New Solar Gigafacotries will increase total global PV to 300GW. Using actual capacity expansion data, PV Tech's analysis indicates only 200GW of installations in 2021 will offset a period of overcapacity.

PV Tech believes 80-100 GW of old solar module technology will be retired.

Solar makers are getting huge new factories to have a price and technology advantage. They will squeeze out the smaller players.

The shift is to high-efficiency large-area monocrystalline technology shift and becoming ten times bigger than the 2-3 GW/year players.

There are also new more automated production lines in the new factories.
