China's quiet achiever makes mark on energy's new frontier - WAToday.au | ... Miao, 57, is much less famous outside China, though perhaps not for much longer. His company, Yingli Green Energy, has knocked Suntech off its rank as the world's biggest producer of solar photovoltaic panels and its breakneck growth - along with an array of other Chinese firms - has driven PV prices down by about three-quarters in four years. ...Partly because of its flexibility, Yingli has continued to produce at its capacity of about 2.5 gigawatts of cells a year. June quarter shipments were about 23 per cent higher than the first quarter, a growth pace roughly double earlier estimates. Significantly, Yingli has turned to its domestic market to maintain growth. Shipments to Chinese customers accounted for 23 per cent of output in the second quarter, up from 6 per cent a year earlier.The opening of the Sydney office is also part of Yingli's search for new markets. The company aims to grab 10 per cent of the Australian market within a couple of years, with a focus on commercial customers. Orders secured include a 1.25-megawatt deal to supply the panels for 30 buildings for the City of Sydney worth $3.4 million, while it has also signed a distribution pact with L&H Group, a major electrical wholesaler in Australia and New Zealand.
