The Solar Revolution Moves on!

China Installed 31 GW Solar PV In H1/2022

by Anu Bhambhani

The China Photovoltaic Industry Association (CPIA) says during H1/2022, China installed 30.88 GW of new solar PV capacity, growing 137.4% annually over 14.1 GW reported for the same period last year (see China May Exit 2021 With Up To 65 GW New PV: CPIA).

The association counts 13.21 GW installed in Q1/2022, followed by another 17.67 GW added in Q2/2022 of the total. Cumulative installed PV capacity of the world’s largest solar market at the end of June 2022 increased to 340 GW, at the same level as wind power (see China PV News Snippets).

CPIA’s Honorary Chairman Wang Bohua said they forecast China to exit 2022 with 75 GW annual installations under a conservative scenario, and 90 GW under its optimistic scenario, which will be in any case much higher than the 54 GW installed in 2021. However, CPIA has not increased its forecast range for 2022, a level it already forecasted in Feb. 2022 (see Up To 90 GW New Solar In China In 2022). For 2023, the association predicts between 80 GW to 95 GW new installations.

Further growth can be expected during the country’s 14th Five-Year Plan (FYP) that’s supposed to run between 2021 and 2025 as 392.16 GW of total PV capacity is targeted to be installed by 25 provinces, municipalities and autonomous regions during the period. CPIA specified that in the next 4 years, 344.48 GW is to be added.

Bohua also shared an update on the Chinese plan to use its desert regions including Gobi Desert to install 97.05 GW new wind and solar capacity. It said up to now, work on more than 95 GW has been started.

The association acknowledged that the market share of large size silicon wafers has expanded rapidly with some companies having converted all their production lines to produce 182mm and 210mm sized products. However, some firms have tried to replace diamond wire process with tungsten wire which the CPIA believes is expected to further refine the wire diameter and promote thinner wafers, from 165μm to 160μm.

Even in terms of module power thanks to tenders in China, 540W+ has become the mainstream product in the market, something that even EnergyTrend also pointed at in its recent report (see 80% Chinese Producers Get 210mm Capability).

Demand for n-type products is also on the rise as n-type cell expansion projects account for 1/3rd of total expansion capacity. Announced demand for n-type modules has exceeded 4 GW, which is a 4-fold increase compared to entire 2021.

The association also reiterated solar production capacity data for H1/2022 as released by the Ministry of Industry and Information Technology (MIIT) (see China’s Solar PV Production Capacity In H1/2022).

A new Revolution in China!

 


Unnoticed, unreported, sometimes despised, the renewable revolution is coming. And, soon, it will be unstoppable. China is leading the way. 

From Taiyang news

"While the capacity it would bring online is not clear, one can safely assume it would be somewhere in the higher double digit or even 3 digit GW level. It would be a great help for the country as it makes efforts to achieve carbon neutrality before 2060"

We must do more to promote renewable energy. Otherwise, we risk losing the battle

 


Above, you can see the answer to a question about renewable energy given by the "Leonardo" AI system, one of the best available to the public. Leonardo works by parsing a huge database downloaded from the Web, searching for an answer on the basis of the popularity and the reputation of the sites it examines. So, you can see it as a special kind of search engine that will focus on a specific question and give you an answer weighed for relevance and diffusion. You can also see it as an instant "opinion poll" that tells you what the opinion leaders are thinking. 

This answer about renewables is deeply worrisome. It means that the opinion leaders believe the legend (*) that renewable energy is an appendage of fossil fuels and that it cannot stand by itself without the support of fossil energy. It confirms what you can note if you examine what is being said in the social media: a large number of "environmentalists" seem to have engaged in a personal crusade to denigrate renewables. 

In Sweden, where elections will be held in September, one of the main issues right now is the centre/right promise to build 10 new reactors and to finance the investment partly by obliging wind and solar power systems to pay an extra fee. Nobody among the proposers seems to be worried about how long it will take to build these reactors, and where the uranium needed to power them will come from. This is not just worrisome. It is a tragedy in the making. 

The problem, here, is that Leonardo (just like the general public) has no access to the data published in scientific journals, usually kept hidden behind paywalls. Which means, in practice, that Leonardo does not parse the high quality information of refereed scientific journals. The result is that Leonardo makes the same mistakes many people do, swayed by the by special interest lobbies, such as the fossil fuel industry. 

Once more, humans show their capability of shooting themselves in their feet. Governments pay huge amounts of money to scientists to develop and evaluate renewable energy technologies. Scientists give to publishers their results for free, then the publishers make these results available to the public at exorbitant fees, even thought the public has already paid for these results with their taxes. 

We have to rethink of what we are doing as scientists, researchers, and developers. It is not possible to waste so much effort because of these absurd rules, especially in a moment when renewable energy is desperately necessary in a world where the combined action of climate change and resource depletion is destroying the wealth of entire nations. 

We can't reform science in a single day, but I invite my colleagues to come down from the ivory tower and engage in informing the public about the real value and effectiveness of renewable energy. Do it. It is your duty as scientists, and as human beings. The battle is not lost, yet, but it will be if you don't engage in it.
