Solar build-out: a gigawatt a year in 2004, one a day now

So what

Global solar capacity has grown two-thousand-fold since 2000 to about 2,400 GW, and the world now adds more than a gigawatt every day. China owns half of the installed base, which also gives it the scale advantage on the learning curve. For utilities, grid operators and equipment makers, the planning question is no longer whether solar scales but how to absorb it: storage, transmission and curtailment.
