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. These panels employ cutting-edge technologies to achieve superior efficiency and reliability.

The use of half-cut cell technology is an additional perk. The solar cells 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. Given its size and weight, the efficiency of 21.48% is quite impressive. 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. Yibai Solar provides a 12-year product warranty. Stable power output is also guaranteed — a performance warranty will protect you for 25 years.

More power and efficiency

An already high efficiency of 21.48% 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, it outputs 555W of power.

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 0.29%.

Quality and reliability

PERC Monofacial 555W Solar Panel 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. Yibai Solar is committed to quality, safety, and dependability to ensure you get the finest.

Low degradation for increased lifespan

The amount of power output loss experienced by these panels during the first year of operation will not exceed 2%. The average yearly power drop from the second to the 25th year will not surpass 0.55%. After 25 years, the module will still produce more than 84.8% of its initial output.

Certified for the most extreme environmental conditions

PID, salt, acid, and ammonia cannot harm PERC Monofacial 555W Solar Panel. 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 a 1.18″ thick anodized aluminum frame are the primary reasons for its toughness.
