Photovoltaic Rural Electrification

The history of photovoltaic rural electrification (PVRE) from the early systems installed at the end of the 1960s is reviewed and presented in three different contexts: developed countries, international aid and developing countries. The progression from community applications (school televisions, village drinking water pumps, health centres, etc.) to individual applications (domestic electrification) is outlined. Differences between the concepts of ‘basic’, ‘perceived’ and ‘standard’ electricity needs are discussed. Relative advantages of the different products comprising current PVRE are analysed in the light of potential user perceptions. Proposed large-scale PVRE programmes based on solar home systems are analysed, paying special attention to two aspects that have become controversial issues in the PV community: the capabilities and role of the users; and the need for systematic quality control procedures. Finally, some economic figures related to investment and maintenance costs are proposed.
