Using rooftop solar power (DMTAM) not only saves costs, protects the environment, but is also considered an effective and investment-worthy power saving solution for localities at the present time.
What are the benefits of installing a rooftop solar power system?
Along with the development of the industrial revolution 4.0, solar energy systems have been gradually gaining popularity in the past few years.
In particular, nature has endowed our country with a suitable geographical position to develop solar energy, stretching from North to South with four sunny seasons all year round, which are favorable opportunities for us to develop solar energy. develop this energy source.
The use of solar energy systems will contribute to saving electricity, increasing production and business efficiency, while protecting the environment and responding to climate change.
Besides, the installation does not take up land; Helps enhance effective heat resistance for works; Having a small scale, distributed installation should be connected to the existing low- and medium-voltage power grids, without the need to invest in additional transmission grid systems.
Currently, solar energy systems are installed on roofs in cities and industrial zones, which has the effect of reducing the overload of the transmission grid from traditional power sources, which are often located far from the centers. populous.
In addition, rooftop solar power with a small scale, suitable to encourage many individuals and organizations to participate in business investment with small capital, achieve the goal of socialization; easily raise capital.
According to the Vietnam Energy Association, to produce 1 MW of solar power, it takes up to 1 ha of land to implement the project. Therefore, rooftop solar power is being widely deployed by many businesses and is receiving a positive response from the people.
According to the National Power Development Plan for the period 2011-2020 (with prospects to 2030), the total national power capacity needs to reach 60,000 MW by 2020, 96,000 MW by 2025 and 130,000 MW by 2030. . However, at present, the total power capacity of the whole system in our country has only reached 45,000 MW.
Therefore, in the planning, priority has been determined to develop electricity from solar energy, 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 both power sources.
Therefore, in order to take advantage of the large roof area in residential areas and businesses, which already have adequate grid infrastructure, convenient to connect to the grid, rooftop solar power is considered as The most effective solution available today.
In addition, the development of rooftop solar PV brings benefits to the State and electricity users. That is to have more clean energy sources with relatively high output (if investment is encouraged), minimize the budget capital invested in power generation projects and power transmission grids.
It is estimated that only about two million roofs in Vietnam need to install rooftop solar PV with a capacity of 10 kW/roof, which will reduce the equivalent of about 16 million tons of coal/year used for coal-fired power.
Allowed to sell electricity to EVN
Notably, the installation of rooftop solar PV reduces maximum electricity costs for the family, the highlight of this power system is that when there is excess electricity that is not in use, customers can sell it back to the Electricity industry, with an average price of 2,068 VND/kWp (According to Decision 11/2017/QD-TTg of the Prime Minister).
Using solar power not only saves costs, protects the environment, but is also considered an energy-saving solution that is worth an effective investment in the present time.
Many preferential policies, supporting DMTAM
Currently, solar power projects are being implemented strongly in Vietnam after the Prime Minister issued Decision No. 11/2017/QD-TTg on the mechanism to encourage the development of solar power projects.
As of April 2019, 1,379 customers in Ho Chi Minh City have installed solar power on the roof. On May 9, 2019, people investing in solar power in Ho Chi Minh City were paid for the first time after a period of generating 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 projects in Vietnam, including the selling price of electricity from solar power plants. , including from Solar and Solar Farms is 9.35 US cents/kWh (2086 VND/kWh at 2017 exchange rate).
After that, there was Circular 16/2017 /TT-BCT dated September 12, 2017 of the Ministry of Industry and Trade regulating project development and the Model Power Purchase Agreement applied to Solar PV projects that had promotional contents. encourage and guide the electricity buyers (electricity units belonging to EVN) and the electricity sellers to make electricity purchase and sale contracts on the basis of the Model Contract promulgated by the Ministry of Industry and Trade.
To further encourage the development of Solar Power, on January 8, 2019, the Prime Minister again issued Decision No. 02/2019/QD-TTg on amending a number of articles of Decision No. 11/2017/QD-TTg. on 11/4/2017, in which instead of households investing in DMTAM only selling the remainder of electricity from DMTAM sources as prescribed before (through the clearing mechanism), they will be able to sell the entire amount of electricity produced from DMTAM at a price incentives, still buy electricity from EVN separately at the current price (average 1720 VND/kWh) via 2-way galvanometer.
Electricity of Vietnam (EVN) said that although it has to buy electricity from solar power sources at a price higher than the current average electricity price, it comes from the common interests of society and the interests of the people. enterprises, EVN has been carrying out many activities to support and encourage solar power.
Specifically, EVN has issued documents No. 1337/EVN-KD dated March 21, 2018 and document No. 5113/EVN-KD dated October 9, 2018 to power corporations and Electricity Telecommunications Company. and Information Technology on temporary guidance for rooftop solar projects, including initial guidelines to facilitate business and private investment in solar PV development.
In order to encourage the development of Solar Power, in early May 2019, HDBank said that it will provide special funding for rooftop solar power projects. Specifically: Enterprises investing in rooftop solar power projects will enjoy preferential loans at HDBank with the rate of 70%, the loan term is 5 years.
The main collateral is a rooftop solar power system with a funding level of up to VND 10 billion. This offer is open to all corporate customers across the country. Simultaneously, HDBank also supports affiliate partners specializing in system installation, construction, maintenance and warranty.
