Solid all-round for its segment
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.

Signals from the data
Residential, commercial and shaded-installations.
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.
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.
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.
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.
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.
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.
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.
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.
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.
- At 20.9% efficiency, this panel is on par with typical PERC 500-550W modules
- At 209.0 W/m² power density, roof space requirements are typical for PERC 500-550W panels
- Temperature coefficient of -0.35%/°C matches the PERC 500-550W median
- Ranked #10294 out of 14005 panels for efficiency in the database
