The TaiyangNews PV Price Index pivoted sharply to the positive in Calendar Week 29, with most upstream products seeing double-digit increases, apparently as a result of the MIIT calling for curbing ‘disorderly and low-price competition’.

With MIIT’s call for an end to low-price competition earlier this month, the days of rock-bottom prices seem to be over. With the price increases in Calendar Week 29, the polysilicon category has moved into positive territory YtD, while n-type wafers, cells, and modules are staging a turnaround. On the other hand, the gradual phase-out of p-type products continues.

The data refers to average product prices in China. The data was collected by Chinese market research firm Gessey PV Consulting.
