Bifacial light absorption captures additional rear-side energy, boosting yield per square meter without expanding the installation footprint. - **Reinforced mechanical construction** - 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. - **30-year linear power warranty** - 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. - **Resistance to harsh environmental conditions** - PID, salt mist, and ammonia resistance certifications allow deployment in coastal installations and agricultural (agriPV) sites, where standard panels often suffer accelerated degradation. - **Tier-1 manufacturer since 2007, robotic production** - 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. ## Cons - **Series discontinued** - The PS-M156(HCBF)-GG-xxxW series launched in 2021 and was discontinued in 2024 (superseded by newer series, including PS-MNB144/156).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. - **Efficiency below current market benchmarks** - 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. ## About this series 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. ## Notable figures - Efficiency of 20.9% matches the \*\*PERC 550-600W\*\* median - At 208.8 W/m², this panel generates 4.1 W/m² less per unit area than \*\*PERC 550-600W\*\* median (212.9 W/m²) - Temperature coefficient of -0.35%/°C matches the \*\*PERC 550-600W\*\* median - At 35.3 kg, this panel is 4.5 kg heavier than the \*\*PERC 550-600W\*\* median (30.8 kg) - more demanding for installation crews - Ranked #10320 out of 14005 panels for efficiency in the database ## Questions ### Is the PS-M156(HCBF)-GG-xxxW series by Philadelphia Solar still available for purchase? The PS-M156(HCBF)-GG-xxxW series has been discontinued from active production and replaced by newer models in Philadelphia Solar's lineup. Availability is now limited to remaining distributor stock. Anyone expanding an existing installation built on this series should act quickly or consider replacement modules with similar power output and dimensions. ### How does bifacial technology in the PS-M156(HCBF)-GG-xxxW panels differ from standard monofacial panels? A bifacial panel captures energy not only through its front side but also through the rear side, using light reflected off the ground, roof, or snow. For the PS-M156(HCBF)-GG-xxxW series, this results in additional energy yield without increasing the installation's footprint, which is especially beneficial for ground-mounted solar farms with light-colored surfaces. ### What warranty comes with the Philadelphia Solar PS-M156(HCBF)-GG-xxxW series? The manufacturer offers a 12-year product warranty along with a 30-year linear power output warranty. This means the panel is expected to maintain its guaranteed performance level even after three decades of use, reflecting the low annual degradation of the half-cut PERC cells used in this series. ### Can the PS-M156(HCBF)-GG-xxxW panels withstand heavy snow loads and strong wind? Yes, thanks to the AL 6063-T5/6005-T6 aluminum frame and dual-glass construction, the module withstands a front load of up to 5400 Pa and a rear load of up to 2400 Pa. These ratings allow for safe installation in regions with heavy snowfall and strong winds, such as on farm and industrial rooftops. ### What benefits do half-cut cells and 10 busbars provide in the PS-M156(HCBF)-GG-xxxW panel? The 182 mm half-cut cells are split in half, reducing current losses and limiting the impact of partial shading and microcracks on overall module performance. The 10-busbar layout further lowers internal resistance and improves current collection, together delivering higher efficiency and better temperature coefficients compared to full-cell panels. ### Are the PS-M156(HCBF)-GG-xxxW panels suitable for coastal installations or agricultural areas? Yes, the series is certified for resistance to PID, salt mist, and ammonia exposure, making it a suitable choice for coastal installations exposed to salt corrosion as well as for solar farms in agricultural areas where ammonia fumes from livestock operations are present in the air. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/M156HCBF-GG-xxxW-580-590W-with-ou-t1-87f355293e98.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +3.9 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +3.7 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | Cooler, lighter, +3.7 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +45 W, cooler, +3.5 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, 19 kg lighter, +3.5 pp | | [Philadelphia Solar PS-M156(HCBF)-GG-580W](https://comparepv.com/panel/philadelphia-solar-ps-m156-hcbf-gg-580w) | 580 W | Very close match | | [Philadelphia Solar PS-M156(HCBF)-GG-590W](https://comparepv.com/panel/philadelphia-solar-ps-m156-hcbf-gg-590w) | 590 W | Very close match | | [Philadelphia Solar PS-MNB156(HCBF)-630W](https://comparepv.com/panel/philadelphia-solar-ps-mnb156-hcbf-630w) | 630 W | +45 W, cooler, +1.7 pp | | [Philadelphia Solar PS-MNB156(HCBF)-635W](https://comparepv.com/panel/philadelphia-solar-ps-mnb156-hcbf-635w) | 635 W | +50 W, cooler, +1.9 pp | | [Philadelphia Solar PS-MNB156(HCBF)-640W](https://comparepv.com/panel/philadelphia-solar-ps-mnb156-hcbf-640w) | 640 W | +55 W, cooler, +2.0 pp | | [Philadelphia Solar PS-MNB156(HCBF)-645W](https://comparepv.com/panel/philadelphia-solar-ps-mnb156-hcbf-645w) | 645 W | +60 W, cooler, +2.2 pp | | [Philadelphia Solar PS-MNB156(HCBF)-650W](https://comparepv.com/panel/philadelphia-solar-ps-mnb156-hcbf-650w) | 650 W | +65 W, cooler, +2.4 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +95 W, cooler, +4.3 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +90 W, cooler, +4.1 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +115 W, cooler, +4.1 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +110 W, cooler, +4.0 pp | --- Source: https://comparepv.com/panel/philadelphia-solar-ps-m156-hcbf-gg-585w Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
