The n-type cell architecture combined with advanced passivation delivers **higher efficiency in low-light conditions** and more stable performance at elevated temperatures, translating into real-world energy gains rather than just improved STC lab figures. A half-cut cell layout with multi-busbar interconnection reduces resistive losses and improves **partial shading tolerance**, a key advantage on irregularly shaped roofs or sites near neighboring structures. With a lower long-term degradation rate, this series stands apart from conventional PERC modules, giving investors a better energy balance over the lifetime of the system. The panels are manufactured in the United States, which for many buyers means easier qualification for incentive programs and a shorter supply chain. The entire line is backed by a **25-year product warranty and a 30-year linear performance warranty**, making it a dependable choice for installers and investors seeking predictable returns on rooftop and ground-mount commercial-scale projects. ## Notable figures - Efficiency of 22.3% matches the \*\*N-type 500-550W\*\* median - Power density of 223.0 W/m² matches the \*\*N-type 500-550W\*\* median - Temperature coefficient of -0.29%/°C matches the \*\*N-type 500-550W\*\* median - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof - In the top 36% for efficiency among all N-type panels ## Questions ### How does N-type TOPCon cell technology in Silfab Commercial NTC panels differ from conventional PERC cells? N-type cells with a TOPCon passivation layer have a lower degradation rate and are less sensitive to boron-oxygen light-induced degradation than PERC cells. This lets Silfab Commercial NTC panels achieve higher efficiency in low-light conditions and more stable performance on hot days, translating into higher annual energy yield compared to comparable PERC-based modules. ### What warranty comes with Silfab Commercial NTC panels, and what does it cover? The Silfab Commercial NTC series carries a 25-year product warranty and a 30-year linear power warranty. The product warranty covers material and manufacturing defects, while the power warranty guarantees a set minimum percentage of the original rated output after 30 years, making this series one of the longer-warrantied options in the commercial module market. ### What is the maximum power output of a single Silfab Commercial NTC panel? Panels in the Silfab Commercial NTC series reach up to 570 Wp while keeping dimensions typical for the commercial segment. Higher per-panel output means fewer modules are needed to hit a target system capacity, lowering racking, cabling, and installation labor costs on large rooftop and ground-mount projects. ### Do Silfab Commercial NTC panels perform well on roofs with partial shading, such as from chimneys or nearby buildings? Yes. The half-cut cell design combined with a multi-busbar layout reduces resistive losses and improves the module's tolerance to partial shading. In practice, shading part of the panel from a chimney, antenna, or adjacent building causes a smaller drop in energy output than in traditional full-cell modules without cell segmentation. ### Are Silfab Commercial NTC panels manufactured in the United States? Yes, Silfab Commercial NTC modules are produced at Silfab's manufacturing facility in the United States. For investors, this typically means easier qualification for US incentive programs requiring domestic content, along with a shorter, more disruption-resistant supply chain compared to panels imported from Asia. ### How does Silfab Commercial NTC differ from the manufacturer's earlier PERC modules? The main difference is the use of N-type cells with TOPCon passivation instead of P-type PERC cells. This results in slower power degradation over time, higher efficiency in low light, and better resistance to high operating temperatures. As a result, the NTC series delivers higher cumulative energy yield over a system's lifetime than older PERC lines. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Silfab-SIL-530-XM-Bifacial-Data-Final-79366677ec63.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +2.7 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | -35 W, lighter, +2.5 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +30 W, cooler, +2.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +2.4 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +25 W, cooler, +2.3 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | -40 W, lighter, +2.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | -30 W, cooler, +2.2 pp | | [Silfab SIL-500 HM](https://comparepv.com/panel/silfab-sil-500-hm) | 500 W | -30 W, hotter, -1.3 pp | | [Silfab SIL-520 XM BIFACIAL](https://comparepv.com/panel/silfab-sil-520-xm-bifacial) | 520 W | -10 W, -0.4 pp | | [Silfab SIL-540-XM-BIFACIAL](https://comparepv.com/panel/silfab-sil-540-xm-bifacial) | 540 W | +10 W, +0.4 pp | | [Gamko New Energy GKA120N-PRO-590W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-590w) | 590 W | +60 W, hotter, +1.5 pp | | [Gamko New Energy GKA120N-PRO-585W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-585w) | 585 W | +55 W, hotter, +1.3 pp | | [Bisol BGO 580](https://comparepv.com/panel/bisol-bgo-580) | 580 W | +50 W, +1.2 pp | | [Gamko New Energy GKA120N-PRO-580W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-580w) | 580 W | +50 W, hotter, +1.1 pp | --- Source: https://comparepv.com/panel/silfab-sil-530-xm Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
