The panels use **half-cut monocrystalline cells**, which significantly reduce power losses under partial shading compared to conventional modules, keeping energy output stable even in less favorable sunlight conditions. The Prime NTC version is built on **N-Type TOPCon technology**, which limits cell degradation over time and improves performance in high temperatures and low-light conditions, translating into real gains in annual energy production. The distinctive, **elegant triple black design** blends well with modern architecture, keeping rooflines and facades visually clean. The frame construction has been reinforced for mechanical resilience, allowing the panels to withstand heavy snow and wind loads, making the series well suited to demanding climate conditions. Manufacturing takes place in North America, ensuring consistent quality control and a shorter supply chain. The manufacturer backs the panels with a long product warranty and a linear power performance warranty, giving system owners confidence in the long-term profitability of their investment. ## Notable figures - At 20.7% efficiency, this panel is on par with typical \*\*PERC 400-450W\*\* modules - At 206.8 W/m² power density, roof space requirements are typical for \*\*PERC 400-450W\*\* panels - At -0.36%/°C, hot weather performance is typical for \*\*PERC 400-450W\*\* panels - Ranked #10764 out of 14005 panels for efficiency in the database ## Questions ### What are half-cut cells in Silfab Prime panels and what's the benefit? Silfab Prime panels use 132 half-cut monocrystalline cells, meaning each cell is split into two smaller segments. This design significantly reduces voltage drops and power losses caused by partial shading, such as from a chimney, antenna, or fallen leaves, compared to panels with full-size cells. In practice, this results in more stable daily energy production even when part of the roof is periodically shaded. ### What warranty comes with Silfab Prime panels? Silfab Prime panels come with a 25-year product warranty and a 30-year linear power warranty, guaranteeing a gradually declining but predictable performance level over the entire period. This is one of the longer warranties available for residential solar panels, giving homeowners strong assurance about the long-term return on their investment. ### Is Silfab Prime suitable for roofs exposed to heavy snow loads or strong wind? Yes, the Silfab Prime frame is reinforced for mechanical durability and certified under IEC and UL standards, which include load-resistance testing. The panel withstands high snow loads and strong wind, making the series well suited to demanding climate conditions, similar to those found in many regions during winter. ### What's the difference between Silfab Prime and the Silfab Prime NTC version? The standard Silfab Prime is built on proven PERC cell technology, while the Prime NTC version uses newer N-Type TOPCon technology. TOPCon reduces cell degradation over time and improves performance at high temperatures and in low-light conditions, translating into higher annual energy yield. Prime NTC is the option for buyers seeking slightly higher efficiency at a higher price point. ### Is Silfab Prime a bifacial (dual-sided) solar panel? No, Silfab Prime is a monofacial panel with a maximum power output of up to 410 Wp, optimized for standard installation on a sloped residential roof. Unlike bifacial panels, it doesn't generate additional energy from the rear side of the module, making it a sufficient and more cost-effective solution for typical rooftop installations mounted close to the roof surface. ### Is Silfab a Tier 1 manufacturer, and where are Prime panels made? Yes, Silfab is a Tier 1 manufacturer, reflecting its financial stability and long-standing industry experience. All Prime panel production takes place in North America, with the company headquartered in Canada. This ensures high manufacturing consistency, tighter quality control, and a shorter, more predictable supply chain compared to panels imported from distant markets. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Silfab-SIL-410-HC-Data-Final-8a2ab343d040.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A460-MAH54Mb](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a460-mah54mb-1) | 460 W | +50 W, cooler, +2.9 pp | | [Just Solar JST-EDMH-(445-465)W-TD (460W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-460w-class) | 460 W | +50 W, cooler, +2.9 pp | | [Luxor Solar LX-460M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-460m-182r-96-gg) | 460 W | +50 W, cooler, +2.9 pp | | [Philadelphia Solar PS-MNB108(HCBF)-460W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-460w) | 460 W | +50 W, cooler, +2.8 pp | | [JA Solar JAT54S40-460/LR](https://comparepv.com/panel/ja-solar-jat54s40-460-lr) | 460 W | +50 W, cooler, +2.8 pp | | [Luxor Solar LX-460M/182R188-108+ GG](https://comparepv.com/panel/luxor-solar-lx-460m-182r188-108-gg) | 460 W | +50 W, cooler, +2.7 pp | | [AIKO AIKO-455-MAH54Db](https://comparepv.com/panel/aiko-aiko-455-mah54db) | 455 W | +45 W, cooler, +2.6 pp | | [Longi Solar LR5-54HTH-455M](https://comparepv.com/panel/longi-lr5-54hth-455m) | 455 W | Cooler, +2.6 pp, -5 yr warranty | | [Silfab SIL-400 HC+](https://comparepv.com/panel/silfab-sil-400-hc) | 400 W | -10 W, -0.5 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +150 W, cooler, +4.1 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +145 W, cooler, +3.9 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +140 W, cooler, +3.7 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +130 W, cooler, +3.7 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +130 W, cooler, +3.7 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | +135 W, cooler, +3.6 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | +135 W, cooler, +3.5 pp | --- Source: https://comparepv.com/panel/silfab-sil-410-hc Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
