REC Solar
Pioneering solar innovation since 1996. Alpha Series HJT cells deliver 22.3% efficiency with the industry's lowest degradation and strongest warranty, backed by the REC ProTrust guarantee.
Premium Panels, Unmatched Warranty
REC Group is a Norwegian-founded solar energy company that has been at the forefront of solar innovation for nearly three decades. Their Alpha Series panels, featuring advanced heterojunction cell technology, consistently rank among the highest-efficiency and lowest-degradation residential panels available. Combined with the industry-exclusive ProTrust warranty program, REC delivers the strongest total value proposition in the premium solar panel segment.
Alpha Series HJT Cell Technology
REC Alpha Series panels use heterojunction (HJT) cells, a premium cell technology that combines crystalline silicon wafers with ultra-thin amorphous silicon layers deposited on both sides. This dual-sided passivation creates the most efficient light-to-electricity conversion available in mass-production solar panels. The HJT architecture delivers a remarkable 22.3% module efficiency, placing REC Alpha among the highest-efficiency residential panels in the world. Unlike conventional PERC cells, HJT cells have a symmetrical structure that enables true bifacial energy capture.
Industry-Lowest Degradation
REC Alpha panels exhibit the lowest degradation rates in the residential solar market, losing just 0.25% per year after an initial first-year degradation of only 1%. Compare this to conventional PERC panels that typically degrade at 0.5% or more per year. Over a 25-year system lifetime, this superior degradation performance translates to approximately 10% more cumulative energy production than a comparable PERC panel. REC backs this claim with a linear power output warranty guaranteeing at least 92% of rated power at year 25, the strongest degradation guarantee available on residential solar panels.
REC ProTrust Warranty Program
The REC ProTrust warranty is the most comprehensive panel warranty available in the residential solar industry. Available exclusively through REC Certified Solar Professional installers like ProGreen Solar, ProTrust extends the standard 25-year product warranty to include labor coverage for any warranty claim. This means if your panel ever needs to be replaced under warranty, REC covers not just the replacement panel but also the labor cost for the technician to remove the old panel and install the new one, a benefit worth hundreds of dollars that most panel warranties explicitly exclude.
Norwegian Innovation Heritage
Founded in Norway in 1996, REC has nearly three decades of experience pioneering solar technology innovations. Their vertically integrated approach spans from polysilicon production through cell manufacturing to module assembly, giving them complete control over quality at every stage. REC panels are manufactured in their state-of-the-art facility in Singapore, which is one of the most advanced and automated solar panel factories in the world. Every panel undergoes rigorous quality testing including electroluminescence imaging, flash testing, and visual inspection before earning the REC name.
REC Panel Series
REC offers two distinct panel series for residential installations: the premium Alpha Pure-R with industry-leading HJT technology, and the value-oriented TwinPeak series with excellent PERC performance. Both series qualify for the comprehensive ProTrust warranty when installed by ProGreen Solar.
REC Alpha Pure-R Series
The REC Alpha Pure-R is the latest evolution of REC's award-winning Alpha Series, representing the absolute pinnacle of residential solar panel technology. Building on the proven heterojunction cell platform, the Pure-R adds lead-free cell interconnection and a fully recyclable design philosophy, making it one of the most environmentally responsible high-performance panels available. With up to 430 watts of power and 22.3% module efficiency, the Alpha Pure-R delivers exceptional energy output from a compact residential form factor.
The Pure-R uses 132 half-cut HJT cells in a patented split-junction design that divides the panel into multiple independent cell strings. This architecture provides extraordinary shade tolerance, maintaining high output even when portions of the panel are shaded by chimneys, vents, or nearby structures. The HJT cells feature an exceptionally low temperature coefficient of -0.26% per degree Celsius, meaning the Alpha Pure-R retains more power in hot conditions than virtually any PERC-based competitor.
REC's commitment to quality is evident in every detail of the Alpha Pure-R. The panel features twin junction boxes for improved reliability, a reinforced frame rated for extreme wind and snow loads, and REC's signature black frame with white backsheet aesthetic. Every panel is individually flash-tested and EL-imaged at the factory, with a positive-only power tolerance of 0 to +5 watts ensuring you always get at least the rated power output.
