The IEA (2010) estimates that about 589 million people in Africa live without access to electricity [21]. Africa’s non-electrified population is expected to grow from 110 million households to 120 million households by 2015 [2]. African grid expansion is failing to keep pace with population growth. Solar technologies provide the alternative to sustainable development and […]

Most inhabitants who lack access to grid electricity are categorized as low income. Low-income consumers often do not have the initial investment needed to pur­chase new lighting products due to high up-front costs of LED solar home systems (SHS). A recent report shows that approximately 90% of households lack access to formal financial services [20], […]

Recently, OSRAM has setup an Energy Hub in April 2008 in Mbita which supplies up to 10 KW of electricity. This is enough to recharge around 350 lamps per day. In addition to the lamps, the energy hub also charges batteries that can be con­nected to electrical devices such as radios. When the lamps and […]
