Strong in heat, no clear weak spot
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.
Ranking
Signals from the data
Residential and commercial.
Top 3% of the PERC 400-450 W segment, against a median of -0.350. Ranked 6,093rd in the whole database.
Philadelphia Solar backs the series with a full 25-year product warranty alongside the 25-year power warranty, while the typical market standard is only 10-12 years of product coverage against a 25-year power warranty. The low annual degradation rate of just -0.55% ensures predictable energy yield over the panel's lifetime.
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.
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.
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.
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.
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.
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.
- At 20.5% efficiency, this panel is on par with typical PERC 400-450W modules
- At 205.1 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
- At 20.5 kg, this panel is 1.5 kg lighter than PERC 400-450W median (22.0 kg) - easier handling during installation
- Ranked #11308 out of 14005 panels for efficiency in the database
