FRANKFURT/MADRID, Nov 12 (Reuters) - European renewable companies posted moderate to sharp declines in quarterly results but sounded more upbeat for 2010, as costs cuts and an expected pickup in demand help lift profits after a year of turmoil.

Three of Germany's top solar energy companies said they expected to either return to or grow profits next year following a year of weak economic demand, reduced government subsidies and bruising price competition from low-cost Asian rivals.

The two biggest -- Q-Cells (QCEG.DE), among the world's largest solar cell makers, and Conergy (CGYG.DE) -- aim for a 2010 operating profit [ID:nWEA0568].

Still, both companies posted large quarterly net losses, with Q-Cells, a supplier of cells and module components to commercial customers, losing nearly a quarter of a billion euros. [ID:nLB153099], [ID:nWEA0668]

Solar equipment wholesaler Phoenix Solar (PS4G.DE), which like Conergy, installs residential solar roof panels, posted a small third-quarter net profit, but cut its 2009 outlook due to delays in the financing of solar power plants. [ID:nWEA0591]

Spanish wind turbine maker Gamesa (GAM.MC) posted a 21 percent fall in nine-months core profit from a year earlier, but said that its activity should pick up in the fourth quarter of 2009 and plans to launch new products in 2010

Investors will have to wait until February for a 2010 outlook for Gamesa, which was optimistic about the Spanish business environment in 2010 thanks to new renwables regulation, but did not see a recovery at its US business in the short term.
