Remote site electrical energy production by solar hybrid system using hot air engine

This communication studies the interest of using hybrid systems to produce low power electrical energy on remote sites, e.g. for telecommunication applications. The main element of these installations is a thermal engine using external heat. The energy conversion into electricity is carried out by a thermodynamic process from solar energy or from fuel combustion. We assess the sizing of different installations designed for 1 permanent kWe, on 5 geographical localisations.
