Czechs cut solar feed-in tariffs by 5 pct for 2010

* Deeper reductions possible

* New tariffs include "green bonus"

PRAGUE, Nov 25 (Reuters) - The Czech energy regulator has cut feed-in tariffs for solar-generated power by 5 percent from the beginning of 2010, the country's energy regulator announced on Wednesday.

Generators who produce solar energy sold to any of the country's three main power distributors will receive 12,250 Czech crowns ($709.3) per megawatt hour, down from 12,890 crowns per MWH in 2009, according to the Energy Regulatory Office.

The new tariffs also include a so-called "green bonus" of 11,280 crowns per MWH for solar power sold to traders or other customers, down from a current price of 11,910 crowns per MWH, the office said.

Tariffs are the solar industry's lifeblood as long as the so-called grid parity -- the point at which renewables cost the same as fossil fuel-based power -- has not been reached.

Investors are on the lookout for new opportunities in central and southeastern Europe after Spain and Germany, the global industry leaders in photovoltaics (PV) that turn sunlight into energy, have either cut or plan to curtail incentives.

The Czech Republic has so far attracted the lion's share of investment in eastern Europe due to generous subsidies but investors are worried Prague may reduce the feed-in tariffs even further.
