J'ai fait appel à cet installateur photovoltaïque pour une installation dans le canton de Vaud, et je suis entièrement satisfait de leur service. L'équipe a été professionnelle, ponctuelle et à l'écoute de mes besoins tout au long du processus. L'installation s'est déroulée sans accroc et dans les délais annoncés. Le suivi après la mise en service a été impeccable, avec des explications claires et un accompagnement sur les démarches administratives.
