How much does a solar project cost in Vietnam?

Overall, projects with storage receive higher FIT rates. Previously, Vietnam's FiTs were relatively low. In January 2023, the top rate was NT$1.49/kWh for ground-mounted solar and NT$1.89/kWh for floating solar, with no regional or storage-based distinctions.

How do solar tariffs work in Vietnam?

Under the revised tariff framework, solar installations are categorized into ground-mounted and floating types, and are further segmented by region—North, Central, and South Vietnam. Rates are adjusted based on factors such as solar resource availability, cost structure, and local grid demand. The inclusion of storage also affects pricing.

What are the conditions for solar storage in Vietnam?

Conditions for systems with storage include a minimum storage capacity of 10% of the solar plant's installed capacity, a charge/discharge time of 2 hours, and at least 5% of total generation used for charging the storage system. Overall, projects with storage receive higher FIT rates. Previously, Vietnam's FiTs were relatively low.
