Vietnam has enacted a policy allowing households with rooftop solar panel systems to sell up to 50% of their excess electricity back to the national grid. This initiative encourages the adoption of renewable energy sources at the residential level. The current regulation permits the sale of surplus power generated for self-consumption, with any remaining electricity fed back into the grid. Authorities indicated the potential for increasing this percentage beyond 50% by the end of 2030, contingent on the grid’s capacity to accommodate additional power. The move aims to promote sustainable energy practices and reduce reliance on traditional power sources. This policy provides a financial incentive for homeowners to invest in solar energy and contribute to Vietnam’s energy transition goals. The government will assess grid capacity regularly to determine future adjustments to the surplus power allowance.
