About product

Heliene 72M-340 is a PV module fit for both residential and commercial applications. Heliene engineers made the 72M 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.

Heliene employs full-sized solar cells for this model. Given its size and weight, 72M-340 efficiency of 17.8% is quite impressive. Heliene provides an industry-leading 25-year linear performance guarantee and a 10-year product warranty.

  • 340 W power output
  • 72 full-sized PERC cells
  • 17.8% efficiency
  • 1000/1500 V DC maximum system voltage
  • MC4 connectors
  • 10-year product warranty and 25-year linear performance guarantee

Higher efficiency of up to 17.8%

72M-340 guarantees the highest power output. PERC technology and potent antireflective coating result in 17.8% module efficiency. This is significantly higher than average, which will result in substantial extra savings over the years of operation.

Exceptional performance in hot temperatures

A low temperature coefficient provides more energy output at high working temperatures. 72M-340 loses just -0.39 percent efficiency for every 1.8°F over 77°F.

Quality and reliability

72M-340 undergoes various quality checks during the production process and is subjected to serious quality and reliability testing. Manufacturing facilities are highly automated, removing the possibility of human errors. Heliene is committed to quality, safety, and dependability to ensure you get the finest.

Enhanced frame design

This model's construction makes it perfect for both residential and business rooftops. Durability and strength are increased by using a strong, robust frame built from anodized aluminum alloy.
