Thin-film solar module manufacturer, First Solar topped the rankings list for PV module suppliers in 2009, surpassing all of its crystalline rivals to ship more than a gigawatt (GW) of modules and become the industry's largest supplier, according to the latest analysis from IMS Research.

Although 7.5 GW of installations were completed and connected in 2009, IMS Research estimates that shipments of PV modules were far higher.
