REC Alpha 390W Solar Panel 132 cell REC390AA

REC390AA 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. 

The use of half-cut cell technology is an additional perk. The solar cells of REC390AA 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. At 21.08% efficiency, REC390AA offers surprising performance for its weight and size. 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. 

• 132 half-cut PERC cells
• 390 W nameplate capacity
• 21.08% efficiency
• 1000 V DC maximum system voltage
• MC4 connectors
• 20 years of product and 25 years of performance warranty

Increased efficiency of up to 21.08 percent

REC390AA ensures maximum power production. The combination of PERC technology and a powerful antireflective coating results in 21.08 percent module efficiency. This is much greater than the average, resulting in significant extra savings over the years of production.

Improved efficiency at high temperatures

Greater energy as temperature rises is a mark of a good temperature coefficient. Your panel's efficiency will drop by just 0.26% for every 1.8°F increase over 77°F.

High quality standards

REC 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.

Low degradation for increased lifespan

The amount of power output loss experienced by these panels during the first year of operation will not exceed 2%. The average yearly power drop from the second to the 25th year will not surpass 0.25%. After 25 years, the module will still produce more than 92% of its initial output.

A panel that can handle hail, wind and snow

This module is weatherproof due to the 1.2" frame manufactured from anodized aluminum and a layer of safety tempered glass. The modules' front and rear sides can withstand loads of 7000 and 4000 Pa, respectively.

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.
