High Power Output & Efficiency

450W nominal power (up to 470W in higher watt-class sorting)
21.6% module efficiency (up to 22.6% in top bin)
Exceptional power density of 21 W/ft² (226 W/m²) — ideal for maximizing energy yield on smaller or constrained roofs
88 half-cut bifacial HJT cells with innovative gapless layout that increases active cell area and boosts overall output

The REC Alpha Pure-RX produces more power per square foot than most residential panels, making it one of the highest-performing 450W solar panels available today.

Advanced Heterojunction (HJT) Technology
REC’s cutting-edge HJT cell technology eliminates Light-Induced Degradation (LID) and offers excellent temperature performance with a low temperature coefficient of -0.24%/°C. This means the panel maintains higher output in hot climates and delivers consistent, reliable energy production year after year.
Additional benefits include:

Solder-free cell connections that reduce the risk of microcracks and improve long-term durability
Increased number of thin, barely-visible wires for better current flow and higher efficiency
Enhanced low-light and shade tolerance thanks to the advanced four-section Twin design layout

Sleek All-Black Design & Robust Construction
The REC450AA features a premium full-black (BLK/BLK) appearance that appeals to homeowners prioritizing curb appeal. Its slim 30mm black anodized aluminum frame is lightweight yet extremely strong, making the panel easier to handle during installation.
Built to withstand extreme weather:

Snow load up to 7000 Pa (with 4-point clamping) or 10000 Pa (with 6-point clamping)
Wind and hail resistance rated for demanding environments
1000V maximum system voltage with MC4-compatible connectors

Industry-Leading Warranty Protection
REC stands behind the Alpha Pure-RX with confidence:

20-year Product Warranty — covers manufacturing defects
25-year Performance Warranty — guarantees at least 92% of nameplate power in year 25, with a low annual degradation rate of just 0.25%

When installed by a REC Certified Solar Professional, the panel qualifies for the REC ProTrust Warranty program, which extends coverage to include 25 years of product, performance, and labor protection — offering unmatched peace of mind.
