Vietnam permits households to sell up to 50% of rooftop solar output to national grid

The Vietnamese government issued Decree 243/2026/NĐ-CP, effective 26 June, to revise the rules for renewable‑energy development and direct power‑purchase. Under the new regime, households with rooftop solar systems may sell a maximum of 50% of their generated electricity to the state utility EVN, a sharp increase from the previous 20% cap. The allowed share can rise further after 2030 if local grid conditions permit.

The change aims to make rooftop solar more financially attractive, giving owners an additional revenue stream and reducing wasted daytime generation. It also expands the pool of eligible producers to include single‑family homes, offices and low‑voltage grid connections. With roughly 103,000 installations totalling more than 9,500 MW, the policy supports the target of having 50% of residential and commercial buildings powered by self‑generated solar by 2030 and stimulates the domestic solar equipment and services market.
