Space saver, no clear weak spot
Astronergy ASTRO N7s 2.0 (CHSM48RN(DG)/F-BH) modules are designed for maximum yield from limited rooftop space - without compromising on aesthetics and durability. The application of n-type TOPCon 5.0 cells helps maintain high efficiency even in real-world conditions, not just under ideal sunlight, translating to more stable performance throughout the year.
A key feature is the ZBB (zero busbar) technology, which minimizes losses due to shading and connection resistance, supporting better module reliability over the long term. The double-glass variant enhances resistance to environmental factors and micro-cracking, which is appreciated by investors prioritizing long-term, trouble-free operation.
Thanks to the black light redirecting film, the module achieves a more uniform black appearance while improving light management within the panel structure. This is a smart choice for residential and premium segments, where both performance and discreet roof integration matter.

Signals from the data
Residential, commercial, shaded-installations and hot-climate.
Top 20% of the TOPCon 450-500 W segment, against a median of 225.2.
Top 22% of the TOPCon 450-500 W segment, against a median of 22.52%.
The 475 Wp variant achieves 23.8% module efficiency, matching the JA Solar JAM54D40 LB and Sun Earth TITAN Dual Glass. This places it among the leading performers in the 48-cell, 182 mm format segment, delivering more kWh per m² of roof area.
The n-type TOPCon 5.0 cells limit power loss at elevated temperatures to –0.29%/°C, versus the typical –0.35%/°C of legacy PERC cells. The 0.06 percentage-point/°C advantage translates to approximately 2–3% higher energy yield during summer operation at a cell temperature of 60°C.
The manufacturer guarantees ≥87.4% of rated power after 30 years, with linear degradation ≤0.4%/year (years 2–30) and ≤1.0% in year one. Comparable peers such as JA Solar and LONGi typically offer 25-year warranties or similar terms with a lower end-of-life power floor.
The 2.0+2.0 mm dual-glass design eliminates the rear backsheet, which is susceptible to cracking and delamination, while Zero Busbar (ZBB) technology reduces thermal stress on cells and lowers interconnect resistance. The result is enhanced resistance to microcracks and moisture ingress over decades of field operation.
Astronergy (Chint Group, est. 2006) maintains uninterrupted Tier 1 status per BloombergNEF and appears on the bankable manufacturers list as of Q1 2026. This confirms lender acceptance of the modules in project-finance transactions without recourse — a critical consideration for debt-financed PV installations.
The dual-glass construction increases module weight to approximately 24.5 kg, compared to ~21–22 kg for typical single-glass modules of equivalent power class. This may necessitate a structural assessment of older roof frameworks and complicates single-person installation, particularly on steep-pitch roofs.
- Efficiency of 23.0% matches the TOPCon 450-500W median
- Power density of 230.2 W/m² packs 5.0 W/m² more into the same footprint vs TOPCon 450-500W median (225.2 W/m²)
- Temperature coefficient of -0.29%/°C matches the TOPCon 450-500W median
- Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof
- #1919 for efficiency, #2165 for temperature performance out of 14005 panels
