Malaysia launches new net metering scheme for rooftop PV
Effective since January 1, 2026, the Solar Accelerated Transition Action Programme (Solar ATAP) aims to build on Malaysia’s previous net metering program’s efforts to maximize the use of rooftops for solar generation by incentivizing consumers to export excess generation to the grid. The capacity limit has been set at 100% of the consumer’s maximum demand, or 1 MW.
