“…In general, when water resource is sufficient, PA always considers the microhydro power as the first option , since these systems are usually the lowest cost option for off-grid rural electrification (Coello et al, 2006;Kaygusuz, 2011;REN21, 2008;Williams and Simpson, 2009), are reliable for off-grid systems (van Els et al, 2012), and the energy is continuously available (Drinkwaard et al, 2010), . If water resource is not available, photovoltaic (PV) or wind systems are used, depending on resource availability, as their suitable to provide decentralized electrical service to rural households (Bugaje, 2006;Jacobson, 2007;Hiremath, 2009;Kandpal, 2010a, 2010b;Ferrer-Martí et al, 2012;Valer et al, 2014). Regarding the choice between individual or collective systems, it must be noted that stand-alone systems usually have low capacity factor, high battery costs and limited capacity to store energy (Khan and Iqbal, 2005;Kaundinya, 2009).…”
