Astronergy 640W Solar Panel 132 Cell Bifacial CHSM66M(DG)/F-BH-640 Commercial 527 panels per Container (Truckload)

CHSM66M(DG)/F-BH-640 is a model that uses a number of technologies to bring durability and performance to the next level. 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.

To further boost the performance, Astronergy employs half-cut cell technology. Each of the panel’s 132 cells is only half the size of a traditional solar cell. This grants CHSM66M(DG)/F-BH-640 lower resistive losses and better shade tolerance. Not surprisingly, the efficiency of this module is quite high – 20.6%. And while conventional panels use only one side to absorb photons, bifacial modules employ both sides at the same time. Thanks to the technology, this model can be up to 30% more efficient. Astronergy provides 15 years of product warranty and guarantees that after 30 years, performance will be at 84.95% or more.

• 640 W power output
• 132 half-cut PERC cells
• 20.6% efficiency
• 1500 V DC maximum system voltage
• HCB40 / MC4-EVO2 (optional) connectors
• 15-year product warranty and 30-year linear power warranty

More power and efficiency

An already high efficiency of 20.6% is further enhanced by PERC 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, CHSM66M(DG)/F-BH-640 outputs 640 W of power.

High-quality standards

Astronergy's 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.

Reliability and degradation resistance

Slow degradation over the next 30 years is guaranteed by Astronergy. The performance will decrease no more than 2% during the first year and 0.45% annually thereafter. Your modules will retain at least 84.95% of their original performance after 30 years. This 640 W Astronergy solar panel also comes with a generous 15-year product warranty.

Enhanced frame design

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 alloy. A significant snow load of up to 5400 Pa may be supported by the model. The panel's back can support 2400 Pa, assuring that even the strongest winds won't damage your system.
