About product

Silfab SIL-370 is a PV module fit for both residential and commercial applications. Silfab engineers made the NX series durable and efficient, while minimizing the amount of useful space required for their operation. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight. As a result, the panel achieves impressive efficiency of 20.2%. Cell surface, back foil and frame are completely black, giving the model unrivaled aesthetics. Silfab provides an industry-leading 30-year performance warranty and a 25-year product warranty.

  • 66 full-sized PERC cells
  • 370 W nameplate capacity
  • 20.2% efficiency
  • 1000 V DC maximum system voltage
  • MC4 connectors
  • 25 year of product and 30 year of performance warranty

Great productivity through the latest innovations

This Silfab panel provides 370 W power at 20.2% efficiency. High energy production levels are achieved through the usage of the latest advances in the solar industry, including PERC technology and state-of-the-art antireflective coating. An efficient panel yields more per square foot and pays for itself faster.

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 0.36%.

High quality standards

Silfab strict manufacturing standards include multiple tests to provide extreme quality assurance. The facilities are highly automated, allowing the company to maintain high standards and keep the level of warranty claims very low.

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.

Enhanced frame design

SIL-370 design makes it ideal for residential and commercial rooftops. Strong 1.5" frame made from anodized aluminum increases durability and strength. The model can support a heavy snow load up to 5400 Pa. The back of the panel can handle 4000 Pa, ensuring that your system will survive the strongest of winds.

Outstanding all-black design

The panel features all-black design which looks great on any roof. The manufacturer ensures excellent cell color by special treatment and selection processes. Silfab engineers use thinner wires to connect the cells together, and at a distance the surface of the modules appears smooth and uninterrupted.
