I want to know the answer to the following question:
Where have the majority of photovoltaic power stations been built?
All the background I'm provided with is that "As of July 2012, the largest photovoltaic (PV) power plants in the world are the Agua Caliente Solar Project (USA, 247 MW), Charanka Solar Park (India, 214 MW), Golmud Solar Park". Is that enough to answer the question?
Answer: no
