An adequate and reliable electricity supply system is essential for any developing country. This paper examines the problems in the electricity supply system in Nigeria. Solar photovoltaic (PV) systems are reckoned to be viable alternatives for reliable power supply, particularly for small loads in remote areas and rural communities. The status and potential of photovoltaics in Nigeria are examined, particularly for village electrification and telecommunications. Results of surveys of PV systems installed in the country are presented and policies that would encourage the dissemination of the systems are discussed.
