About product

Among the newest offerings of HT SAAE, HT72 18X is part of the MULTIWAY series. These panels use state-of-the-art technology to achieve high efficiency and dependability. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight. 

To further boost the performance, HT SAAE employs half-cut cell technology. Each of the panel’s 144 cells is only half the size of a traditional solar cell. This grants HT72 18X lower resistive losses and better shade tolerance. Given its size and weight, HT72 18X efficiency of 21.1% is quite impressive. And while conventional panels use only one side to absorb photons, bifacial modules employ both sides at the same time. Thanks to the technology, this model can be up to 30% more efficient. HT SAAE offers 12 years of product warranty and guarantees 80.6% of original performance after 30 years of operation. 

  • 144 half-cut PERC cells
  • 545 W nameplate capacity
  • 21.1% efficiency
  • 1500 V DC maximum system voltage
  • MC4 connectors
  • 12 years of product and 30 years of performance warranty

Outstanding productivity integrating the newest advances

This panel's manufacturer offers power output of 545 W at 21.1 percent efficiency. High energy production levels are attained by utilizing the most recent developments in the solar sector. A more productive panel produces more per square foot and pays for itself more quickly.

Improved performance at hot temperatures

A high temperature coefficient translates to more energy as the temperature rises. Every 1.8°F increase over 77°F reduces the efficiency of your panel by just **t coef**%.

Quality and reliability

HT72 18X 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 increased longevity

In the first year of service, these panels will lose no more than 2% of their power output. The average yearly power drop from the second to the 30th year will be no more than 0.60%. After 30 years, the modules will retain more than 80.6% of their initial output.

A panel that can handle hail, wind and snow

The 1.37" frame made from anodized aluminum and a layer of protective tempered glass make this module resistant to the foulest of weather. The front side of the modules can resist a 5400 Pa load, and the back side 2400 Pa.
