About product
JA-JAM54-S31 is part of the 405MR Series — one of the most recent made by JA Solar. 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.
Another advantage is the half-cut cell technology. JA-JAM54-S31 has solar cells half the size of those installed in conventional panels. The main benefits are decreased power loss, improved longevity and better low-light performance. The efficiency of this model reaches 20.7% — well above the market’s average. Novel design solutions allow this panel to look as well as it performs. This model is just 1.18" in depth and is jet black with a sleek finish. The panel's functionality and durability are not affected by its aesthetic appeal though. JA Solar provides an industry-leading 25-year performance warranty and a 12-year product warranty.
JA Solar 405MR panels fully use the firm's innovations, which JA Solar has received several distinctions for. With PERC technology, more electricity can be produced per square foot of PV modules. As a result, there will be less clamps and racks required during installation. All of which lowers your overall expenses and accelerates the payback period.
Excellent temperature coefficient means more energy as temperature rises. Every 1.8°F hike above 77°F will decrease your panel’s efficiency by only -0.35%.
JA-JAM54-S31 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. JA Solar is committed to quality, safety, and dependability to ensure you get the finest.
JA Solar guarantees slow deterioration over the next 25 years. The performance will decline by no more than 2.5% during the first year and then by no more than 0.60% every year after that. After the 25 years are over, your modules will retain at least 83.1% of their original performance. This 405 W JA Solar solar panel also comes with a substantial 12-year product warranty.
This model's construction makes it perfect for both residential and business rooftops. Durability and strength are increased by using a strong, robust frame built from aluminum alloy. A significant snow load of up to 3600 Pa may be supported by the model. The panel's back can support 1600 Pa, assuring that even the strongest winds won't damage your system.
The panel has a sleek, all-black style that complements any roof beautifully. JA Solar 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.
