The Astronergy ASTRO N7 Pro CHSM66RN(DG)/F-BQ series is a new generation of bifacial modules designed for investors who want maximum energy yield from limited roof or ground space. The panel uses next-generation N-Type TOPCon cells, which thanks to improved surface passivation and higher light-capturing capability reduce power degradation and improve long-term generation stability. The quarter-cut cell design lowers internal current, reducing the risk of hot spots and increasing the module's resistance to microcracks and mechanical stress. The bifacial glass-glass construction allows the module to capture light reflected from the ground, meaningfully increasing total energy yield without expanding the installation footprint, which in turn lowers the project's LCOE. In addition, densely packed, low-stress cell interconnections increase the module's effective active area. A sealed IP68-rated junction box provides durable protection against moisture and contamination even in harsh operating conditions. This solution is aimed at installers and investors in solar farms and large commercial installations who need high reliability, long-term performance, and a competitive cost of generated energy.

What owners get
Up to 24.8% efficiency – clearly above peers

Efficiency of 23.9-24.8% is roughly 3 percentage points higher than comparable 670 Wp competitor modules (Hiwatt HW-M12/132H 21.6%, Techwise Summit 21.57%, Resun RS9H-M 21.57%), translating into approximately 13-15% higher energy yield from the same roof or ground area.

Low temperature coefficient of -0.26%/°C

Per the datasheet, the power temperature coefficient is -0.26%/°C, better than the typical -0.35 to -0.40%/°C of older PERC cells, resulting in a smaller power drop on hot days and higher annual yield in warmer climates.

30-year power warranty at 88.85%

The manufacturer guarantees 88.85% of nominal power after 30 years (99% after the first year), a premium standard for N-type TOPCon technology that supports lower LCOE over the investment's long-term horizon.

Astronergy ranked among Tier-1 BNEF leaders

Astronergy has approximately 56 GW of annual manufacturing capacity and appears in the BloombergNEF Tier 1 ranking for Q2 2026 as the second-largest manufacturer after Canadian Solar, confirming the series' bankability for project financing.

Bifacial glass-glass build with quarter-cut cells

Dual 2 mm glass and quarter-cut cells (264 segments) reduce internal current, lowering the risk of hot spots and microcracks, while capturing reflected light from the ground surface to boost total energy yield.

Trade-offs
Large module format – installation requirements

Dimensions of 2382x1134 mm and a weight of 32 kg (glass-glass) may require reinforced mounting structures and two-person installation, a typical constraint for large-format panels above 645 Wp that can raise logistics and installation costs versus smaller modules.

New product without long field track record

Launched in 2026, the series lacks the multi-year field performance data available for established ASTRO N7 series (2023-2025), which may matter to investors evaluating long-term operational risk in project due diligence.

Notes from the database
  • At 24.1% efficiency, this panel is 1.7pp above typical TOPCon 650-700W modules (median: 22.4%)
  • Power density of 240.6 W/m² packs 16.9 W/m² more into the same footprint vs TOPCon 650-700W median (223.7 W/m²)
  • Temperature coefficient of -0.26%/°C vs median -0.29%/°C means ~1% less power loss at 65°C
  • Weight of 32.0 kg (2.6 kg below TOPCon 650-700W median of 34.6 kg) allows easier transport and roof mounting
  • 85% bifaciality enables rear-side power generation, boosting yield by 4-13% on reflective surfaces

Common questions

6 answered
How much power does the Astronergy ASTRO N7 Pro CHSM66RN(DG)/F-BQ panel generate?
Modules in the ASTRO N7 Pro series reach a maximum power output of up to 670 Wp. This high performance results from the use of N-Type TOPCon cells combined with bifacial technology, which lets the panel generate extra energy from its rear side by capturing light reflected off the ground.
What is the difference between TOPCon technology and conventional PERC cells?
N-Type TOPCon cells, used in the ASTRO N7 Pro series, offer better surface passivation than older PERC cells, resulting in lower power degradation over time and higher efficiency, especially at elevated temperatures. In practice, this means a higher and more stable energy yield throughout the system's lifetime.
Is a bifacial glass-glass panel worth it on a roof, or only for ground-mount systems?
Bifacial construction delivers the greatest benefit when installed over a light, reflective surface, such as ground-mount systems, flat roofs with light-colored covering, or freestanding structures with adequate clearance. On a typical pitched roof the bifacial gain is limited, but the panel still performs well as a standard high-efficiency monofacial-equivalent module.
What warranty comes with the Astronergy ASTRO N7 Pro panels?
The manufacturer provides a 15-year product warranty along with a 30-year linear power output warranty. Astronergy is a Tier 1 manufacturer, which adds further confidence that warranty obligations will be honored over the system's long service life.
Does the IP68 junction box protect against moisture and dust in harsh conditions?
Yes, the sealed junction box used in this series carries an IP68 rating, the highest standard for water immersion and dust protection. This ensures reliable operation even in humid climates, dusty environments, or coastal and industrial installations.
What kind of installations are the ASTRO N7 Pro CHSM66RN(DG)/F-BQ panels best suited for?
This series was designed primarily for utility-scale solar farms and large commercial or industrial installations where maximizing energy yield from limited space is critical. The combination of high module power, bifacial technology, and quarter-cut cells that reduce hot-spot risk drives down the levelized cost of energy (LCOE) at scale.
