The Silfab SIL-570 XM+ (Commercial NTC) series are bifacial modules designed for maximum energy yield in commercial installations, where high power density and stable operation in challenging conditions are crucial. The use of N-type cells in NTC/TOPCon technology results in a significantly lower degradation rate over time and improved production predictability - particularly important when modeling investment profitability.

These panels are distinguished by superior performance at high temperatures, resulting in lower summer performance losses compared to many standard P-type silicon-based modules. In practice, this means more consistent energy generation and easier achievement of projected annual yields. An additional benefit is higher sensitivity to diffuse light - installations remain productive for longer during cloudy conditions, morning, and afternoon. The bifacial design provides additional yield from the rear side on bright roofs, carports, and ground-mounted systems. This series is designed for halls, warehouses, service facilities, and PV farms, where reliability and low LCOE are key.

Common questions

6 answered
What is the warranty on the Silfab SIL-570 XM+ and what does it cover?
The SIL-570 XM+ series comes with a 25-year product warranty covering defects in materials and workmanship, and a 30-year power output warranty. After 12 years the module retains at least 94.7% of rated power, and after 30 years at least 89.3%. This is among the longest power warranties available on the market, directly strengthening the financial model for commercial PV installations.
What is the temperature coefficient of the SIL-570 XM+ and how well does it handle summer heat?
The SIL-570 XM+ has a temperature coefficient of Pmax of just -0.29%/°C, which is significantly better than typical P-type PERC modules at around -0.35%/°C. In practice this means lower power losses on hot summer days. The N-type NTC/TOPCon cell technology is responsible for this thermal advantage and translates into higher annual energy yield.
Are the Silfab SIL-570 XM+ panels a good fit for carports or ground-mount systems where bifacial gain matters?
Yes, the SIL-570 XM+ is a bifacial module, generating power from both the front and rear sides. On reflective surfaces such as concrete, light gravel, or grass in carports and ground-mount arrays, the rear-side bifacial gain can add several percentage points to annual yield. Maximizing bifacial gain requires adequate module clearance above the ground surface.
What are the dimensions and weight of the SIL-570 XM+ and will a standard racking system handle it?
The panel measures 2278 x 1133 x 35 mm and weighs 28.5 kg. These are standard dimensions for a 144-cell commercial module. Existing steel racking may need rail-spacing verification — consult a structural engineer who can account for the rated front load of 5400 Pa (snow/wind) and rear load of 2400 Pa, along with local wind zone requirements.
How does the TOPCon N-type technology in the SIL-570 XM+ compare to older PERC modules?
TOPCon (Tunnel Oxide Passivated Contact) N-type cells deliver higher efficiency (22.1% for the SIL-570 XM+), lower initial light-induced degradation (LID), and better performance at elevated temperatures compared to standard P-type PERC modules. Lower annual degradation means more cumulative energy over 30 years of operation, directly reducing the installation's LCOE.
Is Silfab a reliable manufacturer and is the SIL-570 XM+ series still available?
Silfab Solar is a Canadian manufacturer headquartered in Canada and ranked Tier 1 by Bloomberg NEF, confirming its financial stability and manufacturing quality. The SIL-570 XM+ series is active and currently available. Contact authorized distributors or PV system integrators for current stock levels and delivery schedules in your region.
