The CW Enerji 144PM10 series is a modern photovoltaic module based on monocrystalline PERC cells in M10 format, manufactured using a half-cut technology - meaning the cells are divided in half - which significantly reduces resistive losses and improves partial shading resistance. The panels are available in two aesthetic variants: the classic HC-MB and the Black Series, featuring a black frame and black rear film, designed for installations where aesthetics are a key factor, such as residential rooftops or premium buildings. Each module is equipped with self-cleaning glass with an anti-reflective coating, which increases light absorption and reduces the accumulation of dirt. The IP68-rated junction box provides full protection against moisture and dust, making this series suitable for use in demanding atmospheric conditions. The structural strength of the panels against wind and snow loads makes them an ideal choice for both rooftop and ground-mounted installations. The manufacturer offers a 30-year performance warranty and a 12-year product warranty, which confirms the high quality of the product.

What owners get
Efficiency at the top of its segment

The CWT550 achieves a module efficiency of 21.28%, matching direct peer comparables: IBC Solar 182M Half Cell (21.28%) and Goldi Solar GS10-B144-TF and S-Energy SL65-72BGJ (both 21.3%). The gap versus best-in-class rivals is just 0.02 percentage points — negligible in real-world energy yield.

30-year linear power warranty + IP68 junction box

The manufacturer provides a 30-year linear power output warranty and an IP68-rated junction box, guaranteeing full protection against dust ingress and continuous water immersion. This combination sets the series apart from many competitors that offer only a 25-year power warranty and IP67 protection.

High mechanical load ratings

The module withstands a snow load of 5,400 Pa and a wind load of 2,400 Pa, exceeding the IEC 61215 minimum requirements (2,400/2,400 Pa). The 5,400 Pa snow load rating makes the series well-suited for installation in Polish climatic conditions characterized by heavy snowfall.

Half-cut M10 PERC with anti-reflective coating

The M10 format (182×91 mm) in a 144 half-cut cell configuration reduces resistive losses by approximately 50% compared to full-cell designs and improves performance under partial shading conditions. The self-cleaning glass with AR coating minimizes reflection losses, increasing real-world annual energy yield in urban, high-soiling environments.

1,500 V DC system voltage

Support for 1,500 V DC systems enables longer strings with fewer inverters and lower BoS costs — a meaningful advantage for commercial rooftop and ground-mount installations above 100 kWp.

Trade-offs
Aging P-type PERC technology

In 2025–2026, the market is shifting en masse toward N-type TOPCon cells, which exhibit a degradation rate of 0.4–0.5%/year versus 0.6–0.8%/year for PERC and are free from LID (Light-Induced Degradation). Over a 30-year system lifetime, this difference can translate to a real yield loss of 3–5% of total energy production relative to equivalent TOPCon modules.

Fire safety Class C (not Class A)

The series datasheet confirms a fire safety Class C rating per IEC 61730. This may represent a formal barrier to installation on public-use building rooftops or in locations near property boundaries where local building codes mandate Class A.

No BNEF Tier 1 status

CW Enerji does not appear on published BNEF Tier 1 Module Manufacturer lists (as of 2025–2026), which limits bankability when seeking project financing from independent commercial lenders. For residential prosumer installations this is inconsequential, but for utility-scale PV projects above 1 MWp it may trigger additional due diligence requirements from financing parties.

Monofacial module only

The 144PM10 series has no bifacial variant (is_bifacial: false). For ground-mount installations on high-albedo surfaces or systems with single-axis trackers, bifaciality can increase energy yield by 5–15%. The manufacturer offers a separate bifacial line (CWT550-144PMB10), but it is not part of this series.

Common questions

6 answered
What efficiency do the CW Enerji 144PM10 panels achieve, and what is their peak power output?
The 550 Wp model in the CW Enerji 144PM10 series achieves a module efficiency of 21.29%, placing it among the top-tier PERC-class panels available on the market. The maximum power current (Imp) is 13.29 A at a maximum power voltage (Vmp) of approximately 41.4 V. This performance is the result of M10 monocrystalline cell technology combined with a half-cut cell configuration, which minimizes resistive losses and improves energy yield under partial shading conditions.
What warranty is provided for the CW Enerji 144PM10 series panels?
The manufacturer provides a 12-year product warranty covering material and workmanship defects, as well as a 30-year performance warranty, during which the module is guaranteed to retain a specified percentage of its nominal power output. This represents one of the longer warranty standards currently available on the market, confirming the reliability of the investment over multiple decades.
What is the difference between the Black Series variant and the standard HC-MB variant in the 144PM10 series?
The HC-MB variant features a classic silver aluminum frame and a white backsheet, while the Black Series is equipped with a black frame and a black backsheet. The difference is purely aesthetic — the electrical parameters and warranty terms remain identical across both variants. The Black Series is chosen by investors who prioritize a uniform, premium appearance for installations on residential rooftops or high-end commercial properties.
Can the CW Enerji 144PM10 panels withstand high wind loads and heavy snow accumulation?
Yes, the 144PM10 series structure is certified for a wind load of up to 2,400 Pa and a snow load of up to 5,400 Pa. These values are sufficient for the vast majority of locations in Poland, including mountain and coastal areas with elevated climatic load requirements. The panel operates reliably across a temperature range of -40°C to +85°C.
Is the 144PM10 series suitable for rooftop installation on a residential building?
Yes, the modules — measuring 2279×1134×35 mm and weighing approximately 29 kg — are compatible with standard mounting systems used on both pitched and flat roofs. The half-cut cell technology improves resilience to shading caused by chimneys or dormer windows, while the available Black Series variant provides the aesthetic quality valued in single-family residential construction. The IP68-rated junction box eliminates the risk of moisture-related issues beneath the roofing material.
Is the CW Enerji 144PM10 a monofacial or bifacial panel?
The 144PM10 series consists of monofacial panels — they do not feature bifacial functionality. This means that energy is generated exclusively by the front surface of the module. This design is well-suited for typical rooftop installations where reflected irradiance from the ground surface cannot be effectively utilized. It also enables a lower price point while maintaining high module efficiency of over 21%.
