Solar power boom poses a distribution challenge

By Dat Nguyen   January 5, 2021 | 08:31 pm GMT+7 vnexpressSolar power boom poses a distribution challengeA worker installs solar power panels in Ninh Thuan Province, central Vietnam. Photo by VnExpress/Quynh Tran.The increasing solar power capacity has made it difficult for national utility Vietnam Electricity (EVN) to ensure stable power distribution nationwide.

The nature of solar power capacity, which accounts for 25 percent of the total, is to produce high volumes during the day and no production in the evening. This poses difficulties for EVN in operating the national grid, the national utility has said in a report.

There have been times when the grid was oversupplied during the low-demand hours between 10 a.m. and 2 p.m. when solar radiation is at peak, the report says.

On the contrary, when power demand is at the highest, the 5:30-6:30 p.m. period, solar power production falls to nearly zero and the traditional power generators have to be mobilized.

“The ratio of renewable power generation is increasing and with it comes instability in operation,” the report says.

Vietnam’s solar power capacity was roughly 16,500 megawatt by the end of last year, nearly 48 percent of it coming from rooftop panels and the rest from plants.

Solar power production reached 10.6 billion kilowatt-hours last year, accounting for 4.3 percent of total.

There was a surge in the number of solar power projects after the government offered an incentive feed-in tariff scheme to promote renewable energy production to meet rising demand in a fast-growing economy.

Determining how many years a solar panel will last can take, well, years. Intended to function for 25 years or more, solar panels must be made to withstand the elements. In some cases, panels continue working well after their planned operational lifetime. Nowhere is this more evident than on the sunny hillside in Golden, Colorado, where the National Renewable Energy Laboratory (NREL) operates the Outdoor Test Facility (OTF).

Database for emerging PV technologies

emerging-pv.org 

Aiming to complement NREL’s Best Research-Cell Efficiency Chart and the Solar cells efficiency tables by Martin Green et al., which list the absolute best performing certified efficiencies for each major photovoltaic (PV) technology, emerging PV reports provides an alternative reference. We summarize the best results in the PV research, as published in academic journals (certified and uncertified) and with respect to the Shockley-Queisser efficiency limit, encouraging the reproducibility of the results. Unlike the established overviews, our new approach also deals with the best flexible, transparent/semitransparent and long-term photostable PV devices. In all cases, we also suggest protocols for best practices in characterization and reporting of emerging PV device performance.

Solar power investors fear they may not be able to enjoy preferential FIT

27/08/2020    08:58 GMT+7 vietnamnet

Covid-19 and the slow implementation of power transmission projects may make it impossible for solar power projects to connect to the national grid by the end of the year.

Investors of solar power projects are concerned that they may fail to connect to the national grid and this be able to enjoy the preferential FIT (feed in tariff) of 7.09 cent per kwh.

Solar power investors fear they may not be able to enjoy preferential FIT

Under current regulations, the price is only applied to projects which become operational and connect to the national grid no later than December 31, 2020.

Over 45,000 households and organizations in the country have installed rooftop solar panels, whose prices have been falling rapidly in recent years.

Le Anh Tuan, lecturer at Can Tho University in southern Can Tho City, spent VND130 million ($5,600) to install a 3.9 kWp rooftop solar power system in his home four years ago and is now enjoying the fruits of his investment.

Tuan was able to save up to VND1.2 million each month compared to using normal electricity, twice the amount of monthly deposit interests.

Phát triển ngành Năng Lượng Việt Nam: Góc nhìn chiến lược

T.S Đào Thu Hằng

Tóm lược

Bài báo đóng góp những kiến nghị để cải tiến và đổi mới ngành năng lượng và giao thông của Việt Nam, hai lĩnh vực nhìn chung được coi quan trọng nhất đối với các chính sách về năng lượng và khí hậu.

Trong nhiều năm, Việt Nam vẫn đi sau thế giới về năng lượng tái tạo – đặc biệt là điện gió, điện mặt trời, và hiệu quả năng lượng, và phần lớn dựa vào than và dầu. Việt Nam định ra cho ngành năng lượng một phần rất nhỏ trong Đóng góp quốc gia tự quyết định (Nationally Determined Contribution – NDC) để giảm thiểu phát thải carbon, mặc dù ngành năng lượng chiếm đến một nửa lượng khí thải của quốc gia, và điều này gần như loại trừ hoàn toàn ngành công nghiệp năng lượng khỏi NDC. Việt Nam cũng đã gần như chưa hề để tâm đúng mức tới giảm phát thải trong giao thông vận tải, một ngành vẫn gần như phụ thuộc hoàn toàn vào xăng dầu. Ngoài ra, Việt Nam chưa tìm ra cách hiệu quả để tạo ra sự cạnh tranh trên thị trường năng lượng, khiến cho giá năng lượng phù hợp hơn với thực tế thị trường và hiệu quả hơn.

