Number of ESE installed worldwide based on manufacturing in France and in Spain has been evaluated according to official statistics. This number is of course less than the overall number of ESE installed as some manufacturer production are not included especially coming from other countries than Spain and France.
In 1986, which is the first year of available statistics, number of ESE was 4 088 when in 1996 it was already a cumulated number of 112 412 units.
In 2009 the cumulated number of installed units is 550 000.
Total number of ESE units per years is now 4 652 000 . This means that experience is very long and important.
