Launched in 2005, the PROSOL II programme offers incentives to those purchasing solar water heaters from certified suppliers and having them installed by certified installers. The incentive system comprises: 1) A subsidy, of TND 200 for a solar water heater with 200L capacity, or of TND 400 for a solar water heater with capacity of 300L or more; 2) A credit payable within five years, and that can be paid back through bill payments to the Tunisian electricity and gas company (STEG), between TND 550 and 1150.
