Europe dominated new solar power installations last year, at about 13 gigawatts (GW), Masson estimated, with Germany and Italy accounting for nearly 7 GW and about 3 GW respectively.

Portal venous velocity index (PVI) was defined as the ratio of PVV to graft weight (GW), and portal flow volume index (PFI) as the ratio of PVF to GW.

World solar cell production reached a consolidated figure of 9.34 GW in 2009, up from 6.85 GW a year earlier, with thin film production accounting for 18% of that total.
