Tunisia set up devices to encourage the use of solar energy. These initiatives inscribe themselves in a global dynamic of sustainable development promotion, and contribute to improve the energy self sufficiency. This governmental policy supports household solar energy consumption, particularly solar water heaters, and solar panels. The analysis of the dissemination of solar home systems in urban practices is allowed by cartography of solar equipment sales within the “Grand Tunis” and by three field surveys among companies of the sector and Tunisians households.
