ABSTRACT
The principal alternative to Photovoltaic (PV) is the use of fossil-fuel-powered generators. As has been indicated, the units are frequently out of service as they are very difficult to maintain and operate properly, given the relative inaccessibility of the sites. Notwithstanding the basic simplicity of a solar PV system, the remoteness of the sites where the schools are located, the inexperience of the staff operating the systems and the lack of training contribute to problems with maintenance. In Argentina, there are thousands of rural schools that are not connected to the grid. While this number is diminishing, there is great potential for PV systems to meet the basic electrical requirements of the remaining schools. It is essential that the school caretakers be involved in the use and maintenance of the systems, given the relatively high turnover of the teaching staff. Steps have been taken by the local utility to ensure that its local offices verify the system maintenance.
