This Sunmac 405W solar module is part of the ZXM7-SHDB144 Series. 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, Sunmac Solar employs half-cut cell technology. Each of the panel’s 108 cells is only half the size of a traditional solar cell. This grants 405W lower resistive losses and better shade tolerance. As a result, the panel achieves an impressive efficiency of 20.74%. Cell surface, back foil and frame are completely black, giving the model unrivaled aesthetics. Sunmac Solar offers 25 years of product warranty and guarantees 84.8% of original performance after 25 years of operation.

More power and efficiency
An already high efficiency of 20.74% 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, 405W outputs 405 W of power.
Keeping the cool in high temperatures
405W manages to stay efficient even at high temperatures. For every 1.8°F above 77°F, it loses just -0.35% in efficiency, allowing you to make the most of the sunniest hours.
High quality standards
Sunmac Solar 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.
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 25th year will be no more than 0.55%. After 25 years, the modules will retain more than 84.8% of their initial output.
Certified for the most extreme environmental conditions
PID, salt, acid and ammonia cannot harm 405W. 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 anodized aluminum frame are the primary reasons for its toughness.
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 Sunmac Solar employ smaller gauge wires to link the cells together, creating a seamless appearance.
