REC

REC Group is a residential solar manufacturer whose Alpha Pure-R line uses a heterojunction cell and a gapless panel design. The line targets homeowners who want high efficiency and low degradation.

The REC Alpha Pure-R is REC's residential flagship in the United States. It delivers high module efficiency with a slow warranted degradation rate. REC pairs it with a separate product and performance warranty.

Efficiency and Power Output

The REC Alpha Pure-R reaches a maximum module efficiency of 22.3 percent. REC builds the panel on heterojunction cell technology to raise conversion efficiency. The design packs more power into a residential module.

REC rates the Alpha Pure-R across a power range of 400 to 430 watts peak. That range gives installers flexibility across roof sizes. The top of the range suits homeowners who want higher output per panel.

Degradation and Warranty

REC warrants an annual degradation rate of 0.25 percent for the Alpha Pure-R. The panel is warranted to still produce at least 92 percent of its nameplate power in year 25. That slow decline supports long-term energy yield.

The Alpha Pure-R carries a 20-year product warranty and a 25-year performance warranty. The product warranty covers panel defects while the performance warranty covers output. Homeowners get separate protection for hardware and production.
