On hot days (e.g., 60°C surface temperature), this difference results in approximately 3% higher hourly energy yield compared to older technologies. - **Efficiency of 22.5-23.2% - a significant advantage over key competitors** - The upper limit of 23.2% efficiency exceeds the Talesun BISTAR TP7F78M by 1.7pp (21.5%), and is equal to the Tongwei TWMND (23.2%). Furthermore, Astronergy is a Tier 1 BNEF manufacturer with a production capacity of 56 GW, making it a significant player in the industry, which is important for ensuring consistent performance across different batches. - **30-year linear warranty with an 84.95% retention rate** - The manufacturer guarantees a degradation rate of ≤1.0% in the first year and ≤0.4%/year in years 2-30, resulting in an 87.4% retention rate after 25 years and 84.95% after 30 years. Talesun and Lexron do not publish equivalent 30-year linear warranties, making ASTRO N5 a safer choice for long-term LCOE analysis. - **BNEF Tier 1 - Bankability confirmed by top 6 (2023)** - Astronergy ranked 6th in the BloombergNEF 2023 bankability ranking, which is crucial for projects financed by banks or covered by investment insurance. LeXron and smaller brands in this category do not have this ranking, which could hinder external financing when using their products. - **Bifacial + SMBB: Double energy yield** - The bifacial design allows for an additional gain of typically 10-20% from the rear side of the module (depending on the albedo of the substrate). SMBB (Selective Metal Back Contact) connections reduce the current flow resistance and limit the propagation of microcracks, which translates to a longer lifespan for the cells under variable thermal loads. ## About this series The Astronergy ASTRO N5 solar panel series represents a breakthrough in performance thanks to the use of advanced **N-type TOPCon cells**. This modern architecture effectively eliminates the problem of light-induced degradation (LID) and guarantees stable system operation even at high temperatures, which directly translates into higher annual energy yields. Models from this line are characterized by **exceptional efficiency exceeding 22 percent**, which allows for maximum utilization of limited roof space while maintaining high generator power. Thanks to the use of multi-busbar SMBB connections, the panels handle current flow better and show less susceptibility to micro-cracks. **Excellent low-light performance** ensures that the installation works effectively even on cloudy days, which is key for investments in Polish climate conditions. It is a solution dedicated to both individual prosumers and business projects looking for the best price-to-quality ratio. The use of **bifacial technology** in selected variants further increases energy production from the back of the module, making the ASTRO N5 series a leader in terms of LCOE cost optimization. The entire structure features **increased mechanical resistance** to extreme snow loads and strong wind gusts. ## Notable figures - At 22.5% efficiency, this panel is on par with typical \*\*TOPCon 550-600W\*\* modules - Power density of 224.5 W/m² matches the \*\*TOPCon 550-600W\*\* median - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 550-600W\*\* panels - Ranked #4281 out of 14129 panels for efficiency in the database ## Questions ### What warranty is provided with Astronergy ASTRO N5 solar panels? The Astronergy ASTRO N5 series comes with a 15-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty. The manufacturer guarantees that after the first year the panel will retain at least 99% of its nominal power, with annual degradation not exceeding 0.4% from the second year onward. After 30 years of operation, the module is warranted to produce at least 84.95% of its rated power output. This is one of the most comprehensive warranty standards currently available on the market. ### How does the TOPCon technology in the ASTRO N5 series differ from conventional mono PERC panels? The TOPCon (Tunnel Oxide Passivated Contact) cells used in the ASTRO N5 series belong to the N-type cell generation, which eliminates the LID (Light-Induced Degradation) phenomenon that caused older PERC modules to lose power output within the first weeks of operation. The ASTRO N5 achieves module efficiency exceeding 22%, whereas typical mono PERC panels reach 20-21%. This translates into significantly higher power yield from the same roof area and better energy production over the full 30-year system lifetime. ### Are the Astronergy ASTRO N5 panels bifacial, and does this realistically increase energy production? Select variants of the ASTRO N5 series are manufactured using bifacial technology with glass on both sides of the module. The rear surface captures light reflected from the ground, delivering an additional 5-15% of energy output depending on the albedo of the underlying surface. The greatest gain is achieved over light-colored facades, white gravel, or snow. On dark-pitched rooftops the effect is reduced but still measurable. For ground-mounted systems and flat-roof installations, bifacial modules are a particularly cost-effective choice. ### How do the ASTRO N5 panels perform on overcast days and during Polish winters? The ASTRO N5 series delivers above-average low-light performance, which is critical in the Polish climate with its many overcast days. N-type TOPCon cells exhibit better energy harvesting under diffuse irradiance conditions compared to P-type PERC cells. The low temperature coefficient (-0.29%/°C) also means that on cold, sunny winter days the modules can operate with exceptionally high instantaneous power output, since lower cell temperatures are conducive to higher peak power. ### How many cells does the ASTRO N5 panel contain, and does SMBB technology protect against microcracks? Popular models in the ASTRO N5 series (up to approximately 605 W) are based on 72 half-cut cells in the 182 mm format, interconnected using SMBB (Smart Multi Busbar) technology. The greater number of thinner busbars means that even if an individual cell develops a microcrack, the module loses only a minimal fraction of its power output. SMBB also reduces resistive losses and mechanical stress during thermal expansion, directly contributing to a longer service life of the panel. ### Is the Astronergy ASTRO N5 series suitable for a residential 10-15 kW system, and is it compatible with popular inverters? Yes, the ASTRO N5 is designed for both residential prosumer applications and commercial-scale projects. With a peak power of up to 600 Wp, a 10 kW system can be built using as few as 17 modules, minimizing the number of connections and reducing installation time. The electrical parameters (voltages and currents) are compatible with the input specifications of inverters from leading manufacturers (SMA, Fronius, Huawei, SolarEdge, Growatt). It is nonetheless advisable to verify the specific model's datasheet against the selected inverter's Voc and Isc limits before purchase. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/580600ASTRO-N5_CHSM72NDGF-BH_2278x1134x30_EN_20240601-1-a457d868c017.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.3 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +2.1 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +50 W, cooler, +1.9 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | -30 W, 16 kg 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, lighter, -1.4 pp | | [Astronergy CHSM72M-HC-550](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm72m-hc-550) | 550 W | Hotter, lighter, -1.2 pp | | [Astronergy CHSM72M-HC-555](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm72m-hc-555) | 555 W | Hotter, lighter, -1.0 pp | | [Astronergy CHSM72M-HC-560](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm72m-hc-560) | 560 W | Hotter, lighter, -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, lighter, -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, lighter, -0.4 pp | | [Astronergy CHSM72N-HC-575](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm72n-hc-575) | 575 W | Lighter | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +70 W, lighter, +2.7 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +65 W, lighter, +2.5 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +60 W, lighter, +2.3 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +55 W, lighter, +2.1 pp | --- Source: https://comparepv.com/panel/astronergy-chsm72n-dg-f-bh-580-1 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.
