About product
JAM54-S31 is a model that uses a number of technologies to bring durability and performance to the next level. 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. JA Solar made solar cells in JAM54-S31 two times smaller than the standard size, thus reducing power loss and improving low-light behavior. Given its size and weight, JAM54-S31 efficiency of 19.7% is quite impressive. 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.
The highest power output is guaranteed by JA Solar JAM54-S31 with an efficiency of up to 19.7%. 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.
A low temperature coefficient provides more energy output at high working temperatures. JAM54-S31 loses just 0.275 percent efficiency for every 1.8°F over 77°F.
JAM54-S31 receives multiple quality checks throughout the manufacturing process and is subject to stringent quality and reliability testing. The manufacturing facilities are highly automated, eliminating the risk of human error. JA Solar is dedicated to quality, safety and reliability to ensure you get the very best.
JA Solar guarantees slow deterioration over the next 25 years. The performance will decline by no more than 2% during the first year and then by no more than 0.55% every year after that. After the 25 years are over, your modules will retain at least 84.8% of their original performance. This 385 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 anodized aluminum. 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.
