This momentum is expected to strengthen in particular thanks to the tax credit, since 1er January 2005 15 is passed from to 40% for equipment expenditures "Renewable Energies". To expand the promotion of collective solar water heater in 2005, ADEME strengthens its communication to communities and building managers.

In 2004 the solar thermal market grew by more than 40% with the installation of 55 340 m © ~ installed sensors (38 840 2003 in).
