This feasibility study on the productive use of energy was conducted based on an off-grid solar PV system of 95 kWp in Mata Redi and Mata Woga villages, Central Sumba. The study calculated the excess power through further simulation. It also explores the technology options and prioritises technologies with the most potential by improving the processes involved in the production lines. The study suggests interventions to maximise the productive use of excess power, especially during the day. Ultimately, this effort is expected to lead to an increase in income for local community members.This feasibility study on the productive use of energy was conducted based on an off-grid solar PV system of 95 kWp in Mata Redi and Mata Woga villages, Central Sumba.
