The low annual degradation rate of just -0.55% ensures predictable energy yield over the panel's lifetime. - **Half-cut cells with 10 busbars** - Splitting PERC cells into halves and using 10 busbars (versus the conventional 5BB) reduces microcrack risk during transport and installation and improves low-light behavior, resulting in more stable energy production under partial shading conditions. - **Tier-1 manufacturer with 19-year track record** - Philadelphia Solar, founded in 2007 in Jordan, is listed on BloombergNEF's Tier-1 bankable manufacturer list (Q2 2026), which facilitates commercial bank financing and boosts confidence among institutional investors. - **High PID resistance** - Enhanced resistance to potential-induced degradation (PID) minimizes long-term power loss risk, which matters for large rooftop and ground-mount installations operating under continuous system voltage. - **Full-black aesthetic for residential roofs** - The anodized aluminum black frame and uniform black front blend visually with roof coverings, a significant selling point for private investors concerned with facade aesthetics. ## Cons - **Efficiency trails N-type leaders** - The 20.5-21% efficiency based on Mono PERC technology falls short of the best comparable N-type TOPCon models in this power class, e.g., Luxor Solar Eco Line (410W, 21.33%), reflecting PERC's inherent efficiency ceiling versus newer N-type cells. - **No bifacial variant in this series** - Black Iris Mono is a monofacial module (is\_bifacial: false), while comparable peer Luxor Solar offers a glass-glass bifacial version in the same 410W power class, delivering additional albedo-driven energy yield unavailable in this series. ## About this series Black Iris Mono is a series that pairs an all-black aesthetic with construction engineered for residential rooftops. The use of **half-cut** cells in **Mono PERC** technology with 10 busbars reduces the risk of microcracks and power loss that occur more frequently in conventional 5BB modules during transport or installation. Splitting the cells in half also gives the panel more favorable temperature coefficients, translating into steadier energy output on hot days when standard modules lose efficiency. The black anodized aluminum frame combined with a uniform black front lets the array blend visually with the roof, an important advantage for homeowners who care about the look of their facade. The series also stands out for its **high resistance to potential-induced degradation (PID)**, ensuring predictable energy yield throughout its service life. The module's low weight simplifies installation on structures with limited load capacity, while its **mechanical strength** allows reliable operation under demanding snow and wind loads. The manufacturer backs the series with a **25-year linear power warranty** and an annual degradation rate of just -0.55%, making Black Iris Mono a dependable choice for both residential and commercial installations. ## Notable figures - At 20.8% efficiency, this panel is on par with typical \*\*PERC 400-450W\*\* modules - At 207.7 W/m² power density, roof space requirements are typical for \*\*PERC 400-450W\*\* panels - Temperature coefficient of -0.30%/°C vs median -0.35%/°C means ~2% less power loss at 65°C - At 20.5 kg, this panel is 1.5 kg lighter than \*\*PERC 400-450W\*\* median (22.0 kg) - easier handling during installation - #10457 for efficiency, #6093 for temperature performance out of 14005 panels ## Questions ### What is the maximum power output of the Black Iris Mono panel and is it enough to power a single-family home? Black Iris Mono series panels reach a maximum power output of 410 Wp. An installation of about 15-20 modules (roughly 6-8 kWp) covers the typical energy demand of a 100-150 m2 single-family home, depending on electricity usage and location. ### Are Black Iris Mono panels suitable for a pitched residential roof? Yes, the series is specifically designed for residential roofs. The module's low weight makes installation easier on rafters with limited load capacity, and the uniform black front with an anodized black frame blends visually with the roof covering, which matters to investors focused on facade aesthetics. ### How do half-cut cells with 10 busbars differ from classic 5BB panels? Splitting cells in half (half-cut) using Mono PERC technology with 10 busbars significantly reduces the risk of microcracks during transport and installation compared to classic 5BB modules. This design also improves temperature coefficients, so the panel loses less power on hot days than older-generation modules. ### What warranty comes with Black Iris Mono panels and what is the annual power degradation rate? Philadelphia Solar backs the Black Iris Mono series with a 25-year linear power warranty and a 25-year product warranty. Annual output degradation is only -0.55%, ensuring predictable and high energy yield throughout the entire lifespan of the installation. ### Are Black Iris Mono panels resistant to PID degradation and harsh weather conditions? Yes, the series features high resistance to potential induced degradation (PID), preventing unexpected power loss over time. The reinforced mechanical construction allows the modules to operate safely under heavy snow load and strong wind conditions. ### Who manufactures the Black Iris Mono panels and is it a Tier 1 producer? The Black Iris Mono series is manufactured by Philadelphia Solar, headquartered in Jordan and classified as a Tier 1 manufacturer, indicating strong financial stability and bankability. The panels are non-bifacial, generating power only from the front side of the module. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/PS-IRIS-M108-400-410W-27b33a9aee6d.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-455-MAH54Db](https://comparepv.com/panel/aiko-aiko-455-mah54db) | 455 W | +50 W, +2.5 pp, +5 yr warranty | | [Longi Solar LR5-54HTH-455M](https://comparepv.com/panel/longi-lr5-54hth-455m) | 455 W | +50 W, cooler, +2.5 pp | | [Yingli YL455CF54 e/2](https://comparepv.com/panel/yingli-yl455cf54-e-2) | 455 W | +50 W, +2.5 pp, +5 yr warranty | | [Einnova Solarline ESM-455T](https://comparepv.com/panel/einnova-solarline-esm-455t) | 455 W | +50 W, +2.5 pp, +5 yr warranty | | [SunEvo Solar SE5-54HBC-455W](https://comparepv.com/panel/sunevo-solar-se5-54hbc-455w) | 455 W | +50 W, cooler, +2.5 pp | | [Just Solar JST-EDMH-(445-465)W-TD (455W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-455w-class) | 455 W | +50 W, +2.5 pp, +5 yr warranty | | [Luxor Solar LX-455M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-455m-182r-96-gg) | 455 W | +50 W, +2.5 pp, +5 yr warranty | | [Philadelphia Solar PS-M108(HC)-400W](https://comparepv.com/panel/philadelphia-solar-ps-m108-hc-400w) | 400 W | -0.3 pp | | [Philadelphia Solar PS-M108(HC)-410W](https://comparepv.com/panel/philadelphia-solar-ps-m108-hc-410w) | 410 W | Very close match | | [Philadelphia Solar PS-MNB108(HCBF)-425W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-425w) | 425 W | +20 W, +1.0 pp, +5 yr warranty | | [Philadelphia Solar PS-MNB108(HCBF)-430W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-430w) | 430 W | +25 W, +1.2 pp, +5 yr warranty | | [Philadelphia Solar PS-MNB108(HCBF)-435W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-435w) | 435 W | +30 W, +1.5 pp, +5 yr warranty | | [Philadelphia Solar PS-MNB108(HCBF)-440W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-440w) | 440 W | +35 W, +1.8 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +105 W, cooler, +4.2 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +90 W, +4.0 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +100 W, cooler, +3.9 pp | --- Source: https://comparepv.com/panel/philadelphia-solar-ps-m108-hc-405w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
