With the goal of achieving net-zero emissions by 2050 and amid a strong transition toward green energy, self-produced and self-consumed rooftop solar power is becoming one of the most effective solutions for both households and businesses.
Since late 2025, the rate of self-produced and self-consumed rooftop solar installations has increased significantly, following the implementation and effective enforcement of Decree No. 58/2025/ND-CP, which details several articles of the Electricity Law. However, in practice, many people still face challenges in registering for grid connection and complying with fire prevention and firefighting standards. Among the wide range of available options, choosing a solar technology that is both efficient and affordable remains a key concern.
Speaking at the studio of the program “Today’s Issue,” broadcast on VTV1 on the evening of March 28, Assoc. Prof. Dr. Duong Trung Kien, an expert from VETS | EnE, shared his perspectives on the following topics:
Updates on legal requirements for household electrical systems under Decree No. 58/2025/ND-CP
Assoc. Prof. Dr. Duong Trung Kien emphasized that this marks an important step forward in removing barriers for rooftop solar development. According to him, the new policy not only establishes a clearer legal framework but also creates opportunities for households to take a more proactive role in investing in and efficiently utilizing clean energy.
Solar power solutions for apartment buildings
Regarding the application of solar energy in apartment complexes, he noted that several new technological models have been introduced. A notable example is integrated glass systems capable of providing shading and rain protection while simultaneously generating electricity. He believes this solution can help apartment residents save electricity, particularly during peak hot seasons.
The global trend toward mandatory renewable energy adoption
On the broader trend of renewable energy use, Assoc. Prof. Dr. Duong Trung Kien stated that this will gradually become an inevitable requirement worldwide. As fossil fuel resources continue to deplete, costs rise, and pressures related to environmental protection and energy security intensify, countries are expected to shift from incentive-based policies to mandatory adoption of renewable energy.
In Vietnam, he noted that mandatory regulations may not be implemented in the short term. However, policies will likely continue to strongly encourage the adoption of solar energy, with a long-term goal of approximately 50% of households installing rooftop solar systems.
