The number and value of equity investment deals in the Chinese clean-energy sector in 2012 reached a six-year low, with only eight deals receiving funds of $510 million, down 82.2 percent and 48.9 percent year-on-year, respectively, a ChinaVenture Group report said on Sunday.

The report said that as the photovoltaic and wind power markets in China remained gloomy, venture capital and private equity investors did not seek deals in the sector last year.

Only five Chinese clean-energy companies got listed globally in 2012, raising funds of $99.8 million in total, down 69 percent year-on-year.

Of those five companies, three were backed by VC and PE firms, and only eight exits were made.
