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 - Efficiency of 20.7% matches the \*\*PERC 500-550W\*\* median - At 207.1 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 - At 32.5 kg (4.1 kg above \*\*PERC 500-550W\*\* median of 28.4 kg), requires checking roof load capacity - 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, +4.3 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +4.1 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +4.1 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +4.0 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +3.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +3.8 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +3.8 pp | | [Philadelphia Solar PS-M144(HCBF)-GG-540W](https://comparepv.com/panel/philadelphia-solar-ps-m144-hcbf-gg-540w) | 540 W | Very close match | | [Philadelphia Solar PS-M144(HCBF)-540W](https://comparepv.com/panel/philadelphia-solar-ps-m144-hcbf-540w) | 540 W | Lighter, -5 yr warranty | | [Philadelphia Solar PS-M144(HCBF)-GG-545W](https://comparepv.com/panel/philadelphia-solar-ps-m144-hcbf-gg-545w) | 545 W | +10 W, +0.4 pp | | [Philadelphia Solar PS-M144(HCBF)-545W](https://comparepv.com/panel/philadelphia-solar-ps-m144-hcbf-545w) | 545 W | Lighter, +0.4 pp, -5 yr warranty | | [Philadelphia Solar PS-M144(HCBF)-550W](https://comparepv.com/panel/philadelphia-solar-ps-m144-hcbf-550w) | 550 W | Lighter, +0.6 pp, -5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +115 W, cooler, +4.5 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +110 W, cooler, +4.3 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +105 W, cooler, +4.1 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +100 W, cooler, +3.9 pp | --- Source: https://comparepv.com/panel/philadelphia-solar-ps-m144-hcbf-gg-535w 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.
