China's Solar Energy Utilization Industry Overall Strength.
Jan 12, 2018

China's solar thermal utilization industry, no matter in scale, quantity, marketization party.

Face, still in core technology, national brand respect, are in the world leading level.

At present, the utilization of solar energy in China is mainly divided into two aspects:

(1) photovoltaic effect is used to convert sunlight radiation into electricity.

The solar cell is the semiconductor device of this kind of performance, it can turn the radiant energy of sunlight directly into electric energy, the application is very convenient, receives the extensive attention in the world.

Under the influence of international environment and the international domestic market pull, photovoltaic power generation progress rapidly in our country, the national pv cells and assembly plant for more than 10, manufacturing capacity of 100000 kw or more.

At present, China's solar photovoltaic power generation is mainly used to solve the problem of electricity consumption in remote areas.

In addition to remote areas and special areas (communications, navigation and transportation), China has also begun to undertake rooftop grid-connected photovoltaic (pv) demonstration projects.

In addition, the energy in most of the western part of our country is extremely poor, and for many years, we have worked hard to promote solar energy utilization, and have planned and planned to replace the oil and electricity.

Energy bottleneck has become the shackle of economic development and social progress in Tibet. It is the root cause of poverty and backwardness. It is no doubt that solar photovoltaic power generation is an effective way to solve this problem.

(2) use photothermal effect to convert sunlight radiation into heat energy.

Development of solar energy heat utilization technology in our country, it has already formed a relatively complete industrial system, the core of the solar-thermal industry technology leads the world level, the independent intellectual property rights rate above 95%.

As of 2006, the cumulative use of solar water heaters in China has reached 90 million m, accounting for 76% of the world's total.

By 2008, the total heating area of solar water heater in China will be 1.

With an annual production capacity of more than 25 million square meters, annual production capacity exceeds 25 million square meters, with a year-on-year growth of 10 percent, and the usage and annual output are more than half of the world's total.

The promotion of solar water heater has been basically realized commercialization, forming raw materials processing, product development, manufacturing, engineering design and marketing services industry system, led to glass, metal, insulation materials, and development of related industries, such as vacuum equipment, has become a industry rapidly expand emerging industry.
