Singapore-based solar manufacturer REC Group has launched the fourth generation of its TwinPeak premium panels for residential and commercial rooftops, including a new cell structure design and higher power output.
REC said this week that the TwinPeak 4 Series, with a nominal output of up to 375W-peak, had gone into production this month, with deliveries expected from July and August onwards.
The company said the new panel series would offer the choice of white or black backsheet variants, multi-busbar connection, improved power output from 120 half-cut monocrystalline p-type cells, and a “best-in-class” performance in tough rooftop conditions, including partial shading.
The new panels also come with extra support bars across the rear, boosting their strength and durability and helping to achieve much higher energy yields. 
REC Group vice president of global marketing and product management, Cemil Seber, said the new panels improved on the strengths that had made the TwinPeak family “such a success,” including the pioneering and award-winning Twin Design.
The first TwinPeak generation, launched in 2014, was the first to feature REC’s patented split cell and junction box technology and won the Intersolar Award 2015.
“The REC TwinPeak 4 marks the latest advancement in technology and performance for our TwinPeak family, and strengthens the entire REC Group portfolio by giving more options to our rooftop customers, be it in the residential or commercial and industrial segments,” Seber said.
The TwinPeak 4 Series is also eligible for REC’s comprehensive ProTrust warranty package, including 25-year warranty on the product, performance and labour, subject to conditions.
The new panels also come with an improved power warranty of just 2 per cent maximum power degradation in the first year of operation and 0.5 percent per year thereafter until year 25.
