Middle of its segment, modest efficiency
The Silk Nova All Black series is where FuturaSun pairs clean aesthetics with real-world energy performance, targeting system owners for whom the rooftop's look matters just as much as its output. The modules are built around monocrystalline n-type half-cut cells with multi busbar (MBB) technology, which reduces resistive losses, improves shading tolerance, and delivers more stable energy harvest throughout the day. The uniform all-black frame and black backsheet let the panel blend visually into virtually any roof type, without the bright accents that often undercut the look of conventional modules. Thanks to its high efficiency and improved low-light performance, the series works well both on space-constrained roofs and in less sun-rich climates. Another key advantage is its excellent power temperature coefficient, which means the panels lose less output on hot days than many competing products. The package is rounded out by a long-term product and performance warranty backed by the manufacturer's Italian headquarters, giving installers and investors confidence in low power degradation over decades of operation. It is a strong fit for anyone looking to balance design, durability, and a system's real LCOE.
Ranking
Signals from the data
Tight roof space, roofs where every square metre has to count and owners who want a long output guarantee.
Bottom 7% of the N-type 450-500 W segment, against a median of 22.52%. Ranked 7,581st in the whole database.
Bottom 7% of the N-type 450-500 W segment, against a median of 225.3. Ranked 7,578th in the whole database.
Bottom 8% of the N-type 450-500 W segment, against a median of 30 yrs. Ranked 10,001st in the whole database.
Monocrystalline n-type half-cut cells with multi busbar technology reduce resistive losses and improve partial-shading performance, delivering 21.7-22.16% efficiency with a more stable daily energy yield compared to older PERC cell designs.
The Pmax temperature coefficient of only -0.29%/°C compares favorably to typical PERC modules at around -0.35%/°C. Above the NOCT rating of 45°C, this translates into a measurably higher yield on hot days versus many competing designs.
A uniform black frame and black backsheet, with no visible light-colored elements, allow the panel to blend visually with most roof types - a key selling point in the residential/prosumer segment.
15 years of product warranty and 25 years of performance warranty (approx. 92% power retention at 20 years and 89% at 25 years per the degradation curve) are backed by an Italian manufacturer founded in 2008. The series, launched in 2023, remains in active production, ensuring service and spare-parts availability.
The maximum efficiency of 22.16% is marginally lower than comparable 480 Wp modules - the Sunket New Energy SKT460~480M10-120D3 and Shinson S-Blade BIPV Frameless both reach 22.24%. The gap is small (~0.08 pp), but this series is not the efficiency leader in the premium n-type segment.
Silk Nova All Black is a monofacial module, unlike the First Solar Series 6 Plus Bifacial in a similar power class (480 Wp). This means it lacks the additional yield from reflected irradiance, which can matter for ground-mount or high-albedo elevated installations.
- At 21.7% efficiency, this panel is 0.8pp below the N-type 450-500W median of 22.5%
- Power density of 217.0 W/m² is 8.3 W/m² below N-type 450-500W median (225.3 W/m²) - needs more roof space
- Temperature coefficient of -0.29%/°C matches the N-type 450-500W median
- At 22.4 kg, this panel is 1.3 kg lighter than N-type 450-500W median (23.7 kg) - easier handling during installation
- #7581 for efficiency, #2260 for temperature performance out of 14269 panels
