Utilization of Solar Photovoltaic to Support Community-Based Business in Gunungkidul: A review on Techno-economic-environment Nexus

Developing solar photovoltaic (PV) to support micro, small and medium enterprises (MSME) in Indonesia continues to grow. This paper presents the ecosystem development to implement PV-based businesses run by the community. This community is led by a local Islamic financial institution, BMT UMMAT, located in Gunungkidul Regency. It is a cooperative with more than 3,000 active members. The construction of a 6,000 Wp solar PV was carried out to support the processing drinking water business. The drinking water treatment system applies reverse osmosis (RO) technology. Its production capacity is 80 bottles per day; one bottle contains 19 liters of drinking water. Based on the economic calculations, BMT UMMAT will profit 18.9 million rupiahs from this business in the first year. In addition, the potential reduction of CO2 emission is 7.56 tons/year. Solar PV installation also reduces electricity costs by IDR12,996 million/year. Solar PV development for MSME provides tangible and intangible benefits for the community based on the technical, economic, and environmental aspects. The mentoring and monitoring process involves the vocational high school in Gunungkidul Regency. It is important to maintain the sustainability of the solar PV and RO system that has been installed.
