Grid-connected PV for Malaysian residential sector has been analyzed using HOMER.
Component costs, feed-in tariffs, and carbon taxes affect optimal system types.
Grid-connected PV projects are feasible for low PV array costs ($ 1120/kW or lower).
For higher PV array and inverter costs, feed-in tariffs should be implemented.
Combining feed-in tariffs with carbon taxes are effective for further lowering NPCs.
