About product


REC405AA is part of the Alpha Pure Black Series. Amazing performance of this panel is combined with improved tolerance to high temperatures and outstanding quality.

These panels have higher energy density than conventional modules — an impressive 20.3 watts/ft². Heterojunction technology (HJT) is one of the keys to achieving this success. HJT combines the best features of crystalline and thin-film silicon and shows better performance than the industry’s standard PERC cells. REC also literally packed solar cells more densely, virtually eliminating gaps. The busbars also had to leave the surface. At 21.9% efficiency, REC Alpha 405W offers surprising performance for its weight and size.

The innovations made the appearance of the REC 405 solar panel as impressive as the specs. A mere 1.2" thick, this model is completely black, without any visible busbars or gaps. This beauty doesn’t require sacrifice: the panels are lead-free and carry a reduced carbon footprint. Nor is it short-lived: REC offers 20 years of product warranty and guarantees 92% of original performance after 25 years of operation.

  • 405 W output
  • 132 half-cut heterojunction cells
  • Maximum system voltage: 1000V
  • 21.9% efficiency
  • Open circuit voltage: 46.1V
  • MC4 connectors

Higher efficiency of up to 21.9%

REC405AA guarantees the highest power output. HJT technology and potent antireflective coating result in 21.9% module efficiency. The model has a power tolerance of ±3%.

Excellent performance in adverse weather

Low temperature coefficient means greater energy production at high operating temperatures. REC 405 Alpha Pure loses just 0.26% of efficiency for every 1.8°F above 77°F.

Quality and reliability

REC 405 Alpha Pure Black receives multiple quality checks throughout the manufacturing process and is subject to stringent quality and reliability testing. The manufacturing facilities are highly automated, eliminating the risk of human error. REC is dedicated to quality, safety, and reliability to ensure you get the very best.

Reliability and degradation resistance

Slow degradation over the next 25 years is guaranteed by the manufacturer. The performance will decrease no more than 2% during the first year and then will be limited to 0.25% annually. Your modules will retain at least 92% of original performance after the 25 years are over. This 405W REC solar panel comes with a generous 20-year product warranty

A panel that can handle hail, wind and snow

The 1.2" frame made from anodized aluminum alloy and a layer of protective tempered glass make this module resistant to the foulest of weather. The front side of the modules can resist a 7000 Pa load, and the back side 4000 Pa, according to REC 405W spec sheet.

The panels were shipped by the company I trust and arrived undamaged in under a week. A1Solar are very fast, responsive and diligent. I was lucky to end up making my first equipment purchase here

Our relatives told us about A1. We’re passing on the recommendation - the store is reliable and honest. Picked the panels ourselves, so nothing to say about the delivery

Premium quality and looks, but quite expensive. If you want the best panels and super eco-frindly on top of that, look no further

Yes, we work with the top freight carriers, including R&L.
if I opt for pickup, I don’t have to pay for delivery, right?

Yes, the pickup option is absolutely free of charge.
Are 2 half-cut cells about the size of one full-sized solar cell?
