Product Description

SIL-400 NU is a model that uses a number of technologies to bring durability and performance to the next level. This panel takes full advantage of the Passivated Emitter Rear Contact (PERC) technology that allows it to capture up to 12% more energy. All thanks to a reflective layer on the back. This design maximizes the number of photons absorbed by solar cells. The efficiency of this model reaches 19.6% — well above the market’s average. Silfab offers 25 years of product warranty and guarantees 82.6% of original performance after 30 years of operation.

  • 400 W power output
  • 72 full-sized PERC cells
  • 19.6% efficiency
  • 1500 V DC maximum system voltage
  • MC4 connectors
  • 25-year product and 30-year performance warranties


High efficiency of 19.6%

Silfab NU panels take full advantage of the company’s technologies that have won Silfab multiple awards. This PERC option offers higher power output per square foot of PV modules. This means quicker installation times and fewer clamps and racks. All of which reduces your overall costs, shortening the payback time.

Better performance at high temperatures

Excellent temperature coefficient means more energy as temperature rises. Every 1.8°F hike above 77°F will decrease your panel’s efficiency by only 0.38%.

Quality and reliability

SIL-400 NU receives multiple quality checks throughout the manufacturing process and is subject to stringent quality and reliability testing. The manufacturing facilities are highly automated, eliminating the risk of human error. Silfab is dedicated to quality, safety and reliability to ensure you get the very best.

Low degradation for a longer lifespan

These panels will lose no more than 2.9% of their power output in the first year of service. From the 2nd year to the 30th year, the average annual power decline will be no more than 0.50%. The module retains over 82.6% of its original output after 30 years. Guaranteed by Silfab.

Certified for the most challenging environmental conditions

SIL-400 NU is resistant to PID, salt, acid and ammonia. It can also withstand up to 5400 Pa mechanical load on the front and 2400 Pa on the back. Such robustness is mainly due to the 1.5" thick anodized aluminum frame and a layer of protective glass.
