Vietnam has pledged to reduce methane emissions by 30%, increase renewable energy utilization, and decrease coal-based electrical power, with a goal of achieving net-zero carbon dioxide emissions by 2050. Among renewable energy sources, solar energy has gained attention due to Vietnam’s favorable location near the equator. This study aims to evaluate the economic feasibility of solar energy generation in Vietnamese households, focusing on the north, middle, and south regions. Using the Ecotect software, the study assesses the potential for solar energy production, while also examining the country’s solar power policy for electricity production. Through this analysis, the research aims to identify any weaknesses in the current policy and recommend possible solutions to maximize the economic benefits of solar energy development. The findings of this study are expected to provide insights into the economic feasibility of solar energy generation in Vietnamese households, as well as inform policymakers about the shortcomings of the current solar power policy. Ultimately, this research aims to support Vietnam’s transition towards a sustainable and prosperous future, in line with the country’s long-term goals for reducing carbon emissions and increasing the utilization of renewable energy.
