pv magazine has published a background report on the surge of monocrystalline technology, driven by the two leading Chinese mono wafer manufacturers Longi and Zhonghuan Semiconductor.

Quoting independent analyst Corrine Lin, the report says that monocrystalline technology made up 28% of global wafer supply in 2017 whereas the share in China is estimated at 40%, which would be equivalent to approx. 21 GW of mono products. This amount can only in part be explained by China’s “Top Runner” program for installations with high-efficiency modules as its 2017 target was only 5.5 GW.

The forecasts for the global mono share in 2018 vary:

If the overall PV market does not grow strongly enough, a price war between mono and multicrystalline technologies is likely.
