Astronergy ASTRO N7 Bifacial series is designed to maximize energy gains in real-world operating conditions - even when the weather and light angle are not ideal. Its key advantage lies in the combination of n-type TOPCon cells with a bifacial structure, enabling the module to effectively capture energy from the rear side as well, for instance, on a bright surface, flat roofs, or ground installations. The application of SMBB (multi-string) architecture improves current collection and increases resistance to microcracks, translating into more stable long-term performance. In practice, this series also stands out for its excellent performance under low-light conditions - during overcast weather, fog, or smog. Additional support is provided by the Light Redirecting Film and double-coated glass, which enhance "light capture" and laminate durability. ASTRO N7 Bifacial is a suitable choice for utility-scale PV farms, C&I projects, and investments where lower system costs and predictable energy yield over the years are key.

What owners get
22.8–23% Efficiency at the Top of Its Segment

The 22.8–23% efficiency range positions the series on par with direct competitors (HT-SAAE HT66-18X at 23%, Weran Solar LR7-72HTH at 23%), meaning Astronergy concedes no percentage points in conversion efficiency against the lowest-cost alternatives in the 615–620 Wp power class.

Degradation ≤0.4%/year Over 30 Years

The official datasheet (600–620 W, February 2024) confirms first-year degradation of ≤1.0% and ≤0.4% for years 2–30. Assuming 0.4%/year, the module retains >87% of rated power after 30 years — one of the stronger long-term performance figures in the 66-cell TOPCon segment.

Bifacial Rear-Side Yield of Up to +25%

The dual-glass bifacial construction enables real-world rear-side energy gains of up to 25% under high-albedo ground conditions (light gravel, TPO membrane, snow). In ground-mount and flat-roof installations, this translates into a measurably lower LCOE without increasing module count.

SMBB + Light Redirecting Film — Durability and Low-Irradiance Performance

The Super Multi-Busbar (SMBB) architecture shortens the current path between cells, minimizing resistive losses and the risk of micro-crack propagation. The Light Redirecting Film directs diffuse irradiance onto the cells — a benefit especially visible under overcast skies and at low sun angles, conditions under which PERC installations lose proportionally more power.

BNEF Tier 1, 56 GW of Manufacturing Capacity (Q2 2025)

Astronergy (CHINT) is listed on the BloombergNEF Tier 1 roster, confirming project finance bankability without additional lender requirements for manufacturer guarantees. Annual manufacturing capacity of 56 GW eliminates supply-chain disruption risk for multi-megawatt procurement contracts.

Trade-offs
15-Year Product Warranty

The product warranty (materials and workmanship) covers 15 years, whereas several Tier 1 manufacturers in the same power class — including LONGi and JA Solar in their premium lines — offer 25-year product warranties. For C&I projects with a financing horizon of 20+ years, this gap may require additional insurance coverage or an explicit risk buffer in the financial model.

Notes from the database
  • Efficiency of 22.8% matches the TOPCon 600-650W median

Common questions

6 answered
What warranty does the Astronergy ASTRO N7 Bifacial series carry?
The ASTRO N7 Bifacial series comes with a 15-year product warranty covering manufacturing defects and workmanship, along with a 30-year linear power output warranty. Degradation is less than 1% in the first year and no more than 0.4% per year in subsequent years. After 30 years, the module is guaranteed to retain at least 87.4% of its nominal power output. As a Tier 1 manufacturer, Astronergy is widely recognized as a financially stable guarantor of these long-term commitments.
Are the ASTRO N7 Bifacial panels suitable for flat-roof installations or ground-mounted systems?
Yes, these are among the best-suited applications for this series. The bifacial dual-glass construction allows the module to generate additional energy from its rear side by capturing light reflected off bright surfaces such as gravel, concrete, or roofing membrane. On flat roofs and ground-mounted PV farms with optimal clearance beneath the modules, the manufacturer reports measurable bifacial energy yield gains. The series is explicitly recommended for C&I projects and utility-scale PV farms.
Is the TOPCon technology used in the ASTRO N7 series superior to standard PERC panels?
N-type TOPCon cells offer higher efficiency — 21.8–22.8% in this series — and a lower temperature coefficient compared to typical p-type PERC cells. This translates to reduced power losses on hot days. TOPCon also demonstrates improved resistance to potential-induced degradation (PID) and lower long-term degradation rates, resulting in higher cumulative energy yield over the full operational lifetime of the installation.
How does the ASTRO N7 Bifacial series perform under cloudy conditions or low irradiance?
The ASTRO N7 Bifacial series outperforms older technologies under diffuse light conditions. Key contributors include the SMBB (Super Multi Busbar) cell architecture, a Light Redirecting Film, and dual-layer anti-reflective coated glass, all of which improve photon capture at low irradiance levels. Astronergy has earned a Top Performer designation from the independent testing laboratory PVEL (PV Evolution Labs), confirming the modules' high reliability under demanding climatic conditions.
Is Astronergy a reliable solar panel manufacturer?
Astronergy is a Chinese manufacturer ranked among the global Tier 1 suppliers, indicating financial stability and the long-term capacity to honor warranty obligations. The company is part of the CHINT Group and consistently receives Top Performer recognition from the independent laboratory PVEL. The ASTRO N7 Bifacial series is available on the Polish and broader European market through authorized distributors.
What is the maximum power output of the Astronergy ASTRO N7 Bifacial series, and what types of installations is it designed for?
The ASTRO N7 Bifacial series is available in configurations up to 620 W, with newer variants reaching up to 635 W. These high-power 72-cell modules are primarily designed for utility-scale PV farms, industrial and commercial (C&I) installations, and ground-mounted projects, where high per-unit power output translates directly into lower balance-of-system (BoS) costs and faster return on investment. This series is not typically designed for residential rooftop installations on single-family homes.
