Solar Energy in China Overview
As of right now, China is the world’s largest market for both photovoltaics and solar thermal energy. In addition to that, China has also been the world’s leading installer of solar photovoltaics, and in 2015, they became the world’s largest producer of photovoltaic power, just narrowly surpassing Germany. Moreover, China was the first country to pass 100 GW of cumulative installed PV capacity, and by the end of 2018, that number peaked at 174 GW.
By May 2018, China holds the record for the largest operational solar project with their 1,547-MW project at Tengger. With that said, the contribution to the total electric energy production remains modest as the average capacity factor of solar power plants is relatively low at 17%. Additionally, of the 6,412 TWh electricity that was produced in China in 2017, 118.2 Twh was generated by solar power, which is equivalent to 1.84% of total electricity production. With all these statistics, it is China’s goal to reach 1,300 GW of solar capacity by 2050. If this goal were reached, it would be the source with the largest installed capacity in China.
Aside from solar photovoltaics, solar water heating is also extensively implemented, with a total installed capacity of 290 GWth at the end of 2014. This represented about 70% of the world’s total installed solar thermal capacity.
History of Solar Energy in China
In 2007, the National Development and Reform Commission unveiled their plans to grow China’s installed solar capacity up to 1,800 MW by 2020. But in 2009, Wang Zhongying, a National Development and Reform Commission official, mentioned at a solar energy conference in Shanghai that the plan might actually be exceeded several-fold already, so the new estimation was that the installed capacity could possibly reach as much as 10 GW by 2020.
In 2010, a new feed-in tariff was introduced, and projects completed before September 30, 2012 received 1.15 yuan ($0.18) per kWh. Because of that, solar power deployment greatly exceeded initial government plans. To begin with, the 200 MW Huanghe Hydropower Golmud Solar Park was completed in 2011, which was the world’s largest solar farm at the time. Additionally, there were many other solar farms in the Golmud area, and the total installed capacity was 570 MW at the end of 2011, with another 500 MW expected in 2012. Because of that, the Qinghai province, which contains Golmud, was leading China in terms of solar installation.
Even though China seemed to be flourishing with their solar projects, the Chinese PV production system still faced severe external shocks since 2010. A sharp recession in the global demand occurred due to institutional alterations in the German market in 2010, and it was followed by anti-dumping duties and anti-subsidy countervailing duties on Chinese PV products enforced in both the U.S.A. and the E.U. Additionally, Chinese PV manufacturers, who were already running on their full capacity, faced a difficult situation in 2011 and 2012 with huge financial loses. This led to the bankruptcy of some important actors, such as SunTech Power in 2013 being defaulted on $541 million of convertible bonds.
So as to rescue the massive PV industry with its large labor market and assets, the Chinese government introduced a comprehensive set of policies, primarily to stimulate the domestic market. In other words, there was a construction of several PV power plants all over the country. As a result, the annual installed capacity in China has experienced a conspicuous growth since 2011.
In May 2011, the National People’s Congress changed the solar target again. They determined that for 2015, the official minimum PV target would be 5 GW, and for 2020, that would be around 20-30 GW. But according to a 2012 forecast by the European Photovoltaic Industry Association, that prediction was even larger and more ambitious, with the total installed capacity predicted to reach between 47 GW and 66 GW by 2017.
The solar capacity target had been upped yet again in May 2014, with 70 GW as the new target. In October 2014, China aimed to install 100 GW of solar as well as 200 GW of wind, 350 GW of hydro, and 58 GW of nuclear by 2020. Several other predictions were made starting in 2014. The first was a forecast by the market research firm NPD Group where they predicted that China would have over 100 GW of PV capacity by 2018. Then in October 2015, China’s National Energy Administration (NEA) set an ambitious 23.1 GW target for 2015, and at the same time, China planned to install 150 GW of solar power by 2020, which was an increase of 50 GW from the 2020 target that was announced on October 2014.
The goal of 105 GW that was set by the Chinese authorities for the year 2020 was passed in July 2017. In the first nine months of 2017, China installed 43 GW of solar power, thus causing the Chinese Government to more than double the original quota to 213 for 2020. With all these achievements, out of 6,412 TWh electricity that was produced in 2017, China was able to have 118.2 TWh that was generated by solar power, which is equivalent to 1.84% of the total electricity production.
Solar Photovoltaics Installation in China
Solar PV Installation by Province
A majority of the solar power capacity that is installed in China is in the form of large PV power plants that are located in the west part of the country. Most PV power plants are located on the west side, simply because this area is much less populated than the eastern part but with better solar resources and available land.
Installed Solar PV Capacity by Province
|Province||MW End of 2015||MW End of 2016||MW End of 2017||MW End of 2018|
|Tibet Autonomous Region||170||330||790||980|
Concentrated Solar Power in China
Aside from solar photovoltaics, China also has a large potential for concentrated solar power (CSP), especially in the southwestern part of the country. The highest daily mean values of direct normal radiation are usually found in the Qinghai-Tibet Plateau and Sichuan Basin, at 9 kWh/m2. Practical limitations for the deployment of CSP include mountainous terrain and distance from energy load centers, typically concentrated in the east.
According to the 12th fifth-year plan, for 2011 to 2015, an installation of 1,000 MW by 2015 and 3,000 MW of CSP plants by 2020 was announced. However, at the end of 2014, only 14 MW of CSP were functional in the country.
The following are the plants that are being planned or are under construction.
- 1 MW Badaling Pilot Project: a collaboration between the Institute of Electrical Engineering (IEE) and the Chinese Academy of Sciences (CAS)
- 12 MW (short term) / 300-MW (long term) project: a collaboration between Xinjiang Qingsong Building Materials and Chemicals (Group) Co. and Guodian Xinjiang Company

Solar Water Heating in China
China is the first country for solar water heating capacity in the world, with 290 GWth in operation at the end of 2014. That number accounted for about 70% of the total world capacity. In terms of capacity per unit of population, China ranks 7th in the world with 213 kWh per 1,000 people. Most of the installed capacity (92%) was evacuated tube water heaters.
The Future of Solar Energy in China
According to a new study, solar power now costs the same as or less than, electricity from the grid in many of China’s cities. It’s true that as of right now, most of the country’s electricity comes from coal, but China is still aggressively pursuing renewable energy. In fact, the U.S. Energy Information Administration projects that China’s solar capacity will grow more than 7% per year from 2015 to 2040.
It helps that advances in solar technology have helped bring solar within reach of grid parity sooner than expected in China. Before, the cost of solar photovoltaic electricity was up to 15.1 yuan per kilowatt-hour in 2000. But in 2018, it was only 0.79 yuan per kilowatt-hour. Additionally, in 2018, the Chinese government dramatically cut subsidies to the solar PV industry so as to drive it to compete with coal without government aid.
All of these statistics are pointing to the possibility of a bright future of solar energy in China. In addition to that, future research could explore how commercial and industrial solar power customers in China might benefit as grid energy storage comes down.
Solar Manufacturers in China
With all of their contributions to the solar industry, China became the world’s largest manufacturer of solar products and has been since 2008. And since 2011, the country has produced the majority of global photovoltaics on an annual basis. In fact, industry projects estimated that, by the end of 2017, China would have enough manufacturing capacity to produce 51 GW of PV modules per year. This amount is over twice as large as 2010’s global production of 24 GW.
Considering that China dominates the solar industry in terms of manufacturing products, there are all kinds of manufacturers for all kinds of solar PV products. The following are only some of the manufacturers per a particular kind of solar product.
