Middle of its segment, heavy for its output
The PHENex PS-M144(HCBF)-GG series consists of double-glass bifacial modules engineered to maximize energy yield in commercial and industrial installations. The use of 144 half-cut monocrystalline PERC cells reduces resistive losses and improves module performance under partial shading, resulting in more stable energy production in challenging irradiance conditions. Thanks to bifacial technology, the rear side of the module captures light reflected from the ground, which is especially beneficial on gravel rooftops, sandy terrain, snow-covered areas, or sites near water, where the additional energy gain can be significant. The use of a double tempered glass construction instead of a rear backsheet increases the panel's mechanical and chemical resistance, extends its lifespan, and limits LID and PID degradation. A sturdy, anodized aluminum frame ensures high resistance to wind and snow loads, making the series suitable for both large-scale solar farms and demanding rooftop installations. The PHENex series is a solution for investors seeking long-term reliability and a lower cost of energy per installed watt, backed by an extended product and power warranty.

Signals from the data
Commercial, utility-scale and shaded-installations.
Weight-limited structures.
Bottom 9% of the PERC 500-550 W segment, against a median of 53.0. Ranked 12,384th in the whole database.
The double-glass construction with a rear side active for light capture delivers, per manufacturer data, an additional 7-25% energy yield above the 550 Wp front-side rated power - particularly valuable on gravel roofs, ground-mount farms with high-albedo surfaces, or in snowy environments.
Efficiency up to 21.29% puts the series in the same league as peer comparables in this power class: IBC Solar 182M (21.28%), Goldi Solar GS10-B144-TF (21.30%), and Jetion JT SGh (21.30%) - differences are within measurement tolerance.
Tempered glass on both sides instead of a standard backsheet reduces LID and PID degradation and increases mechanical and chemical resistance, resulting in longer, more stable service life, especially in demanding environmental conditions.
The manufacturer guarantees linear power degradation down to 83.0% output at year 30, backed by a 12-year product warranty - parameters comparable to leading tier-1 manufacturers' offerings in the bifacial PERC segment.
Philadelphia Solar has operated since 2007 and appears on BNEF's Tier-1 manufacturer list, indicating documented supply to commercially bank-financed projects - a key factor in reducing risk for institutional investors.
The PHENex PS-M144(HCBF)-GG series was discontinued in 2023 (launched 2021), meaning limited availability of matching spare units and potential difficulties with warranty service or matching panels when extending an existing installation.
PERC cells in this series reach an efficiency ceiling of around 21.3%, while newer N-type TOPCon and HJT modules currently on the market offer higher efficiencies (23%+) and typically lower annual degradation rates - making this series an older technology generation compared to current tier-1 offerings.
- Efficiency of 20.9% matches the PERC 500-550W median
- At 209.0 W/m² power density, roof space requirements are typical for PERC 500-550W panels
- At -0.35%/°C, hot weather performance is typical for PERC 500-550W panels
- Weight of 32.5 kg is 4.1 kg above PERC 500-550W median (28.4 kg) - verify structural support
- 65% bifaciality enables rear-side power generation, boosting yield by 3-10% on reflective surfaces
