Fully robotized production lines ensure consistent batch quality, which supports financing for large EPC installations. - **25-year power warranty, -0.6%/year** - A 25-year linear power warranty with an annual degradation of only -0.6% is a solid, proven result for PERC technology, offering a predictable degradation profile comparable to other tier-1 manufacturers. ## Cons - **20-21% efficiency below peer group** - Module efficiency (20-21%) is noticeably lower than comparable products in the same power class: LEDVANCE 22.77%, Sunlike Solar 22.8%, Solitek 22.56%. The ~1.5-2 pp gap stems from using older PERC technology instead of N-type TOPCon, meaning more roof area is needed for the same power output. - **Shorter product warranty (12 years)** - The 12-year product warranty is shorter than the 2026 market standard for newer N-type TOPCon panels - e.g. Canadian Solar TOPHiKu6 offers 25 years, and Q CELLS Q.PEAK DUO/Q.TRON provide 25-year product coverage. This may reduce the series' competitiveness in EPC tenders requiring longer service coverage. - **No bifacial variant available** - The series is mono-facial only, while some peer comparables (Sunlike Solar SKT M10-108D6, likely LEDVANCE N54LB) are glass-glass bifacial modules offering an additional rear-side energy gain of several to over ten percent that this series cannot deliver. ## About this series The PS-M144(HC)-xxxW series comprises monocrystalline solar panels built with **half-cut** cell technology (144 cut PERC cells arranged in a 72x2 layout) combined with multi-busbar (MBB) interconnection, which together reduce internal resistance losses and improve current handling even when the module is not fully illuminated. By splitting cells in half, the panel handles partial shading more gracefully - a shaded half-cell causes a smaller power drop across the string compared to conventional full-size cell modules, translating into real energy gains in urban or industrial rooftop settings. The half-cut design also delivers **resistance to microcracks** superior to 5-busbar panels, along with more favorable temperature coefficients, which matters for installations on roofs exposed to intense sun. The series is backed by a **25-year linear power warranty** with an annual degradation rate of only -0.6%, making it an appealing choice both for investors in industrial-scale installations and for homeowners seeking predictable long-term returns. The panels are manufactured on fully robotic production lines, ensuring consistent quality and stable parameters across large batches, an important factor for large EPC projects. ## Notable figures - At 20.5% efficiency, this panel is on par with typical \*\*PERC 400-450W\*\* modules - At 204.7 W/m² power density, roof space requirements are typical for \*\*PERC 400-450W\*\* panels - At -0.30%/°C (vs median -0.35%/°C), loses ~2% less power in hot conditions - Weight of 24.0 kg is 2.0 kg above \*\*PERC 400-450W\*\* median (22.0 kg) - verify structural support - In the top 81% for efficiency among all PERC panels ## Questions ### What is the maximum power output of the Philadelphia Solar PS-M144(HC)-xxxW panel? The top model in the PS-M144(HC)-xxxW series reaches up to 455 Wp of maximum power. This high output is achieved through half-cut PERC technology with 144 cut cells and multi busbar (MBB) interconnection, which together reduce internal resistance losses and improve current output even under partial module illumination. ### What warranty comes with the Philadelphia Solar PS-M144(HC)-xxxW panels? The manufacturer provides a 12-year product warranty along with a 25-year linear power warranty, limiting annual performance degradation to just -0.6%. These are among the more favorable terms on the market, making the series a solid choice for both residential installations and larger commercial projects seeking predictable return on investment. ### Do half-cut PS-M144(HC) panels handle partial shading better than standard modules? Yes. Splitting the 144 PERC cells into halves in a 72x2 configuration means a single shaded cell causes a smaller power drop across the whole string compared to classic full-size panels. This helps the array perform better under partial shading from chimneys, antennas, or nearby buildings, resulting in higher energy yield in urban or industrial rooftop environments. ### Is Philadelphia Solar a tier 1 manufacturer, and where is it based? Yes, Philadelphia Solar holds tier 1 manufacturer status, confirming financial stability and bankability important for project financing. The company is headquartered in Jordan, and the PS-M144(HC)-xxxW series is produced on fully robotic manufacturing lines, ensuring consistent quality and stable parameters across the entire delivery batch. ### How does half-cut technology with MBB differ from standard 5-busbar panels? Cutting cells in half lowers the current flowing through each cell, reducing internal resistance losses and the risk of overheating. Combined with multi busbar (MBB) interconnection, the PS-M144(HC) series achieves better microcrack resistance and more favorable temperature coefficients than 5-busbar modules, which matters for installations on heavily sun-exposed roofs. ### Are the PS-M144(HC)-xxxW panels bifacial? No, the PS-M144(HC)-xxxW series consists of monofacial panels built on monocrystalline PERC cells. Despite lacking bifacial technology, high efficiency is achieved through the half-cut design and MBB interconnection, which minimize current losses and improve performance under uneven illumination. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/PS-m144HC450W-eaf80644d487.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +50 W, +4.3 pp, +5 yr warranty | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +45 W, +4.0 pp, +5 yr warranty | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +45 W, +4.0 pp, +5 yr warranty | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | Lighter, +3.8 pp, +5 yr warranty | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +40 W, +3.8 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-495M](https://comparepv.com/panel/longi-lr7-54hjd-495m) | 495 W | +50 W, cooler, +3.8 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +40 W, +3.8 pp, +5 yr warranty | | [Philadelphia Solar PS-M144(HC)-435W](https://comparepv.com/panel/philadelphia-solar-ps-m144-hc-435w) | 435 W | -10 W, -0.5 pp | | [Philadelphia Solar PS-M144(HC)-440W](https://comparepv.com/panel/philadelphia-solar-ps-m144-hc-440w) | 440 W | -0.3 pp | | [Philadelphia Solar PS-M144(HC)-450W](https://comparepv.com/panel/philadelphia-solar-ps-m144-hc-450w) | 450 W | Very close match | | [Philadelphia Solar PS-M144(HC)-455W](https://comparepv.com/panel/philadelphia-solar-ps-m144-hc-455w) | 455 W | +10 W, +0.5 pp | | [Gamko New Energy GKA120N-PRO-590W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-590w) | 590 W | +145 W, +3.3 pp, +5 yr warranty | | [Gamko New Energy GKA120N-PRO-585W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-585w) | 585 W | +140 W, +3.1 pp, +5 yr warranty | | [Bisol BGO 580](https://comparepv.com/panel/bisol-bgo-580) | 580 W | +135 W, +3.0 pp, +5 yr warranty | | [Gamko New Energy GKA120N-PRO-580W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-580w) | 580 W | +135 W, +2.9 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/philadelphia-solar-ps-m144-hc-445w Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
