At the core of the design are **N-type bifacial cells**, which, thanks to a high bifaciality factor, generate additional energy reflected from the ground surface, setting them apart from cheaper solutions based on P-type cells. The panels feature a **transparent rear backsheet** along with tempered, anti-reflective coated glass on both sides, allowing efficient capture of diffuse and reflected light. The built-in **PID-resistant technology** and POE encapsulant minimize the risk of potential induced degradation, while near-zero LID translates into higher energy production from the very first year of operation. The SLG-X Bifacial series is well suited for commercial, industrial, and premium installations where aesthetics and durability matter, and where investors expect a low annual degradation rate and predictable LCOE over a 30-year horizon. It's a solution for anyone seeking modules with increased power density and an architectural look, ready for high-voltage systems up to 1000 V. ## Notable figures - Efficiency of 18.5% is 1.0pp below the \*\*N-type 0-400W\*\* median (19.5%) - At 184.6 W/m², this panel generates 10.3 W/m² less per unit area than \*\*N-type 0-400W\*\* median (194.9 W/m²) - -0.41%/°C temperature coefficient - 0.09pp worse than \*\*N-type 0-400W\*\* median (-0.32%/°C), expect higher hot weather losses - At 23.0 kg, weight matches the \*\*N-type 0-400W\*\* median - Bifacial design (85% factor) captures reflected light - adds 4-13% yield on ground-mount or white roof ## Questions ### Is the Silfab SLG-X Bifacial series still available for purchase? No, production of the SLG-X Bifacial series has ended and this model has been discontinued from Silfab's current lineup. Panels may still be available from distributors as remaining stock, but they are no longer manufactured. Anyone planning to extend an existing installation built on these modules should expect limited availability and confirm current stock with a supplier before purchasing. ### How do N-type bifacial cells in the Silfab SLG-X differ from standard P-type monocrystalline panels? N-type cells have a lower light-induced degradation (LID) rate than P-type cells, resulting in higher energy output from the very first year of operation. In addition, bifacial technology allows the panel to capture light reflected off the ground through the transparent backsheet on the rear side, generating several extra percentage points of energy compared to a conventional single-sided P-type panel of the same nominal power. ### What warranty comes with the Silfab SLG-X Bifacial panels and what does it cover? The manufacturer provides a 12-year product warranty covering material and workmanship defects, along with a 30-year power performance warranty guaranteeing minimum energy output over that period. This is a higher standard than the typical 25-year power warranty offered by many P-type panel manufacturers, translating into a lower projected LCOE over a three-decade system lifetime. ### Are Silfab SLG-X Bifacial panels rated for high-voltage systems up to 1000 V? Yes, SLG-X Bifacial modules are certified for a maximum system voltage of up to 1000 V, which is standard for commercial and industrial installations with large numbers of modules connected in series strings. This allows an installer to design longer strings, reducing the number of inverters and cable runs needed, thereby lowering wiring costs in larger BoS budgets. ### Is Silfab a tier-1 manufacturer, and where are SLG-X Bifacial panels made? Yes, Silfab Solar is a recognized tier-1 manufacturer headquartered in Mississauga, Canada, with its own production facilities in Canada and the United States and over 40 years of experience in the photovoltaic industry. Tier-1 status reflects the company's financial stability and long track record of bankable projects, which matters for financing commercial installations and securing favorable loan terms. ### Which installations best suit the Silfab SLG-X Bifacial series — rooftop or ground-mount? SLG-X Bifacial panels perform best in ground-mount arrays and on flat commercial or industrial roofs, where the module can be mounted over a light-colored surface (gravel, white membrane, grass) that reflects light onto the rear side. On typical pitched roofs with dark roofing material, the bifacial gain is limited, so the benefit of the technology is much smaller in that setup. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Silfab-SLG-X-360-Bifacial-SF-0G-20181016-K-Final-44ab90c69d18.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | Cooler, lighter, +4.7 pp | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | Cooler, lighter, +4.7 pp | | [Gamko New Energy GKA210M320W](https://comparepv.com/panel/gamko-new-energy-gka210m320w) | 320 W | -40 W, lighter, +4.5 pp | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | -20 W, lighter, +4.5 pp | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | Lighter, +4.5 pp | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | +20 W, lighter, +4.5 pp | | [Gamko New Energy GKA210M400W (1/2\*4\*20)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-2-4-20) | 400 W | +40 W, lighter, +4.5 pp | | [Gamko New Energy GKA210M400W (1/4\*4\*40)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-4-4-40) | 400 W | +40 W, lighter, +4.5 pp | | [Gamko New Energy GKA210M380W (1/2\*4\*19)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19) | 380 W | +20 W, lighter, +4.5 pp | | [Maxeon SPR-MAX3-400-COM](https://comparepv.com/panel/maxeon-spr-max3-400-com) | 400 W | Cooler, +4.1 pp, +10 yr warranty | | [Silfab SLG-X-350](https://comparepv.com/panel/silfab-slg-x-350) | 350 W | -10 W, -0.5 pp | | [Silfab SLG-M 370](https://comparepv.com/panel/silfab-slg-m-370) | 370 W | +10 W, cooler, +0.5 pp | | [Maxeon SPR-MAX7-475](https://comparepv.com/panel/maxeon-spr-max7-475) | 475 W | +115 W, cooler, +5.5 pp | | [Maxeon SPR-MAX7-470](https://comparepv.com/panel/maxeon-spr-max7-470) | 470 W | +110 W, cooler, +5.2 pp | | [Maxeon SPR-MAX7-465](https://comparepv.com/panel/maxeon-spr-max7-465) | 465 W | +105 W, cooler, +5.0 pp | | [Maxeon SPR-MAX6-440](https://comparepv.com/panel/maxeon-spr-max6-440) | 440 W | Cooler, +4.3 pp, +10 yr warranty | --- Source: https://comparepv.com/panel/silfab-slg-x-360 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.
