REC Alpha Pure-R Series Benifits

Greater Yields From Dawn to Dusk

The REC Alpha Pure-R packs in more energy than ever before. With no LID, a leading temperature coefficient and its high power density, it is ideal for increasing energy yields and making the most of available rooftop space.

RECs 25+ year Warranty

Pioneering Panel Designs

REC's award-winning and iconic Twin design splits the REC Alpha Pure into two ‘Twin’ sections which aids in reducing internal resistance leading to more power and increased reliability. Continued energy production in shaded conditions means you see higher energy yields & REC Alpha Pure-R takes this further and divides the panel into four sections, producing even more energy in shade

REC improved performance in shade

More about the new REC Pure-R Series Panels

Leading the way

Leading The Way To a more Sustainable Future

Lead and other toxins can be found in almost all solar panels today. That means all the panels produced in 2021 will potentially add around 11,000 tons of lead to the environment in the future! Using advanced manufacturing techniques, the REC Alpha Pure has removed the lead from all components so that it is compliant with Restriction of Hazardous Substances regulations (RoHS) across the world. This sets the pace in sustainability for solar and shows that a clean energy future without lead and toxins is possible.

Leading the way

Maximize System Power For Maximum Savings

Optimum use of space is key to a good solar installation. The REC Alpha Pure-R allows you to pack in as much power as possible, generating more energy and more savings on your bills. The comparison is clear: in a regular residential installation, the REC Alpha Pure-R offers more power than conventional panels for more energy and more savings.
