Ich bin mit der gesamten Auftragsabwicklung, vom ersten Kontakt über die Planung und Bau bis hin zur Abnahme unserer PV- Anlage auf unserem Mehrfamilienhaus sehr zufrieden. Ich kann die esfera Solar AG weiter empfehlen.

Nous avons installés une pompe à chaleur et 33 panneaux photovoltaïques. Nous avons apprécié les services d’Helios à tous les niveaux: proposition initiale claire et complète; travaux exécutés dans les temps; rendements tout à fait satisfaisants (indépendance énergétique); excellent suivi avec actions immédiates en cas de besoin; explications claires concernant les ajustements à effectuer pour obtenir des températures optimales pour le chauffage et le rafraîchissement de notre domicile et pour celle de l’eau sanitaire; et excellent suivi administratif concernant les demandes de subvention. À ce stade, nous n’avons aucune critique à faire au sujet des services d’Helios. Nous recommandons sans hésitation cette entreprise que nous avons choisie après étude approfondie des offres de trois autres entreprises de Genève. Trois autres voisins, qui ont aussi utilisé les services d’Helios, ont exprimé la même opinion concernant la qualité de ces services.
