Global PV installations soared 40 percent in 2011 to 27.4 gigawatts (GW) as sluggishness in the first half of the year swung to a scramble to complete projects before incentive programs expired or get rewritten, according to NPD Solarbuzz. (That's pretty close to what European Photovoltaic Industry Association (EPIA) had earlier calculated 27.7 GW in global grid-connected PV in 2011, with six regions topping 1 GW of capacity: Italy, Germany, China, USA, France, and Japan.)
