REC group unveiled the new Alpha panels with an impressive 21.7% peak efficiency. The Alpha series use advanced heterojunction (HJT) cells in a half-cut 120 cell format to deliver an impressive 380Wp
Sunpower has been selling 22% efficiency panels for quite some time now. Shows you how advanced sunpower is compared to everyone else. But they too have reached a peak. I don't see a 23% from them or anyone else.
Yes SunPower has been leading the market with the more advanced IBC cells but's it's amazing how far the HJC cells technology has developed. The competition is really heating up.
