These are critical parameters for the Polish climate, with its frost cycles and severe convective storms. - **Power Tolerance 0~+5 Wp** - 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. ## Cons - **Series Discontinued (EOL 2024)** - 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. - **P-Type PERC - Previous-Generation Technology** - 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. ## About this series 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. ## Notable figures - At 20.6% efficiency, this panel is 1.2pp above typical \*\*PERC 0-400W\*\* modules (median: 19.4%) - 205.8 W/m² power density - 11.7 W/m² more than \*\*PERC 0-400W\*\* median (194.2 W/m²), more power per roof area - Temperature coefficient of -0.35%/°C matches the \*\*PERC 0-400W\*\* median - At 19.1 kg, this panel is 1.4 kg lighter than \*\*PERC 0-400W\*\* median (20.5 kg) - easier handling during installation - In the top 79% for efficiency among all PERC panels ## Questions ### Is the Astronergy CHSM60M-HC (166) series still available for purchase? The CHSM60M-HC Monofacial (166) series has been discontinued by Astronergy and is no longer in active production. Isolated units may still exist in distributor warehouses, but these should not be relied upon when planning a new installation. If you need to expand an existing system based on this series, contact your supplier directly to inquire about remaining stock or a suitable replacement module. ### What warranty does the Astronergy CHSM60M-HC (166) series carry? Modules in the CHSM60M-HC (166) series are covered by a 12-year product warranty against material and workmanship defects, as well as a 25-year linear power output warranty. After 25 years of operation, the module is warranted to retain at least 84.8% of its nameplate power. Astronergy is a Tier 1 manufacturer, which reflects the financial standing required to honor these long-term warranty commitments. ### What is the rated power output of the Astronergy CHSM60M-HC (166) panel, and how many cells does it contain? The top-tier model in the CHSM60M-HC (166) series achieves a rated output of 385 Wp under Standard Test Conditions (STC). The module is built from 120 monocrystalline PERC cells arranged in a half-cut configuration, which reduces internal resistive losses and improves tolerance to partial shading compared to a conventional 60-cell full-cell layout. ### Does the PERC half-cut technology in the CHSM60M-HC (166) series make a meaningful difference on a shaded roof? Yes, and quite noticeably. Splitting each cell in half means that shading on one section of the module - caused by, for example, a chimney or antenna - does not suppress output across the entire module as severely as it would in older full-cell designs. The PERC technology also improves efficiency under diffuse irradiance, which is common in temperate climates with frequent overcast conditions. This is a practical advantage for rooftops with obstructions or complex geometry. ### How much does the Astronergy CHSM60M-HC (166) panel weigh, and is it compatible with a standard pitched roof installation? The module weighs approximately 19.1 kg and has dimensions of 1755 × 1038 × 30 mm. These are standard form-factor specifications for the 385 W class and are fully compatible with most widely used racking systems (Schletter, K2, Esdec). For installations on typical pitched roofs with tile or metal sheet covering, no custom mounting structures are required - the module fits standard rails and clamps without modification. ### Is Astronergy a reliable photovoltaic module manufacturer? Astronergy (the solar brand of CHINT Group) is a Chinese manufacturer classified as Tier 1 by Bloomberg NEF, indicating verified financial capacity to honor long-term warranty obligations. The company holds IEC and UL certifications, and its products have been deployed across European markets for over a decade. Tier 1 status is an important criterion when selecting modules for installations subject to project financing or insurance underwriting requirements. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/234838767897002800-b2b99b96a4cf.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | -45 W, cooler, +2.5 pp | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | -45 W, cooler, +2.5 pp | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | -35 W, +2.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | Lighter, +2.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | Lighter, +2.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/2\*4\*20)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-2-4-20) | 400 W | +25 W, +2.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/4\*4\*40)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-4-4-40) | 400 W | +25 W, +2.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/2\*4\*19)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19) | 380 W | Lighter, +2.4 pp, +5 yr warranty | | [Maxeon SPR-MAX3-400-COM](https://comparepv.com/panel/maxeon-spr-max3-400-com) | 400 W | Cooler, +2.0 pp, +15 yr warranty | | [Maxeon SPR-MAX3-425-R](https://comparepv.com/panel/maxeon-spr-max3-425-r) | 425 W | Cooler, +1.8 pp, +15 yr warranty | | [Astronergy CHSM60M-HC 370W](https://comparepv.com/panel/astronergy-chint-solar-zhejiang-co-ltd-chsm60m-hc-370w) | 370 W | -0.3 pp | | [Astronergy CHSM60M-HC 380W](https://comparepv.com/panel/astronergy-chint-solar-zhejiang-co-ltd-chsm60m-hc-380w) | 380 W | +0.3 pp | | [Astronergy CHSM60M-HC 385W](https://comparepv.com/panel/astronergy-chint-solar-zhejiang-co-ltd-chsm60m-hc-385w) | 385 W | +10 W, +0.5 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +135 W, cooler, +4.4 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +120 W, cooler, +4.2 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +130 W, cooler, +4.1 pp | --- Source: https://comparepv.com/panel/astronergy-chint-solar-zhejiang-co-ltd-chsm60m-hc-375w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
