**Bifacial gain of 7-25%** - 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 on par with segment leaders** - 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. - **Dual glass instead of rear backsheet** - 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. - **30-year power warranty** - 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. - **Established Tier-1 manufacturer standing** - 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. ## Cons - **Production discontinued (2023)** - 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 technology instead of TOPCon/HJT** - 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. ## About this series 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**. ## Notable figures - At 21.3% efficiency, this panel is on par with typical \*\*PERC 550-600W\*\* modules - Power density of 212.9 W/m² matches the \*\*PERC 550-600W\*\* median - At -0.35%/°C, hot weather performance is typical for \*\*PERC 550-600W\*\* panels - At 32.5 kg, this panel is 1.7 kg heavier than the \*\*PERC 550-600W\*\* median (30.8 kg) - more demanding for installation crews - Bifacial design (65% factor) captures reflected light - adds 3-10% yield on ground-mount or white roof ## Questions ### Is the PHENex PS-M144(HCBF)-GG series still available for purchase? The PHENex PS-M144(HCBF)-GG series has been discontinued by Philadelphia Solar and is no longer in active production. Units may still be available through distributors as remaining stock, but for larger installations it's best to confirm current availability with your supplier and consider the manufacturer's current bifacial models as an alternative. ### What does bifacial technology add to the PHENex PS-M144(HCBF)-GG panels? Thanks to the dual tempered glass construction replacing the standard backsheet, the rear side of the module captures light reflected off the ground. On gravel roofs, light-colored surfaces, snow, or near water, this can add several to over ten percent extra yield above the 550 Wp rated power, improving payback for commercial and industrial installations. ### What warranty comes with the PHENex PS-M144(HCBF)-GG panels? Philadelphia Solar provides a 12-year product warranty and a 30-year linear power output warranty. The manufacturer holds Tier 1 status, which adds confidence in warranty support, though given the series' discontinued status it's worth confirming service terms directly with your distributor before purchase. ### How do PERC half-cut cells differ from standard full-size cells? The module uses 144 monocrystalline PERC half-cut cells, essentially standard cells cut in half. This design reduces resistive losses and limits power drop under partial shading, such as from leaves or chimneys, resulting in more stable energy production compared to panels with full-size cells. ### Are the PHENex PS-M144(HCBF)-GG panels suitable for large-scale solar farms? Yes, the series was designed for commercial and industrial installations. Power output up to 550 Wp per module, a rugged anodized aluminum frame rated for high wind and snow loads, and bifacial technology make these panels well suited for both large ground-mounted farms and demanding industrial rooftops. ### Does the dual-glass design of the PHENex PS-M144(HCBF)-GG affect durability and degradation? Yes, using dual tempered glass instead of a rear backsheet significantly improves the module's mechanical and chemical resistance. This design limits LID and PID degradation and extends panel lifespan compared to traditional backsheet construction, contributing to a lower cost of energy per installed watt over the system's lifetime. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/PS-m144-535-550-AR-copy-8a71e8999a78.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +3.7 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +3.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +3.4 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | Cooler, lighter, +3.4 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +3.3 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +3.2 pp | | [Philadelphia Solar PS-M144(HCBF)-GG-535W](https://comparepv.com/panel/philadelphia-solar-ps-m144-hcbf-gg-535w) | 535 W | -15 W, -0.6 pp | | [Philadelphia Solar PS-M144(HCBF)-GG-540W](https://comparepv.com/panel/philadelphia-solar-ps-m144-hcbf-gg-540w) | 540 W | -10 W, -0.4 pp | | [Philadelphia Solar PS-M144(HCBF)-540W](https://comparepv.com/panel/philadelphia-solar-ps-m144-hcbf-540w) | 540 W | Lighter, -0.4 pp, -5 yr warranty | | [Philadelphia Solar PS-M144(HCBF)-GG-545W](https://comparepv.com/panel/philadelphia-solar-ps-m144-hcbf-gg-545w) | 545 W | Very close match | | [Philadelphia Solar PS-M144(HCBF)-545W](https://comparepv.com/panel/philadelphia-solar-ps-m144-hcbf-545w) | 545 W | Lighter, -5 yr warranty | | [Philadelphia Solar PS-M144(HCBF)-550W](https://comparepv.com/panel/philadelphia-solar-ps-m144-hcbf-550w) | 550 W | Lighter, -5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +100 W, cooler, +3.9 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +95 W, cooler, +3.7 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +90 W, cooler, +3.5 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +85 W, cooler, +3.3 pp | --- Source: https://comparepv.com/panel/philadelphia-solar-ps-m144-hcbf-gg-550w Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
