GreenWatts 550W Solar Panel 144 Cell Bifacial HS72-18X-550W Wholesale 31 panels per pallet

HS72-18X-550W is part of the HT72-18X(PD)-F Double Glass Series — one of the most recent made by GreenWatts. These panels employ cutting-edge technologies to achieve superior efficiency and reliability. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight.

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 HS72-18X-550W two times smaller than the standard size, thus reducing power loss and improving low-light behavior. Not surprisingly, the efficiency of this module is quite high – 21.3%. 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 a 25-year product warranty and guarantees 84.95% of original performance after 30 years of operation.

More energy and efficiency

The PERC technology further improves an already excellent efficiency of 21.3 percent. A reliable PID resistance and a unique glass lamination were added by the maker, which ultimately produced a model that was effective and extremely durable. HS72-18X-550W produces 550 W of power under typical test settings.

Heat-resistant performance

The heat is less of a threat with this module: with one of the lowest temperature coefficients in the industry, HS72-18X-550W loses just -0.326% of efficiency for every 1.8°F above 77°F.

Quality and reliability

HS72-18X-550W 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. GreenWatts is committed to quality, safety, and dependability to ensure you get the finest.

Reliability and degradation resistance

GreenWatts guarantees slow deterioration over the next 30 years. The performance will decline by no more than 2% during the first year and then by no more than 0.45% every year after that. After the 30 years are over, your modules will retain at least 84.95% of their original performance. This 550 W GreenWatts solar panel also comes with a substantial 25-year product warranty.

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.
