Tunisia`s solar thermal market stabilised at 64,000 m2 in 2016, a figure only slightly lower than the 65,000 m2 in 2015 and in 2014, but significantly below the peak years of 2008 to 2010. The key market driver had again been Prosol, the national residential programme launched in 2005 and based on a financial scheme combining direct subsidies of Tunisian Dinar (TND) 200 and 300 granted by the Energy Transition Fund and low-interest loans. With 90 %, residential systems still account for the largest share in newly installed collector area. However, hotels and commercial buildings have profited from Prosol Tertiary since 2009 and contributed around 5 %.
Tunisia’s incentive and low-interest loan scheme Prosol can already celebrate its tenth anniversary next year. Since 2005, the Tunisian Company of Electricity and Gas, STEG, has been managing the programme, which enables end consumers to repay a loan for a solar water heater over five years by having the instalment amount charged to their monthly STEG electricity bill. The programme was praised as an ideal showcase for the entire region, because market volume grew by more than a factor of ten in only five years. Before the start of the grant programme in 2005, Tunisia had only had an annual installation figure of 7,000 m2. In 2008, the subsidised collector area was already at 80,000 m2. But last year, market volume dropped to 53,000 m2 because of several factors listed below.

Tunisia’s government has extended the incentive and low-interest loan scheme PROSOL to 2016. The latest contract between the Tunisian Company of Electricity and Gas, STEG, and the Tunisian Attijari Bank ensures loan repayment for solar water heater purchases between 2012 and 2016. It grants users of solar water heaters five years to pay back the loan through their monthly STEG electricity bill. The electricity bill payment is the key success factor of the financial scheme PROSOL, because it is a fairly reliable way of refinancing the thousands of loans. The chart above shows the residential collector area which profited from PROSOL subsidies and loans each year.
After three years of preparation, the first Tunisian Programme of Activities (PoAs) for solar water heating was registered successfully with the Clean Development Mechanism (CDM) in April 2011. It is only the second African PoA focusing exclusively on solar water heaters after the “SASSA Low Pressure Solar Water Heater Programme” in South Africa, which started in March 2011.

Will this be the future of Nefta? The Soleil de Nefta project foresees the installation of solar energy systems of about 20 MW by 2016, in order to produce hot water, solar electricity and solar cooling energy for the city of Nefta in the south-west of Tunisia. Photo: ANME
