R & D Input Chinese government has been increasing
R&D support to renewable energy industry Main programmes: Key Research Program,
863 program, 973 program, Natural Science Foundation
R&D input （￥ to Rs times 5.2 ） 7th five-year (1985-89): ￥ 30 million 8th five-year (1990-95): ￥ 30 million 9th five-year (1996-00): ￥ 60 million 10th five-years (2001-05): ￥ 220 million
15
Financial support From 1987 to 1997, ￥ 120 million per year
technical innovation loan to support renewable energy industries
In 2002, ￥ 175 million technical innovation loan further allocated to the production lines upgrading solar industries
Financial support also available from local governments
In 2007, National Reform and Planning Commission launched a “bright project” with ￥ 10 billion to application of PV power
16
Promote standardization and legislation
The standard systems set up for solar water heater
Standard system for solar water heater, including
16 national technical standards and 3 industrial
standards
All production in solar water heaters are
standardized consistent to the standard systems
17
Promote standardization and legislation
Setting up a solar water heater quality monitoring and authentication system Three quality monitoring centers set up in Beijing,
Wuhan and Kunming
An authentication center set up in Beijing by 2004
Legislation On 28 February 2005 China released the Renewable
Energy Act, enforcing from 1 January 2006

China’s Long-Term Plan for Renewable Energies up to 2020 On the day of 4
September 2007, China released a plan for next 13 years of renewable energies up to 2020
By 2010 renewable energies 10% of total consumption; by 2020 reaches 15%
2010 2020
Hydro power
190 GW 300 GW
Bio- power
5.5 GW 30 GW
Windpower
5 GW 30 GW
Solarpower
0.5 GW 1.8 GW
Solar is more expensive, still 7 times higher than coal power

Solar Market Development Combination of solar energy in
building industry China’s building and real estate
industries in fast moving, annual building completion area 200 million m2
Goal: contributing 6.5% of energy consumption of buildings
Many cities in China launched scheme of “solar hotwater for million houses”
21
Solar Market Development
Rural areas, a huge market for solar energy utilization in 2000, total housing area 17 billion m2 in 2020, total housing area 26 billion m2
Rural housing is scattered in a vast areas, traditional energy (coal, electricity, natural gas), not technically and economically efficient
But a great potential for solar energy in rural areas where there is no access to electricity and natural gas
22
Solar Market Development
Toward remote areas: Solar power station for telecommunication Solar power unit for satellite ground stations Solar power pumps Solar power station for schools Solar power unit for individual farmer
households Solar power unit for frontier military posts
23
Technology Development Treads Integration of solar energy
in buildings Solar lights Solar city demo in Baoding Solar energy sea water
desalination Solar drying technique and
its application Medium and high
temperature utilization (thermal power generation)
