Using rooftop solar PV (DMT) not only saves costs, protects the environment but is also considered an energy saving solution worth investing in and effective for localities in the present time.
Benefits when installing rooftop solar power system?
Along with the development of the industrial revolution 4.0, solar systems have been gaining popularity in the past few years.
In particular, nature has endowed our country with a suitable geographic location to develop solar energy, stretching from the North to the South with four sunny year-round seasons, which are favorable opportunities for us. develop this energy source.
The use of solar energy systems will contribute to saving electricity, increasing the efficiency of production and business while protecting the environment and coping with climate change.
Besides, the installation does not take up land area; Help enhance effective anti-heat for buildings; Small scale, scattered installation should be connected to the existing low and medium voltage grid, no need to invest in additional transmission grid system.
Currently, the solar system installed in many rooftops in cities and industrial parks has helped reduce the overload of transmission grids from traditional power sources, often located far from centers. populous.
In addition, rooftop solar PV is small in size, suitable to encourage many individuals and organizations to invest in business with small capital, meeting the goal of socialization; easily mobilize capital.
According to the Vietnam Energy Association, to produce 1 MW of solar power, it takes 1 ha of land to implement the project. Therefore, rooftop solar power is being widely deployed by businesses and has received positive responses from the people.
According to the National Power Development Plan for the period of 2011-2020 (considering prospects to 2030), by 2020 the total national power capacity needs to reach 60,000 MW, 96,000 MW by 2025 and 130,000 MW by 2030. . However, at present, the total capacity of the whole system is only 45,000 MW.
Therefore, the plan has identified the priority to develop solar power, which will increase the installed capacity from 6-7 MW in 2017 to 850 MW in 2020 and about 12,000 MW in 2030, equivalent to with 1.6 and 3.3% of the total capacity of the power source.
Therefore, to take advantage of the large roof area in residential areas, businesses already have adequate grid infrastructure, convenient in grid connection, rooftop solar power is assessed as The most effective solution today.
In addition, the development of rooftop PV will benefit the State and electricity users. That is having more clean energy sources with relatively high output (if encouraged to invest), minimizing the budget capital invested in power generation and power transmission grid projects.
It is estimated that only about two million roofs in Vietnam will install roof PV with a capacity of 10 kW / roof, which will reduce approximately 16 million tons of coal per year for coal thermal power.
Allowed to sell electricity to EVN
Notably, the installation of rooftop PV reduces the maximum electricity cost for the family, the highlight of this electricity system is that when there is an unused surplus of electricity, customers can resell it to the Electricity industry, with an average price of VND 2,068 / kWp (According to the Decision 11/2017 / QD-TTg of the Prime Minister).
Using DMAM not only saves costs, protects the environment but is also considered an energy saving solution worth investing in currently.
Many preferential policies, supporting DMAM
Currently, solar power projects are being strongly implemented in Vietnam after the Prime Minister issued Decision No. 11/2017 / QD-TTg on mechanisms to encourage the development of solar power projects.
As of April 2019, 1,379 customers in Ho Chi Minh City installed solar power on the roof. On May 9, 2019, people investing in solar power in Ho Chi Minh City for the first time were paid for electricity after a period of generation of electricity on the grid.
On April 11, 2017, the Prime Minister issued Decision No. 11/2017 / QD-TTg on the mechanism to encourage the development of solar power projects in Vietnam, including the sale price of electricity from PV plants. , including both DMT and DMAM farms was 9.35 US cent / kWh (2086 VND / kWh at the 2017 exchange rate).
After that, there was the Ministry of Industry and Trade’s Circular No. 16/2017 / TT-BCT dated September 12, 2017, on project development and sample power purchase contract applicable to solar power projects that had promotion contents. encourage and guide the electricity buyers (electricity units under EVN) and the electricity sellers to formulate electricity trading contracts on the basis of model contracts promulgated by the Ministry of Industry and Trade.
In order to further encourage the development of DMAM, on January 8, 2019 the Prime Minister issued Decision No. 02/2019 / QD-TTg on amending a number of articles of Decision No. 11/2017 / QD-TTg. April 11, 2017, in which instead of households investing in DMAM, they only sell the residual amount of electricity from the DMAM source as previously prescribed (through the compensation mechanism), they will be able to sell all the electricity produced from DMAM at the price Incentives, but still separate purchase of EVN with the current price (average 1720 VND / kWh) via 2-way galvanometer.
The Electricity of Vietnam (EVN) said that although it must buy electricity from solar power sources at prices higher than current average electricity prices, it comes from the common interests of the society and the interests of the people and businesses, EVN have been conducting many activities to support and encourage DMAM.
Specifically, EVN has issued documents No. 1337 / EVN-KD on March 21, 2018 and documents No. 5113 / EVN-KD on October 9, 2018 to power corporations and Electricity Telecommunications Company. and Information Technology on the temporary guidance for rooftop PV projects, including initial guidelines to create favorable conditions for businesses and individuals to invest in developing DMT.
In order to encourage the development of DMAM, in early May 2019, HDBank said it would sponsor specifically for rooftop solar power projects. Specifically: Enterprises investing in rooftop solar power projects will enjoy preferential loans at HDBank with the rate of 70%, 5-year loan term.
The main guarantee is the rooftop solar power system with the funding up to 10 billion VND. This offer is available to all business customers across the country. At the same time, HDBank also supports associate partners specializing in installation, construction, maintenance, and system maintenance.
