Viet Nam has favourable conditions to develop solar energy across the country, but according to experts, it needs an economical, technically feasible net-metering scheme to promote solar PV rooftops in the country.

Net-metering is a system in which solar panels or other renewable energy generators are connected to a public-utility power grid and surplus power is transferred onto the grid, allowing customers to offset the cost of power drawn from the utility.

It also allows consumers who generate some or all of their own electricity to use that electricity anytime, instead of when it is generated.
