Instead of spending millions of VND each month on electricity, Ms. Tran Bao Ngoc's family (Long Bien ward, Hanoi) said that they have reduced about 90% of electricity costs thanks to installing a rooftop solar power system 7-8 years ago.
According to Ms. Ngoc, at that time, the family invested about 400-500 million VND due to the large number of members and high electricity demand. For households with average usage, installation costs usually range from 200-250 million VND.
That was the investment level 7-8 years ago, but now the cost is much cheaper" - Ms. Ngoc said.
Thanks to the rooftop solar power system, the family's electricity bill has decreased significantly. If previously I had to spend 4-5 million VND per month, now it is only about 500,000 VND.
In the context that electricity prices may increase during peak hours, I see that the trend of self-production and self-consumment of electricity will be more concerned by many families with large use needs. Currently, investment costs are also more diverse, about 80-150 million VND depending on the scale. In return, this is a long-term investment that helps save electricity bills for many years" - Ms. Ngoc shared.
Not only shopping centers or large hotels prioritize using solar power products, the demand for installing this system in households is also increasing.
Mr. Do Minh The - Head of Business Department of Vic Solar Energy Co., Ltd. - said that the company's main customer group today is households and houses.
According to Mr. The, summer is usually a potential period for the market thanks to high sunshine hours and better solar power exploitation efficiency. After a period of stagnation due to the recent holidays, customer demand is gradually stabilizing and tending to increase.
Households with electricity bills of about 2-3 million VND/month are often interested in systems with an investment of about 100-150 million VND" - Mr. The said.
Representatives of this business also said that the actual efficiency of current solar power systems is relatively close to the parameters announced by manufacturers.
Many customers reflect that the amount of electricity generated is quite abundant, even at times it is not used up. The efficiency of conversion from solar energy to electricity is currently relatively good, which can meet the normal living needs of households" - Mr. The said.
According to him, equipment quality is the decisive factor for operating efficiency. Most of the equipment used today has clear origins, is genuinely imported, so the quality and conversion efficiency are at a high level, receiving positive feedback from users.
