Warranty pick, heavy for its output
The PS-M156(HCBF)-GG-xxxW series, part of Philadelphia Solar's PHENex lineup, is built for commercial, industrial, and utility-scale installations where maximizing output from every square meter of roof or ground space matters. The panel uses half-cut cells sized at 182 mm, which reduces losses from partial shading and microcracks while improving temperature coefficients compared to full-cell modules. The bifacial technology captures additional light reflected off the rear side of the panel, boosting total energy yield without increasing the footprint of the array. A construction based on double glass and an AL 6063-T5/6005-T6 aluminum frame delivers strong mechanical durability - the module withstands loads up to 5400 Pa on the front and 2400 Pa on the back, making it a solid choice for regions with heavy snow loads or strong winds. The 10-busbar layout lowers internal resistance and improves current collection across the cell. Backed by certified resistance to PID, salt mist, and ammonia, the panel performs reliably in demanding environments, including coastal areas and agricultural sites. Manufactured on automated robotic production lines in Jordan, it delivers consistent quality, while the long linear power warranty confirms low degradation over the module's lifetime.
Ranking
Signals from the data
Commercial and utility-scale.
Weight-limited structures.
Top 25% of the PERC 550-600 W segment, against a median of 27 yrs.
Bottom 8% of the PERC 550-600 W segment, against a median of 52.7. Ranked 12,311th in the whole database.
Half-cut cells sized at 182 mm reduce losses from microcracks and partial shading while improving temperature coefficients versus full-cell modules. Bifacial light absorption captures additional rear-side energy, boosting yield per square meter without expanding the installation footprint.
Double glass and an AL 6063-T5/6005-T6 aluminum frame give the module a load rating of up to 5400 Pa front / 2400 Pa rear, above the typical market standard (2400/2400 Pa), making it well suited to sites with heavy snow loads or strong wind.
The manufacturer offers a 30-year power warranty alongside a 12-year product warranty - a term comparable to leading tier-1 manufacturers, improving project bankability and long-term yield predictability.
PID, salt mist, and ammonia resistance certifications allow deployment in coastal installations and agricultural (agriPV) sites, where standard panels often suffer accelerated degradation.
Philadelphia Solar is a tier-1 (bankable) manufacturer operating since 2007, with automated production lines in Jordan, ensuring consistent module quality and supporting bank financing for projects.
The PS-M156(HCBF)-GG-xxxW series launched in 2021 and was discontinued in 2024 (superseded by newer series, including PS-MNB144/156). This means limited availability of identical modules for expanding existing installations and potentially longer lead times for warranty claims.
Module efficiency (20.7-21.06%) trails comparable 590 Wp modules built on newer N-type cells, e.g., Talesun TM7G72M (22.8%), Horay Solar HS 182-144 TC-D Ocean (22.8%), and AE Solar HORIZON CMD-144BDS (22.86%) - a gap of roughly 1.8-2.2 percentage points that translates into a larger required installation area for the same capacity.
- At 21.1% efficiency, this panel is on par with typical PERC 550-600W modules
- At 210.6 W/m² power density, roof space requirements are typical for PERC 550-600W panels
- Temperature coefficient of -0.35%/°C matches the PERC 550-600W median
- At 35.3 kg (4.5 kg above PERC 550-600W median of 30.8 kg), requires checking roof load capacity
- #9625 for efficiency, #10404 for temperature performance out of 14005 panels
