Goldman: Solar power is the other rapidly developing industry in China as China now accounts for about 1/3 of solar power production capacity globally. The speaker refuted the view that PV cell production is an energy-ineffective process as he pointed out that the energy breakeven time is about 2 years for PV cells energy used to produce PV cells equals the energy generated by the PV cells but the normal lifetime is around 20 years. He also believes that solar energy could become commercially viable in the foreseeable future as the energy generating cost has been reduced from Rmb4 to Rmb1.1 per kWh over the past few years and is getting close to the Rmb0.3-0.4/kWh level of coal-fire power plants.
