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. ## Notable figures - Efficiency of 22.1% matches the \*\*N-type 550-600W\*\* median - Power density of 220.8 W/m² is 3.7 W/m² below \*\*N-type 550-600W\*\* median (224.5 W/m²) - needs more roof space - Temperature coefficient of -0.29%/°C matches the \*\*N-type 550-600W\*\* median - At 28.5 kg, weight matches the \*\*N-type 550-600W\*\* median - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces ## Questions ### 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.
