With small and convenient capacity, solar power (DMT) installed on the roof not only helps to save costs, but also contributes to reducing the pressure on investment in power sources, reducing environmental pollution…
Step by step “walk” into life
Previously, solar energy was considered a luxury energy source due to high investment rate, now, with the strong development of science and technology, solar power has begun to come to life, many families, Business use, bring efficiency. Le Minh Duong’s family (Dong Da district, Hanoi) installs 12 solar panels on the roof, with a total capacity of 3.6 kWp, saves from 1.2 to 1.4 million dong monthly. electricity. Mr. Duong shared: “With the initial investment of about 16 million VND / kWp, 5 years later, my family will pay back. From the 6th year on, the family will earn an interest of nearly 20 million VND / year. In particular, the solar cell has a very long life span of 20-25 years ”.
At the Ba Ria – Vung Tau Power Company, since putting into use the PV system installed with roofs with a capacity of 140 kWp in the Office Building, on average, the Company has saved more than 21 million dong of electricity per month. In addition, roof-mounted solar PV has also been deployed and applied in many places across the country, bringing practical results such as: United Nations Building in Vietnam, National Convention Center, Office of the Ministry. Industry and Trade,…
According to Professor, Academician Tran Dinh Long – Vice President of Vietnam Electricity Association, the advantage of PV roofing is not to occupy land but to use the available roof area. Generated electricity can be used directly for home needs or connected to the grid electricity.
Therefore, if households and businesses have favorable premises and conditions to receive sunlight, they should install PV and take advantage of renewable energy. In particular, with office buildings, apartment buildings, the installation of PV on the roof has more than enough power to supply the elevator, air-conditioning, hot water system … bringing very high economic efficiency.
However, according to experts, when installing, households need to pay attention to safety issues and need experts to advise and support for solar resources to bring into full play.
Facing challenges of energy demand to ensure sustainable economic growth, especially the exhaustion of fossil fuels, environmental pollution and climate change. Incentive policies from 2015 to 2017 have created a “sprint” to take advantage of opportunities to provide renewable energy in Vietnam.
Not only attracting domestic contractors, Vietnam also recorded a series of “million dollar” solar power projects from foreign investors such as: Tata Power plant with capacity of 300 MW in Ha Tinh, Hanwha factory. capacity of 100-200 MW in Thua Thien Hue, GT & Associates and Mashall & Street Ltd plant with 150 MW in Quang Nam.
Geographically, Vietnam possesses great potential for harnessing solar energy because it is close to the equator and exists in dry and sunny regions like the southern central provinces. Only in the first half of 2018, the Ministry of Industry and Trade recorded 272 solar power plant projects with a total capacity of about 17,500 MW, 9 times more than Hoa Binh hydropower plant and 7 times more than Son La hydroelectric plant.
In addition, the plentiful supply from solar power projects is being considered by experts to propose alternatives to nuclear power plants, when Vietnam has stopped nuclear power projects until 2030.
Vietnam is located near the equator, neatly located in the tropical climate belt of the northern hemisphere, with high annual average radiation background, year-round radiation balance, so the solar energy market is fast. quickly become a lucrative cake attracting domestic and foreign investors to participate. According to a report from the Ministry of Industry and Trade, by December 2019, there were more than 87 projects operating with maximum design capacity, more than 260 solar projects are waiting for approval.
In the future, the renewable energy revolution in Vietnam can lead the investment trend. And the amount of electricity that the energy industry produces will help strengthen energy security while solving the pressure transmission problem in Vietnam.
There will always be more support and decision-making from the leaders and leaders of each nation to push this revolution into a future perspective, where energy is not. is also a concern in any country.
There is a need for incentives for development
Professor, Academician Tran Dinh Long said that one of the barriers to PV development is high investment rate compared to other energy sources. Therefore, if there is a mechanism to support and encourage development such as price support, the grid-connected PV system will have a chance to thrive.
“PV in Vietnam usually has the highest generating capacity from 9am to 15pm. Therefore, if the regulation of selling electricity during peak hours is charged at a higher price, and using electricity during peak hours has to pay high prices, the PV sources will be more profitable and the payback time will also be faster ” , Professor, Academician Tran Dinh Long said.
Last April, the Prime Minister issued Decision No. 11/2017 / QD-TTg on mechanisms to encourage the development of solar power projects in Vietnam, with many tax incentives and selling prices for PV. However, experts say that, apart
