  • Editors choice 2022 (REC Solar range).

Pure by name, pure by nature. The REC Alpha Pure is the next-generation solar module derived from the Intersolar award-winning REC Alpha series. More refined, improved power density, outstanding temperature coefficient and most interestingly, the absence of toxic lead componentry influencing the name “Pure”.

Model:  

REC Alpha Pure.

Variants:

Alpha Pure; 385 / 390 / 395 / 400 / 405 / 410 W. 

TLDR: 

Not the first HJT solar module created. However, the REC Alpha Pure (descended from the REC Alpha series 2019) is potentially the most influential. Refining an already impeccable design that further enhances Efficiency characteristics, the REC Alpha Pure series earns a Solar Analytica Editors Choice Award for 2022 as a superior product within the industry.

Features: 

HJT (Heterojunction Technology), Extreme positive & negative loading, Outstanding temperature coefficient.