Đầu tư trực tiếp nước ngoài (Foreign direct investment – FDI) vào lĩnh vực năng lượng còn yếu. Việt Nam cần hỗ trợ về vốn từ các nhà đầu tư quốc tế và các tổ chức cho vay để tạo ra một bước tiến lớn trong ngành năng lượng. Nằm trên lộ trình của Sáng kiến ​​Vành đai và Con đường của Trung Quốc (Belt and Road Initiative – BRI), Việt Nam có thể hưởng lợi từ các dự án BRI, nếu các dự án đó phù hợp với những đánh giá và mong muốn của Việt Nam. Vốn Hỗ trợ Phát triển Chính thức (ODA) từ các nước khác tài trợ cũng có thể giúp ích. Nhưng quan trọng nhất, môi trường pháp lý phải được cải thiện để tạo ra sự cạnh tranh và do đó, có được lợi nhuận hợp pháp trên thị trường.

NREL Research Points to Strategies for Recycling of Solar Panels

Researchers at the National Renewable Energy Laboratory (NREL) have conducted the first global assessment into the most promising approaches to end-of-life management for solar photovoltaic (PV) modules.

PV modules have a 30-year lifespan. There is currently no plan for how to manage this at end of their lifespan. The volume of modules no longer needed could total 80 million metric tons by 2050. In addition to quantity, the nature of the waste also poses challenges. PV modules are made of valuable, precious, critical, and toxic materials. There is currently no standard for how to recycle the valuable ones and mitigate the toxic ones.

Numerous articles review individual options for PV recycling but, until now, no one has done a global assessment of all PV recycling efforts to identify the most promising approaches.

“PV is a major part of the energy transition,” said Garvin Heath, a senior scientist at NREL who specializes in sustainability science. “We must be good stewards of these materials and develop a circular economy for PV modules.”

Experts warn of scorching-hot growth of solar power in Vietnam

vietnamnet

The total capacity of solar power projects registered by investors has become nearly 10 times higher than the targeted level.

The solar power market began exploding in November 2017, when the Prime Minister signed Decision 11, setting the highest ever FIT (feed in tariff) of 9.35 cent per kwh, or VND2,086 for solar power. The electricity purchase price is applied for 20 years to power projects that became operational prior to June 31, 2019.

The decision triggered a wave of hundreds of businesses pouring hundreds of trillions of dong into solar power projects. Tiếp tục đọc “Experts warn of scorching-hot growth of solar power in Vietnam”

Lỗ hổng an ninh năng lượng – 5 bài

Trong 3 năm trở lại đây, đầu tư cho ngành năng lượng, gồm điện – than – dầu khí, suy giảm đã tạo ra khoảng trống, gây áp lực lớn lên an ninh năng lượng của nước ta. Với một nền kinh tế có tốc độ tăng trưởng cao, liên tục, để thoát “bẫy thu nhập trung bình”, thì an ninh năng lượng phải là trụ cột trong chính sách phát triển, chứ không thể là “gót chân Asin” của nền kinh tế.

Key Questions When Considering On-Site Solar PV: An Introductory Guide for Commercial & Industrial Facilities in Vietnam

Clean Energy Investment Accelerator Vietnam 

If you decide that on-site PV is of interest to you, based on this checklist, the next step would be to perform a more detailed technical and engineering feasibility assessment. Checklist to Determine if Your Factory Should Explore Solar PV Key questions to ask about your facility are listed below. More detail for each can be found in the sections that follow.

✓ Does your factory own the building or have a long-term lease (20+ years)?

✓ Do you have space available on your roof for solar panels and/or sufficient land for a ground-mounted system?

✓ Is the roof structurally sound and will it be in place for the duration of the economic life of the solar PV system (typically, 20-25 years?)

✓ Are there any trees, walls, buildings or other structures that shade the area where the solar panels would be located?

✓ Does the factory’s operational schedule and electricity consumption align with solar production?

✓ Does your company allow the use of operational budgets to lease equipment? Or does your company’s budget allow for equipment to be purchased with capital budgets?

✓ If your company is interested in a solar lease, would it be able to sign at least a 10-year contract?

✓ Would your solar PV system qualify for incentives, such as net metering and tax breaks? If you answer YES to all these questions, your factory is well positioned to consider solar. If you answered NO to some of these questions, there may still be other options for renewable energy procurement. The following sections provide a deeper look at these considerations and offer a more detailed explanation of the primary and current financing options for on-site solar PV electricity in Vietnam.
