        PROSOL Residentiel: Incentives for solar water heaters

        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:

        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;
        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.

        The total amount, credit plus subsidy, cannot exceed the installed system costs (before taxes). At…

        Thermal efficiency regulation of solar water heaters (NOM-027-ENER/SCFI-2018)

        The regulation establishes the thermal efficiency, gas savings and safety requirements of solar water heaters and solar water heaters backed by LPG (liquefied petroleum gas) or natural gas that are intended to be introduced into the Mexican market. Technical specifications, testing methods, and labeling are also considered by the regulation.

        Technical conditions for solar water heaters:

        Useful heat per day - 8 hours (Mega Joules) : > 12.5
        Useful heat per day - 24 hours (Mega Joules) : > 8.7
        Useful heat per year - 8 hours (Mega Joules) : > 4550
