 mm) eliminates the risk of delamination of the rear foil and significantly reduces moisture penetration, thereby extending the lifespan of the module. The bifacial design allows for the recovery of an additional 5-25% of energy (depending on the albedo of the substrate: light gravel ~0.35, TPO membrane ~0.20) without increasing the occupied surface area. - **Astronergy - Ranked among the top 6 most bankable projects in the BNEF 2023 report** - Astronergy ranked 6th in the BloombergNEF 2023 bankability ranking for all PV module manufacturers worldwide, which confirms its ability to secure financing from independent commercial banks and facilitates the acquisition of project finance for PV farms and industrial installations. ## Cons - **Weight ~32 kg - roof load** - The glass-glass (2+2 mm glass) construction increases the module's weight to approximately 31-32 kg, compared to approximately 28 kg for a glass-backsheet module. For roof-mounted installations, it is necessary to verify the roof's load-bearing capacity, and installation typically requires the work of two installers or the use of specialized mounting systems, which can increase labor costs. - **One power variant (605 W) - limited flexibility** - The series offers only one power option (605 W), which makes it difficult to optimally match the number of modules in a string to inverters with smaller voltage ranges (MPPT) or to small-scale (prosumer) installations with an area of less than approximately 20 m². Competitive series (e.g., GCL SIROT NT10/72GDF) offer a wider range of power options. ## About this series Astronergy ASTRO N5 Bifacial (CHSM72N(DG)/F-BH) are glass-glass bifacial modules engineered for maximum energy yield where every square meter counts, alongside long-term operational stability. The implementation of **n-type TOPCon cells** helps mitigate common losses found in older technologies and maintains high efficiency even under low irradiance conditions. A key advantage is **bifaciality**-the module harnesses reflected light off the ground, thereby significantly boosting energy production on bright roofs, gravel surfaces, or ground-mounted installations without additional panels. Thanks to **double-sided glass**, this series is better equipped for challenging environmental conditions and long-term operation, making it appealing to investors seeking reliable performance. It's an excellent choice for utility-scale PV farms, commercial and industrial installations, and large rooftop systems-especially when aiming to reduce Balance of System (BOS) costs through **high single-module power** and simplifying string designs. ## Notable figures - 23.4% module efficiency - 0.6pp better than the \*\*TOPCon 600-650W\*\* median of 22.8% - At 234.2 W/m² power density, this panel generates 6.5 W/m² more per unit area than \*\*TOPCon 600-650W\*\* median (227.7 W/m²) - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 600-650W\*\* median - Weight of 31.1 kg (1.7 kg below \*\*TOPCon 600-650W\*\* median of 32.8 kg) allows easier transport and roof mounting - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof ## Questions ### What warranty is offered on the Astronergy ASTRO N5 Bifacial CHSM72N(DG)/F-BH panels? The ASTRO N5 Bifacial series comes with a 15-year product warranty covering manufacturing defects and workmanship, along with a 30-year linear power output warranty. After 30 years of operation, the module is guaranteed to retain at least 87.4% of its nominal power. This is one of the longest warranty standards available in the market and is backed by an international insurance provider, which significantly strengthens the credibility of the manufacturer's commitment. ### What are the benefits of bifacial technology in the ASTRO N5 panels, and is the premium worth it? Bifacial technology means the module generates electricity from both its front and rear surfaces by capturing light reflected from the ground or surrounding surfaces. In practice, when installed over light-colored gravel, a white roofing membrane, or as a ground-mounted system with adequate ground clearance, real-world energy yield can increase by 5-15% without adding extra panels. Given a front-side power rating of up to 605 Wp, this translates into measurable savings on balance-of-system (BoS) costs in larger-scale projects. ### Will the Astronergy ASTRO N5 605 Wp panels perform well in Poland's climate with frequent overcast skies? Yes. The n-type TOPCon cells used in this series feature a lower temperature coefficient (-0.29%/°C) and superior response to diffuse irradiance compared to older PERC cells. This means that under typical Polish weather conditions - where partial cloud cover is common throughout the summer - the module maintains a relatively high energy output relative to its rated power, outperforming conventional technologies in low-light scenarios. ### How much does a single ASTRO N5 Bifacial module weigh, and will a standard roof structure support it? A single module weighs approximately 32.1 kg with dimensions of 2278 × 1134 × 30 mm. This is heavier than a typical 60-cell panel, so a structural load assessment of the roof is advisable before installation, particularly on older buildings. On new industrial facilities and steel-frame structures, this weight is generally not a concern; moreover, the large module format reduces the total number of modules required and simplifies load distribution across the mounting system. ### How does the glass-glass construction of the ASTRO N5 series differ from a standard module with a polymer backsheet? In glass-glass modules, the conventional polymer backsheet is replaced with a second pane of tempered glass, eliminating the primary failure modes associated with backsheets: cracking, discoloration, and moisture ingress. The result is enhanced protection of the solar cells against weathering, greater resistance to Potential Induced Degradation (PID), and improved long-term mechanical durability. For installations with a 25-30-year horizon - especially in challenging microclimates - this represents a significant advantage over standard backsheet designs. ### Is the Astronergy ASTRO N5 Bifacial CHSM72N(DG)/F-BH series still commercially available? Yes, the ASTRO N5 Bifacial series is actively manufactured and available on the market. Astronergy is a Tier 1 manufacturer, which ensures consistent module availability through distributors in Poland and across Europe. Prior to purchase, it is advisable to confirm current stock levels with your preferred supplier, as available volumes for specific power variants may vary depending on the season and regional demand. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/585605astro-n5-chsm72ndgf-bh-2278x1134x30-en-20250819-c8d23fcb9723.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +45 W, lighter, +1.8 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +40 W, lighter, +1.6 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -45 W, lighter, +1.4 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +35 W, lighter, +1.4 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -50 W, lighter, +1.2 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +30 W, lighter, +1.2 pp | | [Astronergy CHSM72M-HC-545](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm72m-hc-545) | 545 W | -60 W, hotter, -2.3 pp | | [Astronergy CHSM72M-HC-550](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm72m-hc-550) | 550 W | -55 W, hotter, -2.1 pp | | [Astronergy CHSM72M-HC-555](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm72m-hc-555) | 555 W | -50 W, hotter, -1.9 pp | | [Astronergy CHSM72M-HC-560](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm72m-hc-560) | 560 W | Hotter, -1.7 pp, -5 yr warranty | | [Astronergy CHSM72N-HC-565](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm72n-hc-565) | 565 W | -40 W, lighter, -1.5 pp | | [Astronergy CHSM72N-HC-570](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm72n-hc-570) | 570 W | -35 W, lighter, -1.3 pp | | [Astronergy CHSM72N-HC-575](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm72n-hc-575) | 575 W | -30 W, lighter, -1.1 pp | | [Astronergy CHSM72N-HC-580](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm72n-hc-580) | 580 W | -25 W, lighter, -0.9 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +25 W, cooler, +1.0 pp | --- Source: https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm72n-dg-f-bh-605 Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
