Solar home & pumping system scheme for lighting & access to clean water in the 3T region

There are many regions in Indonesia where the electrification ratio is relatively low, even some still do not enjoy access to electricity. Low electrification is especially felt by Indonesians living in 3T areas (terdepan/frontier, terluar/outermost, and tertinggal/disadvantaged). On the other side, as archipelagic and tropical country, Indonesia has high potential in the development of renewable energy for electrical generation especially solar energy. This study aims to design a solar home & pumping system (SHPS) model and assess its feasibility. In this concept SHPS scheme is purposed to provide electricity access to 3T community for the needs of lighting and access to clean water. A total of 4 units of 3 watt LED lights integrated with batteries are used for lighting each household, while a 600 watt water pump can be used communally for 150 households. Both LED light and water pump are supplied with electrical energy from their respective solar panels. There are 3 scenarios in the implementation of SHPS for a total of 150 households with a discount rate for investments of 10%. Full grant by the government/private sector with a budget of Rp 480.5 million is the most recommended scenario. Another advantage of SHPS is environmentally friendly.
