| − | A mini-grid is a set of small-scale electricity generators and possibly energy storage systems interconnected to a distribution network that supplies electricity to limited number of customers. The combination of photovoltaic (PV) systems with a diesel genset and/or storage system is a flexible and usually least-cost solution for rural communities. Thus, this technology is able to tap the solar energy potential, to provide rapid, cost-effective and high quality electrification, and to allow a profit investment on renewable energy sources.
