Space saver, no clear weak spot
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.
Ranking
Signals from the data
Commercial and utility-scale.
Top 11% of the TOPCon 600-650 W segment, against a median of 227.7.
Top 12% of the TOPCon 600-650 W segment, against a median of 22.80%.
With a 23.4% efficiency, the ASTRO N5 (605 W) module directly outperforms comparable models such as JS Solar JS210MHC120 and LEDVANCE M585~605P60UB by approximately 2 percentage points (21.37-21.40%), resulting in a significantly higher energy yield for the same roof area. 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.
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.
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.
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 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.
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.
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.
- 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
