About product

REC 370 AA from Alpha Series is a 120-cell solar panel from a well-known manufacturer. The main difference from other models in this product line is the white backsheet. Developed by solar experts from Germany and Singapore, this module combines the best qualities of monocrystalline and thin-film panels. The REC 370 Alpha Black panel offers better performance at high temperatures and fights the shading better.

  • Rated power output: 370W
  • 120 half-cut cells
  • Peak efficiency: 21.2% 
  • White backsheet gives the module a fresh look
  • Better performance at high temperatures
  • Better shading tolerance 

Great efficiency of 21.2%

The efficiency of 21.2%, that REC Alpha HJT 370W provides, is much higher than that of conventional modules. You can use the available space more efficiently with these modules. HJT technology improves the performance of REC 370 watt solar panels at high temperatures.

Improved shading tolerance

“Twin panel” design gives REC Alpha 370W better shading tolerance. REC was the company that introduced this technology in 2014 and it has been used ever since with great success.

Outstanding reliability

30 mm thin aluminum frames of REC 370W panels ensure high resistance of PV modules to any possible threats. A panel withstands 7000 Pa snow loads, according to REC Alpha 370W datasheet — much higher than a standard for PV modules.

20 year product warranty and 25 year performance warranty

Each REC 370 AA panel comes with a 20 year product warranty (25 years if installed by REC professionals) and a 25 year linear power output warranty. Check REC 370 Alpha spec sheet for more information.

Appearance matters with REC Alpha

White backsheet gives the REC panels a new look. REC 370 Alpha Black features an impressive all-black design. These PV modules make any roof stylish and pleasant to the eye.

thanks to a1solarstore for the help! they helped in sizing the system and recommended this model. The delivery was fast and we’ve just finished the installation today. it’s too early to judge on the performance, but they look amazing, sturdy, and very high-quality.

I often had my panels lose a lot of power under the sun in summer here in Phoenix. some even warp. But these ones perform amazingly! The quality makes them really worth their money.

Is it possible to get a 25 year warranty on the product?

Yes, if the system is installed by REC professionals.
hi. how fast does it degrade? what can i expect in terms of power output in like 10 years?
06/25/2021, 11:29
Hello. REC panels degradation rates are among the best in the industry. They lose a maximum of 0.25% per year, so in 10 years you can expect around 97.5%
Does it come in other sizes?

No, the dimensions are the same for all the panels in this series.
