Light for its output, no clear weak spot
The Astronergy CHSM60M-HC Monofacial (166) series are modules based on monocrystalline P-type PERC cells in a half-cut configuration, designed to minimize energy losses during daily operation of the installation. Dividing the cells in half improves the panel's performance under partial shading and helps maintain a more stable output, especially when rooftop conditions are not ideal. The monofacial glass-backsheet construction is ideal where predictability, ease of installation, and compatibility with popular mounting systems are key.
Half-cut technology stands out in practice, reducing the impact of shading on yield, PERC monocrystalline cells ensuring good efficiency under variable sunlight conditions, and high operational durability thanks to the refined module structure. This is a great choice for residential and small commercial installations, where stable performance and reliability in the Polish climate are important. Compared to the competition, the CHSM60M-HC (166) series defends itself through a sensible balance between performance, durability, and predictable behavior under real-world installation conditions.

Astronergy (Chint Group) is ranked among the six most bankable module manufacturers in the world on the BNEF Bankability list (2023), confirming the company's financial stability and its ability to honor warranty obligations throughout the full 25-year power output guarantee period.
Splitting cells in half reduces internal resistance and limits losses under partial shading - each half-row is electrically independent, so shading one section of the module has a smaller impact on the overall system energy yield.
The upper efficiency limit of the series (21.1%) surpasses comparable models such as the JA Solar JAM60D20 (20.6%) and the Solarwatt Panel Vision GM 3.0 pure (20.7%), indicating that the higher-wattage variants (380-385 Wp) were well-positioned within their price-to-performance segment.
The series datasheet confirms successful completion of a 96-hour PID test at 85 °C/85% relative humidity, as well as certified hail resistance - 25 mm ice balls at 23 m/s impact velocity. These are critical parameters for the Polish climate, with its frost cycles and severe convective storms.
The guaranteed positive-only power tolerance means no module from this series leaves the factory below its rated power output, improving yield predictability and simplifying system design.
The CHSM60M-HC (166) series reached end of life in 2024 (released 2020, discontinued 2024). Availability of new modules is limited to distributor inventory, and if a module fails or the system is expanded years down the line, achieving a visual and electrical match (Voc, Isc) with a current series may be difficult or impossible.
Since 2023, the market has shifted en masse to N-type TOPCon cells, which offer a lower LID degradation rate (N-type cells are inherently LID-free) and better temperature coefficient performance. Selecting the CHSM60M-HC (166) series in 2025 or later is a deliberate choice of an older P-type cell generation, although for many residential prosumer installations the difference in annual energy yield is not decisive.
- Efficiency of 20.3% is 0.9pp above the PERC 0-400W median (19.4%)
- Power density of 203.1 W/m² packs 8.9 W/m² more into the same footprint vs PERC 0-400W median (194.2 W/m²)
- Temperature coefficient of -0.35%/°C matches the PERC 0-400W median
- Weight of 19.1 kg (1.4 kg below PERC 0-400W median of 20.5 kg) allows easier transport and roof mounting
- In the top 84% for efficiency among all PERC panels
