N-type cells also typically show lower LID/LeTID degradation than PERC. - **Moderate bifaciality ratio** - The bifaciality ratio is 65±5% per manufacturer data, a moderate figure compared to premium glass-glass bifacial modules reaching 70-85%, limiting the additional energy yield captured from ground-reflected irradiance. ## About this series The Dark PHENex Bifacial series is built for installers and investors looking for panels that combine sleek aesthetics with real energy performance. The modules use **half-cut cell technology** along with a dense busbar grid, reducing shading losses and improving resistance to microcracks. The distinctive, fully black frame and cell backing let the panel blend seamlessly with any roof type without sacrificing output - a solid fit for customers who care as much about the look of their installation as its efficiency. The defining feature of the series is **dual-sided bifacial technology**, which captures reflected light on the rear side of the module, boosting overall energy yield without increasing the footprint. The panels are **PID-resistant**, ensuring stable performance throughout their service life. The design works well on both pitched roofs and ground-mounted installations, supporting on-grid and off-grid systems, including commercial projects. The series comes with a **25-year product and performance warranty**, making it a safe long-term choice for installers seeking a proven, aesthetic, and high-performing photovoltaic solution. ## Notable figures - At 21.0% efficiency, this panel is on par with typical \*\*PERC 400-450W\*\* modules - 210.3 W/m² power density - 4.1 W/m² more than \*\*PERC 400-450W\*\* median (206.2 W/m²), more power per roof area - Temperature coefficient of -0.35%/°C matches the \*\*PERC 400-450W\*\* median - Weight of 20.5 kg (1.5 kg below \*\*PERC 400-450W\*\* median of 22.0 kg) allows easier transport and roof mounting - Bifacial design (65% factor) captures reflected light - adds 3-10% yield on ground-mount or white roof ## Questions ### How does bifacial technology in Philadelphia Solar Dark PHENex panels differ from standard monofacial modules? Dark PHENex Bifacial panels capture sunlight on both sides of the module - directly on the front and via reflected light on the rear, bouncing off the roof, ground, or a light-colored surface beneath the array. This allows a higher annual energy yield from the same roof area compared to a classic monofacial panel, without increasing the number of modules in the installation. ### What warranty comes with Philadelphia Solar Dark PHENex Bifacial panels? The Dark PHENex Bifacial series comes with a 25-year product warranty and a 25-year performance warranty. This means the manufacturer covers not only factory defects but also guarantees a defined power output level throughout the panel's 25-year service life, which is standard among leading tier 1 manufacturers. ### Are Dark PHENex panels suitable for a pitched roof, or only ground-mount installations? The Dark PHENex Bifacial design works well on both pitched roofs and ground-mount systems. The all-black frame and cell background blend harmoniously with residential roofs, while the half-cut cell structure improves shading tolerance around chimneys or dormers. The panel also supports on-grid, off-grid, and commercial installations. ### What is PERC cell technology in Philadelphia Solar panels and how does it affect power output? PERC (Passivated Emitter and Rear Cell) adds a passivation layer to the back of the cell that reflects unused photons back into the cell, boosting conversion efficiency. Combined with bifacial and half-cut technology, this allows the Dark PHENex panel to reach a maximum power output of up to 410 Wp while maintaining strong long-term stability. ### Are Dark PHENex Bifacial panels resistant to PID degradation? Yes, this series is resistant to PID (Potential Induced Degradation), a phenomenon that causes power loss due to voltage differences between the cells and the grounded frame or mounting structure. This resistance keeps the panel's energy output stable throughout its service life, even in large arrays with high system voltage. ### Who manufactures Dark PHENex Bifacial panels, and are they a tier 1 supplier? Dark PHENex Bifacial panels are manufactured by Philadelphia Solar, headquartered in Jordan and classified as a tier 1 manufacturer under the BloombergNEF ranking. Tier 1 status reflects financial stability and bankability, which matters when financing an installation through a loan or lease and for long-term warranty servicing. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Dark-phenex-400w-2024-6767a6119c14.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A460-MAH54Mb](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a460-mah54mb-1) | 460 W | +50 W, cooler, +2.6 pp | | [Just Solar JST-EDMH-(445-465)W-TD (460W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-460w-class) | 460 W | +50 W, +2.6 pp, +5 yr warranty | | [Luxor Solar LX-460M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-460m-182r-96-gg) | 460 W | +50 W, cooler, +2.6 pp | | [Philadelphia Solar PS-MNB108(HCBF)-460W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-460w) | 460 W | +50 W, cooler, +2.5 pp | | [JA Solar JAT54S40-460/LR](https://comparepv.com/panel/ja-solar-jat54s40-460-lr) | 460 W | +50 W, cooler, +2.5 pp | | [Luxor Solar LX-460M/182R188-108+ GG](https://comparepv.com/panel/luxor-solar-lx-460m-182r188-108-gg) | 460 W | +50 W, cooler, +2.4 pp | | [AIKO AIKO-455-MAH54Db](https://comparepv.com/panel/aiko-aiko-455-mah54db) | 455 W | Cooler, +2.3 pp, +5 yr warranty | | [Longi Solar LR5-54HTH-455M](https://comparepv.com/panel/longi-lr5-54hth-455m) | 455 W | +45 W, cooler, +2.3 pp | | [Philadelphia Solar PS-M108(HC)-400W](https://comparepv.com/panel/philadelphia-solar-ps-m108-hc-400w) | 400 W | -10 W, cooler, -0.5 pp | | [Philadelphia Solar PS-M108(HC)-405W](https://comparepv.com/panel/philadelphia-solar-ps-m108-hc-405w) | 405 W | Cooler | | [Philadelphia Solar PS-MNB108(HCBF)-425W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-425w) | 425 W | Cooler, +0.8 pp, +5 yr warranty | | [Philadelphia Solar PS-MNB108(HCBF)-430W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-430w) | 430 W | Cooler, +1.1 pp, +5 yr warranty | | [Philadelphia Solar PS-MNB108(HCBF)-435W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-435w) | 435 W | Cooler, +1.3 pp, +5 yr warranty | | [Philadelphia Solar PS-MNB108(HCBF)-440W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-440w) | 440 W | Cooler, +1.6 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +100 W, cooler, +4.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +85 W, cooler, +3.8 pp | --- Source: https://comparepv.com/panel/philadelphia-solar-ps-m108-hcbf-410w 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.
