In 2020, the end of the year, the voice from the 2021 National Energy Work Conference is inspiring: the main goals and tasks of the “13th Five-Year Plan” have been successfully completed, and the construction of a clean, low-carbon, safe and efficient energy system has been accelerated. “Four revolutions, one cooperation” the new energy security strategy presents a new situation with deep roots and vitality.
Looking back at the past five years, the progress of China’s energy industry has been amazing: its independent guarantee capacity has always been maintained at more than 80%, and the relationship between supply and demand has continued to improve; the total energy consumption is controlled within 5 billion tons of standard coal, and the average annual growth rate is controlled at 3 % Or less, the economic and social development and the improvement of people’s livelihood and well-being are guaranteed at a relatively low growth rate… The photovoltaic industry has also delivered a brilliant report card.
At the beginning of the “13th Five-Year Plan”, according to the scale development indicators provided by the National Energy Administration, by the end of 2020, the installed capacity of solar power is expected to reach 160 million kilowatts, and the annual power generation will reach 170 billion kWh; The proportion in the structure is about 7%, the proportion in the newly-added power installation structure is about 15%, and the proportion in the national total power generation structure is about 2.5%.
It is worth noting that the country has also put forward clear indicators for solar power technology innovation. For example, the industrial conversion efficiency of monocrystalline silicon cells, polycrystalline silicon cells, and new thin-film solar cells reach 23%, 20%, and 20% respectively.

During the 13th Five-Year Plan, China will deploy the solar power generation industry from four aspects:
1. Fully promote distributed photovoltaic power generation. Promote the comprehensive development and construction of distributed photovoltaic power generation systems in areas with construction conditions such as site, resources, nearby access, and local consumption.
2. Carry out the construction of photovoltaic power stations in an orderly manner. Focus on the western regions with good resource conditions, areas with large-scale access and local consumption capacity, combined with the planning of external transmission channels, orderly construct photovoltaic power station bases to ensure photovoltaic power consumption.
3. Actively promote the construction of solar thermal power stations. Focus on Qinghai, Gansu, Inner Mongolia and other western regions with good solar energy resources and relatively abundant unused land resources and water resources. Actively promote a number of solar thermal power station demonstration projects and build several million kilowatt-level solar thermal power generation demonstration bases.
4. Promote the utilization of solar heat. In 2020, the solar thermal utilization industry will form an industrial pattern of balanced development of manufacturing, system integration, and operation services, and a market layout dominated by civil hot water, heating and cooling, large-scale district heating, industrial and agricultural heating, etc.
During the “Thirteenth Five-Year Plan” period, China’s solar energy industry continued to make breakthroughs, intensively cultivated and innovated, and improved day by day, writing a colorful development picture:
Complete the installation target two years ahead of schedule
During the “Thirteenth Five-Year Plan” period, thanks to the continuous rapid growth of electricity load, the continuous optimization of the construction layout of renewable energy projects, and the continuous strengthening of the assessment of power grid dispatching operation, the installed scale of photovoltaic power generation has been growing rapidly, which has troubled the industry for a long time. The consumption problem of development is gradually alleviating.
According to statistics from the National Energy Administration, by the end of 2017, China’s cumulative installed capacity of photovoltaic power generation was 130 million kilowatts, achieving the “13th Five-Year Plan” guiding target for photovoltaic installation ahead of schedule. As of the end of October 2020, China’s installed photovoltaic power generation capacity has reached 228 million kilowatts, which has more than doubled the goal of the 13th Five-Year Plan. Its newly installed capacity has remained the world’s largest for eight consecutive years, significantly exceeding the industry’s expected.
At the same time, the utilization rate of photovoltaic power generation in China reached 98.3%, a year-on-year increase of 0.2%, an increase of 9% from the end of the “12th Five-Year Plan” period. The consumption situation continued to improve, providing strong support for the promotion of high-quality energy development.
From “two ends outside” to a global leader
According to industry statistics, in 2020, China’s global production capacity for polysilicon, silicon wafers, solar cells and modules will account for 69.0%, 93.7%, 77.7% and 69.2% of the global production capacity, an increase of 7.2% respectively. 4. 2.9, 4.0 and 0.9 percentage points, product production capacity and output ranked first in the world, has become one of the main driving forces for the development of the global photovoltaic industry.
With the rapid growth of installed capacity, the conversion efficiency of solar cells and modules in China’s photovoltaic industry is also constantly updating records. As of the end of 2019, the average conversion efficiency of large-scale mono-polycrystalline cells has increased by about 4 and 3 percentage points respectively compared with 2015. The average conversion efficiency of advanced cells such as heterojunction has reached 23.0%, and a number of technological innovations lead the world Industrial Development. China’s photovoltaic industry has gradually transformed from a world processing base with “two ends outside” to a global photovoltaic development and innovative manufacturing base for the entire industry chain.
In addition, during the “13th Five-Year Plan” period, China’s solar thermal power generation industry has also achieved great development. Since the National Energy Administration announced the first batch of solar thermal power generation demonstration projects in 2016, the development of China’s solar thermal power generation industry has been accelerating. As of the end of 2019, the cumulative installed capacity of 420,000 kilowatts, accounting for 6% of the world, and nearly 300 related enterprises in the industry chain. At the same time, the Delingha 50MW CSP station, one of the first demonstration projects, achieved full-load operation, and its peak shaving depth and speed were significantly better than conventional thermal power plants.
Remarkable results in helping to fight poverty
Since the implementation of photovoltaic poverty alleviation in 2015, the national level has issued five batches of special construction scales or plans for photovoltaic poverty alleviation, and has given special support to photovoltaic poverty alleviation in the management of photovoltaic power generation scale, encouraging local areas to use commercial photovoltaic indicators to build photovoltaic poverty alleviation projects for photovoltaic poverty alleviation Make full preparations for the development planning path of the project.
With the joint efforts of all regions and departments, during the “13th Five-Year Plan” period, photovoltaic poverty alleviation has achieved remarkable results. Up to now, the construction tasks of photovoltaic poverty alleviation projects have been fully completed. A total of 26.36 million kilowatts of photovoltaic poverty alleviation power stations have been built, benefiting 60,000 poor villages and 4.15 million poor households. The annual electricity fee and subsidy income can be about 18 billion yuan. Photovoltaic poverty alleviation has become a new format for poverty-stricken counties to promote industrial poverty alleviation. The important industrial support for the collective economy of poor villages to “break zero” has made important contributions to China’s advancement of the 2020 goal of comprehensive poverty alleviation.
The “14th Five-Year Plan” is approaching, and under the guidance of the “30·60” carbon development goal, the new energy industry represented by the photovoltaic industry will occupy a more important position in China’s energy structure, and provide strong support for accelerating China’s “14th Five-Year Plan” and even longer-term high-quality energy development.
