Each module is rated by its output power under standard test conditions (STC) and hence the on field output power might vary. Power typically ranges from 100 to 365 (W). The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 W module will have twice the area of a 16% efficient 230 W module. Some commercially available. China, Vietnam, Malaysia, and India manufacture 89% of the world's solar panels between them – and Asia's contribution to the industry doesn't stop there. [pdf]
