The Silfab SIL NX series is a premium PV module line built around mono-PERC cells with a 5-busbar configuration, engineered for installations where both output and appearance matter. It stands out with a sleek all-black design - black anodized frame paired with a black backsheet lets the panels blend seamlessly with nearly any roof, making it a natural fit for high-profile residential and commercial projects where aesthetics carry as much weight as performance. Advanced cell technology delivers PID resistance, reducing the risk of voltage-induced power loss under demanding operating conditions and supporting more stable energy yield over the module's lifetime. The lightweight yet rugged frame has been load-tested to withstand extreme wind and snow conditions, making it suitable for both pitched-roof and ground-mount arrays with high mechanical demands. Modules are manufactured in automated, certified North American facilities under strict quality control. The series is backed by an industry-leading 25-year product warranty and 30-year linear power warranty, giving installers and investors confidence in predictable, long-term system performance and a secure investment for decades to come.

Common questions

6 answered
Are Silfab SIL NX 360W solar panels still available for purchase?
The SIL NX 360W series has been discontinued and is no longer part of Silfab's current production lineup. Some distributors may still hold leftover stock, but for new projects it's best to ask about the current equivalent model in the manufacturer's active range. Warranties issued on previously purchased modules remain fully valid regardless of the discontinuation.
What warranty comes with Silfab SIL NX solar panels?
SIL NX modules come with a 25-year product warranty covering material and workmanship defects, plus a 30-year linear power warranty guaranteeing sustained performance throughout the module's lifetime. This is one of the longer warranty periods on the market, making the installation a predictable investment even after this specific model's production has ended.
Is the Silfab SIL 360-NX panel suitable for a pitched residential roof?
Yes, the panel's dimensions of approximately 183×100 cm and weight of around 20 kg make it well-suited for typical pitched roofs on single-family homes. Its sleek all-black design - black anodized frame and black backsheet - blends into most roofing materials, which matters for installations where the system's appearance is as important to the homeowner as its performance.
What does mono-PERC technology with 5-busbar cells mean for the SIL NX panel?
Mono-PERC refers to monocrystalline cells with an added passivation layer on the rear surface that boosts sunlight-to-energy conversion efficiency. The 5-busbar cell structure adds more current-collecting pathways across each cell, improving conductivity and reducing resistive losses compared to older 3- or 4-busbar designs, resulting in more stable module output.
Are SIL NX panels resistant to PID degradation?
Yes, the cells used in the SIL NX series are engineered to resist potential-induced degradation (PID), a phenomenon that causes power loss due to voltage differences between the cell and the module frame. This helps the array maintain more consistent energy output over the long term, even under demanding operating conditions such as high humidity or elevated system voltages.
Where are Silfab SIL NX panels manufactured, and does it affect quality?
SIL NX panels are produced in Silfab's automated, certified manufacturing facilities in North America, with the company headquartered in Canada and holding Tier 1 supplier status. North American production under strict quality standards, along with BAA/ARRA compliance, made these modules a common choice for projects requiring North American-made components, such as U.S. public-sector programs.
