Sonali Solar 420W Solar Panel 108 Cell All Black SS-420-108M-B Wholesale in pallet 31 panels (min 3 pallets)

Sonali SS-420-108M-B is a PV module fit for both residential and commercial applications. Sonali engineers made the TopCon series durable and efficient while minimizing the amount of useful space required for their operation. 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. Sonali made solar cells in SS-420-108M-B two times smaller than the standard size, thus reducing power loss and improving low-light behavior. As a result, the panel achieves an impressive efficiency of 21.48%. Novel design solutions allow this panel to look as well as it performs. This model is just 1.37" in depth and is jet black with a sleek finish. The panel's functionality and durability are not affected by its aesthetic appeal though. Sonali offers 25 years of product warranty and guarantees 80.02% of original performance after 30 years of operation.

Great productivity through the latest innovations

This Sonali panel provides 420 W power at 21.48% efficiency. High energy production levels are achieved through the usage of the latest advances in the solar industry, including PERC technology and state-of-the-art antireflective coating. An efficient panel yields more per square foot and pays for itself faster.

Exceptional performance in hot temperatures

A low temperature coefficient provides more energy output at high working temperatures. SS-420-108M-B loses just -0.35 percent efficiency for every 1.8°F over 77°F.

High quality standards

Multiple tests are part of the Sonali tight production requirements, which offer the highest level of quality assurance. Because of the facilities' high degree of automation, the business is able to uphold strict standards and minimize the number of warranty claims to an absolute minimum.

Reliability and degradation resistance

Sonali guarantees limited degradation over the ensuing 30 years. The performance will only degrade by a maximum of 2% the first year, and then only by a maximum of 0.62% yearly after that. After the 30 years are over, your modules will still show at least 80.02% of nominal capacity. A substantial 25-year product warranty is also included with this 420 W Sonali solar panel.

Certified for the most challenging environmental conditions

SS-420-108M-B is resistant to PID, salt, acid and ammonia. It can also withstand up to 5400 Pa mechanical load on the front and 2400 Pa on the back. Such robustness is mainly due to the 1.37" thick anodized aluminum alloy frame and a layer of protective glass.

Outstanding all-black design

The panel has a sleek, all-black style that complements any roof beautifully. Sonali uses unique treatment and selection procedures to guarantee optimum cell color. The cells are connected by thinner wires, and from a distance, the surface of the modules seems seamless and smooth.
