There is no "possibly" about it. Right now, solar is the cheapest form of electrical generation ever, in human history, and it is still getting cheaper. It has literally seen price drops of more than 2 orders of magnitude in my lifetime. It is, without a doubt, going to be the primary means of energy generation for the future of our species, assuming our species is to have a future.
It's hardly something the Chinese can claim as their achievement, though. There's a large economy for solar panels -- and frankly, the Chinese production ramped up in response significantly to Californian demand under their (now besieged) rooftop solar policies. A lot of players are involved from research to production to demand and any one country that claims it's all thanks to them is sweet-talking you.
