SS-M-390-B is a high-performance solar module made by Sonali. 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.
To further boost the performance, Sonali employs half-cut cell technology. Each of the panel’s 108 cells is only half the size of a traditional solar cell. This grants SS-M-390 lower resistive losses and better shade tolerance. At 20.19% efficiency, SS-M-390-B offers surprising performance for its weight and size. Cell surface, back foil and frame are completely black, giving the model unrivaled aesthetics. Sonali provides an industry-leading 25-year performance warranty and a 25-year product warranty.

Higher efficiency of up to 20.19%
The highest power output is guaranteed by Sonali SS-M-390-B with an efficiency of up to 20.19%. Such outstanding performance is the product of PERC technology and an effective antireflective coating. This is notably above average, which will translate into significant additional savings over the course of operation.
Improved efficiency at high temperatures
Greater energy as temperature rises is a mark of a good temperature coefficient. Your panel's efficiency will drop by just -0.37% for every 1.8°F increase over 77°F.
Quality and reliability
SS-M-390-B 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. Sonali 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 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 SS-M-390-B. Furthermore, it has a mechanical load resistance of up to 5400 Pa in the front and 3600 Pa in the back. A layer of protective glass and 1.38" thick anodized aluminum frame are the primary reasons for its toughness.
Outstanding all-black design
The panel features all-black design which looks great on any roof. The manufacturer ensures excellent cell color by special treatment and selection processes. Sonali engineers use thinner wires to connect the cells together, and at a distance the surface of the modules appears smooth and uninterrupted.
