MNRE clarifies in respect of domestically manufactured solar PV cells

MNRE clarifies in respect of domestically manufactured solar PV cells

Decision expected to give boost to domestic manufacturing of solar cells in India

New Delhi, 21st October, 2019

In a major decision that is likely to give further boost to domestic manufacturing of solar cells in India, MNRE has issued a clarification in respect of domestically manufactured solar PV cell today.

It may be noted that a number of flagship programmes of MNRE such as KUSUM, have provisions for mandatory use of domestically manufactured solar PV cells. However it was seen that some manufacturers have been importing semi –processed solar PV cells (generally called blue wafer) and making final Solar PV cells with little value addition in India.

The Ministry has clarified that if diffused silicon wafer (generally called ‘Blue Wafer’) is imported and the same is used as raw material for the manufacture of solar PV cells in India, such solar PV cells shall not qualify as domestically manufactured solar PV cells, for the purpose of MNRE’s Schemes / Programmes. A solar PV cell shall be considered to be domestically manufactured only if the same has been manufactured in India, using undiffused silicon wafer (generally called ‘Black Wafer’).

It is expected that this decision will help in establishing a strong solar manufacturing base in India.

The order issued by MNRE in this regard is as below –

This is in reference to the schemes/ programmes being implemented by the Ministry of New & Renewable Energy, wherein it is mandatory to use domestically manufactured solar PV cells and domestically manufactured solar PV modules, and also in reference to the Manufacturing-Linked-PPA initiative by Solar Energy Corporation of India Ltd (SECI).

  1. A solar PV cell shall be considered to be domestically manufactured only if the same has been manufactured in India, using undiffused silicon wafer (generally called ‘Black Wafer’), classifiable under Customs Tariff Head 3818 and all steps / processes required for manufacturing solar PV cell from the undiffused silicon wafer have been carried out in India.
  2. If diffused silicon wafer (generally called ‘Blue Wafer’) is imported and the same is used as raw material for the manufacture of solar PV cells in India, such solar PV cells shall not qualify as domestically manufactured solar PV cells, for the purpose of MNRE’s Schemes / Programmes mandating use of domestically manufactured solar PV cells.
  3. The solar PV cell manufacturing facility required to be set-up under SECI’s Manufacturing-Linked-PPA initiative should manufacture solar PV cells from undiffused wafers, as explained above.
  4. This issues with the approval of Secretary, MNRE.”

Renewables in Ukraine – July 2019


Ukraine’s Renewables Investment Boom

The Ukrainian government has committed to increase renewables from around 4 per cent of the energy mix today, to 25 per cent by 2035.

While hydropower dominates the country’s renewable capacity, averaging 4.6GWp over the last decade, installed wind, solar and bio energy capacity increased by 54 per cent to 2.1GWp in 2018 alone, with a further 4.6GWp of capacity in the pipeline.

Much of this growth and pipeline, particularly in wind and solar, has been fuelled by a rush to secure the Green Tariff, which will be replaced by an auction-based regime from 2020.

Introduced in 2008, the Green Tariff provides highly attractive and guaranteed Euro-denominated rates until the end of 2029. Investors can still secure the Green Tariff provided that projects have obtained land use rights, a grid connection agreement, a construction permit and a power purchase agreement (PPA) in the new format by 31 December 2019.

Passing of Ukraine’s Auction Law for alternative energy sources in April 2019 follows a well-trodden path. Use of auctions to manage supply to a national grid has become commonplace in recent years.

According to research by the International Renewable Energy Agency (IRENA) the number of countries that have adopted renewable energy auctions increased from six in 2005 to more than 67 by early 2017, and continues to rise.

Although the auction regime will undoubtedly lower returns on investment, compared to those offered by the Green Tariff, any reductions should be manageable, subject to the capacity offered at each auction, as advances in technology continue to reduce generating costs.

We expect the investment climate for Ukrainian renewables to remain favourable. Indeed, the government’s 2035 energy mix target will require significant, and sustained investment in new renewable capacity, storage and transmission networks.

Overall, the outlook for the renewables sector in Ukraine looks bright. Development of the sector has been rapid in recent years, and will continue in the years ahead, although investors should carefully assess the impact of the new auction regime.

Yingli in talks with creditors over break up

Chinese solar panel manufacturer Yingli this morning revealed it is talks with its lenders about a potential takeover of its chief Chinese business units.

Yingli Green Energy Holding Company Limited today revealed on its Yingli Solar website that the extent of its debts means its lenders may take control of the parent company’s Chinese subsidiaries or those units may instead be acquired by “strategic investors”.

pv magazine has been aware of rumors the major solar manufacturer could be acquired by the state-owned China Development Bank since the SNEC trade show in March but had been unable to substantiate the lead.

Today’s announcement was light on detail and did not identify monies owed, creditors or potential state-backed white knight investors. The statement did outline, however: “The company understands that various parties including relevant governmental agencies are making concerted efforts to promote the debt restructuring of the company’s major PRC [People’s Republic of China] subsidiaries.”

Yingli’s 2018 annual report, published in May, outlined the extent of the company’s financial distress and acknowledged the manufacturer faced being broken up to satisfy creditors.

Debt mountain

A Form 20-F filing lodged with the U.S. Securities and Exchange Commission revealed Yingli’s Baoding Tianwei subsidiary had overdue medium-term notes worth RMB4.45 billion ($628 million). According to the filing, parent company Yingli Green Energy Holding had a capital deficit of RMB11.9 billion at that point, overdue short-term borrowings of RMB4.77 billion, had been unable to roll over RMB2.39 billion of debts due to fall in April and May and had another RMB8 billion due by May 2020.

On top of that, three creditors had secured court victories relating to a total RMB468.4 million owed them with a further RMB110 million being contested in the courts and the company had just received a claim for a further RMB106 million.

The business was de-listed from the New York Stock Exchange in July 2018.

Today’s announcement did not name the Chinese subsidiaries which may pass to new ownership but known mainland units of the Baoding-based manufacturer include: Baoding Tianwei Yingli New Energy Resources Co Ltd; Tibet Keguang Industries and Trading Co Ltd; Lixian Yingli New Energy Resources Co Ltd; Tibet Tianwei Yingli New Energy Resources Co Ltd; Jiangsu Yingli New Energy Co Ltd; Chengdu Yingli New Energy Resources Co Ltd; Baoding Zhongtai New Energy Resources Co Ltd; Xinjiang Yingli New Energy Resources Co Ltd; Yingli Energy (Beijing) Co Ltd; Tianjin Yingli New Energy Resources Co Ltd; and Yingli Green Energy Hong Kong Trading Limited.
