About product

Among the newest offerings of Regitec, RMH72-550S1 is part of the RMH72-525~550S1 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.

The use of half-cut cell technology is an additional perk. The solar cells of RMH72-550S1 are half the size of those found in standard panels. Major advantages include reduced power consumption, extended life and enhanced efficiency in low-light conditions. The efficiency of this model reaches 21.3% — well above the market’s average. Regitec paid as much attention to durability as they did to performance. RMH72-550S1 is guaranteed to retain at least 80.68% of output after 30 years. Product warranty for this panel lasts 25 years.

  • 550 W power output
  • 144 half-cut PERC cells
  • 21.3% efficiency
  • 1500 V DC maximum system voltage
  • MC4-compatible connectors
  • 25-year product warranty and 30-year performance warranty

Increased efficiency of up to 21.3%

RMH72-550S1 ensures maximum power production. 21.3 percent module efficiency is achieved using PERC technology and a powerful antireflective coating. This is much greater than the norm, resulting in significant additional savings throughout the years of operation.

Excellent performance in adverse weather

Low temperature coefficient means greater energy production at high operating temperatures. RMH72-550S1 loses just -0.35% of efficiency for every 1.8°F above 77°F.

High quality standards

Regitec stringent production requirements include various tests to guarantee high quality. The facilities are highly automated, allowing the manufacturer to maintain high standards while keeping warranty claims to a minimum.

Reliability and degradation resistance

Regitec guarantees limited degradation over the ensuing 30 years. The performance will only degrade by a maximum of 3% the first year, and then only by a maximum of 0.56% yearly after that. After the 30 years are over, your modules will still show at least 80.68% of nominal capacity. A substantial 25-year product warranty is also included with this 550 W Regitec solar panel.

A panel that can handle hail, wind and snow

The 1.38" frame made from anodized aluminum alloy 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.
