Energy for heating (and cooling) represents around 70% of total energy consumption in Tunisia, more than ¾ of the energy consumption of the industrial sector and up to 40% of the energy consumption of buildings. The use of Solar Thermal Energy therefore has significant potential in Tunisia’s various economic sectors.
Tunisia is blessed with an abundance of solar radiation, thanks to its geographical position, with a mean of around 2,000 kWh m‑2 yr‑1. In the country as a whole, areas with the potential for installing Solar Thermal Energy total more than 1,000,000 m2, of which the following have already been identified: 360,000 m2 in the industrial sector, 250,000 m2 in collective habitations (houses, flats, etc.), 170,000 m2 in hotels and 6,000 m2 above covered municipal swimming-pools.
Advantages and Incentives
Collective Solar Thermal Plants are subject to different grants, loans and investment assistance. These are allocated by the Fund for Energy Transition (Fonds de Transition Energétique – FTE), which represents the principal mechanism for implementing these initiatives. In addition to the FTE however, there also exists complementary assistance in the form of concessionary loans (subsidized credit lines available to developers) and grants from international co-operative funds.
Through the FTE, businesses that install Collective Solar plants may benefit from a grant of 70% of the costs of Consultants’ and Technical Advisors’ services up to a ceiling of 70,000DT; such businesses may also receive grants of 30% of the cost of investment in materials, up to a ceiling of 250DT m-2 of solar panels as indicated in the table below:
As shown in the graph below, the PROSOL Collective program allowed the installation of 35,000 m² of solar collectors between 2009 and 2019, with an average of 3,000 m² of solar collectors installed each year. thus allowing a significant change of scale in terms of achievements by going from an installed collection area not exceeding 100 m² annually until 2008 to an average of since 2009.
