550W Bifacial Solar Panel | High Efficiency | 144 Half-Cut PERC Cells | Wholesale Solar Panels | 1 Pallet (36 Panels)

HS72-F-550-MN is part of the HT72-18X(PD)-F-550 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.

To further boost the performance, GreenWatts employs half-cut cell technology. Each of the panel’s 144 cells is only half the size of a traditional solar cell. This grants HS72-F-550-MN lower resistive losses and better shade tolerance. Given its size and weight, HS72-F-550-MN efficiency of 21.3% 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. The innovations made the appearance of the panel as impressive as the specs. A mere 1.18″ thick, this model is completely black with a smooth surface. This beauty doesn’t compromise the quality or reliability of the panel. GreenWatts provides 30 years of product warranty and guarantees that after 30 years, performance will be at 83.21% or more.

More power and efficiency

An already high efficiency of 21.3% is further enhanced by PERC technology. By adding a solid PID resistance and special glass lamination on top, the manufacturer ended up with an efficient and very durable model. Under standard test conditions, HS72-F-550-MN outputs 550 W of power.

Better performance at high temperatures

Excellent temperature coefficient means more energy as temperature rises. Every 1.8°F hike above 77°F will decrease your panel’s efficiency by only -0.33%.

Quality and reliability

HS72-F-550-MN 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.

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 0.51%. After 30 years, the modules will retain more than 83.21% of their initial output.

Certified for the worst environmental conditions

HS72-F-550-MN is PID, salt, acid, and ammonia resistant. It can also bear mechanical loads of up to 5400 Pa on the front and 2400 Pa on the back. This durability is mostly owing to the 1.18″ thick aluminum alloy frame and a layer of protective glass.

Stunning black aesthetics

The sleek, all-black aesthetics of the panel will complement any rooftop. By using a variety of treatments and selection criteria, the producer guarantees high quality cell color. Engineers at GreenWatts employ smaller gauge wires to link the cells together, creating a seamless appearance.
