This paper describes and analyses the historical development and current status of the solar energy
markets in Kenya and Tanzania. It examines the development of both the Kenyan and the Tanzanian
solar energy markets since their beginnings in the 1970s, their current size and structure and it presents
forecasts for their future development. In addition, it highlights and explains similarities and differences
between the solar energy markets of the two East African countries. The paper is based on an extensive
literature survey that takes account of academic as well as ‘grey’ literature. The literature review has been
complemented by 25 personal in-depth interviews with leading experts on the East African solar energy
market. In the paper it is shown that the solar market of Kenya is one of the world’s leading markets for
off-grid solar uses, with an installed capacity of around 10 MWp and over 300,000 solar home systems.
The Tanzanian solar market is found to have developed much later than the Kenyan market and to remain
smaller than its neighbour, with an installed capacity of around 4 MWp and 40,000 solar home systems. In
addition to solar home systems, other segments for uses of solar energy in social institutions, telecoms and
tourism are also covered. The paper draws some initial policy conclusions regarding the regulation and
promotion of solar energy in East Africa. Awareness, availability and affordability are found to be major
drivers that all need to be present to enable the widespread uptake of off-grid solar technologies in emerging
markets.
