Globally, hybrid systems are widely used in isolated areas as an alternative in providing electricity. Along with the development of its technology, its use in the world is becoming more widespread. Indonesia has the potential of renewable energy sources, especially solar energy which can be combined with diesel generators to provide electrical energy for isolated areas. The purpose of this study is to find out the benefits, constraints, and factors that affect the sustainability of the hybrid system. This study was conducted by analyzing the literature related to the use of hybrid systems in isolated areas in terms of components, prices and operations. Some research related to hybrid system in remote areas also becomes a further approach which are carried out as an evaluation of optimization. The hybrid system makes diesel generators more efficient in operation and maintenance cost. Hybrid system generation cost continues to decline but the prices of some components are still significant. Fulfilling electricity needs in isolated areas can not only provide benefits for residents but also tend to trigger an increase in electricity consumption. Human resources are often an obstacle in isolated areas related to troubleshooting . Long-term continuity of after-sales service is very important.
