Why do people who install solar panels on their roofs have to register with EVN?

Why must rooftop solar systems for self-consumption be registered with EVN? As electricity costs continue to rise and the trend toward green energy grows stronger, investing in solar power systems has become a smart choice for households, businesses, and production facilities. Cergy explains why even rooftop solar systems designed for self-consumption still need to be registered with EVN. Learn the reasons, legal requirements, and insights from experts and the public. According to a new proposal from Vietnam Electricity (EVN), households and organizations that install rooftop solar systems for self-production and self-consumption but fail to register or notify the authorities may face administrative penalties. How to calculate solar system capacity Why is registration of rooftop solar self-consumption systems required? 1. Ensuring electrical safety and fire protection Notification helps EVN and regulators collect accurate data, provide technical guidance, and monitor installations. This reduces risks such as: Reverse current into the grid, causing system failures. Local overloads, potentially leading to fires or explosions. Systems that fail to meet safety standards. 2. Load management and grid balance A few households may not significantly impact the system. However, if millions of households install without registration, the national grid could face severe fluctuations: Sunny days: reduced grid demand → excess supply. Stormy or rainy days: households rely on the grid again → power shortages. This forces the electricity sector to constantly maintain backup capacity, creating pressure on the system. 3. Data collection and energy policy planning Registration provides the government with accurate statistics, enabling: Rational allocation of renewable energy resources. Environmental management and risk reduction. Long-term policy support for solar power development. Community perspectives Many readers agree that registration is necessary but point out that current procedures remain cumbersome. According to Decree 58/2025, households installing rooftop solar systems for self-consumption must notify: Department of Industry

How to Calculate the Suitable Capacity of Solar Energy System

As electricity costs continue to rise and green energy becomes a popular trend, investing in solar power systems is a smart choice for households, businesses, and production facilities. However, to achieve optimal performance, calculating the correct system capacity is the most important factor. In this article, cergy.vn will guide you through determining the right capacity and choosing solar power equipment suitable for different needs—especially in regions with high solar potential such as Binh Thuan, Nha Trang, Dong Nai, and Tay Ninh. 1. Why is accurate calculation of solar system capacity important? Designing and installing a solar system is not simply about buying equipment and placing it on the roof. To ensure investment efficiency and long-term stability, accurate system capacity calculation is a critical step in the consulting and design process. Here’s why: Meeting actual electricity demandA properly sized system will generate enough electricity to power all household, business, or factory equipment—including high-consumption devices such as air conditioners, compressors, or production lines. Undersized systems force continued reliance on the grid, reducing investment value. Avoiding excess capacity – optimizing initial investmentOversized systems lead to unused electricity during off-peak hours. Without storage batteries or grid feed-in, this surplus is wasted, increasing costs without added economic benefits. Faster return on investment (ROI)A well-designed system, matched to real consumption and local sunlight, shortens the payback period. Typically, optimized systems pay off in 4–6 years and then operate with nearly zero running costs for 20–25 years. Ensuring stable and safe operationMismatched capacity can cause voltage overload, damaging inverters or household wiring. Undersized systems, on the other hand, cannot meet peak demand, especially in hot seasons when cooling and pumping systems work intensively. Adapting to local sunlight conditionsSolar radiation levels vary significantly across Vietnam. A 5kWp system in Binh Thuan may generate 15–20% more electricity than
