Installed on pole mount for RV park. Reliable power all summer even partial shade. Long warranty sold me
Solid performer. Had em up 2 months output steady. Bifacial gain bout 15% on my setup.
six months in and no issues. they work every day and produce good power. installation was straightforward with standard racking
One thing I didnt expect is how well these perform in cold weather. Even when its freezing they still put out good power. The snow slides off pretty easy too
bought these for my farm and theyre doing exactly what i needed. cant complain about the price for panels with 30 year warranty
Been using these for my home system since March. They work as advertised. Not much else to say - they sit on my roof and make electricity. The efficiency rating seems accurate based on my monitoring system.
installed these panels and they've been running for 3 months now. power production is actually higher than the rated on sunny days. very happy with this purchase

Good panels overall. Heavy but solid construction. Outputting rated power consistently even in partial cloud. Wish pallet had 32 for round numbers but 31 works fine.

Solid performer. Had em up 2 months output steady at 21% eff. Bifacial gain bout 15% on my setup.
snow here melts fast cause rear side grabs light. averaging 650w peak
installed 31 panels and they've been running for 3 months now. power production is actually higher than the rated 560w on sunny days. very happy with this purchase

About product

CHSM66M(DG)/F-BH-645 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-645 lower resistive losses and better shade tolerance. Not surprisingly, the efficiency of this module is quite high – 20.8%. 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.

  • 645 W power output
  • 132 half-cut PERC cells
  • 20.8% 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 20.8% 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-645 outputs 645 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 645 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.
