EVN estimates a VND 12.215 trillion profit for the first eight months of 2026 and has cleared accumulated losses, according to VnExpress. Homeowners assessing rooftop solar should start with how much solar electricity they can use at home and the grid electricity costs it could avoid.
According to VnExpress on September 15, 2026, EVN Board of Members Chairman Đặng Hoàng An said the group had cleared accumulated losses from previous years and estimated a profit of VND 12.215 trillion for the first eight months of 2026. This is an update on EVN’s financial performance. The supplied source text does not mention a residential electricity tariff adjustment, so this report provides no basis for concluding that household electricity bills will fall.
For homeowners in Vietnam, a practical response is to assess the electricity costs their household can actively reduce. Rooftop solar can reduce purchases from the grid when the electricity it generates is used directly at home. Its value should therefore be assessed against each household’s actual consumption, rather than expectations that electricity prices will change following EVN’s return to profit.
Start by gathering the past 12 months of electricity bills and recording which appliances usually run during the day, such as air conditioners, washing machines or water pumps. During a roof assessment, ask the installer to explain expected generation, the share that can be used at home and how that electricity translates into savings under the tariff applicable to the household. Distinguish total generation from the electricity that actually replaces grid purchases.
A household with substantial daytime consumption may have more opportunity to use solar electricity directly than one that mainly consumes electricity in the evening. If demand is concentrated in the evening, consider shifting suitable tasks to sunny hours. Battery storage should only be considered as an option supporting the rooftop solar system, after comparing additional savings with the extra cost and storage losses.
Before investing, homeowners should request a system size matched to demand and a savings calculation that states its assumptions, installation and maintenance costs, and estimated payback period. EVN’s clearance of accumulated losses provides context; the decision to install rooftop solar should rest on its ability to reduce that particular home’s electricity bill.
