Rooftop solar power systems will flourish in the coming years

DTCK) Rooftop solar power is receiving a lot of support to accelerate in the near future, possibly exploding in the last months of 2019.

Good signal on price

Decision No. 11/2017/QD-TTg of the Prime Minister on the mechanism to encourage solar power development has expired from June 30, 2019.

However, according to the latest draft proposed by the Ministry of Industry and Trade, the price of rooftop solar power remains the same at the preferential level of 9.35 cents/kWh, while the price of floating solar power and ground-mounted solar power is adjusted. sharp reduction. This is considered a great driving force for the growth of rooftop solar power in Vietnam.

According to data announced by Vietnam Electricity Group (EVN), by the end of August 2019, there were nearly 13,000 rooftop solar power projects registered to sell electricity to the Group, with a total electricity output of 30,000 units. 5 million kWh.

It is expected that by the end of 2019, an additional 300 MW of rooftop solar power will be installed and by the end of 2020, the total rooftop solar power capacity can reach 2,000 MW.

Sharing with reporters from the Securities Investment Newspaper, the Clean Energy Investment Promotion Organization (CEIA) in Vietnam said that the growth of the solar power market in the first half of 2019 has proven that the program FIT (with clear instructions on payment, pricing policy and electricity usage) has created a vibrant market for rooftop solar power projects.

The total installed capacity of rooftop solar power in Vietnam has increased more than 10 times, from about 18 MWp at the end of 2018 to more than 200 MWp to date. CEIA is an initiative created to overcome barriers in expanding the use of clean energy in developing countries, including Vietnam.

The impressive growth momentum of Vietnam’s rooftop solar power market comes from two main factors: first, the attractiveness of FIT prices encourages private investment capital flows into this field; Second, rooftop solar power is often more price competitive when compared to using electricity from the grid.

The above two factors have created great motivation for project development businesses, energy service companies and large energy users (in the commercial and industrial sectors) to participate more deeply in the market. rooftop solar power field.

If the current FIT price of 9.35 cents/kWh is extended until 2021 as the latest draft, this will be a positive signal to the market. Even if the price policy changes, the benefits of self-producing and consuming rooftop solar power are still very attractive.

“Transparent and stable policies with rooftop solar power, combined with increased demand for electricity and the possibility of a shortage of electricity supply from EVN in the medium term are the main driving forces to help the electricity market. Vietnam’s rooftop solar system develops sustainably”, CEIA commented.

Expected to explode from the end of the year

Currently, many solar power plants cannot generate full capacity to the national grid, because the local power transmission grid is overloaded, due to the explosion of plants to enjoy preferential electricity prices before 30 /6/2019.

In this context, rooftop voltage is increasingly encouraged to be used, because it can reduce pressure on the transmission system.

Vietnam is considered to have great potential for solar power. In particular, the application of roof-mounted solar battery systems to produce electricity will contribute to helping families and businesses significantly reduce electricity costs and reduce the pressure on electricity supply for the electricity industry, especially in winter. hot season.

Rooftop solar power businesses are clearly aware of the opportunities for this field and are having strategies to focus on exploiting the opportunities.

Ms. Nguyen Ngoc Quynh, Director of SolarBK Business Division, said that maintaining the current preferential rooftop electricity price until 2021 according to the draft of the Ministry of Industry and Trade is something that businesses in the industry have predicted in advance. , based on the history of industry development from your countries.

“We believe that this draft will soon be approved, or the official policy will not be much different. The purpose of the policy is to encourage the market to focus on developing rooftop solar power, instead of ground-mounted and floating solar power projects, which are difficult to meet in terms of capacity compared to infrastructure. our country’s current power grid. By keeping the purchase price of rooftop solar power unchanged, the market is expected to have strong development in the fourth quarter of 2019, marking the success of the solar power industry,” Ms. Quynh said.

According to SolarBK, as of early September 2019, there were about 1,400 customers installing the company’s BigK solar power system and the number of customers is on an increasing trend.

This shows that the electricity purchase price policy greatly affects ground-mounted and floating solar power projects, but has a negligible impact on rooftop solar power.

Because, people install rooftop solar power for the purpose of using electricity directly rather than investing in selling electricity. If the electricity purchase price of 9.35 cents/kwh for rooftop solar power is officially approved, the rooftop solar power market will develop strongly in the last months.
