About product

FEOC-Compliant Solar Panels

These solar panels are compliant with FEOC standards and contain 43% Domestic Content. Compliance confirmation available upon request.

156HC M10 NTYP SL 640W is a model that uses a number of technologies to bring durability and performance to the next level. This panel has solar cells half the size of those found in standard panels. Major advantages include reduced power consumption, extended life, and enhanced efficiency in low-light conditions.

Not surprisingly, the efficiency of this module is quite high – 22.90%. And while conventional panels absorb photons only on one side, bifacial modules absorb photons on both sides simultaneously. Thanks to the technology, this model can be up to 30% more efficient. Heliene offers a 15-year product warranty and guarantees 89.40% of the original performance after 25 years of operation.

  • 640 W power output
  • 156 half-cut TOPCon cells
  • 22.90% efficiency
  • 1500 V DC maximum system voltage
  • Multi-Contact/ Stäubli MC4 connectors
  • 15-year product warranty and 25-year linear performance guarantee

Great productivity through the latest innovations

This Heliene panel provides 640 W power at 22.90% efficiency. High energy production levels are achieved through the usage of the latest advances in the solar industry, including TOPCon technology and state-of-the-art antireflective coating. An efficient panel yields more per square foot and pays for itself faster.

Keeping cool in high temperatures

Even under extreme heat, 156HC M10 NTYP SL 640W maintains high efficiency. You may take advantage of the sunniest hours because it loses just -0.3% of efficiency for every 1.8°F over 77°F.

High-quality standards

Heliene's 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 1% of their power output in the first year of service. From the 2nd year to the 25th year, the average annual power decline will be no more than 0.4%. The module retains over 89.40% of its original output after 25 years. Guaranteed by Heliene.

A panel that can handle hail, wind, and snow

The 1.38" frame, built of anodized aluminum alloy 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.
