Details here, 21,520 and 20,480, seem 232W avg first farm the other 244W between 14.2 and 15% efficiency,

Article points to 15.8% average but this is the module they are quoting

Friends from REC when I had an interview sent me this pdf (attached) about their Peak modules the ones with 15.8% efficiency Interestingly REC module is larger by about 2.5 cm from Virtus II and that causes a loss of 0.2% efficiency. However this output is about 197 of nominal power vs. 193 in Virtus II
