L'invention concerne la fourniture peu onéreuse de courant pour un réseau énergétique à l'aide de l'énergie photovoltaïque (PV). Le concept servant de base à l'invention consiste à intégrer des surfaces ne pouvant jusqu'à présent pas être exploitées pour la production d'énergie solaire et à les utiliser pour la production d'un courant photovoltaïque à l'aide d'installations photovoltaïques. Ces surfaces sont des zones de circulation publique telles que des parkings, qui ne sont généralement pas entièrement exploités, des zones commerciales temporairement non exploitées, des parkings dans des zones résidentielles, des rues moins fréquentées etc. Toutes ces surfaces ont en commun que des véhicules peuvent se déplacer et être positionnés sur ces dernières. La production et l'accumulation intermédiaire du courant photovoltaïque ont lieu au cours d'une première phase du procédé au moyen d'installations photovoltaïques, qui sont installées sur des véhicules roulant en toute autonomie, lesquels sont positionnés pendant la première phase sur une zone de circulation cible. Dans une deuxième phase du procédé, le véhicule est déplacé jusqu'à un point de raccordement au réseau, par l'intermédiaire duquel l'énergie électrique ayant fait d'objet d'une accumulation intermédiaire est injectée dans le réseau énergétique.
