JA Solar 620W Solar Panel 132 Cell Bifacial JA-JAM66-D45-620LB

JA Solar JA-JAM66-D45-620LB is a PV module fit for both residential and commercial applications. JA Solar engineers made the Premium series durable and efficient while minimizing the amount of useful space required for their operation. The solar cells of JA-JAM66-D45-620LB are half the size of those found in standard panels. Major advantages include reduced power consumption, extended life, and enhanced efficiency in low-light conditions. The efficiency of this model reaches 23.0% — well above the market’s average. And while conventional panels absorb photons only on one side, bifacial modules absorb photons on both sides simultaneously. Thanks to the technology, this model can be up to 30% more efficient. JA Solar provides a 12-year product warranty. Stable power output is also guaranteed — linear power output warranty will protect you for 30 years.

Increased power and efficiency

N-Type cell technology improves on an already high efficiency of 23.0 percent. The manufacturer created an efficient and highly durable model by adding a robust PID resistance and unique glass lamination on top. JA-JAM66-D45-620LB produces 620 W of power under standard test conditions.

Heat-resistant performance

The heat is less of a problem with this module: with one of the industry's lowest temperature coefficients, JA-JAM66-D45-620LB loses just -0.29% of efficiency for every 1.8°F over 77°F.

Quality and reliability

JA-JAM66-D45-620LB is subject to rigorous quality and reliability testing as well as many quality checks throughout the production process. The level of automation in the manufacturing facilities virtually eliminates human error. To guarantee that you receive the finest, JA Solar is committed to quality, safety, and dependability.

Low degradation for increased lifespan

The amount of power output loss experienced by these panels during the first year of operation will not exceed 1%. The average yearly power drop from the second to the 30th year will not surpass 0.40%. After 30 years, the module will still produce more than 87.4% of its initial output.

A panel that can handle hail, wind, and snow

The 1.38" frame made from anodized aluminum alloy 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 2400 Pa.
