DAT SOLAR interacts online with readers of Thanh Nien newspaper
Currently, DAT Solar has gained trust from EVNHCMC and Thanh Nien newspaper. On the morning of March 28th, DAT Solar participated in an online discussion and exchange session with the readers of this newspaper on the theme of “Saving, Electrical Safety, and Consultation on Installing Solar Panels on Rooftops.” This was an opportunity for all three parties (Solar Company – Residents – Power Company) to share, listen, and provide direct advice with multidimensional, publicly verified information.
Present at the discussion was Mr. Le Minh Hien, Head of Solar Business Department at DAT, who collaborated with representatives from EVNHCMC to answer readers’ questions under the moderation of Thanh Nien newspaper. Below are the questions that readers were particularly interested in when considering installing solar power for their homes or businesses, so stay tuned as there might be useful information for you.

Hello,
– For investors who are businesses issuing invoices: Monthly, the electricity sector receives and pays the electricity bill according to the invoice issued by the investor.
– For investors who are households, individuals not issuing invoices: Monthly, they pay the electricity bill to the investor (the payment does not include value-added tax). After the end of the year or the contract, the two parties will settle the value-added tax according to regulations.
Regards.

In Northern Vietnam, during the winter days when it’s often overcast and there’s no sunlight, how will solar energy work to ensure a stable power source for households?

#MR. MINH HIEN LE Solar Sale Manager – DAT
Thank you for the question. The electricity production of the solar system in the northern region is slightly lower than in the southern region. According to DAT’s statistics, the average electricity production during the day is about 3.5 kWh/kWp in the North compared to > 4 kWh/kWp per day in the South. Therefore, the payback period may be slightly longer than investing in the South. However, considering sunlight radiation, the North is still much more efficient than many European countries (which are highly developed in solar power). Regarding cloudy days, when the system’s output decreases, electricity from the grid will automatically supplement to ensure stable use of electricity in the house. In simpler terms, the stronger the sunlight, the more cost-effective energy savings. The system will remain stable throughout the year regardless of the weather at that time.

How much does an average rooftop solar power system weigh? For roofs that are not very sturdy, what is the solution?

#MR. MINH HIEN LE Solar Sale Manager – DAT
Hello Hoang,
The rooftop solar power system, if installed according to DAT Solar’s specialized toughened aluminum standard, will have a solid structure and a lighter weight. The entire system will weigh about 13 kg/m2. Most existing roofs in Vietnam can withstand this weight without the need for additional structural reinforcement. Of course, during the consultation and survey process, DAT’s engineers will assess the roof structure and provide the most suitable technical and economic advice for customers.
Thank you.

My house has a dormitory area for students, about 600m2. It has single-phase electricity. The monthly electricity cost is over 3 million VND, at the household rate. I plan to install solar panels, but I’m not sure if a system with a capacity greater than 5kWp can be connected to the grid?

The price EVN buys back is about 2000 VND, fixed for 20 years. Is this unfair to users of solar energy?

Hello,
The purchase price of solar power according to Decision 11/2017/QD-TTg is currently 9.35 US cents/kWh valid until June 30, 2019. In the case of investors connecting solar rooftop systems to the grid and signing contracts with the electricity sector, this contract will have a fixed price for 20 years. However, depending on the contract signing time, the VND price is converted according to the central exchange rate between the Vietnamese dong and the US dollar announced by the State Bank of Vietnam (this price is fixed for 20 years of the contract, not depending on the exchange rate in subsequent years). Specifically:
– Before January 1, 2018, the purchase price was 2,086 VND/kWh.
– From January 1, 2018, to December 31, 2018, the purchase price was 2,096 VND/kWh.
– From January 1, 2019, until there is a new decision from the Prime Minister in 2019, the purchase price is 2,134 VND. Regards./.

Hello,
Solar power systems should be installed on rooftops, where there is no shading and a sturdy structure. Solar panels should be installed facing south for optimal electricity production throughout the day. In Southern Vietnam, provinces and cities with the highest electricity production are recorded in Ninh Thuan, Binh Thuan (due to the best solar radiation) or areas in Daklak with cool weather, optimizing the system’s operational efficiency.
You can visit DAT Solar’s website: www.datsolar.com for reference on projects that DAT has installed nationwide.
