About product

HS66-F-665-MN is part of the HT66-210(PD)-F-665 Series — one of the most recent made by GreenWatts. These panels employ cutting-edge technologies to achieve superior efficiency and reliability. 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.

Half-cut cell technology adds a few more percent to the overall performance, making this model a great example of efficiency. GreenWatts made solar cells in HS66-F-665-MN two times smaller than the standard size, thus reducing power loss and improving low-light behavior. The efficiency of this model reaches 21.4% — well above the market’s average. 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. GreenWatts offers 30 years of product warranty and guarantees 83.21% of original performance after 30 years of operation.

  • 132 half-cut PERC cells
  • 665 W nameplate capacity
  • 21.4% efficiency
  • 1500 V DC maximum system voltage
  • MC4 connectors
  • 30 years of product and 30 years of performance warranty

Higher efficiency of up to 21.4%

HS66-F-665-MN guarantees the highest power output. PERC technology and potent antireflective coating result in 21.4% module efficiency. This is significantly higher than average, which will result in substantial extra savings over the years of operation.

Exceptional performance in scorching weather

At high working temperatures, a low temperature coefficient equals increased energy generation. Every 1.8°F over 77°F results in a model's efficiency loss of just -0.33 percent.

High quality standards

GreenWatts 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.

Reliability and degradation resistance

GreenWatts guarantees limited degradation over the ensuing 30 years. The performance will only degrade by a maximum of 2% the first year, and then only by a maximum of 0.51% yearly after that. After the 30 years are over, your modules will still show at least 83.21% of nominal capacity. A substantial 30-year product warranty is also included with this 665 W GreenWatts solar panel.

Certified for the most extreme environmental conditions

PID, salt, acid and ammonia cannot harm HS66-F-665-MN. Furthermore, it has a mechanical load resistance of up to 5400 Pa in the front and 2400 Pa in the back. A layer of protective glass and 1.18" thick aluminum alloy frame are the primary reasons for its toughness.
