About product


REC365AA BLK is part of the Alpha Series — one of the most recent made by REC. 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. 

Half-cut cell technology adds a few more percent to the overall performance, making this model a great example of efficiency. REC made solar cells in REC365AA BLK two times smaller than the standard size, thus reducing power loss and improving low-light behavior. The efficiency of this model reaches 20.9% — well above the market’s average. Cell surface, back foil and frame are completely black, giving the model unrivaled aesthetics. REC provides a 20-year product warranty. Stable power output is also guaranteed — performance warranty will protect you during 25 years. 

  • 120 half-cut PERC cells
  • 365 W nameplate capacity
  • 20.9% efficiency
  • 1000 V DC maximum system voltage
  • MC4 connectors
  • 20 years of product and 25 years of performance warranty

Great productivity through the latest innovations

This REC panel provides 365 W power at 20.9% efficiency. High energy production levels are achieved through the usage of the latest advances in the solar industry, including PERC technology and state-of-the-art antireflective coating. An efficient panel yields more per square foot and pays for itself faster.

Heat-resistant performance

The heat is less of a problem with this module: with one of the industry's lowest temperature coefficients, REC365AA BLK loses just 0.24% of efficiency for every 1.8°F over 77°F.

High quality standards

Multiple tests are part of the REC tight production requirements, which offer the highest level of quality assurance. Because of the facilities' high degree of automation, the business is able to uphold strict standards and minimize the number of warranty claims to an absolute minimum.

Low degradation for a longer lifespan

These panels will lose no more than 2% of their power output in the first year of service. From the 2nd year to the 25th year, the average annual power decline will be no more than 0.26%. The module retains over 91.76% of its original output after 25 years. Guaranteed by REC.

Certified for the most extreme environmental conditions

PID, salt, acid and ammonia cannot harm REC365AA BLK. Furthermore, it has a mechanical load resistance of up to 7000 Pa in the front and 4666 Pa in the back. A layer of protective glass and 1.2" thick anodized aluminum frame are the primary reasons for its toughness.

Outstanding all-black design

The panel features all-black design which looks great on any roof. The manufacturer ensures excellent cell color by special treatment and selection processes. REC engineers use thinner wires to connect the cells together, and at a distance the surface of the modules appears smooth and uninterrupted.
