Sydney, AUSTRALIA – 14 September 2023 – REC Group, an international pioneering solar energy company, announced today that it has launched its latest high-efficiency solar panel innovation, the REC Alpha Pure-RX. Reaching 470 Wp, the REC Alpha Pure-RX is the company’s highest power residential panel produced in the Alpha Pure family of solar panels.
Based on the advanced heterojunction cell technology (HJT), REC continues to enable customers to maximise the output of rooftop installations. With an increased power density of 226 W/m² or 21 W/ft2, the REC Alpha Pure-RX is REC’s fourth product innovation based on its Alpha HJT technology and exemplifies REC’s mastery of HJT, since it was launched in 2019.
Continuing with REC’s commitment towards innovation, the REC Alpha Pure-R and the Pure-RX panels are based on large G12 HJT cells in a gapless half-cut cell design for improved aesthetics and increased power of 40 Wp. These panels are lead-free and RoHS compliant for higher sustainability.
Mastering HJT
“While many solar panel manufacturers have moved to TOPCon as a quick and simple successor to PERC technology to offer some incremental efficiency gains, REC stays committed to HJT as the real pioneering technology, presenting the biggest potential for efficiency leaps in the near future. We at REC believe that HJT is also the best option for future developments like tandem structures. While most manufacturers will likely follow that route at some point, REC has already a strong track record of manufacturing HJT solar panels,” says Jan Enno Bicker, CEO at REC Group.
As the solar industry races towards larger wafers for higher efficiencies, it faces challenges of switching to G12 large wafers and cells on HJT. A crucial enabler to overcome this challenge in REC’s Alpha Pure-R and Pure-RX HJT panels is AMI – Advanced Module Interconnection. This innovative solder-free foil and wire combination enables REC to further master the advanced HJT technology and to achieve higher throughputs.
Protecting customers and the environment
While most of today’s TOPCon solar panels come with a degradation of 0.4% per year and 89% power at year 25, REC’s Alpha HJT products, including the new REC Alpha Pure-RX, guarantee at least 92% power output after 25 years, giving consumers and installers greater peace of mind. At the same time, manufacturing these solar panels allow REC to reduce resource consumption and waste disposal, providing greater protection for the environment in the long-term.
In line with REC’s mission to combine high-efficiency innovations with sustainable manufacturing practices, REC has eliminated lead from the new REC Alpha Pure-RX, making the panel RoHS compliant and ultimately contributing towards a better environmental protection. “From a pure manufacturing and cost perspective, lead in soldering is making the production easier,” explains Shankar G. Sridhara, Chief Technology Officer at REC Group. “However, getting rid of lead in solar panels simplifies the recycling of solar panels at their end of life and it is worth going the extra mile.”
Production of the REC Alpha Pure-RX is set to commence in January 2024 at REC’s Industry 4.0 manufacturing facility in Singapore and it is expected to be available in Australia and New Zealand in Q1/2024.
