Silfab 520W Solar Panel 132 Cell SIL-520-QM Assembled in the USA Commercial 696 panels per Container

Silfab SIL-520 is a PV module fit for both residential and commercial applications. Silfab engineers made the QM series durable and efficient while minimizing the amount of useful space required for their operation. 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.

Another advantage is the half-cut cell technology. SIL-520 has solar cells half the size of those installed in conventional panels. The main benefits are decreased power loss, improved longevity and better low-light performance. The efficiency of this model reaches 21.9% — well above the market’s average. The innovations made the appearance of the panel as impressive as the specs. A mere 1.37" thick, this model is completely black with a smooth surface. This beauty doesn’t compromise the quality or reliability of the panel. Silfab provides a 25-year product warranty. Stable power output is also guaranteed — performance warranty will protect you during 30 years.

Increased efficiency of up to 21.9 percent

SIL-520 ensures maximum power production. The combination of PERC technology and a powerful antireflective coating results in 21.9 percent module efficiency. This is much greater than the average, resulting in significant extra savings over the years of production.

Excellent performance in adverse weather

Low temperature coefficient means greater energy production at high operating temperatures. SIL-520 loses just -0.29% of efficiency for every 1.8°F above 77°F.

Quality and reliability

SIL-520 is subject to rigorous quality and reliability testing as well as many quality checks throughout the production process. The level of automation in the manufacturing facilities virtually eliminates human error. To guarantee that you receive the finest, REC is committed to quality, safety and dependability.

Low degradation for a longer lifespan

These panels will lose no more than 2% 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 0.54%. The module retains over 82.34% of its original output after 30 years. Guaranteed by Silfab.

A panel that can handle hail, wind and snow

The 1.37" frame built of anodized aluminum and a layer of protective tempered glass make this module weather-resistant. The front side of the modules can withstand a 5400 Pa load, whereas the back side can withstand a 2400 Pa load.

Stunning black aesthetics

The sleek, all-black aesthetics of the panel will complement any rooftop. By using a variety of treatments and selection criteria, the producer guarantees high quality cell color. Engineers at Silfab employ smaller gauge wires to link the cells together, creating a seamless appearance.
