About product
SS-M 440 is part of the SS-M Series — one of the most recent made by Sonali Solar. These panels employ cutting-edge technologies to achieve superior efficiency and reliability. SS-M 440 employs monocrystalline silicon — the most efficient material for converting sunlight into electricity. Each of the model's 120 solar cells consists of a single crystal, unlike cheaper polycrystalline cells that are made of multiple crystals melted together. As a result, not only are monocrystalline panels more efficient, but they are also more resistant to degradation. To further boost the performance, Sonali Solar employs half-cut cell technology. Each of the panel’s 120 cells is only half the size of a traditional solar cell. This grants SS-M 440 lower resistive losses and better shade tolerance. At 18.57% efficiency, SS-M 440 offers surprising performance for its weight and size. Sonali Solar paid as much attention to durability as they did to performance. SS-M 440 is guaranteed to retain at least 85.5% of output after 25 years. Product warranty for this panel lasts 12 years.
An already high efficiency of 18.57% is further enhanced by monocrystalline 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, SS-M 440 outputs 440 W of power.
The heat is less of a threat with this module: with one of the lowest temperature coefficients in the industry, SS-M 440 loses just 0.37% of efficiency for every 1.8°F above 77°F.
Sonali 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.
Slow degradation over the next 25 years is guaranteed by Sonali Solar. The performance will decrease no more than 2.5% during the first year and then will be limited to 0.50% annually. Your modules will retain at least 85.5% of original performance after the 25 years are over. This 440 W Sonali Solar solar panel also comes with a generous 12-year product warranty.
The 1.38" frame made from anodized aluminum and a layer of protective tempered glass make this module resistant to the foulest of weather. The front side of the modules can resist a 5400 Pa load, and the back side 3600 Pa.
